Seagate Ironwolf 525 vs 510 NAS NVMe SSD Comparison

29 décembre 2021 à 01:10

Comparing the Seagate Ironwolf 510 vs Seagate Ironwolf 525 – Which Should You Use in Your NAS?

The Seagate Ironwolf series of NAS media has been around for a few years now and what started as a rebranding of their ‘NAS’ labelled series has now become a multi-tiered series of Hard drives and SSDs. Recently Seagate introduced a new entry into their Ironwolf SSD series with the 525 NVMe SSD. Presented as a higher bandwidth supporting alternative NVMe SSD to the Ironwolf 510 (released back in March 2020), the Ironwolf 525 is a PCIe Gen 4 NVMe SSD that arrives in slightly larger capacities, much higher performance and still allowing backwards compatibility with PCIe Gen 3 m.2 slots in your NAS. So, with the release of this newer, faster and widely supported NVMe SSD, should you still consider buying the Seagate Ironwolf 510 at all? Well, yes! The older Ironwolf 510 still arrives with a few rather unique architecture and design choices that are not available in the Ironwolf 525 and today I want to take a close look at each of these NAS focused SSDs and help you decide which one you should buy for your NAS drive in 2021/2022.

Important – It is worth remembering that the two SSDs in today’s comparison are m.2 NVMe in architecture and although PCIe Gen 4 is compatible with Gen 3 and old, they will not suitable for NAS drives with M.2 SATA connections. We have seen more modern NAS systems released in the last few years abandon m.2 SATA in favour of its PCIe counterpart, but Seagate provides SATA alternatives in their Ironwolf series. Examples of SATA SSDs for NAS can be found HERE on Amazon. Additionally, it is worth highlighting for the later stages of testing in this comparison, I was only able to obtain the 240GB model of the Ironwolf 510, so although the performance shown is low (and much lower than the Ironwolf 525 as expected in most cases) it is particularly low because the test drive is the 240GB Model. Please follow the official performance specifications in the table below for a better indication of how comparable capacity drives would differ.

How do the Seagate Ironwolf 525 and Seagate Ironwolf 510 SSD Compare on Specs?

Seagate are well known for their wide ranges of hard drive and SSD media, as well as both being pioneers of NAS server focused SSDs for caching and flash storage. Although SSDs are all built to a similar ground-level architecture, they will often have their later development shifted in favour of a specific targetted use. This is not a big surprise and much like the cutlery in your kitchen draw, they might be similar but one tool is much better at some tasks than others – ever tried using a spreading butter with a meat-claver? Or stirring tea with a ladle? The Seagate Ironwolf 525 and Seagate Ironwolf 510 SSD are NAS targetted and although the performance is good, the true stand out factor in this design is the durability of the drive. SSDs for use in NAS systems will in most cases be used for caching and that means a very frequent turnover (i.e. data wrote, updated, deleted, repeat) daily as the demands of client users and devices change. Both of these SSDs arrive with a high level of durability and workload rating, but the Seagate Ironwolf 510 and Seagate Ironwolf 525 definitely have differing ideas of preliminary architecture and what that price tag is being spent on. Let’s look at the shared base-level SSD architecture of each SSD (available on every capacity):

Below Specifications are taken from official brand sources, data sheets and reputable sources (real-world tests we performed ourselves are a little lower in the article):

Seagate uses 3rd party controllers and NAND manufacturers for the most part in their ranges, but are still generally quite top tier providers. The release time difference between the Seagate Ironwolf 510 and Seagate Ironwolf 525 makes an impressive difference here in terms of the hardware on offer on either SSD, with the more recently released Seagate Ironwolf 525 having notably superior connectivity, NAND quality and overall performance. Both Seagate Ironwolf SSDs features 3 years of forensic level data recovery services though (which caching NAS users might want to have in the event of ‘trapped data’ during write caching operations and a critical system failure/power-cut) which is very unique to the brand. However, overall the Seagate Ironwolf 525 has the superior architecture here. Below is how the building blocks of the Seagate Ironwolf 525 and Seagate Ironwolf 510 result in throughput, IOPS and Durability at each capacity tier (based on officially provided figures):

Overall, it should come as no surprise that the Seagate Ironwolf 525 is the notable leader here in practically all official benchmarks over the slightly older Seagate Ironwolf 510 SSD, thanks to that improved architecture. Most notably in write performance and IOPS in general, it had a clear lead even in the lowest available capacities. Of course, these are officially provided performance figures and represent maximums based on the highest available hardware at the time of release. Let’s take a look at how these two SSDs compare in our own tests.

How Did the Seagate Ironwolf 510 and Seagate Ironwolf 525 Compare in OUR Tests?

Moving away from the official performance stats provided by WD and Seagate, I wanted to see how the Seagate Ironwolf 510 and 525 compared in my own tests. Testing of these two SSDs will be broken down into 3 main parts, a CrystalDisk Benchmark test, Atto Disk Benchmark Test and an AJA media test. In each test, the SSD was in the 2nd storage slot (i.e not the OS drive). Each test was conducted three times and the system was left for 1 minute between tests to allow the SSD time to stabilize. The specifications of the test machine are:

Test Machine:

  • Windows 10 Pro Desktop System
  • Intel i5 11400 Rocket Lake – 6-Core 2.6/4.4Ghz
  • 16GB DDR4 2666MHz Memory
  • Intel B560M mATX Motherboard
  • OS Storage, Seagate Firecuda 120 SSD
  • Test SSD connected to Secondary PCIe Gen 4×4 M.2 Slot

CrystalDisk 1GB Test File – Read, Write, 70/30% Mixed and IOPS Performance

CrystalDisk is still highly regarded as one of the most reliable tools for measuring storage media performance. Though it does create somewhat high-end results that may not be truly indicative of your own real-world setup, it can be used to display maximum potential throughput and IOPs at each tier. The first test for the Seagate Ionwolf 510 and Seagate Ironwolf 525 was on a 1GB test file:

Seagate Ironwolf 525

Seagate Ironwolf 510 SSD

Overall Winner: The Seagate Ironwolf 525

CrystalDisk 4GB Test File – Read, Write, 70/30% Mixed and IOPS Performance

The next test was to perform the same parameters in CrystalDisk on the Seagate Ironwolf 525 and Seagate Ironwolf 510, but this time with a 4GB test file (larger files may result in higher sequential performance, but lower comparative IOPS):

Seagate Ironwolf 525

Seagate Ironwolf 510 SSD

Overall Winner: The Seagate Ironwolf 525

ATTO DiskBenchmark 256MB Test File – Read, Write

Switching things up, I then moved testing the Seagate Ironwolf 510 and Seagate Ironwolf 525 over to ATTO disk benchmark. A far more detailed tool that spreads performance testing over different file and block sizes. I started with the smallest ‘full range’ test file of 256MB (as smaller would reduce the range of block sizes). Here is how each SSD compared:

Seagate Ironwolf 525

Seagate Ironwolf 510 SSD

Overall Winner: The Seagate Ironwolf 525

ATTO DiskBenchmark 4GB Test File – Read, Write

Sticking with ATTO DiskBenchmark, I then moved the testing of the Seagate Ironwolf 525 and Seagate Ironwolf 510 onto a x16 bigger test file of 4GB. This would certainly shift where the peaks in performance would sit and hopefully produce a clearer disparity between these two SSDs:

Seagate Ironwolf 525

Seagate Ironwolf 510 SSD

Overall Winner: The Seagate Ironwolf 525

AJA 1080i Media Test 1GB Test File – Read, Write

I then switched to AJA, a popular media testing tool for video formats. Most SSDs will suffer over-saturated Memory/DRAM/SDRAM as sustained large file tests go on. The 1GB file test of AJA on the Seagate Ironwolf 525 and Seagate Ironwolf 510 is still a small enough value not to be a problem though and we chiefly focused on the disk playback/reads graph to see how they compared in peak performance and also throughout the transfer:

Seagate Ironwolf 525

Seagate Ironwolf 510 SSD

Overall Winner: The Seagate Ironwolf 525

AJA 1080i Media Test 16GB Test File – Read, Write

Then we used a much, MUCH heavier test in AJA of 16GB on the Seagate Ironwolf 510 and Seagate Ironwolf 525. Unsurprisingly this can often overflow the SSD cache/memory on board and result in a dip in performance as the SSD bottlenecks internally. So, when conducting this test, we are looking at peak performance AND how long the SSD maintained that performance before a potential dip. Here is how these two SSD compared:

Overall Winner: The Seagate Ironwolf 525

Seagate Ironwolf 525 vs Seagate Ironwolf 510 SSD – The Results

It is probably no surprise that the Seagate Ironwolf 525 is the better drive overall. With performance in throughput and IOPS that outshine the Ironwolf 510 in both Read and Write on a PCIe Gen 3 m.2 slot,  then upping the ante considerably by allowing 2-3x that performance via a PCIe 4 M.2 Connection. That said, the adoption of PCIe 4 x4 as the connection of choice in a NAS is currently very low indeed, largely down to the large availability of PCIe 3 SSDs in the market AND the simply fact that manufacturers would need to dedicate notably more CPU PCIe Lanes to a Gen 4 connection than they would a Gen 3 (lanes that might be better used in improved NAS external connectivity or other hardware services). Additionally, the Seagate Ironwolf 510 has higher durability in all capacities, as well as a smaller 240GB capacity for those considering caching on much smaller systems/HDDs. The Seagate Ironwolf 525 is still the better SSD choice over the Ironwolf, but if you see it at a bargain price, have intensive data re-writes in mind or are looking for a smaller SSD, it’s still a viable option. And don’t forget, both SSDs include that 3 year Rescue Data Recovery service and Seagate Ironwolf Health Management that is accessible via your NAS Storage Manager (supported on Synology, QNAP, Asustor and more).

The Seagate Ironwolf 525 NVMe SSD Wins on:

  • Higher Performance (Read & Write), even in a PCIe Gen 3 Slot
  • Supports PCIe Gen 4 M.2 NVMe SSD Slots
  • Better Sustained Performance
  • Massively Higher IOPS ratings (Read and Write)
  • Takes Advantage of a several gen higher Phison Controller

The Seagate Ironwolf 510 NVMe SSD Wins on:

  • Higher Durability at 0.9-1.0 DWPD on all Capacities (IW 525 t 0.7 DWPD)
  • Smaller 240GB Capacity Available
  • PCIe Gen 3 is still at more than 95% adoption on NAS systems compared with PCIe 4
  • Been available longer, so might have more flexible pricing online

WD Red SN700 vs Seagate Ironwolf 510 SSD for NAS Comparison

15 décembre 2021 à 01:22

Comparing the Seagate Ironwolf 510 vs WD Red SN700 SSD – Which Should You Use in Your NAS?

Over the last few years of NAS Drive releases from brands like Synology, QNAP and Asustor, we have seen most Prosumer and SMB releases arriving with support of either M.2 NVMe SSD bays, or PCIe slots that allow you to add this feature in the system’s lifespan. The appeal of SSD cache has grown considerably in recent years, as the demands in speed and responsiveness of the data on NAS drives has grown considerably. Despite the well-established fact that SSDs are faster than Hard drives, there is no ignoring that the available capacity and price point of hard drives makes them ultimately more viable and desirable in a NAS than SSDs. However, SSD Caching serves as a nice middle ground, allowing you to enjoy the bigger and lower cost hard drive RAID storage pools, but also adding two or more individual SSDs to bolster the system in performance. The Seagate Ironwolf 510 and WD Red SN700 are SSD’s that are designed with NAS use in mind and can be used in the process of write caching (where data is written to the faster performing SSD first, then migrated over to the HDDs), read caching (whereby more frequently accessed data is copied over to the SSDs in order to seed up their access by connected clients) or both together. There are numerous other SSD caching methods and protocols, but these are ultimately the most common and today I want to help you decide which NAS SSD you should install in your NAS Drive. There is around an 18-month release date difference between these two SSDs and although both are M.2 NVMe PCIe Gen 3×4 SSDs, there is a large degree of difference in their architecture to take into consideration. So let’s compare the WD Red SN700 and Seagate Ironwolf 510 and see which one deserves your cache.

It is worth remembering that the two SSDs in today’s comparison are m.2 NVMe in architecture and although PCIe Gen 4 is compatible with Gen 3 and old, they will not suitable for NAS drives with M.2 SATA connections. We have seen more modern NAS systems released in the last few years abandon m.2 SATA in favour of its PCIe counterpart, but both Seagate and WD both provide SATA alternatives in their Ironwolf and WD Red series. Examples of SATA SSDs for NAS can be found HERE on Amazon.

How do the WD Red SN700 and Seagate Ironwolf 510 SSD Compare on Specs?

Both WD and Seagate are well known for their wide ranges of hard drive and SSD media, as well as both being pioneers of NAS server focused SSDs for caching and flash storage. Although SSDs are all built to a similar ground-level architecture, they will often have their later development shifted in favour of a specific targetted use. This is not a big surprise and much like the cutlery in your kitchen draw, they might be similar but one tool is much better at some tasks than others – ever tried using a spreading butter with a meat-claver? Or stirring tea with a ladle? The WD Red SN700 and Seagate Ironwolf 510 SSD are NAS targetted and although the performance is good, the true stand out factor in this design is the durability of the drive. SSDs for use in NAS systems will in most cases be used for caching and that means a very frequent turnover (i.e. data wrote, updated, deleted, repeat) daily as the demands of client users and devices change. Both of these SSDs arrive with a high level of durability and workload rating, but the Seagate Ironwolf 510 and WD Red SN700 definitely have differing ideas of preliminary architecture and what that price tag is being spent on. Let’s look at the shared base-level SSD architecture of each SSD (available on every capacity):

As you might know, WD develops practically all of their SSDs ‘in-house’ and feature proprietary NVMe controllers, subsidiary company NAND (in this case Sandisk) and this allows them to be able to control availability and pricing in a way that most other SSD brands cannot. Seagate uses 3rd party controllers and NAND manufacturers for the most part in their ranges, but are still generally quite top tier providers.

Then we used a much, MUCH heavier test in AJA of 16GB on the Seagate Ironwolf 510 and WD Red SN700 SSD. Unsurprisingly this can often overflow the SSD cache/memory on board and result in a dip in performance as the SSD bottlenecks internally. So, when conducting this test, we are looking at peak performance AND how long the SSD maintained that performance before a potential dip. Here is how these two SSD compared:

WD Red SN700 vs Seagate Ironwolf 510 SSD – The Results

It will come as little surprise that in the case of comparing the WD Red SN700 and Seagate Ironwolf 510, the more recently released and more modern architecture WD SSD was the victor in the majority of tests (both official 1st party and my own). Although it has taken WD almost a year and a half to release a competitor NAS NVMe SSD to Seagate’s entry, it is unquestionable the better performing drive as it takes advantage of numerous newer innovations in SSD architecture that have been developed and released in that time. The Durability across the entire range of the Ironwolf 510 series and three years of inclusive forensic level data recovery do make the Seagate Ironwolf an attractive choice in 2021, but in NAS use, general use and performance overall, the WD Red SN700 wins the day.

The WD Red SN700 NVMe SSD Wins on:

  • Overall Read Performance
  • Overall Write Performance
  • 4K IOPs
  • Price Point per GB/TB
  • Capacity (4TB Max)

The Seagate Ironwolf 510 NVMe SSD Wins on:

  • Data Recovery Services (Rescue)
  • On-Board Over Provisioning
  • TBW and DWPD Overall

New Seagate 20TB Ironwolf Pro and EXOS Hard Drive Revealed

9 novembre 2021 à 14:00

Seagate 20TB Irownolf Pro and EXOS Hard Drives for NAS/Server

It’s been in the pipeline for a while (originally revealed way back in Jan 2020 with hopes of arriving in Q1 2020 and developed deployed in the background since) that Seagate has had a planned 20 Terabyte 3.5″ SATA and SAS hard drive for 24×7 server use – but data center users may be pleased to hear that it is looking like an end of 2021 release. Arriving in their popular Ironwolf Pro NAS server and EXOs data centre-class series, these are among the biggest commercially available drives in the market and are a real feather in the cap for Seagate – who recently announced their roadmap for reaching 20TB, 50TB and a staggering 100TB by 2030 – see video here. Both the EXOs and Ironwolf Pro 20TB hard drives are arriving with helium seal design, high workload rating, CMR architecture and maximum drive speeds reported at 285MB/s. For those concerned with early adoption, 20TB Hard drives have already been in usage with the likes of major cloud companies and providers (for example Facebook, Google, Amazon Web Services, Azure etc) for well over a year now, so this tier of storage is by no means in its early days of development. These are going to be some serious kit (with the EXOS series arriving in SATA/SAS and onboard encrypted hardware versions) that are going to be available to the average company. Let’s take a closer look at each of these drives, how Seagate hit the big 2-0 and whether these should be your next big business storage purchase to hit the Petabyte mark?

What Are the Hardware Specifications of the Seagate Ironwolf Pro 20TB NAS Hard Drive?

The Seagate Ironwolf drive media range still continues to be one of the biggest in the NAS market, arriving at a better price point than most, yet still providing top-level performance and endurance. Alongside the inclusive business-level data recovery services included with the Ironwolf HDDs (so 5 years standard warranty and 3 years of inclusive data recovery coverage in the event of failure), this drive is also heavily geared towards the 24×7 use of NAS systems in both home and business. This new 20TB NAS hard drive is part of the Seagate Ironwolf Pro series, so that means an impressive 300TB workload rating, 5-year warranty, 7200RPM, 256MB cache and perfect for much, MUCH larger rackmount arrays. Although not likely to be the quietest drive, this will likely be largely dwarfed by the active cooling systems of even the most conservative business NAS solution. Below is a breakdown of those specifications in full:

Seagate Ironwolf Pro 20TB NAS Hard Drive

Product Family SEAGATE IRONWOLF Pro
Capacity 20TB
Standard Model Number ST20000NE000

Warranty 5yr

Unfortunately, this drive will not be seeing a non-PRO release, given the restructuring of Seagate in their capacities across PRO/non-PRO ranges. Additionally, the Seagate Ironwolf Pro will likely be quite a pricey drive, both for those enterprise build specs, the capacity and simply the exclusivity of the drive on the market.

What Are the Hardware Specifications of the Seagate Ironwolf Pro 20TB NAS Hard Drive?

The Seagate EXOS series, although often compared and similar to that of Seagate Ironwolf due to it’s server design and deployment, is a drive with a much larger focus of heavy, HEAVY workloads. The Seagate 20TB EXOs hard drive, much like the previous capacities before it, arrives with a hefty 550TB workload limit (TBC!), choice of SATA or SAS interfaces, 7200 PRM and a massive 2.5 million hours MTBF. As you would expect from an enterprise-grade drive, there is also a choice of self-encrypted drive (SED) versions that also features FIPS support (government class encryption). Below is a breakdown of the SATA/SAS EXOs 20TB hard drives and how they compare:

SPECIFICATIONS SATA DRIVE – 20TB X20 Series

SAS DRIVE – 20TB X20 Series

Product Family EXOS X20 EXOS X20
Capacity 20TB 20TB
Standard Model Number ST20000NM007D ST20000NM002D
SED Model ST20000NM000D ST20000NM003D

Vibration, Nonoperating: 2 to 500Hz (Grms) 2.27 2.27
Shock, Operating 2ms (Read/Write) (Gs) 40 40
MTBF 2.5Million 2.5Million
Power-On Hours per Year 8760 8760
Warranty 5yr 5yr

Although lacking the Rescue data recovery services of the Ironwolf Pro HDDs, the Seagate EXOS 20TB has an incredibly sharp focus on robust deployment and touch-of-a-button responsiveness (i.e low latency) which is vital in considerably larger data center/hyperscale environments.

When will the Seagate EXOS and Ironwolf Pro 20TB HDDs Be Released?

Seagate has been particularly firm on their stance about introducing 20TB hard drives into their portfolio before the close of 2021 (despite HDD market-changing factors, SUCH as Chia, Hardware shortages and the pandemic) and all indications so far would heavily indicate the availability of the new Seagate Ironwolf Pro and EXOS 20TB hard drives landing (not just announcing, but being business-available) on time. Despite SSD prices and NVMe SSD technology growing in its appeal and affordability these last few years, Seagate still seems fantastically committed to hard drive technology as still the best option for BIG data this decade and these new 20TB drives are going to be a big step for any business looking at the realistic need to store petabytes of data. Pricing for each version of the 20TB Seagate HDD series is almost certain to be a sore point for some, but Seagate almost certainly knows that people will pay it.
