Seagate Ironwolf 525 NAS NVMe SSD Revealed

20 septembre 2021 à 15:25

Seagate PCIe Gen 4 NVMe for NAS on its Way – The Ironwolf 525 SSD

Continuing their reputation for bringing new media releases to the market before everyone else, Seagate seemingly has a PCIe Gen 4.0 NVMe SSD in the pipeline for NAS/SAN server use in their Ironwolf series, known as the Seagate Ironwolf 525. Although little is publically know about this new SSD, the Ironwolf 525 has already begun to appear on numerous stock management and distribution sites in Europe, so this seems to indicate a likely release before the end of 2021. Seagate was one of the first brands in storage media to introduce a server dedicated class of SSDs for home and prosumer users (with a U.2/SAS series already in place for enterprise in their Nytro series of course) in both SATA and NVMe m.2, however even in this early leak of information, a few unique or interesting details have already emerged. So, let’s go through everything that we know so far and whether the Seagate Ironwolf 525 SSD will deserve your cache* later in 2021/2022

Seagate Firecuda 530 PCIe 4.0 NVMe SSD Review Here https://nascompares.com/2021/08/09/seagate-firecuda-530-ssd-review-the-score-to-beat

*I’ll get my coat…..

The Seagate Ironwolf 525 SSD – What Do We Know?

As mentioned, details on specifications of the Seagate Ironwolf 525 NVMe SSD are remarkably thin on the ground. Clearly, release and a formal reveal should not be too far ahead, as even a casual search online reveals that a number of European sites are listing the drive:

As it stands, there are no official datasheets for the Seagate Ironwolf 525 SSD available, but a lot of the specifications that ARE available (across all listing sites), as well as going by the Seagate model ID naming convention used in the Ironwolf 510 and Firecuda seemingly indicate the following:

  • Seagate Ironwolf 525 NVMe SSD
  • Available in 500GB, 1TB and 2TB Capacity
  • PCIe Gen 4.0 x4 Architecture
  • NVMe 1.3 (TBC)
  • 2280 M.2
  • 3D TLC NAND (96L or 176L TBC)
  • 0.98/1.0 DWPD (TBC)
  • 850/1800/3600 TBW (TBC)
  • 1.8M Hours MTBF (TBC)
  • 5 years Warranty
  • Rescue Data Recovery Services (2/3yrs TBC)

Of course, these should be taken with a huge grain of salt until a formal release is made, but even tentatively, compared against the Seagate Ironwolf 510 Gen 3 SSD, the Ironwolf 525 is much more comparable to the Firecuda 520 in architecture and almost certainly will feature the Pison E16 controller. A VERY important factor to keep in mind right now is that in Autumn 2021, there are very, VERY few PCIe Gen 4.0 equipped servers (and practically zero M.2 PCIe 4×4 equipped systems). PCIe Gen 4 upgrade cards are very gradually appearing, but this seemingly looks like it will be a much later winter 2021/2022 hardware change from the big names in NAS, SAN and custom servers. Therefore, as appealing as the Seagate Ironwolf 525 PCIe Gen 4×4 SSD sounds right now, it is worth remembering that very few server systems will be able to fully unlock its potential and if you are considering the Ironwolf 525 for a NAS/Server released before Summer 2021, then you would likely be better off opting for the current Seagate Ironwolf 510 NAS SSD which is PCIe Gen 3×4 and has incredibly high durability taken into account.

The Seagate Ironwolf 525 SSD – Price & Availability

Details regarding when this drive will be available to buy are incredibly thin on the ground. As mentioned, the low number of PCIe Gen 4.0 server systems, the continued high suitability of the Ironwolf 510 and the storage media market that is only starting to bounce back from over a year of shortages (at least!) all add up to the Seagate Ironwolf 525 not being a drive that needs to arrive in a hurry! The current PCIe Gen 4.0 favourite SSD, the Seagate Firecuda 530 and 520 still continue to support the existing PCIe4 client market in desktop and laptop forms, but for NAS (and indeed all server types) this switch is still very much ‘in progress’. Prices however seem to be a little clearer, with individual distributions sites appearing to agree on the pricing for each capacity at the moment of 500GB being €104 (€125 inc.TAX) 1TB at €173 (€208 inc.TAX) and 2TB arriving at €359 (€430 inc.TAX). Of course, these prices are subject to change, but do serve as an early guide on the pricing of the Seagate Ironwolf 525 and how that price sits with the Ironwolf 510 and Firecuda 520 that are currently available. We will keep an eye on this and update you on the Ironwolf 525 as we learn more, so stay subscribed!

SSD Caching On A NAS? What Is It and Should You Use It?

17 septembre 2021 à 01:17

Should you bother with SSD cache in on a NAS?

Most modern generation network attached storage NAS drives include the option of utilising SSD cache, which promises to improve file access and general system performance in a number of ways. Is by no means a new concept and has existed in one shape or form for more than a decade in modern server utilisation. However, in order to take advantage of SSD caching on your NAS, there are a number of hurdles that will often increase the price point of your ideal solution and potentially lower the capacity that you can take advantage of long-term. This leads many users into wondering whether SSD caching is anywhere near as beneficial as brands like Synology and QNAP would have you believe. So today I want to discuss what SSD caching is, who can benefit from it, who definitely won’t and hopefully help you decide whether you should consider SSD caching on your NAS.

What is SSD caching on a NAS?

The majority of NAS systems are comprised of multiple hard drives supported in a single enclosure that are combined together in efforts to increase capacity, performance and redundancy in a configuration commonly known as RAID (Redundant Array of Independent Disks). The more hard drives you have, the larger and more advantageous the RAID configurations you can create. However, these only marginally increase the performance available to you, multiplying performance on hard drives by a factor of the total number of hard drives. Ultimately, you are still using hard drives for your file system which will always pale in comparison to the performance available via solid-state drives SSD but this group of HDDs will result in higher throughput than any single hard drive. The obvious alternative of course is to replace all of the hard drives in your NAS with SSD and therefore reap the benefit of both SSD performance and RAID combination advantages. However, in practice, the main reason that no one does this is that the price point of SSD is significantly higher than hard drives and although the performance benefits would be greatly increased, the price would rise 5-10x times higher at least and the total available capacity would be significantly reduced – as general commercial and SMB SSDs currently max out at 4TB capacity, rather than the 18/20TB available in modern hard drives. NAS/Servers being fully populated with SSDs is still done though on less common setups which are highly enterprise and more commonly known as flash servers – fast but fantastically expensive!

SSD caching was designed as a hybrid storage media solution to this dilemma and involves pairing a small percentage of SSD storage space together with a larger area of hard drive storage space. Typically recommended at around 10% SSD to 90% hard drive, the NAS system will gradually learn over time which files on the total storage system are the ones being accessed most frequently. These files can range from tiny system files, indexes, thumbnails, directories and minor background data, all the way through to larger files that are in shared drives between multiple users, OS-related files that live on a central server and website files that are constantly being referenced for your domain (depending on the I/O configuration of your SSD cache). As the system constantly learns which files are the ones being constantly accessed, copies of these files are made on the area of SSD cache and in future when these files are requested by connected hardware clients, these faster-accessing copies will be targeted instead. Although this is a large oversimplification of the process, it is generally accurate. Not to be confused with tiered storage, which moves commonly accessed files to areas of SSD (not making a copy in 2 locations), SSD cache has numerous advantages and disadvantages that many users would do well to learn before embracing this storage media process. Let’s discuss this a little further, as there are multiple types of SSD cache options available from most modern brands.

What is Read SSD Caching on a NAS?

The easiest but least beneficial type of SSD cache for a mass is read-only cache. This can be implemented with even a single SSD and much like the description above, involves the system moving copies of the most frequently accessed data onto the SSD. Read-only SSD cache on a NAS prevents editing or modifying of files that are being accessed on the area of the cache. Read-only cache is only of benefit to users who are accessing larger databases of preset data that is not often modified and although improves access to these more common files, limits the overall benefits of SSD caching in most NAS systems long term. Also known/referred to as Write-around SSD caching, this too writes data to the primary storage first instead of to the cache. This gives the SSD cache time to analyze data requests and identify the most frequently and recently used data. The SSD cache efficiently caches high priority data requests without flooding the cache with infrequently accessed data

What is Write Caching on a NAS?

Write Caching on a NAS can actually be broken down into two types. The first, Write-through SSD caching, writes simultaneously to the SSD cache area and to primary storage. The cache enables faster data retrieval, while the primary storage writes safely retains the data even if a system interruption affects the cache (eg a power failure). Write-through SSD caching does not require additional data protection for the cached data (so you can use one or more SSD in a Single/RAID 0 Config), but does increase write latency (i.e write time). The alternative is Write-back SSD caching, which writes ONLY to the SSD area first, then confirms that a block is written to the SSD cache, and the data is available for usage before writing the block to the main storage RAID array of HDDs afterwards. The method has lower latency than write-through, but if the cache loses data (i.e. critical system failure, power loss, etc) before the data writes to primary storage, that data is lost. Typical data protection solutions for write-back SSD caching are redundant SSDs or mirroring (i.e. MASSIVELY recommended or enforced that SSDs in a Write Through config are in a RAID 1/5 at the very least).

The application and customization of SSD caching in modern NAS software are incredibly diverse and in most cases, you can create a very bespoke SSD caching config for your system that integrates one or more caching read/write methods taht are best suited to your system setup, data types and access routines. So, now you know what SSD caching is and the types that most commonly exist, what are the advantages and disadvantages?

Guide to Seagate SSDs Guide to WD SSDs

What Are The Advantages of SSD Caching on a NAS?

The benefits of SSD caching on a NAS are often tough to measure, as the resulting improvements are the culmination of multiple smaller improvements at once. So the benefits are more often FELT than actually seen, as latency will be reduced throughout the overall access of the data on your NAS. Compressed data like thumbnails, indexing information and system reference files that a NAS will refer to in a given process will be turned around much quicker in the background and therefore will reduce wait times on instructions given by you to the NAS. Typically larger databases in scale rather than individual file volume will reap the most benefits, and therefore the advantages of SSD caching on a NAS are:

  • Faster Access to Larger databases made up for many smaller files
  • More cost-effective than an all-SSD system
  • Write-Cache/Write-Through Caching benefits more traditional one-way activity
  • Cache is largely self-managed, so once set up, will choose/drop important cached data on its own
  • The bulk of Porsume/SMB and higher NAS hardware arrive with dedicated SSD Cache bays, so no loss of traditional storage bays
  • SSD caching is becoming increasingly available on ARM-powered devices

What Are The Disadvantages of SSD Caching on a NAS?

It is very important to understand that SSD caching is not some kind of magic wand that will suddenly make your NAS significantly faster. Indeed, SSD caching will be of little to no use to the majority of home and prosumer users on a smaller scale, as larger files will rarely be moved to areas of cache and most home users will use a NAS predominantly for multimedia use, large-scale backups and surveillance in home or office environments. Not only do these processes use significantly less frequently accessed data (more likely resulting in the CREATION of new data) but as they are often more ad-hoc in nature, aside from some early write-caching, the benefits of SSD caching will be all but useless to you. Then there is the added cost, added system overhead resource use and more. Here are the main disadvantages of SSD caching on a NAS:

  • Increases Costs of your Storage Setup
  • Not all NAS M.2 NVMe SSD bays are the same bandwidth, some are capped to 1000-2000MB/s, bottlenecking some SSDs
  • Cache Data benefits are HEAVILY dependant on storage user type/files
  • Some Cache methods (i.e Write-Back) store data in the cache, THEN move to the system as it is written and susceptible to loss in the event of a power failure

M.2 SSD Vs SATA SSD Caching on a NAS?

As mentioned in the introduction to today’s article on SSD caching, the majority of NAS drives in the market right now support SSD caching. However, though many have adopted NVMe M2 SSD bays to allow users dedicated ports to do this, many other more affordable or smaller scale NAS hardware systems (2-Bays, ARM CPU devices, etc) still require the end-user to occupy existing traditional hard drive media bays for SSD media for caching instead. Obviously, this can be a significant disadvantage to your overall total maximum capacity when losing main storage bays to smaller capacity SSD for caching. But is there any difference in performance benefits by opting for significantly faster M2 NVMe PCIe SSDs for caching over traditional SATA SSD? Well yes and no. The data stored on the SSD cache has the potential to be delivered to the NAS physical interfaces at whatever maximum speed the SSD can output, so NVMe SSD will always technically push that data faster. Likewise, as the library of cached data and metadata is compiled in the system’s usage, its creation will be markedly faster on the NVMes than SATA SSD which is going to be advantageous to numerous types of write-caching. However, if you are only utilising one or more gigabit ethernet connections, then the difference felt by the end-users when read-write caching is applied between either SSD media type will be practically unnoticeable. Therefore the noticeable differences between SATA SSD and M2 NVMe SSD caching only really apply to use us who take advantage of a larger external network interface or are running larger database operations inside the NAS architecture, containers and virtual machines.

It is also worth remembering that despite many NAS systems releasing with NVMe SSD bays, their architecture might not have sufficient PCIe lanes on the CPU and assigned chipset to allow maximum NVMe SSD performance. In short, not all NVMe slots are created equal and although you may purchase a 3000-4000MB per second SSD for your NAS and its caching, don’t be surprised if that PCIe m.2 physical revision caps your performance much lower (I strip-down of the hardware inside most home/prosumer NAS systems like the DS920+, TS-473A or Lockerstor 4 will show that the M.2 NVMe slots inside can only reach 1000-2000MB/s at most as they are PCIe 2×2, PCIe 2×4 or PCIe 3×2. In short, NVMe SSD slots for caching are a good thing and can certainly provide better performance over SATA SSD in a number of ways, just be aware that sometimes the way you use it or the hardware of the NAS itself will potentially limit this.
