Seagate Ironwolf 525 NAS NVMe SSD Revealed

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

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.
