Seagate Introduces IronWolf SSD for NASby Ganesh T S on January 7, 2019 3:45 AM EST
The recent drop in flash pricing has resulted in high-performance SSDs at wallet-friendly price points. NAS units currently being introduced also come with tiering support, allowing the flash-based storage devices to act as caches and improve the performance for real-world workloads. SMBs and SMEs are currently using enterprise SSDs for this purpose, while home consumers / prosumers have no qualms about using consumer SSDs for this purpose. The current trends indicate that there is a market for SSDs specifically targeting the NAS market, as long as it is at the right price point.
Seagate is introducing the IronWolf 110 SATA SSD series at CES 2019, with retail availability slated for late January. Available in capacities ranging from 240GB to 3.84TB, the new SSDs are touted to be enterprise-class. They come with DuraWrite technology, pointing to a Seagate controller based on SandForce technology. The SSDs use 3D TLC and have sustained performance numbers of 560 / 535 MBps sequential reads / writes across the 480GB - 3.84TB capacity class. Detailed specs for each capacity are available below.
The IronWolf 110 SSD series supports 1 DWPD endurance, which implies that Seagate expects them to be used for the typical read-heavy NAS scenarios (which is characteristic of most prosumer / SMB use-cases). Many readers might recognize that the IronWolf 110 seems very similar to the Seagate Nytro 1351, and in fact, they both share the same hardware design - right down to the 1TB and higher models requiring a 12V rail. The controller (Seagate proprietary, with DuraWrite technology similar to the compression scheme used in the SandForce controllers) and PCB are the same. However, the firmware is slightly different to target NAS use-cases and enable easier qualification with NAS OEMs. The IronWolf SSDs also supports the NAS Health Management utility and comes with 2 years of Rescue service (which is not available with the Nytro series).
Seagate is hoping to sell the IronWolf SSDs to prosumers, creative pros, SMB, and SME NAS users. Prosumers and creative professionals with 10G-capable NAS units are bound to benefit from flash-equipped bays. While enterprise SSDs are the way to go for all-flash arrays with write-heavy workloads, other SSD-in-NAS use-cases in the SMB and SME space can benefit from SSDs such as the IronWolf 110. The warranty and bundled data-recovery services are key value additions in this market. However, pricing will be key when it comes to choosing between the IronWolf 110 and other enterprise / high-end consumer SATA SSDs in the market.

Greg100 - Monday, January 7, 2019 - linkYes... we need more SATA SSDs :(
DanNeely - Monday, January 7, 2019 - linkWithin a NAS they're actually still a reasonable option. 2 of them would be fast enough to saturate even a 10gb network connection; and all the prosumer/SMB NASes I've seen with SSD caching have had 2/4 hot swap 2.5" bays not m.2 slots. It's possible that next generation models may offer an m.2 NVME slot instead for size reasons; but because m.2 doesn't support hot swap I wouldn't hold my breath. U.2 and both Intel and Samsung's stick SSD designs do; but nothing in those form factors has trickled down below enterprise products yet, so I'd not expect them in a prosumer device anytime soon.
piroroadkill - Monday, January 7, 2019 - linkWell, in a NAS, yes, they would naturally be SATA, and have to be to be practical. Hell, even all the enterprise solutions are still mostly SATA 6Gbps... I don't think I've even seen SAS 12Gbps SSDs myself yet.
Greg100 - Monday, January 7, 2019 - linkso you can look at:
Western Digital Ultrastar DC SS530 15.36TB
Seagate Nytro 3330 15.36TB
Toshiba PM5-R 15.36TB
Samsung PM1643 15.36TB
all SAS SSDs
Greg100 - Monday, January 7, 2019 - linkSamsung PM1643 and Toshiba PM5-R even 30.72TB
boeush - Wednesday, January 9, 2019 - linkSeriously. At 500+ MBps (note the capital 'B') sequential data rates, we're talking 4+ Gbps network (realistically, more like 5+ Gbps, once you take overhead and contention into account), just to carry one drive's traffic.
Most home/office networks these days are still at or below 1 Gbps...
CheapSushi - Wednesday, June 12, 2019 - linkThen upgrade your home / office network. 2.5G and 5G NICs are relatively cheap now, especially from Aquantia. You don't even need a dedicated switch.
r3loaded - Monday, January 7, 2019 - linkThis press release is useless without prices!! :D
UltraWide - Monday, January 7, 2019 - linkI agree 100%
leexgx - Monday, July 8, 2019 - linki find the data recovery a bit useless on a nas HDD/SSD as it's going to be apart of a raid array so it be useless on its own
