When Seagate purchased LSI's flash business, it acquired a range of PCI Express SSDs wearing "Nytro" branding. Those drives currently come in PCIe add-in card, M.2 stick, and U.2 2.5" form factors, and today Seagate is announcing that it is releasing 2TB drives in that family. The company says this announcement marks an industry first in that the 2TB Nytro XM1440 M.2 NVMe SSD is "the highest-capacity enterprise-class" drive of its type.
The Nytro family encompasses a bunch of drives, but the news today primarily concerns the XF1440 and XM1440. The XF1440 is a 2.5" NVMe SSD that connects to the host with a U.2 connector, while the XM1440 is essentially the same thing in an M.2 gumstick. Both drives are available as either "endurance-optimized" or "capacity-optimized" models.
The capacity-optimized models come in 480GB, 960GB, and 1920GB sizes. Meanwhile, the endurance-optimized versions trade a bit of storage for a three-full-drive-write-per-day rating ten times the 0.3-drive-write-per-day rating of the capacity-optimized models. Those disks come in 400GB, 800GB, and 1600GB sizes. The same drives are also available for systems lacking U.2 or M.2 connectors as the Nytro XP7102, a PCIe add-in card only available in 800GB or 1600GB endurance-optimized flavors.
Like most NVMe SSDs, the drives offer impressive performance, at least on reads. Sequential reads scale up to 2500 MB/s, while Seagate rates the drives at up to 240,000 IOPS for random reads. Write performance is less inspiring, at "only" 900 MB/s sequential and 40K IOPS on the endurance-optimized models, or 15K IOPS on the capacity-optimized drives. Seagate warranties the drives for 5 years in either case.
