Enterprise read-intensive SSD for servers and arrays

The Seagate Nytro 3350 XS1920SE70055 is a 1.92TB 2.5-inch drive built for enterprise NAS, DAS, workstation and data-centre server deployments. It uses a dual-port SAS 12Gb/s interface with 3D eTLC NAND and carries both Seagate and IBM labelling for broad system compatibility.

1 DWPD endurance rating defines the write budget

Rated at 1 drive write per day, the drive is tuned for read-intensive workloads such as backup, archiving, big data analytics and cloud storage tiers. Sustained sequential read reaches 2200 MB/s while sustained sequential write reaches 1550 MB/s.

Power-loss protection

Enhanced error correction and power-loss protection guard against corruption during unexpected shutdowns. The self-encrypting drive feature protects data at rest without host-side encryption overhead. MTBF is rated at 2500000 hours.

Questions about this item

What does the 2200 MB/s sequential read figure mean once the drive is installed in a server?

That rating comes from sustained sequential workloads on a 12 Gbit/s SAS link; real throughput depends on the controller, queue depth and workload mix, so mixed random I/O will be lower.

What does the SAS 12Gb/s interface cap in practice?

The dual-port 12 Gbit/s SAS connection provides two independent 12 Gbit/s lanes; each lane tops out near its line rate, so total system bandwidth depends on how the host balances I/O across both ports.

What does the 2.5-inch form factor need to fit or mount in a chassis?

It uses the standard 2.5-inch SAS drive dimensions and dual-port connector, so it slides into any 2.5-inch hot-swap bay or caddy that accepts enterprise SAS SSDs.
