Scaled Endurance 15.36 TB SAS SSD

The Seagate Nytro 3350 is a 2.5-inch internal solid-state drive built for enterprise storage arrays. It connects through dual SAS 12 Gb/s ports and offers 15.36 TB of usable capacity. The drive is rated for one full drive write per day and a total endurance of 28000 TB written. It supports continuous 24x7 operation with a 2.5 million hour MTBF rating.

Read-intensive workloads.

This drive suits read-heavy applications such as content delivery, web hosting and virtualised storage tiers where the 2100 MBps sequential read speed and 165000 random read IOPS matter. The 1100 MBps write speed and 20000 random write IOPS make it a poor fit for write-intensive logging, database redo logs or high-frequency checkpointing that would exceed the 1 DWPD rating. Buyers needing higher write endurance should look at drives with a higher DWPD figure.

Dual-port SAS enables multipath redundancy

The two SAS 12 Gb/s interfaces provide multipath I/O for path failover and load balancing in dual-controller enclosures. This redundancy keeps volumes online during a controller or cable fault without extra host-side configuration. The 1.2 GBps external transfer rate matches the 12 Gb/s link speed, so the drive does not become a bottleneck in a balanced SAS fabric.

Questions about this item

What host interface does my server need to run the Nytro 3350 15.36 TB drive?

The drive uses a dual-port SAS 12 Gb/s interface, so the system must provide a compatible SAS backplane or HBA that supports 12 Gb/s signalling.

Can I mix the Nytro 3350 with older 6 Gb/s SAS drives in the same enclosure?

Yes, the drive is backward compatible with 6 Gb/s SAS infrastructure; it will negotiate the lower link speed while delivering up to 2100 MB/s read and 1100 MB/s write internally.

Which SMART attribute shows the Nytro 3350 is healthy after installation?

Monitor the percentage-used endurance indicator; with 1 DWPD and 28000 TB total endurance it should remain near zero during normal 24x7 operation.
