Dell ST3300555SS 300GB 15K SAS Drive

This Dell ST3300555SS is a 3.5-inch internal hard drive with a 300GB capacity and a 15000RPM rotational speed. It connects via a SAS 3Gb/s interface and includes a 16MB buffer. The drive ships new with an R Series tray for direct installation into compatible Dell bays.

Suited for SAS servers needing 15K speed

This drive suits administrators replacing a failed 15K SAS disk in existing Dell PowerEdge or Precision systems that use the R Series caddy. It is not for buyers whose hardware only supports slower spindle speeds or smaller form factors. It also does not meet the needs of users requiring larger capacities for archival storage.

SAS 3Gb/s interface decides compatibility

The single specification that determines fit is the SAS 3Gb/s interface combined with the 3.5-inch form factor and included tray. The host backplane and controller must support this exact SAS generation and physical connector. Without that match, the drive cannot communicate or mount securely in the chassis.

Questions about this item

The listing shows FW956 and 0FW956 — do I choose one part number or are they the same drive?

Both part numbers refer to the identical ST3300555SS unit; you will receive the same 300 GB 15 000 RPM SAS drive with the included tray.

What does the 15 000 RPM rating mean for actual throughput in a server?

The 15 000 RPM spindle speed combined with a 16 MB cache delivers high random IOPS and low latency for transaction-heavy workloads.

The drive uses a 3 Gb/s SAS link — what practical ceiling does that impose?

The 3 Gb/s SAS interface caps the maximum burst transfer rate at 3 Gb/s, so sustained throughput will not exceed that limit.
