Enterprise 15K SAS Drive
This 146 GB Dell Cheetah 15K.5 spins at 15000 RPM and connects through a 3.5" SAS 3Gb/s interface with a 16 MB buffer. It ships new with zero hours on the platters and includes a black series caddy for hot-swap bays. The drive targets enterprise storage arrays and compatible PowerEdge servers that require high IOPS in a 3.5-inch form factor.
Suited for hot-swap server bays
The SAS interface and hot-swap design make it a direct fit for listed PowerEdge models such as 1950, 2900, 2950, 2970, 6850, 6950, 840, 860, R200, R300, R900, R905, SC140, SC145, SC440, T100, T105 and T300. Builders without a SAS backplane or hardware RAID controller cannot use this drive. Buyers needing more than 146 GB of space or a different physical interface must select another product.
15000 RPM spindle speed
The 15000 RPM rotational speed is the single specification that determines whether this drive meets the performance tier your array expects. Lower-speed drives will not deliver the same random access latency, while higher-capacity alternatives typically run at slower spindle speeds.

Questions about this item
How loud and hot does the 15000RPM SAS drive get when running continuously?
The 15000RPM spindle and 3.5" SAS 3Gb/s interface are built for enterprise duty cycles; the included black caddy helps airflow in PowerEdge bays.
What controller or backplane must my system already have for this 3Gb/s SAS drive to work?
A SAS backplane or PERC RAID card with 3Gb/s SAS ports is required; the drive fits the standard 3.5" hot-swap tray used in listed PowerEdge servers.
Will the ST3146855SS work in my older PowerEdge 2950 alongside existing 10K drives?
Yes, it shares the same 3.5" SAS 3Gb/s interface and hot-swap caddy used across the 2950, 2950iii, 1950, 1950iii and 2900 models.
