Enterprise SAS Hard Drive

The Seagate Cheetah 15K.7 ST3600057SS-RFS is a 600GB 3.5-inch internal hard drive built for Tier 1 enterprise storage. It spins at 15000 RPM with a 16MB cache and connects through a SAS 6Gb/s interface. The bare drive uses Seagate PowerTrim technology to dynamically reduce power usage.

Suited For Enterprise Arrays

This drive suits administrators deploying high-performance 3.5-inch Tier 1 storage where the highest capacity in its class and the highest reliability rating in the industry are required. Buyers needing a different interface or a larger cache should look at something else, as this model is fixed at SAS 6Gb/s with 16MB cache.

15000 RPM Spindle Speed

The 15000 RPM spindle speed is the specification that decides whether this is the right part, delivering the rotational performance expected from a Tier 1 enterprise drive. Systems designed for lower RPM drives will not match this throughput profile.

Questions about this item

How much power does the 15000 RPM Cheetah 15K.7 draw during sustained use?

Seagate PowerTrim technology dynamically reduces power usage on the ST3600057SS-RFS, so the 15000 RPM spindle only draws what the workload demands.

Which host interface must my server or controller provide for this SAS 6Gb/s drive?

The drive requires a 6-Gb/s SAS 2.0 port; it will also negotiate down to 4-Gb/s Fibre Channel if that is the only link available.

Will the 3.5-inch ST3600057SS-RFS fit in the same bay and caddy as my older 3.5-inch SAS drives?

Yes, the 3.5-inch form factor matches legacy 3.5-inch SAS bays, so the Cheetah 15K.7 slides into existing caddies without adapters.
