Enterprise SAS Drive for High-IO Workloads

The Seagate Cheetah 15K.4 ST373454SS is a 74GB 3.5-inch internal hard drive spinning at 15000 RPM with an 8MB cache. It connects via a Serial Attached SCSI (SAS) interface and delivers a 3.5ms average seek time with 2ms latency. This new bare drive targets servers and storage arrays that demand sustained random-access throughput.

Suited for Transaction-Heavy Servers Not

Database servers, email stores and high-frequency logging platforms benefit from the 15000 RPM spindle and low access times. The 74GB capacity and SAS interface make it a poor fit for workstations or NAS units that need terabytes of sequential space or lack a SAS host bus adapter.

SAS Interface Determines Compatibility

The drive uses a Serial Attached SCSI (SAS) interface, so it requires a SAS-capable controller or backplane to operate. A system equipped only with a different interface will not recognise the drive, making the interface the single specification that decides whether this is the right part.

Questions sur cet article

Does the bare-drive package include cables or a mounting bracket, or must they be purchased separately?

The drive ships as a bare unit only; SAS data and power cables plus any 3.5" mounting hardware are not included and must be sourced separately.

The listing shows a single 74 GB 15000 RPM model — how do I decide if this capacity is right for my workload?

Choose this 74 GB capacity when you need the 15000 RPM response of 3.5 ms seek and 2 ms latency for a small, high-transaction dataset; larger datasets will require additional drives.

What does the 15000 RPM speed actually deliver once the drive is installed in a server?

The 15000 RPM spindle yields a 3.5 ms average seek time, 4.0 ms average write time and 2 ms average latency over the SAS interface.
