Cheetah 15K.4 36.7GB SAS drive

The Seagate Cheetah 15K.4 ST336754SS is a 36.7GB enterprise hard drive spinning at 15000 RPM with an 8MB cache. It uses a Serial Attached SCSI interface and a 3.5-inch form factor. The unit is supplied as a bare drive in new condition.

Suits high-IOPS server workloads

This drive suits administrators maintaining legacy SAS arrays or transactional databases that demand low latency. The 3.5ms average seek time and 2ms latency support heavy random I/O. Buyers needing larger capacities or modern interfaces should look elsewhere.

SAS interface decides compatibility

The Serial Attached SCSI connector is the single specification that determines whether this drive fits your system. A SAS backplane or HBA is required for operation. Verify controller support before purchase.

Questions about this item

How do I install the ST336754SS into a SAS backplane, and which step do people most often miss?

Slide the 3.5" bare drive into a SAS hot-swap bay, connect the combined power-and-data connector, then create and initialise the array in the RAID BIOS before the OS sees the 36.7GB volume.

What maintenance or replacement will the Cheetah 15K.4 need after extended operation?

Plan to replace the drive once its rated service interval is reached or if SMART reallocated-sector counts rise; no field-serviceable parts exist inside the sealed 15000 RPM mechanism.

What limit appears first when the ST336754SS runs sustained write workloads?

The 8MB cache fills quickly, so the 4.0ms average write latency and 15000 RPM rotational speed become the bottleneck before thermal throttling engages.
