Enterprise 300GB 15K SCSI Drive
The Seagate Cheetah 15K.5 ST3300655LW is a 300GB 3.5 inch internal hard drive spinning at 15000 RPM with a 16MB cache. It connects via a SCSI Ultra320 68pin interface and uses perpendicular recording technology. The bare drive measures 1.0 inch high and is supplied in new condition.
Suits legacy servers needing 68 pin Ultra320
This drive fits servers and storage arrays that require a 68 pin SCSI Ultra320 connection and a 3.5 inch form factor. The 15000 RPM spindle speed and low 2ms average latency support demanding enterprise workloads. It is not for systems that lack a 68 pin SCSI controller or that require a different physical interface.
The 68 pin Ultra320 interface decides fit
The single specification that determines compatibility is the SCSI Ultra320 68pin interface. Only hosts equipped with a matching 68 pin Ultra320 controller can use this drive. Verify the controller and backplane match this exact interface before purchase.

Questions about this item
Does the bare drive include cables or a mounting bracket, or must they be purchased separately?
The drive ships as a bare unit only; 68-pin SCSI cables and any 3.5-inch mounting hardware are not included and must be sourced separately.
The listing shows a single 300 GB capacity — are other capacities available for this model?
This specific model number ST3300655LW is offered only in the 300 GB capacity; different capacities carry different model numbers.
What sustained throughput can I expect from the 15000 RPM mechanism on a real Ultra320 bus?
The 15000 RPM spindle and 16 MB cache deliver low 2 ms average latency, but actual sustained transfer rates depend on the host controller and workload.
