300 GB 15 000 RPM enterprise drive
The Seagate Savvio 15K.3 ST9300453SS is a 300 GB 2.5 inch laptop internal hard drive built for enterprise workloads. It spins at 15 000 RPM with a 64 MB cache and connects through a SAS 6Gb/s interface. The bare-drive packaging suits system integrators and replacement scenarios.
Suits high-throughput arrays not portable PCs
This drive targets servers and storage arrays that demand sustained throughput and low latency from a small form factor. The 15 000 RPM spindle and SAS interface serve transactional databases and virtualised hosts. Buyers who need larger capacity or silent operation for a standard laptop should look elsewhere.
SAS 6Gb/s interface dictates compatibility
The single specification that decides fitment is the SAS 6Gb/s interface. The system backplane or controller must support this protocol; a different interface will prevent the drive from functioning. Verify the host connector before purchase.

Questions about this item
Does the ST9300453SS ship with a mounting bracket or cables, or must they be purchased separately?
The drive is supplied as a bare unit only; no bracket, screws or SAS cables are included.
How do I decide between the 15000 RPM 300 GB model and a lower-speed, higher-capacity alternative?
Choose this 15000 RPM 300 GB drive when transactional workloads demand the lowest latency; select a larger, slower drive for bulk storage.
What does the 15000 RPM rating mean for real-world database performance?
The 15000 RPM spindle cuts average rotational latency to roughly 2 ms, giving faster random read and write response for OLTP workloads.
