146GB 15000 RPM SAS Hard Drive

The Seagate Cheetah ST3146356SS is a 3.5 inch internal hard drive built for enterprise servers and high-performance workstations. It delivers 146GB of storage on a SAS 3Gb/s interface with a 16MB buffer. The 15000 RPM spindle speed provides fast data access for demanding applications. This unit is sold in refurbished condition.

Suits high-IOPS server workloads

This drive suits administrators running transaction-heavy databases or email servers that require low latency and high throughput. It fits 3.5 inch bays with SAS backplanes. Buyers needing more capacity per drive or a different interface should look elsewhere. The refurbished status also means it is not intended for brand-new sealed-stock requirements.

15000 RPM spindle speed

The 15000 RPM rotation rate is the specification that defines this drive's performance tier. It determines the sustained transfer rates and average seek times critical for random I/O workloads. Verify that your controller and backplane support SAS 3Gb/s operation. The 146GB capacity and 16MB buffer are secondary factors once the speed requirement is met.
