Silver 3.5 inch SAS hard drive with model label ST3300656SS

Seagate

Seagate ST3300656SS 300GB 15000RPM SAS 3.5" internal hard drive

SKU CH-SHBS-FZ0N6

High-performance 300GB 15,000RPM SAS drive with 16MB cache for demanding server workloads

  • 15000 RPM spindle speed cuts latency for transaction-heavy workloads
  • 300 GB capacity stores OS, logs and databases on a single drive
  • SAS 3 Gb/s interface connects directly to enterprise controllers and backplanes
  • 16 MB cache absorbs burst writes to sustain throughput under load
  • 5 inch form factor fits standard server bays and hot-swap trays

Enterprise 15K SAS drive

The Seagate Cheetah 15K.6 ST3300656SS is a 300GB 3.5-inch internal hard drive spinning at 15000RPM. It connects through a 3Gb/s SAS interface and carries a 16MB cache buffer. The drive is supplied new and targets servers and storage arrays that require high transaction rates.

Suits high-IOPS workloads.

This drive suits database logging, online transaction processing and tier-0 storage where low latency and sustained random I/O matter. Buyers who need multiple terabytes per spindle or who lack a SAS backplane and HBA should look elsewhere.

15000RPM spindle speed decides fit

The 15000RPM rotational speed is the single specification that determines whether this drive matches the workload. It delivers the access times required for write-intensive enterprise tasks but offers only 300GB of capacity per unit.

Questions about this item

At what rotational speed does the 300 GB SAS drive reach its sustained-throughput ceiling?

The spindle runs at 15000 RPM, so sustained transfer rates are limited by that mechanical speed and the 3 Gb/s SAS link.

How much heat and noise should I expect when the Cheetah 15K.6 runs continuously in a server chassis?

At 15000 RPM with a 2.0 pound 3.5" form factor, the drive produces noticeable whine and warmth; plan for active airflow across the top cover.

Which host interface must my system already provide for this ST3300656SS to function?

A SAS 3 Gb/s backplane or HBA with a standard 3.5" drive bay and SAS power connector is required.
