Silver 3.5 inch SAS hard drive with green circuit board

Seagate

Seagate ST3450857SS 450GB 15000RPM SAS 3.5in internal hard drive

SKU CH-N2K3-A7VGF

A 450 GB 15,000 RPM SAS drive with 16 MB cache for high-throughput server workloads

  • 450 GB capacity stores large server workloads
  • 15000 RPM spindle delivers fast transaction response
  • SAS 6 Gb/s interface moves data at high throughput
  • 16 MB cache buffers bursts for smooth I/O
  • 5 inch form factor fits standard drive bays

Server-grade 15K RPM SAS drive

The Seagate Cheetah 15K.7 is a new 3.5-inch internal hard drive built for enterprise servers and storage arrays. It spins at 15000 RPM and connects through a 6 Gb/s SAS interface with a 16 MB buffer. The 450 GB capacity suits transactional databases and high-throughput workloads.

Suited for high-IOPS environments

This drive targets administrators who need sustained random-access performance from a 15K spindle. Buyers who need larger capacities, quieter acoustics or lower power draw should evaluate other form factors. The SAS interface requires a compatible controller or backplane.

15000 RPM spindle speed decides fit

The 15000 RPM rotational speed is the single specification that determines whether this drive meets the latency and IOPS targets of the deployment. Verify that the host system supports 3.5-inch SAS drives and can provide adequate cooling for 15K operation.

Domande su questo articolo

What comes in the box and what must be purchased separately?

The drive ships as a bare 3.5in SAS unit. A SAS host bus adapter or RAID controller with a 6Gb/s port, SAS data and power cables, and a 3.5in drive bay are required and sold separately.

Which capacity and speed version should I choose for a transaction-heavy server?

This single model provides 450GB at 15000RPM with a 6Gb/s SAS interface and 16MB cache, the only combination available under part number ST3450857SS.

What does the 15000RPM figure mean for real-world database throughput?

The 15000RPM spindle and 6Gb/s SAS link deliver sustained transfer rates suited to high-IOPS workloads such as OLTP databases and logging arrays.
