3.5 inch SAS hard drive in silver metal caddy

IBM

IBM ST3450857SS 450GB 15000RPM SAS 3.5" internal hard drive

SKU CH-YSSE-4ED2H

Stores 450GB on a 15000RPM SAS drive with an included 3.5-inch system caddy

  • 450 GB capacity stores large enterprise datasets
  • 15 000 RPM spindle delivers rapid transaction response
  • SAS 6 Gb/s interface provides high-throughput connectivity
  • 5 inch form factor fits standard server bays
  • Includes IBM system caddy for tool-less installation

450 GB 15K SAS enterprise drive

This new IBM internal hard drive delivers 450 GB of storage on a 3.5-inch SAS 6 Gb/s interface spinning at 15000 RPM. It ships with the IBM system caddy for direct installation in compatible servers or storage arrays. The unit weighs 2.0 pounds and carries a one-year warranty.

Suits high-IOPS server workloads

The 15000 RPM spindle speed targets transactional databases, virtualization hosts and other latency-sensitive applications that benefit from fast mechanical access. Buyers who need larger capacities, lower power draw, or silent operation for desktop use should consider alternatives. The SAS interface requires a compatible controller or backplane.

15000 RPM rotational speed

This single specification determines whether the drive meets the performance profile of the intended workload. Systems built for high-throughput sequential traffic or archival storage will not utilise the spindle speed advantage. Verify that the host platform supports 3.5-inch SAS 6 Gb/s drives before purchase.

Spurningar um þessa vöru

What does the 15000 RPM speed mean for real-world performance on the ST3450857SS?

The 15000 RPM spindle reduces average rotational latency, so random read and write operations on the 450GB platters complete faster than on slower-spinning drives.

What does the SAS 6Gb/s interface cap in practice for this drive?

The SAS 6Gb/s link limits the maximum burst transfer rate to 6Gb/s; sustained throughput will be lower and depends on the 15000 RPM mechanics.

What does the ST3450857SS physically need to fit and mount in a system?

It requires a standard 3.5-inch drive bay and the included IBM system caddy or tray for secure mounting.
