Dell Cheetah 450GB 15K SAS Drive

This 3.5 inch internal hard drive delivers 450GB of storage on a 6Gb/s SAS interface. It spins at 15000RPM with a 16MB buffer and ships new with an R Series caddy tray included. The unit is designed for desktop systems that accept SAS drives.

Suits servers needing fast 15K SAS storage

This drive fits administrators who require 15000RPM performance on a SAS 6Gb/s bus for transactional workloads. It is not for buyers who need larger capacities or systems that lack a SAS host adapter. The 3.5 inch form factor also excludes 2.5 inch drive bays.

15000RPM rotational speed

The spindle speed of 15000RPM is the primary determinant of random I/O latency and sustained throughput for this model. Buyers should verify their controller supports 6Gb/s SAS and that the 3.5 inch tray matches their chassis before purchase.

Questions about this item

What throughput does the SAS 6Gb/s interface actually cap at?

The SAS 6Gb/s interface caps at 6 gigabits per second, which is the maximum signalling rate the controller can sustain with this drive.

What physical space and mounting does the 3.5-inch SAS drive need?

It requires a standard 3.5-inch drive bay and ships with an R Series caddy and tray for direct mounting in compatible Dell chassis.

How is the ST3450857SS installed, and which step is often missed?

Slide the drive into the supplied R Series caddy, secure the screws, then insert the assembly into the hot-swap bay until the lever locks; many forget to fully engage the locking lever.
