200GB SATA II MLC enterprise SSD

This refurbished HP 636595-B21-R drive delivers 200GB of storage in a 2.5-inch form factor. It uses MLC memory and connects through a SATA II interface. The unit was first listed by the manufacturer in 2019.

Suits servers needing MLC endurance on SATA II

IT teams maintaining legacy arrays that require 2.5-inch MLC drives will find this capacity a direct match. Builders deploying new platforms that demand SATA III speeds or higher-density flash should evaluate other options.

SATA II interface determines host compatibility

The drive operates on the SATA II bus, so the backplane or controller must support that link speed. Confirm the interface before installation to avoid throughput mismatches.

Questions about this item

Does the HP 636595-B21-R ship with a caddy, screws or cables, or must they be bought separately?

The drive is supplied as the bare 2.5 inch SSD only; any drive carrier, mounting screws or SATA data and power cables need to be sourced separately.

When should I choose this 200 GB MLC model over a different capacity or memory type?

Select this 200 GB MLC version when you need a balance of write endurance and cost for mainstream enterprise workloads on a SATA II interface.

What does the SATA II interface mean for actual throughput once the drive is installed in a server?

The SATA II link runs at 3 Gb/s, so the drive's sequential read and write speeds will be limited to the bandwidth of that interface in a real machine.
