Enterprise SSD with 256-bit AES encryption

The Axiom 728737-B21-AX is a 240 GB enterprise solid-state drive designed for servers and storage arrays that require hardware-based data protection. It presents a standard SATA 600 interface and fits into 3.5-inch hot-swap bays using the included carrier.

Capacity and headroom

The drive offers 240 GB of usable space with sequential reads up to 500 MB/s and writes up to 260 MB/s over SATA 600. These speeds suit read-heavy workloads such as boot volumes, logging or caching, while write-intensive databases will saturate the interface more quickly.

Build integration

A 2.5-inch mechanism inside a 3.5-inch carrier allows direct installation in hot-swap backplanes without extra adapters. The SATA connection simplifies cabling and controller compatibility, and the 256-bit AES encryption secures data at rest without consuming host CPU cycles.

Questions about this item

Will the 2.5 inch drive in its 3.5 inch carrier fit the hot-swap bays of my older SATA 600 server?

Yes, the 3.5 inch carrier matches standard hot-swap trays and the SATA 600 interface is backward compatible with earlier SATA controllers.

How can I verify the 256-bit AES encryption is active after installation?

The drive self-encrypts all data by default; use your RAID controller or OS disk utility to confirm the encryption status shows enabled.

Does the 728737-B21-AX ship with mounting screws or only the carrier?

The drive comes mounted in the 3.5 inch carrier ready for hot-swap insertion; screws are not included.
