Enterprise storage drive

The Dell XTH17 is a 900GB 2.5" SAS internal hard drive spinning at 15000 RPM. It uses SLC NAND flash memory and connects through a 6Gb/s SAS interface. The drive is supplied as a bare unit in manufacturer packaging. It is built for Dell EMC storage systems including MD14xx enclosures.

Suited for high-throughput arrays

This drive fits storage administrators who need low-latency performance in compatible Dell EMC enclosures. The 15000 RPM spindle speed supports demanding I/O workloads. Buyers who require larger capacity per bay should consider other options. Systems without SAS backplanes or hot-swap bays cannot use this drive.

15000 RPM spindle speed

The 15000 RPM rotation rate is the defining specification for transaction-heavy workloads. It determines the drive's random-access latency and sustained throughput ceiling. Verify that your enclosure supports 15K drives and 6Gb/s SAS before purchase.

Questions about this item

What comes in the box with the XTH17 and do I need a separate caddy or cable?

The drive is supplied as a bare unit only; a 2.5" SAS hot-swap caddy and SAS data cable must be sourced separately for installation.

Which capacity and speed version of the XTH17 should I choose for a Dell EMC MD14xx enclosure?

This model is the single 900 GB 15000 RPM SAS variant built for the MD14xx series; no other capacity or speed is offered under part XTH17.

How does the 15000 RPM spindle speed affect real-world performance in a storage array?

The 15000 RPM rotation delivers low average latency for high random I/O workloads typical of transactional databases on the MD14xx platform.
