SKU CH-15DY-VJ0VN

A 900GB 10000RPM SAS drive with 128MB cache and included 2.5" R Series caddy

  • 900 GB capacity stores large datasets
  • 10000 RPM spindle delivers fast data access
  • SAS 12 Gbps interface enables high-throughput transfers
  • 128 MB cache buffers bursts for smoother performance
  • Includes R Series caddy for direct server installation

900 GB 10 000 RPM SAS drive for servers

This new Dell internal hard drive provides 900 GB of storage on a 2.5 inch form factor. It spins at 10 000 RPM and uses a 12 Gbps SAS interface with a 128 MB buffer. The package includes an R Series caddy for installation.

Suits arrays needing fast 2.5 inch SAS storage

The drive fits 2.5 inch SAS bays in Dell EqualLogic and compatible servers that accept the supplied R Series tray. Buyers who need a different capacity or a non-SAS interface should look at other parts. Builders without a 12 Gbps SAS backplane cannot use this unit.

12 Gbps SAS interface decides compatibility

The drive connects through a 12 Gbps SAS backplane and requires a controller that supports this signalling rate. Verify that your server or storage array accepts 2.5 inch SAS drives with the included tray before purchase.

Questions about this item

What does the 10000RPM speed mean for real-world access times?

The 10000RPM spindle reduces average rotational latency to about 3 ms, so random read and write requests complete faster than on slower enterprise drives.

How does the SAS 12Gb/s interface limit actual throughput?

The 12Gb/s SAS link provides a 12 Gbit per second signalling rate; sustained transfers will not exceed the drive’s own media rate.

What does the 2.5in SAS form factor with R Series caddy require for mounting?

The drive fits a standard 2.5in SAS bay and ships with an R Series caddy that slides into Dell EqualLogic R-series chassis slots.
