1.2 TB 10K SAS Drive

This 2.5 inch internal hard drive provides 1.2 TB of storage on a SAS 12 Gb/s interface. It spins at 10 000 RPM and uses SLC NAND flash memory. The drive is supplied new in retail or OEM packaging. It is built for desktop systems that support the SAS standard.

Who This Suits

The drive suits servers or workstations that require a 12 Gb/s SAS connection and 10 000 RPM performance. It is not for systems that lack a SAS controller or backplane. It is also not for users who need a 3.5 inch form factor. Buyers without SAS infrastructure should look at other interfaces.

Deciding Specification

The SAS 12 Gb/s interface is the single specification that decides compatibility. Your host must provide a SAS 12 Gb/s port and a 2.5 inch bay. Without that interface the drive cannot operate. Confirm the interface before purchase.

Questions about this item

What drive bay size does the 2.5" form factor require?

The 2.5 inch form factor fits a standard 2.5 inch drive bay or a 3.5 inch bay with an adapter bracket.

How is the SAS 12Gb/s interface connected during installation?

Attach the SAS data and power cables to the drive connectors, then secure the drive in the bay; the common error is seating the SAS plug incompletely.

When should the 1.2TB 10000 RPM drive be replaced?

Replace the drive if SMART attributes report reallocated sectors, seek errors, or if sustained throughput drops below expected levels.
