1.2 TB SAS 12Gb/s 10K RPM Drive

The Seagate Exos 10E2400 is a 1.2 TB enterprise hard drive with a 12Gb/s SAS interface and 10,000 RPM spindle speed. It uses a 2.5-inch form factor and includes a 128 MB buffer. The drive is supplied new in bare-drive packaging.

Suited For SAS 12Gb/s Bays

This drive suits servers and storage arrays that accept 2.5-inch SAS drives running at 12Gb/s. It is not for systems that only support slower SAS link rates or larger 3.5-inch drive bays. Buyers needing higher capacity than 1.2 TB should consider other models.

12Gb/s SAS Interface Decides Fit

The single specification that decides compatibility is the 12Gb/s SAS interface. The host controller and backplane must support this exact signalling rate for the drive to operate at its rated performance.

Questions about this item

Will the 2.5-inch form factor and .6-inch height fit my server drive bay?

The drive measures 2.5 inches wide, 4 inches deep and .6 inches high, matching the standard 2.5-inch enterprise bay dimensions.

What is the correct way to connect the SAS 12Gb/s interface during installation?

Attach a SAS 12Gb/s cable or seat the drive in a SAS backplane; the dual-port connector must be fully engaged for both channels to initialise.

When should I expect to replace the 128 MB cache buffer or the drive itself?

The 128 MB buffer is integrated and not user-replaceable; plan to replace the entire drive when SMART attributes indicate wear or after the rated workload limit is reached.
