SKU CH-YSXJ-C1X05

Enterprise 2.5" SAS hard drive delivering 900GB at 10000RPM with 128MB cache and included server caddy

  • 900 GB capacity stores large enterprise datasets
  • 10000 RPM spindle delivers fast random access
  • 12 Gb/s SAS interface moves data at high throughput
  • 128 MB cache absorbs burst workloads
  • 5 inch form factor fits dense server bays

Enterprise 900GB SAS drive

This 2.5-inch internal hard drive delivers 900GB of storage on a 12Gb/s SAS interface. It spins at 10000RPM with a 128MB cache and ships new with a Dell PowerEdge caddy. The unit is built for enterprise server and storage arrays.

Suited for RAID arrays, not home PCs

The drive targets administrators expanding Dell EqualLogic or PowerEdge systems that accept 2.5-inch SAS disks. Buyers who need a consumer desktop drive, a laptop upgrade, or an interface other than SAS should look elsewhere.

12Gb/s SAS interface decides fit

The single specification that determines compatibility is the 12Gb/s SAS connection. Your backplane, controller or server chassis must support this exact interface and the 2.5-inch form factor for the drive to function.

Questions about this item

How often will the 128MB cache 900GB 10000RPM SAS drive need replacement under typical enterprise workloads?

Enterprise-class 10000RPM SAS drives are built for continuous operation; replacement timing depends on workload intensity and environmental conditions rather than a fixed interval.

Which limit appears first during sustained writes — the 12Gb/s SAS interface bandwidth or the 10000RPM mechanical throughput?

The 10000RPM mechanical throughput typically saturates before the 12Gb/s SAS interface reaches its maximum, making the spindle speed the first bottleneck.

How much heat and noise does the 2.5" 900GB 10000RPM SAS drive add when it spins continuously in the included caddy?

A 2.5" 10000RPM enterprise drive generates noticeable heat and audible seek noise during all-day operation; adequate chassis airflow is required to keep temperatures in spec.
