  • 300 GB capacity stores more enterprise data
  • 15000 rpm spindle delivers faster random access
  • 384 MBps SAS throughput moves large files quickly
  • 50 ms average seek cuts latency
  • Compatible with Dell PowerEdge and PowerVault arrays

Dell HT953 300 GB SAS Drive

The Dell HT953 is a 300 GB 3.5 inch internal hard drive built for Dell PowerEdge servers and PowerVault MD1000 arrays. It spins at 15000 rpm with a SAS 3Gb/s interface and a 16 MB buffer. This new drive suits environments that require the original Dell part number for validated compatibility.

Suits Dell server maintenance and capacity expansion

IT teams maintaining listed PowerEdge models such as the 1950 III, 2950 III, R900 or T300 can use this drive as a direct replacement. It also fits the PowerVault MD1000 storage array. Buyers needing larger capacity, a 6 Gb/s or faster SAS link, or a 2.5 inch form factor should look elsewhere.

The 3 Gb/s SAS interface decides fit

The drive negotiates at 3 Gb/s SAS; controllers that only operate at higher speeds may not support it. Verify the backplane and RAID controller specify 3 Gb/s SAS compatibility before purchase. The 4.50 ms average seek time and 384 MBps maximum external transfer rate reflect this interface generation.

How loud or hot does the 15000 rpm SAS drive run when it operates continuously?

The drive spins at 15000 rpm with a 4.50 ms average seek time and a 16 MB buffer; sustained operation will produce typical high-speed mechanical drive noise and heat for a 3.5 inch enterprise unit.

What controller or backplane must my system provide for the 3 Gbps SAS interface to function?

The drive requires a 3Gb/s SAS host interface; compatible Dell PowerEdge and PowerVault systems include the 1900, 1950 III, 2900 III, 2950 III, 2970, 6850, 6950, 840, 860, R200, R300, R900, R905, SC1430, SC1435, SC440, T100, T105 and T300.

Will the 3.5 inch SAS drive fit in the same drive bays as the drives currently used in a Dell PowerEdge 2950 III?

Yes, the 3.5 inch form factor matches the LFF bays in the PowerEdge 2950 III and the other listed Dell servers and the PowerVault MD1000 array.
