Dell 146 GB 15K SAS Drive

This Dell 146 GB 3.5" internal hard drive spins at 15000 RPM with a 16 MB buffer. It uses a 3 Gb/s SAS interface and carries Dell part number XK111. The drive is supplied new in OEM packaging and is built for installation inside compatible Dell PowerEdge and PowerVault systems.

Suited for Dell server maintenance

The drive fits Dell PowerEdge 1900, 1950, 2900, 2950, 6900 and 6950 servers as well as PowerVault MD1000 and MD3000 arrays. Buyers who need a different capacity or a non-SAS interface should look elsewhere. It is not intended for desktop PCs or external enclosures that lack a SAS backplane.

3 Gb/s SAS interface decides fit

The single specification that determines compatibility is the 3 Gb/s SAS interface standard. Your controller or backplane must support this exact interface for the drive to function. Verify the interface requirement before purchase.

Questions about this item

Does the Dell 146 GB 3.5" 15000 RPM SAS drive ship with cables, brackets or a tray, or must they be purchased separately?

The drive is supplied in OEM packaging, which typically includes only the bare drive. SAS data and power cables, plus any 3.5" mounting tray or screws required by your server chassis, are not included and must be sourced separately.

The listing shows a single 146 GB capacity with 16 MB cache and 15000 RPM — how do I decide if this version suits my workload?

Choose this 146 GB model when you need the low latency of 15000 RPM spindle speed and 16 MB buffer for transaction-heavy databases or virtualisation on a 3Gb/s SAS backplane; larger capacities at the same speed would cost more, while slower RPM drives would not deliver the same random I/O performance.

What does the 15000 RPM headline figure translate to once the drive is installed in a PowerEdge 1950 or MD3000 array?

In a compatible PowerEdge 1950 or MD3000 the 15000 RPM spindle and 3Gb/s SAS interface deliver sustained throughput near the interface limit and very low average latency, making the drive well suited for high-transaction OLTP workloads and boot volumes where quick seek times matter.
