Dell 342-5524 1.2TB SAS Drive

The Dell 342-5524 is a 1.2TB 2.5 inch internal hard drive built for SAS 12Gb/s interfaces. It spins at 10000 RPM with a 64MB buffer and ships as a bare drive in OEM packaging. This component targets server and storage-array upgrades where the original Dell part number is specified.

Suits SAS 12Gb/s bays needing 10K speed

This drive fits 2.5 inch bays that accept a SAS 12Gb/s connection and require 10000 RPM performance. It is not for systems limited to slower interfaces or lower spindle speeds. Buyers needing a larger capacity or a different physical form factor should look at other parts.

Interface is SAS 12Gb/s

The single specification that decides compatibility is the SAS 12Gb/s interface. Verify the host controller or backplane supports this exact protocol before purchase. The 10000 RPM spindle and 64MB cache are secondary to the interface match.

Questions about this item

Should I choose the 1.2TB 10000 RPM SAS model or a different capacity?

This drive provides 1.2TB capacity at 10000 RPM with a 64MB buffer on a SAS 12Gb/s interface, suited for high-transaction server workloads.

What does the 10000 RPM rating mean once the drive is installed in a server?

The 10000 RPM spindle speed delivers low average latency for random I/O, improving response times in database and virtualisation workloads on compatible PowerEdge servers.

The listing shows SAS 12Gb/s — what throughput does that actually cap at in practice?

The SAS 12Gb/s interface supports up to 12Gb/s link speed, though sustained transfer is limited by the 10000 RPM mechanical performance and 64MB cache.
