Enterprise Storage Drive

The Dell R755K is a 2TB 3.5" internal hard drive built for enterprise storage workloads. It uses a SAS 6Gb/s interface and spins at 7200 RPM with a 16 MB buffer. The unit ships with a tray for direct installation into compatible Dell PowerVault servers. Condition is refurbished.

Capacity and Headroom

Two terabytes provide room for bulk data, backups and near-line archives in a single bay. The 7200 RPM spindle delivers consistent sequential throughput for streaming workloads. Random I/O performance will taper off under heavy multi-user database loads. The SAS 6Gb/s link caps maximum transfer rate at six gigabits per second.

Build and Connectors

A low-profile 3.5" form factor fits standard drive bays while the included tray secures the drive in hot-swap chassis. Dual SAS ports enable multipath redundancy when the backplane supports it. The 6Gb/s interface is backward compatible with 3Gb/s controllers. Refurbished units have been tested for reliable operation in server environments.

Questions about this item

Will the 3.5" SAS 6Gb/s drive work in a server that only has SAS backplanes?

Yes, the drive uses a standard SAS 6Gb/s interface and 3.5" form factor, so it will install directly into any compatible SAS backplane or hot-plug tray.

How can I verify the R755K is running at 7200 RPM after installation?

Check the drive's reported rotational speed in the server BIOS, RAID controller utility, or operating system disk information — it should read 7200 RPM.

Does the R755K come with a mounting tray or do I need to buy one separately?

The supplier description states the drive includes a tray for PowerVault servers; no separate tray purchase is required for compatible bays.
