Dell 250GB 7.2K SATA 2.5 HDD

The Dell DNTWD is a 250GB 7.2K RPM SATA hard drive in a 2.5 inch form factor. It uses a 512n sector format and operates at 6Gbps. The drive is built for Dell PowerEdge servers including the R230, R330, R430, R530, R630, R730, R730XD, R830, R930, T130, T430 and T630 models.

Upgrade from smaller capacity drives

This drive replaces lower capacity SATA drives in compatible PowerEdge systems. The jump is worth it when you need more storage space for operating systems, applications or data on supported 13th generation servers. It fits the same 2.5 inch bays and uses the same SATA interface.

SATA 6Gbps interface limit

The SATA 6Gbps interface caps the maximum transfer rate of this mechanical drive. Sequential throughput will not exceed the bus limit. Random I/O performance is constrained by the 7.2K RPM rotational speed. The 512n sector format ensures compatibility with older operating systems and controllers that do not support 4Kn sectors.

Questions about this item

Will the 2.5 inch form factor fit the drive bays in a PowerEdge R630?

Yes, the 2.5 inch drive is designed for the 2.5 inch bays used in the PowerEdge R630 and other listed servers.

Does installation require a specific Dell drive carrier or caddy for the PowerEdge R730?

The drive itself is a bare 2.5 inch unit; you must supply the correct Dell hot-plug carrier for the R730 chassis, which is the step often missed.

Is the 512n sector format compatible with the RAID controller in a PowerEdge R430?

The 512 native sector format works with standard RAID controllers in the R430; no advanced format translation is needed.
