Dell 2TB SAS 12Gb/s 7.2K HDD
This Dell 4DDFP is a 2TB 2.5-inch internal hard drive with a SAS 12Gb/s interface, 7200 RPM spindle speed and 128MB cache. It uses 512e sector formatting and ships with a mounting tray for direct installation in compatible bays. The drive is supplied new in OEM or retail packaging.
Suited for SAS storage arrays and servers
This drive fits systems that accept 2.5-inch SAS drives running at 12Gb/s and need 2TB of capacity at 7200 RPM. Buyers whose platforms only support SATA or who require a different capacity should select a matching model. The 512e format also requires controller or operating-system support.
SAS 12Gb/s interface decides fit
The single specification that determines compatibility is the SAS 12Gb/s interface combined with the 2.5-inch form factor. Only controllers and backplanes that explicitly support SAS 12Gb/s can use this drive; a SATA-only connection will not work.

Küsimused selle toote kohta
How do I install the 2.5" SAS drive into a 3.5" bay using the included tray?
Mount the drive in the supplied tray with the four side screws, then slide the tray into the 3.5" bay until the SAS connector seats firmly on the backplane.
What component will need replacement after several years of 7200 RPM operation?
The spindle motor and actuator bearings are the first parts to wear under continuous 7200 RPM use, so plan for a full drive replacement when SMART reallocated-sector counts rise.
At what point does the 128 MB cache stop absorbing write bursts during sustained workloads?
Once incoming writes exceed roughly 128 MB the cache fills and throughput drops to the native 7200 RPM media rate, so sustained transfers run at the physical disk speed.
