Dell 400-AJPK 300GB SAS drive

This Dell 400-AJPK is a 300GB 2.5 inch internal hard drive that uses a SAS 12Gb/s interface and spins at 10000 RPM. It arrives as a bare drive with a hot-swap tray for tool-less installation. The unit is sold new and carries the original Dell part number 400-AJPK.

Suits hot-swap bays needing 10K performance

This drive fits servers or storage arrays that accept 2.5 inch SAS drives and can negotiate a 12Gb/s link. It is not for systems limited to 6Gb/s SAS backplanes, nor for chassis that only support 3.5 inch form factors. Buyers who need larger capacities or solid-state speeds should consider other options.

SAS 12Gb/s interface governs compatibility

The single specification that decides fitment is the SAS 12Gb/s interface combined with the 2.5 inch hot-swap form factor. The host backplane must support 12Gb/s SAS signalling and provide a matching 2.5 inch bay with hot-swap capability. Without that interface and bay combination the drive cannot be installed or operated.

Questions about this item

How much power and heat does the 10000 RPM SAS drive generate during continuous operation?

The 2.5" 10000 RPM SAS drive consumes more power and produces more heat than slower desktop drives; ensure your chassis cooling and power supply can handle the higher sustained load.

What controller or backplane is required to run this 12Gb/s SAS drive?

You need a SAS host bus adapter or RAID controller with a 12Gb/s SAS port and a compatible 2.5" hot-swap backplane or drive cage that accepts the Dell 400-AJPK tray.

Will the 12Gb/s SAS interface negotiate down to 6Gb/s if my existing backplane only supports 6Gb/s?

Yes, the 12Gb/s SAS drive will automatically negotiate to 6Gb/s on a 6Gb/s backplane, allowing it to operate alongside older SAS drives at the lower speed.
