Our take on the Dell 400-ALRX 4TB 7200RPM SAS 3.5-Inch Hard Drive

The Dell 400-ALRX is a 4TB enterprise hard drive: a 3.5-inch internal HDD spinning at 7200 rpm over a SAS 12Gb/s interface. It is built for servers and storage arrays, not desktop PCs, since SAS needs a SAS controller rather than a standard SATA port. Against SATA drives of the same capacity it offers dual-port connectivity and higher sustained throughput, but it runs louder and hotter and costs more per terabyte than desktop SATA models. It suits admins replacing a failed drive in a supported Dell PowerEdge or PowerVault system.

Questions and answers

Will this work in a regular desktop PC?
Only if the motherboard or an add-in card has a SAS controller. Standard desktop SATA ports cannot take a SAS drive.
Is it faster than a SATA hard drive?
Sequentially, the 12Gb/s SAS link and 7200 rpm spindle give it an edge over 6Gb/s SATA drives of similar speed. Random access is still hard-drive slow.
Can I use it in a RAID array?
Yes, on a SAS controller that supports RAID. Its dual-port design lets it connect to two paths for redundancy in supported backplanes.
Is it an SSD?
No. It is a mechanical 3.5-inch hard drive with spinning platters, so expect hard-drive speeds, not SSD speeds.
Does it fit a 2.5-inch drive bay?
No. It is a 3.5-inch drive and needs a 3.5-inch bay or an adapter.
Where is the Dell 400-ALRX 4TB 7200RPM SAS 3.5-Inch Hard Drive cheapest?
