Our take on the Seagate ST4000NM025B 4TB SAS 12Gb/s 7200RPM 3.5-Inch Hard Drive

The Seagate ST4000NM025B is a 4TB enterprise hard drive in the 3.5-inch form factor. It spins at 7200 RPM and connects over a 12Gb/s SAS interface, not SATA, so it needs a SAS controller or backplane. It is built for servers, NAS boxes and storage arrays that run around the clock, not for a desktop PC. Against SATA drives of the same capacity it offers dual-port SAS connectivity and enterprise-grade duty ratings, but it is louder and hotter than low-RPM nearline drives.

Questions and answers

Will this drive work in a regular desktop PC?
Only if the motherboard or an add-in card has a SAS controller. The drive uses a SAS interface and will not connect to a standard SATA port.
Is it compatible with a SATA backplane?
No. SAS drives need a SAS backplane or controller. Some SAS controllers accept SATA drives, but the reverse does not work.
What is the difference between this and a SATA 4TB drive?
The SAS interface supports dual-port connections and is aimed at enterprise arrays. A SATA drive is simpler and cheaper to run in a home PC.
Is it good for a home NAS?
It works in a NAS with SAS bays, but it is louder and draws more power than low-RPM NAS drives. Check that your enclosure supports SAS first.
Does it come with cables or a controller?
No. It is a bare drive. You supply the SAS cable, backplane and controller.
