Our take on the Seagate ST4000NM0034 Enterprise Capacity V.4 4TB 7200RPM SAS 12Gb/s 128MB Cache 3.5-Inch Hard Drive

The Seagate ST4000NM0034 is a 3.5-inch enterprise hard drive: 4TB, 7200 RPM, 128MB cache, and a SAS 12Gb/s interface with 512e sectors. It is built for servers, NAS boxes and RAID arrays that have a SAS controller, not for a desktop PC. Against SATA drives of the same capacity it adds dual-port SAS and a higher sustained transfer ceiling, but it is louder, hotter and needs a compatible host bus adapter. Owners of SAS backplanes rate it as a solid, long-lived bulk-storage drive.

Questions and answers

Will this drive work in a regular desktop PC?
Only if the PC has a SAS host bus adapter. The SAS connector does not fit a standard SATA port, so a SATA-only motherboard cannot use it.
Is it good for a NAS?
Yes, if the NAS has SAS bays or a SAS controller. It is built for continuous operation, but it is louder than low-RPM NAS drives.
What does 512e mean?
The drive uses 4K physical sectors but reports 512-byte logical sectors, so it works with most modern operating systems and RAID controllers without special formatting.
Can I use it as a boot drive?
It can boot on a SAS controller, but most people use it for data. A smaller SSD is a better system drive.
Is it compatible with my RAID controller?
Check the controller's supported drive list. Most SAS 12Gb/s controllers accept it, and it also runs at 6Gb/s on older SAS backplanes.
