HGST 4TB SAS 12Gb/s 7200 RPM drive

The HGST HUS726040AL4210 is a 4TB 3.5-inch internal hard drive with a SAS 12Gb/s interface spinning at 7200 RPM. It is built for servers and storage arrays that require high-capacity bulk storage on a 12Gb/s SAS fabric. The drive arrives new in original or OEM packaging ready for integration into compatible bays.

Suits SAS-based arrays needing 4TB spindles

This drive fits administrators expanding or refreshing SAS-attached JBODs, RAID enclosures or backup targets that accept 3.5-inch 7200 RPM spindles. Buyers whose backplanes or controllers do not support SAS 12Gb/s cannot use this unit. Systems limited to 2.5-inch bays or requiring solid-state latency should evaluate other media.

SAS 12Gb/s interface decides compatibility

The single specification that determines fit is the SAS 12Gb/s interface paired with a 3.5-inch 7200 RPM form factor. A controller or backplane must provide a native SAS 12Gb/s connection and physical 3.5-inch mounting. Without that interface the drive will not function regardless of capacity or speed.

Questions about this item

What throughput does the SAS 12Gb/s interface cap at in practice?

The SAS 12Gb/s link is rated at 12 Gb/s; the 7200 RPM platters deliver sequential speeds well below that ceiling.

What physical space and tray does the 3.5" form factor require?

It fits a standard 3.5" drive bay and uses the chassis or backplane tray supplied with your server or enclosure.

How is the drive installed and which step is often missed?

Slide the drive into the bay, connect the SAS data and power cables, then ensure the backplane or controller recognises the drive before creating volumes.
