22TB SAS enterprise drive
The Western Digital Ultrastar DC HC580 WUH722422AL5201 is a new 22TB 3.5-inch internal hard drive built for enterprise workloads. It spins at 7200 RPM and connects through a SAS 12Gb/s interface with a 512MB cache. Helium-sealed construction and flash-enhanced architecture support 24x7 operation in data centres, cloud arrays and high-performance computing clusters.
Suits RAID arrays and secure archives
This drive fits builders who need high-capacity, self-encrypting storage for RAID arrays, backup targets or object-store tiers. The SED feature meets strict data-protection policies without software overhead. Buyers who require a different interface protocol or non-SED firmware should look at something else.
SAS 12Gb/s interface decides fit
The single specification that determines compatibility is the SAS 12Gb/s interface. Your controller, backplane or HBA must support this exact protocol to recognise the drive and negotiate full throughput. Without a matching SAS host the drive will not function.

Preguntas sobre este artículo
Does my server need a SAS 12Gb/s backplane to install this 22TB Ultrastar DC HC580?
Yes, the drive uses a SAS 12Gb/s interface and requires a compatible SAS controller or backplane that supports 12Gb/s speeds and 3.5-inch form factor bays.
Will this 7200 RPM enterprise drive work in an older SAS 6Gb/s storage array I already own?
The SAS 12Gb/s interface is backward compatible with 6Gb/s and 3Gb/s SAS infrastructure, so it will operate at the slower link speed of the older array.
How can I confirm the 512MB cache and helium-sealed design are active after installation?
Check the drive identification data via your RAID controller BIOS or OS utilities; it will report model WUH722422AL5201 with 512MB cache, and SMART attributes will show helium-sealed health status.
