An 18TB SAS hard drive in the 3.5-inch form factor with a 7.2K rpm spindle on a 12Gbps SAS interface, carrying Dell part number R20GG and built on a Western Digital drive, maker model WUH721818AL5200.
In a RAID 6 set, two drives’ worth of space goes to parity, so plan around usable rather than raw capacity. Dell-labelled drives carry Dell firmware, which is what PowerEdge RAID controllers expect to see. Once a replacement is fitted, the RAID controller rebuilds the array onto it, and larger drives take longer to rebuild. A spare of the same model cuts the time an array spends degraded when a drive fails. It is meant for PowerEdge servers and PowerVault arrays with 3.5-inch SAS bays. Fit it in the caddy that suits your server generation; caddies differ between generations. In a hot-plug bay with a redundant RAID level, a failed disk can usually be swapped while the server keeps running. Use the part number R20GG to confirm the drive matches the one already in your system.
Condition is certified refurbished, and each drive is inspected, bench-tested and wiped in Johannesburg.
