WDC WD40EZAX-xxC8UBx
From Computing Classics Wiki
WD40EZAX-00C8UB0 is a hard drive model created by Western Digital. It is a 4 TB 3.5" CMR hard drive, and was released in 2022 to succeed WD's previous 4 TB Blue models: WD40EZRZ-xxGXCBx and WD40EZAZ-xxSF3Bx. Like other Venice RP2LP models, it uses 2 TB platters which do not require TRIM, unlike the older Venice RP and RP2L. As with other EZAX-suffix models, the WD40EZAX-xxC8UBx breaks the previous trend of 5,400 RPMs having models ending with a Z, most likely to differentiate it from the older EZAZ series. The WD40EZAX-xxC8UBx is currently the only PC class 4 TB drive that is CMR; competiting SMR models include ST4000DM004-2U9104 ad TOSHIBA DT02ABA400/TOSHIBA HDWD240.
