The HP Z Turbo Drive is HP's branded high-performance M.2 SSD module designed specifically for HP Z-series workstations, sold here in a 4TB capacity using the PCIe interface in the 2280 (22x80mm) M.2 form factor. It uses TLC NAND flash and supports OPAL2 hardware self-encryption for data-at-rest security, an important feature for workstations handling sensitive engineering, media, or corporate data. Aimed squarely at professional workstation users needing fast large-capacity storage for CAD, video editing, or large dataset work, rather than general consumer laptops or desktops — fitment is specific to compatible HP Z Turbo Drive slots.
