Designed for their Z2 G9 Tower and Z2 G9 Small Form Factor workstations, the 512GB CRU Secure High Performance Storage Module from HP offers a storage capacity of 512GB and requires an HP CRU QX328 Frame/Carrier so that it may be installed into your system. If the QX328 is already installed in your system, you'll only need an HP CRU SHIPS M.2 Spare Carrier.
