HP Z Turbo Drive G2 256GB PCIe NVMe

The HP Z Turbo Drive G2 is a 256GB internal solid state drive built for HP Z Workstations. It uses the M.2 form factor and connects through a PCIe Gen3 x4 interface with an NVMe controller. This drive targets professionals who need faster storage than SATA can provide.

PCIe Gen3 x4 bandwidth ceiling

The PCIe Gen3 x4 link sets a practical throughput limit above 2GB/s for sequential transfers. Random read performance also improves significantly over SATA because the NVMe controller reduces command overhead. SATA-connected drives cannot reach these speeds because the bus itself becomes the bottleneck.

Replaces SATA SSDs in Z Workstations

This drive upgrades systems that currently use SATA SSDs and have an available M.2 slot wired for PCIe Gen3 x4. The jump is worth it when workloads involve large file transfers or heavy random read activity that saturate the SATA bus. Buyers whose platforms lack a compatible M.2 slot cannot use this drive.

Questions about this item

Is the 256GB capacity the only option for this drive?

The product is listed as a 256GB model. No other capacities are mentioned in the specifications.

What read speed can I expect from the PCIe Gen3 x4 interface in my workstation?

The interface enables performance levels greater than 2GB/s for sequential reads when installed in a compatible HP Z Workstation.

Does the M.2 form factor use the NVMe protocol or SATA?

This drive uses the NVMe controller technology over a PCIe Gen3 x4 connection, not the SATA bus.
