Samsung NVMe tech powers HP Z Turbo SSD

— 11:48 AM on April 13, 2015

Add HP to the list of SSD providers with next-gen NVMe hotness. The company announced its Z Turbo Drive G2 at the NAB show today. Like Intel's 750 Series, the drive combines four PCIe Gen3 lanes with the NVM Express protocol. Zee Turbo is "powered by Samsung NVMe technology," and it looks like a tweaked version of the M.2-based SM951 slotted into an adapter card for HP's Z-series workstations

HP specs the drive for up to 2150MB/s sequential reads and 1550MB/s writes, matching the peak stats for the AHCI-based SM951. But the random I/O ratings are higher: 300k IOps for reads and 100k IOps for writes, up from 130k and 85k IOps, respectively. Samsung teased an NVMe version of the SM951 at its SSD Global Summit last summer, and the Z Turbo may be related to that product.

Configurations are available with 256GB or 512GB of MLC flash. The larger of the two is guaranteed to survive 292TB of total writes, while its sibling is officially good for only 146TB. The smaller drive is also limited to 1260MB/s sequential writes, which is still more than double the peak speed of SATA SSDs.

HP says the Z Turbo will arrive in June at $399 for 256GB and $699 for 512GB, a steep per-gig premium over the 750 Series street prices. The Samsung SM951 isn't sold through typical e-tail channels, and the versions available through RAM City use the AHCI protocol, so it's harder to make a direct comparison there.
