Using Z TurboDrive G2 as second drive in Z840, poor performance, I/O Errors

HP Recommended
Z840
Microsoft Windows 7 (64-bit)

We use a Z840 Workstation with Win7, Dual Xeon E5-2640v4.

For several reason we use a "standard (SATA) ssd" as the boot drive, this is mandatory and can not be changed.

We want to use the Z TurboDrive G2 as an additional disk.

However when we install the drive and the driver from the HP Site (including the Win7 Patch for NVMe) the drive can be accessed but the performance is very low.  For example:

  • the AS SSD Benchmark takes minutes before it is ready to use/to start
  • subversion checkout terminating with disk I/O errors

In the Bios,  "Option Rom Launch Policy" is set to "All Legacy". Setting this to "All UEFI" results to non starting system with an error message like" can not find system disk" or something like that.

 

The only solution by now is to remove the Z TurboDrive

 

The standard SSD is in Bay 0, the HDD is in Bay 1, as far as I see the bays are connected to SAS/SATA 6Gb/s 0 and 1

The Z Turbo Drive is in Slot 1, a Quadro K620 in Slot 2 and a Tesla C2075 in Slot 6

 

Any other solutions to get the Z TurboDrive to work?

if the Z Turbo Drive G2 is based on Samsung technology, try installing this driver

also, loadnig All UEFI in the BIOS will not work with Windows 7.

I work for HP. However, all opinions and comments are my own.

Do you have another computer to test the card in to rule out any setting on your computer?

 

Also, go into the BIOS and change the Boot Order so your C-drive is at top. It seems that the computer spit out the error message when booting since the Z Turbo is set to boot before the C-drive.

 

My Z440 came with the old Z Turbo as a boot drive but i bought a G2 512GB Z Turbo a while ago and once i created a new volume in Disc Management it worked as a charm.  I use Win 10, not Win 7. You can see my reults on the image below.
