Closed Identifies 1 of 2 hard drives

[ChuckM]

Hi Steve,

I'm not sure if this is similar to issue:
Pending fix - No drives found | GRC Public Forums

I have a Dell XPS 8930 PC with two hard disks:
1) 2 TB M.2 SSD (Toshiba KXG50PNV2T04), this is the normal OS boot
2) 8 TB spinning HD (WD Ultrastar)

ReadSpeed only runs for #2.

Normal run:

Any idea why the SSD is not identified?

Thanks!

The SSD is NVMe, not AHCI. ReadSpeed only identifies AHCI and IDE drives at the moment.

 

[ChuckM]

My understanding is that SpinRite 6.1 will support NVMe SSDs up to 2.2 TB, although with limited performance. Will there be an update to the ReadSpeed utility as a POC of this capability?

Thanks!

 

[AlanD]

It will only support NVMe drives through the BIOS. ReadSpeed is testing Steve's new direct drivers which bypass the BIOS and talk directly to AHCI and IDE drives. NVMe and USB drives under 2.2TB will only work at the slower speeds through the BIOS.

 

[AlanD]

If you read the latest SpinRite Development Road map, which is here https://www.grc.com/miscfiles/GRC-Development-Roadmap.pdf , it explains it all.

Hey @ChuckM, sorry for the confusion. As Alan said, the ReadSpeed benchmark was created only to validate the operation of our new IDE/ATA/SATA/AHCI drivers. So it is not meant to show what SpinRite will see. As you noted, SpinRite WILL run on all of our drives, just not super-speedy on the NVMe drive. SRv7.x will fix that!
