I have a P4600 2TB NVMe SSD. Right after I used Intel SSD toolbox to secure erase it, fio reports 4kB random read at 809K IOPS. sudo fio --name=dummy --size=10G --filename=/dev/nvme0n1 --ioengine=libaio --direct=1 --rw=randread -bs=4k** --iodepth=64...

I have a P4600 SSD in my Ubuntu PC. It went dead just about 1 hour ago, as I can't perform any read/write. I notice the LEDs are in solid RED and solid AMBER. I can't find product spec for P4600. But for P3600, solid RED means it's in "disable logica...

I understand that the write perform will drop as the SSD fills up. But I am doing random read only in this case.

Hi,Thanks for the quick response and the great links.No, I was not complaining about the performance itself. I was just trying to understand why the IOPS drops.I was thinking that, right after secure erase the SSD, FTL table is also erased. This tabl...

I tried the SSD in 3 different PCs and it shows issues in all of them.Ubuntu 17.10: lspci shows the device correctly. But can't read/write. LEDs in solid red and amber.Windows 8 and Windows 10: Device Manager shows it's a Standard NVM Express Control...

Why does "fio write" change the performance of "fio read"

How to get out of "disable logical mode"?

Does Intel SSD 750 support NVMe 1.0 or 1,2.1?
