#96 hdparm -t does not display accurate bandwidth for fast SSD

[Laurent Bonnaud]

Hi,
my system has a fast SSD with read speed above 7GB/s.
However, hdparm -t is not able to measure this speed accurately:

# hdparm -t /dev/nvme0n1

/dev/nvme0n1:
 Timing buffered disk reads: 7362 MB in  3.00 seconds = 2453.67 MB/sec

Other benchmark software, such as gnome-disks, display a read speed above 7GB/s.
