Hi all, Is there any way to find out the type of the connected USB disk (Hard disk/SDD)? AFAIK there is a significant performance difference in Harddisk/SDD devices. Previously i though that the rotational flag in the sysfs will distinguish them but it is same for both the types #cat /sys/block/sda/queue/rotational 1 for both flash & HDD Is there any way to distinguish the USB Harddisk or SDD drives ? Thanks & Regards, Manish
