I have purchased a new HDD for my backups. Before entrusting the device with the job of keeping my data safe I want to make sure that it is in good condition. The drive is a new internal 3.5 inch SATA drive.
I started a destructive write test with badblocks using the following command.
(Important: DON'T just copy paste the following command it will erase all data on your disk)
# badblocks -wsv -t random /dev/<device>
After ~ 1:30h the badblocks run has reached 0.36% completion. iotop reports average writespeeds between 1.6 and 2.5 MB/s which is about 1% of the write speed the drive should actually be capable of. The IO load reported by iotop is 99.9% though.
Is there something odd going on or is it really common for badblocks to perform that slow?
