In can take a lot of time to complete: as stated .
The badblocks utility, part of the e2fs suite of tools, is good way to test a drive. It is probably more through than the on-drive smart diagnostics, when run in write mode. The down side of write mode is that it destroys any existing data — although this can be an advantage if you wish to throughly remove all data from a drive. For performance results higher numbers are better, for CPU usage lower are better. It test more than 2Gb of storage on 32-bit machines, and tests for file creat(), stat(), unlink() operations. Install bonnie++ for Linux hard drive benchmark test. Download from official web site or use apt-get to install bonnie++: # apt-get install bonnie++ Hard drives, though, are typically used for large sequential reads and writes, so a random IO test doesn't match the use case here. If you want to change the test type, you can pass in a different argument for --readwrite. fio supports a lot of different tests: Sequential Read: seqread Sequential Write:seqwrite Random Read: randread Random Write: randwrite When the benchmark tool is complete, Gnome Disk Utility will create a full readout of your hard drive.

It was not clicking loudly though, like a drive that has already gone bad. After tightening the connections to the hard drive, it stopped clicking and I was able to access the data again. Things get a little extra complicated here, because we're mixing units—notice the big B in MB/sec, and the small b in Gbps. That's the difference between bytes and bits.
Is there any simple command (or tool) to test the speed (MB/sec) of disk access? I've found hdparm but It look it only works for local disk. I need to evaluate the speed of remote NFS-mounted disk. Thanks in advance!
In 2005, Canadian Mark Lord developed the small hdparm utility to test Linux drivers for IDE hard drives. Since then, the program has developed into a valuable tool for diagnosis and tuning of hard drives. For example, it tests the speed of hard drives and solid state disks, puts devices to sleep, and turns the energy-saving mode on or off.
