1 The main target of the test, virtually all testing will also involve the CPU and RAM to some extent.; 2 Light tests do not push the components very hard (in terms of power/heat limits). These tests are still useful to test how the hardware behaves in lower power levels (P states), in particular for undervolted systems. 3 Realistic tests are based on real world workloads.The output of this test on the "The Seagate Momentus 5400.6" (ST9160301AS) from the hdparm example above shows that dd can be useful to get an idea how a drive performs: # dd if=/dev/zero of=test.file bs=64M count=16 oflag=dsync 16+0 records in 16+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 20.4171 s, 52.6 MB/s

CrystalDiskMark is a simple disk benchmark software that measures sequential and random performance with various modes and language support.
For the test, we’ve set the block size to 1 megabyte, and we’ll be writing 1024 counts of such blocks. Additionally, we pass the conv=fdatasync options to the command to ensure the disk is written to the disk physically, and not in the buffer at completion. 3.2. Testing Sequential Read Speed
After 3 days of this stress testing you can go to each terminal and type CTRL+C to cancel the loops so that it stops writing/reading data to the disk. Notes: Note that I reference /dev/urandom and not /dev/random.urandom generates more data with pseudo randomness consistently whereas /dev/random is much more secure with randomness but will not generate .What should I do for a noisy disk drive?
