So far we have only discussed read speeds. let us next have a look at write speeds. For this, we will be using dd. The safest way to do this, is to first create a filesystem (outside of the scope of this article – to make it easier . After however long you specify--30 seconds in the above test--the test results will be printed to the Command Prompt and you can view them. Consult the results and you'll see the average MB/s the drive reached during the test--how many write operations were performed a second, how many read operations were performed a second, and the total amount of .HDDScan is a Free test tool for hard disk drives, USB flash, RAID volumes and SSD drives. The utility can check your disk for bad blocks in various test modes (reading, verification, erasing), predicting disk degradation before you have to call data recovery service.

hdparm is a Linux command line utility that allows to set and view hardware parameters of hard disk drives. And it can also be used as a simple benchmarking tool that allows to quickly find out the READ speed of a disk. hdparm is available from standard repositories on the most Linux distributions. Install hdparm depending on your Linux . 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 .
CrystalDiskMark is a simple disk benchmark software that measures sequential and random performance with various modes and language support.
It also is a preventing method for hard disk catastrophes. I strongly suggest risking on buying a fully tested product with a good background, than losing your so valuable information. Share. . Test environment: . You are on Linux but you can attach your HDD to a friend's computer running Windows. 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 Fio which stands for Flexible I/O Tester is a free and open source disk I/O tool used both for benchmark and stress/hardware verification developed by Jens Axboe.. It has support for 19 different types of I/O engines (sync, mmap, libaio, posixaio, SG v3, splice, null, network, syslet, guasi, solarisaio, and more), I/O priorities (for newer Linux kernels), rate I/O, forked or .
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. $ stress --vm N. Sample Output: The top command output shows the high VIRT and RES memory. Read more at Beginners guide on linux memory management and How to check memory usage per process in Linux. 4. Increase Disk I/O Load. You can increase I/O load using the -i or --io option. $ stress -i N. OR $ stress --io N. Sample Output:

As far as stress/performance test, there are a couple. E2fsck has some options to do it also for ext2 and ext3 partitions which essentially runs badblocks in the background. Below I listed a few stess tests I have ran across in my linux usage.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
How to check the performance of a hard drive (Either via terminal or GUI). The write speed. The read speed. Cache size and speed. Random speed. Unfortunately, the actual workload of a typical disk doesn't look like that—and that "simple speed test" doesn't reproduce a lot of the bottlenecks that slow down disk access in real-world systems.
stress is a simple yet powerful tool designed to impose a configurable amount of CPU, memory, I/O, or disk stress on a Linux system. By simulating heavy workloads, allows administrators to observe how the system responds under pressure. . Linux Hard Drive Stress Test. 4. To run 8 CPU stressors, 4 I/O stressors, and 1 virtual memory stressor . To stress test the HDD (hard disk drive) of a Linux system, you can use the stress command with the -d option followed by the number of workers you want to spawn, and --hdd-bytes option to specify the amount of data each worker should write. For example, the following command will spawn 2 workers to stress test the HDD, with each worker writing .
