SAS drives are faster, capable of 600MBps and even 1500MBps transfer speeds in some cases. From there they grade up to between 3000 Mbps and 375 MBps to 6000 Mbps and 750 MBps for SATA. Some are as slow as 1200 Mbps and 150 MBps.

Raw speed: Some hard drives are designed to be faster than others.

In some scenarios one or other may have more weight when it comes to product selection. MBps specifies how much of a file is downloaded/uploaded per second. The former specifies internet connection speeds. Watch out then for Mbps (Megabits per second) and MBps (Megabytes per second).

MB v Mb: There is often some confusion between megabits (Mb) and Megabytes (MB).

Hard Drive Benchmarking Tools Selection TipsĪlthough it might seem simple to test the performance of a hard drive there are a number of factors to consider.

Top Hard Drive Benchmark Tools and Vendors.

Hard Drive Benchmarking Tools Selection Tips.

The last thing you want is a drive that can’t keep up with the bandwidth, latency, and communication pace of the rest of the hardware. It is important to pick components with matching performance categories. These can be useful when debugging device performance, in drive selection, and in many other ways. Accordingly, there are a number of hard drive benchmarking tools out there to help you test your drives.

Where they tend to differentiate themselves, therefore, is in terms of performance and especially speed. The point is that hard drives have largely stood the reliability test of time.

The good folks at Western Digital kindly agreed to let their forensic specialists try to recover my data but it was not to be. Unfortunately, it was knocked off a desk and it wouldn’t start. It was great for backup and when I moved from one device to another. I loved it and stored all my files on it. There was another incident – a very early small form factor external drive from Western Digital. In that case, all of the data was easily recoverable. When I think about the number of laptops and PCs I’ve owned and used over the past 25 years, I can only think of one failure. Hard drives have run pretty well over the years.
