![]() ![]() This rating is the fastest speed at which data can continuously be written to a drive, often shown in Megabytes per Second (MB/s). Reading a file is always faster than writing one, so the critical speed criteria to observe is maximum sustained write speed. The larger the cache size, the better the performance. To improve performance, manufacturers include a small volatile cache to store data while waiting to be written to the drive. Mechanical drives are limited in speed, partially by physics. Common RPM rates range between 5,400 to 7,200. The faster the platters rotate, the higher the speed of the drive. ![]() Mechanical hard drives make use of “platters” inside that rotate at high speeds for data access. The longer this rating is, the more reliable your drive will be. The MTBF rating is the average time the manufacturer has observed to pass (on average) before the drive starts failing. Like all hardware, hard drives will eventually fail. Often listed in Terabytes (TB), hard drive capacity is the amount of data you can store on the drive.
