TESTA A measure of how well a Hard Drive responds to typical consumer access patterns. Toshiba P300 ≈ 100%.
There are a multitude of different speeds associated with any type of storage device (sequential, random, deep queue). When estimating how well a device will perform, it is essential to make reasonable assumptions about the type of access patterns that the device will be used for. Most consumer hard drives are used as a combination of storage and system drive. Following massive reductions in the price of RAM over recent years typical desktop computers now have enough RAM to cache a reasonable proportion of system files. The real world hard drive speed is weighted as 37.5% sequential read, 37.5% sequential write, 12.5% 4K read and 12.5% 4k write. This set of weights favours large files and is therefore slightly skewed towards storage drives rather than system drives (an SSD should normally be used for system drives).
