What is a good write speed for a hard drive?
A typical 7200 RPM HDD will deliver a read/write speed of 80-160MB/s. On the other hand, a typical SSD will deliver read/write speed of between 200 MB/s to 550 MB/s. As noted above, an SSD can deliver a much better read/write speed to an HDD.
What should my disk transfer rate be?
Because of how hard drives work—with rotating discs—and the way in which they store and access data, they are usually limited to a transfer rate of about 100 MBps–200 MBps. The data transfer rate of a hard drive depends on the model and the interface it uses to function (usually SATA).

How is the as SSD total score calculated?
The AS-SSD Total Score is derived from various speed measurements taken by the AS-SSD benchmarking utility. The purpose of the score is to summarize the performance characteristics of an SSD. It is calculated as follows: Total Score = SeqW*0.15 + SeqR*0.1 + 4kR*2 + 4kW + 4k64W + 4k64R*1.5 All speeds are measured in MBps .
