Atto is a simple but popular synthetic benchmark for testing the maximum theoretical speed of storage devices. In this test, the read speed of the Crucial SSD crushed the respective performance of two popular mechanical drives, but the WD AAKS drive managed to take the upper hand with its outstanding write speed.

HD Tach is a benchmark able to show the sequential read speed across the entire capacity range. As mechanical drives become slower as the data is being moved towards the edge of the platters, in this test they start with their maximum sequential read speed and end with the minimum. This is not the case for the Crucial SSD drive though as it has no rotating platters or other moving parts and so it can sustain its maximum speed across its entire data range.

HD Tach is also able to record the random access time of the drives, which is where the true advantage of the SSD drive reveals itself. The Crucial SSD drive has a random access time of 0.4ms, while most mechanical 7200RPM drives hardly reach 12ms, which is around 30 times slower.

In order to verify the results we achieved from HD Tach we used another similar benchmark, HD Tune Pro, which also features a better random access time test. HD Tune Pro gave us similar results with HD Tach on both the sequential read and random access speeds. It is noteworthy to mention that the access time the mechanical drives need in order to access data increases as their data moves towards the edge of the platter, while the SSD drive has a steady and miniscule access speed across the entire data range.

Sandra is one of the most popular synthetic benchmarking suites. Here the Crucial SSD drive maintains a constant speed ratio of 128MB/s, while the mechanical drives fall far behind. Matter of fact the speed of the Seagate 7200.10 drive is less than half than that of the Crucial SSD drive. Unfortunately this benchmark cannot identify random access times below 1ms and all devices with a <1ms random access speed are simply rated as 1ms.
