HD Tune is one of the most popular and widely-used benchmarking tools for measuring the performance of storage drives. General read and write performance of the Transcend SATA III SSD720 was good and was amongst the quickest drives. Random access times was also not too shabby, though it recorded a slightly higher than average random read access time of 1.3ms. Again, random read speeds were a bit lower at 399MB/s, noticeably lower than the other SandForce drives which achieved above 450MB/s. However, it redeemed itself with very high random write speeds of 442MB/s.
