At four months old, the 128GB Toshiba Q Series Pro is the newest SSD in the group test. It's always nice to see new drives pushing established speed boundaries and the Q Series Pro does exactly that. With peak and average sequential read/write speeds of 521/481 and 422/333 MB/s the Q Series Pro beats the 128GB group average peak write speed by 45% and is bested only by the Samsung Evo. A particularly impressive aspect of the Q Series Pro's performance profile is its mixed IO performance where it beats the average of the group leaders by a stunning 50% and sets new sequential/4k mixed IO records of 502/40.4 MB/s. The ability to handle concurrent read and write operations well means that the Q Series Pro will rarely pause for breath, even when faced with varying IO demands, a great server orientated trait. Overall the Q Series Pro has a very robust performance profile and is well priced making it one of the top 128GB SSDs of 2014. [Feb '14 SSDrivePro]
