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 '14SSDrivePro]
The 128GB Vertex 450 has a reasonable but somewhat unusual performance profile. The main weakness is its sequential write speed which is only 282 MB/s peak. This implies that the 128GB version has fewer NAND modules than both its larger 256GB sibling and several other leading 128GB models. Other SSDs, including some 128GB models can consistently achieve sequential write speeds in the 500 MB/s range. A handicap of this magnitude on a key performance metric would normally relegate an SSD to the lower divisions but the Vertex 450 offsets its poor sequential write speed with a record breaking 4K write speed of 158 MB/s which is the highest I have ever seen on any SSD. Overall the Vertex 450 has an average, but quirky, performance profile and is reasonably priced however there are both faster and cheaper alternatives available on the SSD leaderboard.
