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.

The 120GB M500 is successor to the phenomenally successful Crucial M4. The M500 was poised to win loyal M4 customers but as it turns out the new M500 is worse for typical consumer use than the now nearly three years old M4. There are some cosmetic performance improvements over the M4 but they are purely synthetic. For example, deep queue speeds are significantly improved and the newer M500 handles mixed IO far better. Consumers require decent sequential read/write speeds which average 435/185 MB/s on the M4 vs 395/134 MB/s on the M500! Other manufacturers have come leaps and bounds over the last three years which has raised the performance bar is several notches. In today's market the new M500 simply cannot compete on performance, it doesn't even come close to the likes of the Samsung Evo or OCZ Vector 150. The M500, however, is one of the cheapest mainstream SSDs available at this time but it's easy to justify spending just a little more for a lot more performance. [Feb '14SSDrivePro]
