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 '14 SSDrivePro]

The 128GB 840 Pro is a rock solid performer. On release, nearly a year and a half ago, the Pro smashed several speed records. Today, with sequential read/write speeds of 519/438 MBps, the Pro is still one of the fastest SSDs available. One of the Pro's top competitors is Samsungs own, newer 840 Evo. Looking at a raw synthetic speed comparison of the 128GB Pro and Evo is a little misleading. On the face of it the Pro only has a marginal lead over the Evo. This due to the fact that the Evo can only maintain its burst write speed for transfers of up to 3GB, the size of its SLC cache. The Pro on the other hand can sustain higher throughputs indefinitely. The Pro also utilizes MLC which is rated for far more erase cycles than the TLC used in the Evo. Server IO is often continuous and would quickly exhaust the 3GB cache on the Evo but for typical consumer use the Evo will remain within the SLC cache most of the time. [Feb '14 SSDrivePro]
