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 '14SSDrivePro]
The Intel 330 is just under two years old and sports a Sandforce 2281 controller coupled with Intel's own 25nm MLC NAND. This combination typically produces a performance profile that struggles with incompressible data and favours reading over writing. With peak and average sequential read/write speeds of 514/138 and 414/122 the Intel 330 is unable to compete in today's market and falls over 50% short of the group leaders which manage peak sequential read/write speeds in the 500/300 MB/s region. Small file 4K peak and average speeds are better and clocked in at 32/89 and 24/63 MB/s which is 10% below the group leaders. Overall the 330 has an effective speed of 370 MB/s which makes it one of the slowest 128GB SSDs I have seen to date. [Feb '14SSDrivePro]
