The 240GB Intel 335 Series SSD is four months older than the group leaders which average 13 months old. The hardware configuration consists of a Sandforce 2281 controller which is coupled with Intel's own 20Nm NAND flash. This particular combination is known to have relatively weak compressible write speeds, and the observed performance figures confirm this. With sequential peak and average read/write speeds of 510/234 and 367/209 MB/s the core performance profile is exactly as I would expect, very skewed in favour of reading over writing. With an overall effective speed of 434 MB/s the 335 is nearly 25% slower than the 533 MB/s group average. There are both faster and cheaper alternatives in the group test. [Feb '14SSDrivePro]
The 240GB Sandisk Extreme Pro uses the same controller and NAND as its 13 months younger predecessor, the Extreme II. Comparing the Extreme II and Extreme Pro shows that average performance has increased by 10% but peak performance remains broadly unchanged. The Pro features an improved nCache which uses an SLC buffer to cache writes prior to writing them to the slower MLC NAND. In order to benefit from this improved caching, huge amounts of data need to be written for extended periods, an unlikely consumer scenario. Comparing core performance between the Samsung 840 Evo and Extreme Pro shows that the Extreme Pro averages around 12% faster than the Evo. The Extreme Pro also has a 10 year warranty but I wonder if SATA 3 will even be around at that time. Although the Extreme Pro has a superb performance profile it's not a game changer.
