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. ^{[Jun '14 SSDrivePro]}

The Mushkin Chronos and Chronos Deluxe are both Sandforce 2881 based SSDs from Mushkin. The only difference between the two is their NAND Flash: Intel asynchronous 25Nm for the Chronos vs Toshiba 32Nm Toggle Mode for the Deluxe. The 32Nm Toggle NAND supports far higher write speeds as can be seen from this direct performance comparison of the two drives. Overall the Chronos Deluxe performs slightly above expectations for a Sandforce SF2281 drive, it has reasonable read speeds but still struggles when faced with writing incompressible data. With an effective (real world) speed of 347 MB/s the Chronos Deluxe lags the group leaders by 50% and as such there are far better drives, such as the Samsung Evo, available in today's market. ^{[Jan '14 SSDrivePro]}
