The Sandisk Extreme was once a good choice of SSD thanks to its extremely (pun intended) competitive price. In terms of performance the Extreme would of course obliterate any regular hard drive but at 16 months old the Extreme can no longer compete with more recent SSDs. In terms of typical consumer workloads the Sandisk delivers below average performance and is even less capable when it comes to server workloads scoring a total of just 761 on the AS-SSD benchmark. The weaknesses in performance are a consequence of the now dated Sandforce SF2281VB1 controller which delivers sub-optimal compressible transfer rates. The best thing the Sandisk Extreme has going for it is that its successor, the Extreme II, was just recently released. [Jun '13SSDrivePro]
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]
