I can't really see how they're (and by they I mean all SSD manufacturers) going to fix the performance degradation issue. It's a problem that is inherent to the flash technology. The problem is that of data pages. Every time you want to change even 1 bit you have to read the page that bit is stored in, erase that page and then write it back. At first, when the disk is fresh and unused data can simply be written to the disk. However, as more and more of the disk's space gets filled you'll have to perform the routine mentioned above. A way to alleviate the problem a bit is to have a huge DRAM cache on the disk. Intel's X25 series has 16MB on-board and I believe the Vertex has 64MB, which is the main, if not the only, reason it's faster than the X25 at writing. Oh, and by the way, any SSD using the JMicron JMF602 controller is a pure hands-off product. Avoid at all cost! They'll never run fast, even if a "new" design is advertised. They also consume way too much power.
