If you've been following the development of the Solid State Drive, you have likely been only marginally impressed versus dazzled. It's not hard to see the potential in SSDs, but they've been held back by size, price, and for a reason we're still trying to fathom, PATA to SATA converters that typically eat a fair amount of transfer capacity.
A few firms have gotten rid of the converters, but Samsung is doing one better. They're going native SATA II and entering mass production.
"Due to the inclusion of the SATA II interface on the new refresh, transfer rates on the new 64GB SATA II SSD will increase 60 percent from SATA I versions of the same drive. Instead of the 65 MB/sec read and 45 MB/sec write speeds of the previous PATA SSD drive, the SATA II flavor will produce a maximum write speed of 120 MB/sec read and 100 MB/sec write speeds."
With improved reliability over mechanical drives and virtually no access time to speak of, this might finally be the start of SSD's big break. This leaves the only compromises we can see as overall capacity and price/GB.
