45MB/s is as fast as any hard drive you’re likely to find in a UMPC so folks, consider this Transcend 300x card very fast indeed! It’s CF 4.1 compliant [PDF] and it’s got ECC (error correction) support. In something like the Everun S6S with the supplied CF card adaptor, it would be perfect and probably a lot faster than the internal on-board flash. At 229 Euro for the 16Gb version though, its certainly not a cheap option but I’ve found the 8GB version online for 80 Euros so I’ve gone ahead and ordered one. I’m looking forward to testing it with the Everun to see how fast it is and am even thinking of running an OS on it in the Q1 Ultra. Elmstrom, a member on the portal here, has already tried a similar project with a similar card and he reports "A lot more responsive system." After a bit of research, it’s clear that the Transcend CF cards up to 266x have wear-leveling support  which is very important if you want to use it as an OS drive otherwise otherwise swap/pagefiles can burn a ‘hole’ in the card very quickly. Unfortunately, there’s no data sheet yet for the 300x card so its possible that it doesn’t actually have wear-levelling. There’s only one way to find out!
