Keep in mind that all Solid State Disks are NOT the same. I made the same mistake and purchased a Transcend 8 GB model. My 8 GB model used old technology and not the newer, faster flash. It was noticeably slower than traditional spinning disks.
Just check some of the published specs and benchmarks and compare: http://www.anandtech.com/storage/showdoc.aspx?i=3133&p=5 http://www.transcendusa.com/support/dlcenter/datasheet/SSD25S%20Datasheet%20v1.03.pdf (look at page 3 of that pdf) More reading from a vendor: http://www.dvnation.com/ssdfaq.html John On Tue, Apr 29, 2008 at 09:35:15AM -0400, Morris, Roy wrote: > I have been reading around the archives a bit and found a few > references to using 4.3 to get the full performance out of a > Transcend SSD but my results are showing that the drive is > slower on all fronts.
