    Does anyone know the speed of the SD card reader on Vaio TT? I am planning to run the Windows 7 from the HDD; and run Ubuntu from the flash card that I will be putting on that reader, however, I could not decide which card to buy. I want to buy the fastest card available, but on the other hand I do not want to waste my money by buying some card that is way too fast for my reader.

    I have no idea what the max speed is on your reader. If your card is sdhc and you format it for NFTS you will will be able to get the best speed out of the reader. I have a class 6 in mine to handle a program that uses paging. In general I would not buy a card larger than you need either.

    It's not wonderful. I've just written a 3GB ISO file to a 4GB class 6 Kingston SDHC card on a TT(27GDX), and the transfer speed averaged a little over 6.1MB/sec.

    Going from the SD card back to the HDD gave approx. 9.1MB/sec.

    Thanks for the link - quite interesting reading. A couple of things come to mind with this - (1) it doesn't look like it would fit inside a TT. (2) Is it's real-life performance that much of a world away from the latest generation Flash SSD's eg the Intel X series?

    That is correct it will not fit in the TT or any other vaio. It is huge because it uses sticks of ram that are the fastest speed. There is currently not an ssdd or ss anything that comes anywhere near the speed of ram. Do you have a link to the intel x series.

    Further to my hunch re the real-world performance of the HyperDrive vs SSD, the following pulled from a DV Nation forum:

    "I've found a detailed 12 page review of the HyperDrive5 (aka Acard ANS-9010) on the Tech Report web site.

    The review includes a whole raft of benchmarks and compares the HyperDrive to various other hard drives including SSDs like Intel's X25-M and X25-E Extreme. The benchmarks bear out my (unscientific) evaluation of the unit, in that it's performance is ok, but pretty unremarkable.

    Thanks for the link - there is reference in the thread to enabling caching on the Memory Stick to increase performance. I tried the same with my SD card and the increase in performance was quite significant. I've now dedicated it to ready-boost as an experiment.
