Just bought a 512MB CF from MS Color. Was told it just arrived and is the High Speed version. Really? Never heard about it, but took their word for it. Was told that it is 30x, but can't see the info on the box (except for a sticker saying 'high speed'). Anyone know anything about this? On the box, it says '512MB Compact Flash (R)'. Apparently I came across some posting on the web saying there are L and R (maybe other) versions. Where can I find info? If it the same as the normal Kingston CF, then why the 'High Speed' sticker? Those I bought previously did not have the 'High Speed' sticker.
