Pros Reliable brand, high capacity
Cons Cheaper SD cards can be found at the same capacity
Summary I've learned to avoid generic computer parts after having so many OEM hardware glitches and failures, particularly in the realm of RAM. Granted, SD cards are flash memory, whereas most of my past woes involved DRAM modules, but you can't go wrong with SanDisk, one of the reputable flash memory manufacturers.
This is not a gadget so much as a thing that you stick in your gadget to upgrade it. That said, I'm using it inside a 6.1 megapixel digital camera that also shoots Quicktime movies, and it's doing a fine job allowing me to be a shutterbug with everything set on the highest resolution settings without worrying about capacity. Given the tiny size of SD, it and an adapter are scarcely larger than a USB keychain drive, so this card could double as one of those, but with a capacity greater than a CD--great for transferring things like 800 MB video files.
Data transfer speeds are pretty good, though I haven't done any benchmarks against other cards. I'm more happy about the fact that it does what it's supposed to do--hold a lot of data in a small package, and work right every time.
Pros great amount of memory for picts & music
Cons there are no cons what so ever
Summary the best of the best
Pros 1 gig capacity
Cons Only holds 34 (or is it 38?) tif format images
Summary As soon as I find a 2 gig card foa as cheap as I got his one, I'm going with it. But 340 jpg's at max res, it'll do for now. Fairly fast transfer to my PC from my Bonzai card reader/writer (now that's a handy li'l dude!). It works...not much else to say.
