I also have an a-data 150x 2GB SD in my Nikon D40 D-SLR. Somehow they both have the same r/w speed. This one was bought some time ago. Couldnt believe the performance of this one. Lexar is absolutely Lexar. Cant be beaten.
I have 2 other mini SD cards and this Lexar seems to be the fastest as far as transfers go... otherwise, all of them seem to be pretty much the same. Little bit expensive for the brand name but makes it up with it's quality of construction.
I am a previous user of Lexar CF cards and SD cards and have always had good performance out of their products (camera, computer, etc). The MicroSD 2GB card is being used in a Garmin 60CSx GPS handheld unit, which is in itself quite amazing. I also have Kingston 2GB MicroSDs and am comparing them against the Lexar. So far the Lexar appears to be slightly faster, although I haven't had it long enough to really get a better feeling for performance. The card is used to store GPS navigation and topo maps. The special offered by Buy.com was too good to pass up, especially for a Lexar product; and I had use for one. I am confident it will become a favorite among my microSD cards.
I used a little USB holder and plugged the micro SD in to my HP Desktop. No problem transferring mp3 jpg and doc files. Moved the USB holder to a Dell Laptop, inserted the card into a PDA (Sprint Mogul), and a cell phone (Sprint Muziq). All were able to read the files. No problems.
Buy.com shipped a defective unit (naturally, unaware). I contacted Lexar for a replacement and they were very cooperative. The replacement card works well. Speed is moderate (for cell phone use). Not much else to say.
I purchased the Lexar 2GB microSD card for use in a Garmin 60CSx multi-use GPS instrument (auto/handheld). The first card arrived DOA and was promptly replaced by Lexar (good communications) and the new unit functioned perfectly. It appears to be slitghtly faster than the similar Kingston 2GB microSD card. A good product.
