Pros: As a 2GB SD card, it's non-HC (high capacity) for maximum backward compatibility--nearly all SD readers will accept it. But many SD readers will NOT read SDHC or microSDHC cards (like 4GB microSDs). So, if you have a microSDHC card, pop it in this adapter and use the USB connector--presto, it works as an HC adapter, even on an older computer. I bought a 4GB card for my phone, and use this card as an adapter to get files onto it.

Cons: For the first few insertions, my computer seemed reluctant to read it, but things got better (now that's rare!) and have had dozens of uneventful insertions since then.

Overall Review: I love being able to carry this in my wallet. I taped two business cards together on two sides, leaving the other 2 open. This creates a sort of envelope for the flash card. I insert the card/envelope into a compartment in my wallet, and once in, the flash card cannot fall out. I have the Portable Apps suite installed, and use Windows briefcase to keep files synched to my home PC. I keep a to-do list, and all my passwords in KeyPass (with the file synched via briefcase), among many other things. I also have a TrueCrypt volume for really sensitive stuff. And still have tons of space left over.

Pros: Reliable, fairly priced, reasonably quiet. Works well in leading NAS devices.

Cons: None that I'm aware of

Overall Review: I've had 3 running happily in my Infrant ReadyNAS NV+ since summer 2007, in an "XRAID" array (similar to RAID 5). I held off on adding a 4th drive because the NAS firmware imposed a 2TB upper limit on volume size and I would have left some capacity "on the table." (Not much, though--actual formatted capacity is below 700GB, so with 4 x 750GB drives, and given the "overhead" of the RAID array, only 40GB gets left behind). New firnmware upgrade (RAIDiator 4.0) permits the 2TB ceiling to be lifted (by running a special patch). Good job, Infrant/Netgear!
