Using an SDHC card instead of a flash drive (working, hardware, memory)

[EscapeCalifornia]

I keep a bunch of applications, utilities, and updates, on a flash drive I carry with me for working on people's PCs out in the field. I carry my anti-malware tools on a CD-R that I use when I know the PC is infected. That way, I avoid infecting my flash drive and transmitting it to other computers I work on. Of course I'd like to just keep everything on one flash device but the risk of infecting it is too high.

So what about using an SDHC card and a compact USB adapter instead of a USB drive? SD cards have a write protect slider but I don't know how much protection that actually offers. Could malware still write to the card or does the switch prevent writing at a hardware level? Would you expect a card reader to have more compatibility/drivers issues than a USB flash drive?

I use a USB flash drive that has a write protect switch for just the reason you state, to prevent my clients from infecting it, the switch prevents any writing to the drive, it cannot be bypassed.

What brand is it? I've looked for write-protectable flash drives without success.

Not sure as the brand name has worn off it, newegg has a few though.
