Answer 2

What is your application? It is hard to make a suggestion, because different types have different strengths. Here are some of the most common types:

CompactFlash (CF) - strength: very sturdy, because thick, high storage (up to 8 Gb now), fairly cheap, because not optimized for physical size. Downside: fairly bulky. Most common use: many digital camera types. I personally prefer this for sturdiness.

Secure Digital (SD) - strength: small, almost as much storage as CF for similar cost. Downside: very small form factor makes it easier to loose and break. Very wide usage.

Multimedia and xD cards: very small form factor. Downside: storage capacity is limited, size makes it easy to loose.

SmartMedia: very thin, Downsides: outdated type, does not carry any electronics. very thin, breaks more easily, limited storage capacity

Memory Stick: Sony-proprietary format. Downsides: Sony proprietary, works mostly on Sony products, capacity lags behind CF (currently 4 Gb), quite bulky, very long form factor.

Here is a good site to shop for and see the formats:

Search around for "flash card comparison" to find many sites, some specializing in specific applications (e.g., digi cam write speed). Once you know your application, see if write speed makes a difference. There is a tremendous difference in digi cam performance based on write speed. I just recently purchased Transcend cards, both CF and SD, which are much more reasonably priced than the top brands but work just as well.

Answer 3

there are too many companies to count, staples, sears, then there is swissbit, sandisk, q mem, the list goes on. I use a swissbit (runs about $350 for a gig), it comes with a program that allows you to set a password, but most do nowadays.

under each brand there are different sizes: 128, 256, 512, 1 gig, 2 gigs, 3, gigs, 4 gigs, and (as far as I know) the largest out there is 8 gigs.

if your just looking to save documents for school, a 256 will do just fine. if your looknig to save programs, i'd go with a gig or more.

go to the website i listed, they have some good deals.
