content: My main problem with this Compact Flash is that the "real-time" performance is very slow. I bought it a year ago for my 5-Megapixel camera, and it makes me wait a long time before I can take my next photo. This gets frustrating when you miss good photo opportunities.Then, I read this article which reviews Compact Flash cards, and I realized that this particular SanDisk product line is inferior.The review at DP Review says this Sandisk writes at 6x (where 'x' = 150 KB/sec). I since then, have purchased a 512MB Transcend compact flash which claims to Write at 25x. My camera works much faster now. I have borrowed my friend's IBM Microdrive and that is really fast too.
