GREAT [Posted on 2007-12-23]
This card is excellent. Great purchase if you're a beginner and buying a new D-SLR.

Very Fast [Posted on 2008-01-12]
This product was purchased along with a Canon 40D DSLR. This combination has proven to be extremely fast. I notice no delays when shooting with this card. This by itself is probably of little relevance though as the camera is likely the slower of the two pieces of hardware (Canon doesn't spec it's transfer rates). It does make a huge difference however when uploading to the computer for backup/editing purposes. This memory flies when used with the SanDisk Firewire card reader!!!

Cons: Very expensive considering even the cost of the last generation of SanDisk.

Very fast card. Worth the money. [Posted on 2008-01-13]
I already had the Extreme III - 2GB. I wanted another one for my Canon XTi. I went ahead and got this Extreme IV. Have not been disappointed. Transfers from card to DEsktop is also very fast.

Yeah baby! This is what I'm talking about when I say "Fast!" [Posted on 2008-02-05]
Wow, this is fast. I shot a bike race yesterday and this was just great. Filed the almost the entire card and never a hiccup. A lot of rapid shooting (3fps) and there was never a slow down in writing to the card, even in RAW. The download to the computer was much faster than anything I've used in the past. Just a few minutes to download 2GB!

I've been using this for about a month now and couldn't be happier. Not a single hiccup, burp or fart. Be aware that there is no arrow showing which side is the top, unlike most CF cards. So, if it's not going in, don't force it cuz it's likely upside down.

A newly formatted card holds 200 RAW images on my Rebel XTi and 442 hi-res JPEGs. Make sure you get a fast card reader--it will make a big difference.

fat 32 only [Posted on 2008-02-15]
i had a persistent i/o error when trying to write to it on my computer (try drag and droping a file to it). i purchase it with the iv reader as a package thru amazon. turns out it has to be formated using fat32 (32 bit file allocation table in MS windows) which has a lot of overhead so you don't get 1.9 mb usable. anyway sandisk tech support was helpful and they spoke california english and i did't spend all day on hold. i don't know if this problem (or requirement) is a function of the 1394 port or a sandisk requirement. in any case it would have been nice to know the downside details before purchase.

so if you want to write to it on your pc, format it with the fat32 format on your pc before putting it in your camera.
