Has anyone experienced a notable difference in speed between Extreme III and Extreme IV cards? I bought some of the IV cards a couple of days ago, and was expecting to see a notable difference in save speed when shooting raw, but really can't notice much difference at all. Not without resorting to a stopwatch that is. On their website they say that the IVs were "up to" 40MB/sec. They don't seem to much better than the IIIs at 20MB/sec. I guess that "up to" is more advertising blurb than reality. Secret Squirrel >Has anyone experienced a notable difference in speed between Extreme III >and Extreme IV cards?

You just have to hold your mouth right and wait for a north wind, then you'll get that 40MB/sec. Otherwise I'm afraid you'll have to make do with 21. [But console yourself with the thought that at least the thing works. Which is a *considerable* advance on the two Exigo thumb drives I bought from Citysoft a year or so ago. They nearly caused me the loss of a week's worth of travel photos. And would have, except my inherent paranoia ensured I had also copied them to a couple of CDRs as well as leaving a copy of them all on a friend's PC at the time.] Cheers, Phred.

CF in this case, in fact I don't think they make SD in Extreme IV yet. I was using SDHC as soon as they came out then I moved up to Extreme II's then Extreme IIIs. There was a noticeable difference in frame rate with both those upgrades but none with this last one. I think that until I have a camera that makes real use of any further speed increases I'll stick to the Extreme IIIs.

Firstly, is your camera capable of those sorts of speeds? Secondly, are they genuine IV cards, or "ebay specials" (ie whatever sh.t they can get cheap and with copied IV logos stuck on it)? > Secret Squirrel >> Has anyone experienced a notable difference in speed between Extreme >> III and Extreme IV cards? [quoted text clipped - 10 lines] >> >> Secret Squirrel I use two DSLR camera systems, Canon and Nikon, plus I always carry a Panasonic FZ50 with me as a general purpose camera. One of the many advantages of being a girl is the expectation that you will carry half your possessions with you in a large shoulder bag. I use a nice leather video kitbag as a carryall. Even I don't know what is lurking in the very bottom of that bag. The Pansonic is SD only, not Compact Flash like the others, but using it with SanDisk Extreme III SDs it seems as fast in practice at saving a 20+ meg raw file as the others with the SanDisk Extreme IV CompactDisk cards. And yes, they are genuine SanDisk Extreme cards, purchased through a major photographic supplier. I went back to the store yesterday and they tell me that in their own tests the card doesn't improve camera performance by very much, but it transfers data much more quickly. In future I will be sticking to the Extreme IIIs, the extra cost isn't justifiable. Secret Squirrel SignatureIngrid Rose clandestin.ecureuil(insert missing symbol here)gmail.com |
