Sandisk has gone official with its new lines of high-performance memory cards. At the top of the pack (if not at the top of the world) is the new Extreme Pro line. Available only in CompactFlash, the Extreme Pro line sports maximum write speeds of up to 90 megabytes per second (that’s 600x, for those of you used to the older terms). It’s also the not only UDMA, but it’s the newer UDMA 6 spec (which means it’s actually faster than your hard drive, very likely). As if to reinforce that these are, indeed, just for pros, they come in three sizes starting at 16 GB and working up to 64 GB.

Next up are the new “Extreme” line cards. No “III”, no “IV”, just plain old extreme. Apparently slotting above the Extreme IV line, but below the Extreme Pro line (and just-as-apparently replacing the discontinued “Ducati” line), the Extreme line comes in both CompactFlash and Secure Digital High Capacity flavors.
The CF flavors sport a jaunty 60 MB/s maximum write speed (400x), and are obviously UDMA-enabled (although since they don’t specify they’re probably the slower UDMA 5 spec). Oriented to be a bit more consumer-friendly, they come in three sizes from 8-32 GB.
And, lastly, we have the Extreme line in its SDHC flavor. Now extending up to a rather impressive 32 GB in capacity, these new SDHC’s feature 30 MB/s maximum write speed (200x), and, if Sandisk is using its classes properly, the note that it’s Class 10 should intimate that the slowest it’ll go is 10 MB/s. The SDHCs are available in four capacities.
- 4 GB Extreme SDHC
- 8 GB Extreme SDHC
- 16 GB Extreme SDHC
- 32 GB Extreme SDHC
