SanDisk SDHC UHS-I cards are so Extreme they went Pro
Let's get this out of the way right up front: Sandisk's new UHS-I SDHC cards are fast but not that fast. So for all the talk of "extreme" and "pro" just remember that the claimed 45MB/s read and write performance pales in comparison to Toshiba's own UHS-I cards announced back in September with staggering 95MB/s read and 80MB/s write speeds. Still, they're fast enough to capture HD video from the latest DSLRs and certainly faster than anything touting a Class 10 SDXC rating. Now for the best part, gadget masochists, they'll range in 8GB to 32GB capacities with retail pricing set somewhere between $109.99 to $349.99. Just be sure your camera supports UHS-I before making the plunge, ok?
Toshiba fulfills your need for speed with UHS-I SDHC and microSDHC cards
Panasonic must be mighty annoyed right about now, because Toshiba's seemingly got it trumped -- when the first batch of lightning-quick UHS-I cards ship in November, Toshiba's chips will be faster and larger on day one. As you can no doubt see immediately above, the latter company's fielding full-size SDHC UHS-I cards at up to 32GB that promise maximum read and write times of 95MB/s and 80MB/s respectively, not to mention tiny microSDHC units that still manage a very respectable 40MB/s and 20MB/s. As usual, these numbers are fast and loose, so don't be surprised if you get a good bit less in practice, but you should be able to rely on well above the quoted minimum transfer rate of 10MB/s. No ludicrous early-adopter memory prices quite yet, but we imagine your ego will write the necessary checks as soon Toshiba takes care of that. PR after the break.
SD cards branded with an upper-case 'I' are faster, yo
Since they're theoretically capable of 300 megabyte per second transfer rates, we knew SDXC cards wouldn't stay slow forever. How will we separate wheat from chaff when faster models do appear, though? You're looking at it. This week, the SD Association unveiled the UHS-I specification for SDXC and SDHC cards capable of transferring data at up to 104 megabytes per second -- reportedly fast enough to record HD videos in real time. Why the association chose the phrasing "up to" is a little iffy, as we thought the point of such specifications was quality control, but considering how many Class 4 and Class 6 SD cards we've tossed that didn't match up to spec, we suppose we'll make do with a ballpark estimate... until the inevitable UHS-II makes the rounds. PR after the break.
