SanDisk and Seagate shipping big ones
SD card and SATA hard drive
SanDisk and Seagate are shipping their largest ever storage SD cards and SATA drives respectively. Tomorrow they'll ship even larger ones.
SanDisk can deliver a 64GB Ultra SDXC memory card, SDXC being the successor to the SDHC card format. You can put more than a day's worth of high-def video on the card, at 9Mbits/s speed, and transfer them from digital recorder to PC. Its read speed is up to 15MB/sec. SanDisk says it has an exFAT - does this mean thin? - filesystem suited to long-duration video recording and the SD 3.0 format can support cards with a 2TB capacity.
Not many cameras support this format yet but more will be coming, from Canon for example.
Seagate is shipping a Constellation ES disk drive with the SD 3.0 capacity max - 2TB. It spins at 7200rpm and has either a 6Gbit/s SAS interface or the widely-used 3Gbit/s SATA one. We first heard about this 4-platter, nearline enterprise drive in November last year.
The company also has a desktop Barracuda XT rated at 2TB, 7200rpm and 6Gbit/s SAS. Western Digital has its 2TB Caviar Black with the 3Gbit/s SATA interface and the RE4-GP ditto product covering pretty much the same markets as Seagate. Hitachi GST mentioned a 2TB, 4-platter UltraStar in August last year; it's probably still sampling, while Samsung has a 2TB EcoGreen. That wraps up the 3.5-inch 2TB drive suppliers. Seagate's Constellation has the 6gig SAS lead, for now.
SanDisk's new SDXC card costs around $350 (£259.99) - it's not cheap. Seagate's Constellation ES comes in 500GB, 1TB and 2TB variants, and Span lists the 2TB model at $382, SATA gigabytes costing a whole less than SDXC ones. ®
Class 4? WTF!
a lousy 15MB/s for a 64GB device ... pffft!
Wake me up when they come out with a Class 10 version.
They were probably thinking of Windows.
They probably recomended exFAT so it can be read by a Windows machine without installing drivers.
That said, surely most non-technical people who buy cameras and the like install the software from a CDROM so EXT2 (or whatever) drivers could be included on this?
SDXC with SD3.0 doesn't quite cut it
So, this is a bit like the first SDHC cards that came out before the standard had stabilized. I'll wait a couple of months for the SD4.0 standard to be ratified.
And, -tim, the SDXC has a very specific raison d'etre - namely that it is physically compatible with the SD/SDHC (and to a large extent all the flavours of MMC).
Oh, you're not forced to use exFAT, it's still just a block device, so in theory you can use ext4 or whatever you want on it. It's still a shame that the SD consortium recommend a proprietary file system.
