Unless I'm mistaken, 300MB/sec is much faster than 480Mb/sec of USB 2.0. But your point remains, even at maximum speed transfering 2TB at that speed would be unpleasant.]]>Dec 2nd 2009 3:06AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/This is SD cards, not USB drives, and this speed might be useful for high-end cameras that internally write their data fast, like commercial HD video.
Of course reading it into the computer might be an issue and need some sort of lightpeak or SATA6 SD-card reader.

The 300MB transfer is probably an aspiration rather than reality - but so, certainly, is the 2TB, so it balances out...]]>Dec 2nd 2009 8:13AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/Due you aren't transferring it ALL AT ONCE. Its meant for portable devices not 1 TB pr0n collection backups.]]>Dec 2nd 2009 9:24AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/
USB 2.0 Speed: 480Mbits/s = 60Mbytes/s
SD 4.0 Speed: 2400Mbits/s = 300Mbytes/s

So its is 5 times faster than USB 2.0. It also means that 1TB will transfer in less than 4 seconds. ]]>Dec 2nd 2009 10:11AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/
You need to check your math. It won't take under 4 seconds. It will take less than 4,000 seconds. 3,413 seconds to be precise. That is 57 minutes.

Also, no one has noticed that it is 2Tb (not bytes). This means it's 250GB. So it will only take 853 seconds or 14 minutes to transfer everything. This seems very reasonable to me.]]>Dec 2nd 2009 11:06AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/
Yep you're, right. It wasn't math error, b/c I was thinking 4000 seconds in my head, more likely a brain->typing hand communication error. Either way, that is way faster than USB 2.0. ]]>Dec 2nd 2009 11:32AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/Dec 2nd 2009 2:46AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/Dec 2nd 2009 8:52AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/Dec 2nd 2009 11:44AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/
Agree with Dante. Even filling up my 16gb micro sdhc takes an hour +. Good to see that they have worked on increasing the speeds but as capacity of the cards and our add levels grow it will need to be a whole lot faster than this to not be frustrating.]]>Dec 2nd 2009 3:02AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/Dec 2nd 2009 4:04AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/Dec 2nd 2009 5:09AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/
Serial data arrives one bit at a time, so there is no settling time. The upper bound on serial data is the switching time. Faster electronic / optical interfaces directly translate to faster serial transfer.]]>Dec 2nd 2009 8:27AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/Dec 2nd 2009 12:02PMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/Look at CompactFlash, still big due to having an onboard controller and using a standard bus (IDE/PATA).]]>Dec 2nd 2009 5:44AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/The file size limitation of FAT is an annoyance.]]>Dec 2nd 2009 9:25AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/Closed-source software developers will eventually have to adapt to it, rather than open-source software developers not even getting a chance to adapt to it.]]>Dec 2nd 2009 11:40AMhttp://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/http://www.engadget.com/2009/12/02/next-generation-sd-specification-comes-to-light-300mbps-just-ar/I prefer the linux FS but the problem is getting existing operating systems to support native read and write for it.
