Thread: USB 3.0: What's the difference ?

USB 3.0, the next major revision of the Universal Serial Bus, promises to provide much higher data transfer speeds than its predecessor, the USB 2.0 . USB 3.0 also features some power saving methods.

USB 3.0 can provide up to 4.8Gbps transfer speeds, thats 10x that of USB 2.0(480mbps). Well, these are just theoretical numbers, but even at half the theoretical bandwidth, its still a hell lot faster.

But, you we need such high speeds ?? Well, yes !! With more demand of High Definition (HD, bluray) content and high resolution pictures, we would surely need that extra speed.

So, is it the end on USB 2.0 ? No, not at all. It will take a few more years for it to phase out, as not all applications need these speeds. The initial costs are always going to be high and this will be a slow phase. Good thing is, your USB 2.0 peripherals will work even in USB 3.0 slots.

There are a few new motherboards that support USB 3.0 and a few flash drives that are already in the market. Both have a tad high price, but not too bad.

Bottom line: It will still take USB 3.0 some years to be implemented properly and become mainstream, but for now, USB 2.0 is enough.

Good one Rajan. Thanks for sharing

hmmm........
USB 3.0!

do we need hsrdware upgrade for this??and will it be somewhat different from USB 2.0 in terms of plugging?will the pen drives support it??

or we only need software upgrade for this???

Its a hardware update. You will have pen drives, portable hard drives, etc.

oh man!
plz don't make me remember those ones!
i told u about it.

USB 3.0 will usher in the next stage in high speed data transfer on secondary external devices.

All those with USB 2.0 need not dispair. Cheap PCI cards may be available soon with USB 3.0.

here is one such product :

Newegg.com - SIIG JU-P20412-S2 PCI Express to 2-Port USB3.0 SuperSpeed Card - Add-On Cards

found a hard drive on newegg that uses USB 3.0. Its 2TB, costs $870 !!!!

2TB USB 3.0 Portable HDD

There is no end to technology, every month there is a new innovation somewhere and more so in the field of technology. history has show our need for data and data transfer, we started off with a 5" floppy disk which was only able to hold 512 kb and now even a small photograph takes up more space than that... since we need more data, we will also need more speed to transfer data. I am sure USB 3.0 might not take more than 1 year to debut in the market.. in 3 years maybe USB is outdated

Thanks for the useful info
