USB 3.0 faster than SATA ?

0	Do you think that USB 3.0 is faster than SATA for data transfer ? usb speed sata asked Jun 08 '10 at 07:06 brewey 31●11●14●18 edited Jun 13 '10 at 05:53 Seb (suspended) You mean faster right? (Jun 08 '10 at 07:39) Headwards

SATAII currently has transfer speeds of 3Gbit/s. Please note difference between Gbit and GByte (8 bits to a byte, 8Gbits = 1 GByte) and USB 3.0 is reportedly gonna support transfer speeds of unto 4.8Gbit/s so to answer your question, yes it looks like USB 3.0 is gonna be "fatter" (faster) ;-p

See my answer. It's not fair to compare a new standard against an old one.

2	SATA III has transfer speeds of up to 6 Gbps, which far outperforms USB 3.0. answered Jun 14 '10 at 16:43 eddieringle 2.3k●7●16●44 simple yet direct i like it(Y) (Jun 16 '10 at 09:49) jakek090

Faster for what? USB 3.0 isn't specifically designed to be an interface for hard drives. SATA II is. Sorry, but I beg to differ. SATA II will be faster, due to the fact that USB tends to grossly overexagerate by providing a "theoretical speed" instead of a "practical speed". This is well documented: "The actual throughput currently (2006)[update] of USB 2.0 high bandwidth attained with real-world devices is about two thirds of the maximum theoretical bulk data transfer rate of 53.248 MiB/s." 2/3rds of 4.8Gbit/s is 3.2Gbit/s. If this trend carries through to USB 3.0, then SATA/eSATA II would still likely be the wise choice for hard drives, because a controller will still need to belong somewhere in the interface.
