The article states SATA 3.0 should have a maximum throughput of 6 Gbits/second. But isn't that the same expected throughput of USB 3.0? What advantage would I have in using SATA 3.0 (Revised?) over USB 3.0?
- pmjordan 17y ago* SATA is point-to-point, so each drive gets this bandwidth. USB is a tree, bandwidth is arbitrated between devices. * SATA 2 came into commercial use relatively shortly after introduction. I haven't seen any USB 3.0 devices yet (host adapters/motherboards or nodes) and driver support during the USB 1.1->2.0 transition was pretty bad. Apparently, Windows users will need to wait for Microsoft to release host controller drivers. I suspect they'll only be available for Windows 7. No idea when OSX will support it, presumably Linux will be first, assuming the spec is made available to the developers.
- MetricMike 17y agoThanks! I've been trolling the Wikipedia pages for both of them but that's easily the best summary I've come across so far. =)
- pieter 17y agoAlso think of stuff like latencies. Current USB drives add like ~5ms of latency. That's doable with normal drives (which have ~10ms access times), but is killing for SSD's (which have <0.1ms access times).
