how fast is usb3? i mean real world, say you put a ssd in the best enclosure, what would it do?Reply

The theoretical bandwidth of USB 3.0 is roughly 625 MB/s, but this speed is rarely achieved -- even with the fastest hardware -- because the bus relies on a protocol for transferring data which is poorly optimized and eats up a chunk of the bandwidth.
alidanhow fast is usb3? i mean real world, say you put a ssd in the best enclosure, what would it do?I get like 70~140 MB/s (copying from WD my passport 1TB to my WD HDD (7200rpm black))Reply
and I get 30~40 MB/s copying from USB 2 WD my book 2TB to ^^^^^^^^^^^^^^^

I'm sitting here, daydreaming about a Velociraptor external drive. Maybe that would be able to use the USB 3's capacity better, or maybe something's slightly wrong in my head for wishing for such a thing.Reply
willyrocUSB 3 is more than twice as fast as USB 2.Yeah but you're still limited to both the source and destination drive's read/write speed. So when copying from a HDD to an HDD, you're unlikely to exceed 140 MBps.Reply
If you're copying from a SATA 3 SSD to a USB 3.0 SSD, then yes, you could see much faster speeds.
USB 3.0 + UASP (or) eSATA (or) Internal (SATA 2 or 3) HDD.Reply
USB 3.0 in most instances isn't ready for prime time for external HDD's, and without UASP the queuing is too slow; UASP solves this problem. Otherwise without UASP IMO use eSATA or a backup internal SATA HDD.

So... Theoretically USB 3.0 is faster than eSata, but in practice eSata is still the way to go?Reply

that 1tb is in a better case than the 2tb
what i have noticed with usb 3 is that, yes while its theoretical max is higher than current hdd and ssds should achieve, the fact of the matter is they never hit that peak.
thats why im wondering, with an ssd, what is the best we can get usb3 to.
you proved that current normal hdds in a good case do not have a problem in usb 3, and for that i thank you.
