#Usb 3 transfer rate in mb install
Is that the best you see even while copying a single large file, such as a Windows Install ISO? If you're on Windows 7, do you have the latest Intel USB 3.0/xHCI drivers? I know they've been revised quite a bit over time. Even then though, unless you're copying a lot of tiny files, 35 MB/s write to a USB 3.0 disk is pretty bad, even a smaller one like 500GB that would likely have lower platter data density. Even taking that into account though, I too have seen implausibly high speeds reported by Reflect, so I'm wondering if that rate is measured by the amount of source data being read/written rather than the amount of data being read/written at the destination - which can be a very different figure if you're using compression and achieving a decent ratio. Well first, be aware that to convert Mb to MB you have to divide by 8, so 739 Mb/s write is 92 MB/s. The only eSATAp device I remember using was a Dell external optical drive that was an accessory specifically for a Dell laptop my wife bought that didn't have one built in. A few vendors did indeed include eSATA p connectors that offered power (via USB power pins in eSATA+USB combo ports), but that was never widely adopted because it came too late. For 3.5" drives that require separate power anyway, yes eSATA was a great alternative to USB 2.0, but by the time eSATA came around, 2.5" drives offered enough capacity for "most people" and they liked the portability and single cable convenience. My point was that the standard eSATA connector didn't provide power AT ALL because it only included pins from the internal SATA data connector, not the additional power connector that internal SATA disks require - and that made eSATA unsuitable for form factors like 2.5" external drives where the expectation is that they'll be bus-powered, as they are when they use USB. I had lots of Systems that only had li'l backpanel connectors (eSATA FEMALE) that connected passively to the internal SATA connectors. Most eSATA connections were passive (no power issues) and only differed from SATA by connector and cable length.
