Windows 7: SATA drive in USB3.0 Enclosure

Have you got more hardware details??

Im using a 2.5" Momentus 7200.3 notebook drive - 500gb, 7200rpm, 16mb cache. Its connected via a usb3 cable to a usb3 drive with renesas usb3 driver loaded. Im shocked that the drive is so slow - in usb2 i get 19mb/s sequential but usb3 only gives me 30mb/s....but then it slows down to a crawl 1mb/s - i have updated the driver as this sriver is the second one released by Dell but thought that i should get up in the 50-60mb/s - i say this because the iomega has a usb3 external drive out that can reach up to 10 times faster - even though the drive inside is a 5400rpm

I understand you are using a USB3 cable and the hdd is not in an enclosure is this correct?
If so then the adaptor between the two components will also have to be USB3 compliant

The HDD is in an enclosure and the adapter is usb3 compliant - the enclosure i bought was this one below

You basically insert your hdd and its converted to usb3. I know 100% that my usb3 driver is loaded and the correct version, and i know that the system definitely has usb3 ports (2 of them, 1 usb2 and an esata)

Then it should be working

Try testing it with ATTO http://www.techpowerup.com/downloads...ark_v2.46.html

Tested with ATTO - the results are below

ps do these speeds look normal - they ceetainly are not "10x faster than usb2.0" as advertised

No they are not and the write speeds trouble me as I think they are slow.

This is a capture from one of my 2.5 drives the write and read speeds seem to be more centralised

Just to remove all doubt that the USB3 driver is working try connecting to a USB2 port and repeating the test

Here is the same test but via usb2 - im so shocked as to how slow the speeds are, and although the usb3 speeds are a little faster, they are quite pathetic considering they are supossed to offer more speed. I mean, there are some compact flash cards that are faster here than my usb3.0 drive

Yes I believe you that it is very disappointing and I cannot explain why it is so slow I also doubt that we will be able to improve on these speeds.
I have just had an interesting thought, but don't get your hopes up. How full is this external drive?
