USB 3.0 So slow?

Hi, i recently bought an expresscard usb 3.0 and a 3.5" enclosure usb 3.0 from eBay. I install the usb 3.0 driver for the expresscard, plugged in my hard drive and got it to work. But the results are of transfer speed is extremely slow, almost no increase from Usb 2.0

I transfer a file to my laptop at around 35mb/s when the hard drived is plugged into Usb 3.0 port

When i plug it into Usb 2.0 it transfers at around 26mb/s. 9mb/s increase only???

From laptop to hard drive... Usb 3.0 - 32mb/s
Usb 2.0 - 24mb/s

Ive seen videos showing around 120mb/s of transfer speed.
What is going wrong?

EDIT: Btw, im using a 3.5" 7200rpm hard drive externally powered.

 

these links may be of help:

What kind of files were you transferring?

 

random movies, some were around 1gb some 4gb, all roughly the same results.

 

Romiyo: Do you have any other USB 3.0 ports on any other computer available to see whether the enclosure is holding your speeds back?

Anyone else on this? I was looking to buy the same adapter.

 

Expresscard usb 3.0 is only half of the speed of usb3 speeds.
You will need usb3 flash drives, ssd-s, or hdd in raid ... single hdd-s slow as hell

 

I also thought this ??

 

it all depends of the write speed of the recieving drive

when loading data through my esata from a usb hdd to my raid array i get 70mb transfer rate when loading from the raid array to the usb drive i get 36

 

I don't mind stepping down from 5Gbps to 2.5Gbps maximum, it's not like many hard drives can reach 300MB/s sustained.
I have a USB 3.0 hard drive already (just got 2TB recently for $80! ) and so I was looking to improve my system image copy times from 8 hours to anything shorter.

5Gbps = 625MB/s
2.5Gbps = 312 MB/s

Even considering a massively overestimated 50% overhead for whatever reason, that's still >150MB/s. I'll take that for a single drive over my current USB 2.0.

So now my main issue is, what USB Expresscard works well?

 

Expresscard USB 3.0 is only a stop gap until laptops with 3.0 become mainstream. Nevertheless, it's still a vast improvement over USB 2.0. Which I think is the point.

 

This one works great. It doesn't fit quite flush with my MSI GX740, but only sticks out very slightly. It's far more aesthetically pleasing than most traditional Expresscard adapters. You also get a DC-to-USB power cable, which is only necessary if you have a high-power-draw device. It uses the standard NEC/Renesas drivers, which you can download from here.

I have a WD MyBook 3.0 attached to that card and have had no problems thus far. I did a quick benchmark of it with USB 2.0 as well as USB 3 with and without the power adapter attached.

 

Dude saturnotaku you're my savior. I just bought that card on the count of it was cheapest, smallest, I had a coupon, and figured I couldn't go wrong.

Those benches are excellent and thanks for the driver link!! You've saved me hours of searching.

 

Which one of the drivers are you using? There are so many on the page...

 

I'm just thinking - if you get USB 2 speeds, could the internal connection for the ExpressCard be USB based?

 

The latest ones at the top of the page.

 

FWIW

I'm using cheap Dynex eSata ExpressCard which gives me peak 103MB/sec at 87MB/sec average if you trust the HDTune benches.

All my USB2.0 Drives average around 15-25MB/sec on my 2 year old P6831..

 

I guess "FWIW" should be this?
What does FWIW stand for?

 

LOL.......yes!

 

I kinda was curious about USB3, since i have a desktop with Asus Sabertooth X58 and G73JW that both have USB3, so i bought a usb3 docking station.

The test is moving a folder with 13.7GB, mostly 250mg avi/mkv/mp4 videos and some mp3s.
Desktop HDD = Samsung HD502HJ
Laptop HDD = Hitachi 7k500
Dock HDD = Hitachi 5k500B

From the Dock to Desktop = 2m 51sec
From the Desktop to Dock = 4m 34sec

From Dock to Laptop = 3m 20sec
From Laptop to Dock = 5m 20sec

On the slowests (from the computers to the dock) from what i remember the windows display transfers were around 45 m/s. On the fastest (dock to Computers) the windows display was around 70 m/s.

Interestingly i took out an eSata docking station and tested with all the same (no laptop test as i dont have esata on the G73)
From Dock to Desktop = 3m 36sec
From Desktop to Dock = 5m 15sec.

 

I'm using an USB 3.0 express card and have a 640GB HDD in an 3.0 enclosure, and when I move files from the computer to the drive, via USB 3.0, I get transfer speeds of about 70MB/s. My guess is that if I used an SSD in the enclosure, speeds would be faster. The 640GB 5400RPM is probably the bottle neck. All in all though, I'm happy with the express card. It's a nice little upgrade to my system.

 

I ran crystaldiskmark on all setups just out of curiosity, here the results

 

I just got the USB 3.0 expresscard set up and ran a quick HDTune bench.

USB 2.0/ 3.0/ xImprovement
In MB/s:
Minimum: 29.6/ 62.2/ 2.1x
Maximum: 33.2/ 118.2/ 3.56x
Average: 33.1/ 101.2/ 3.06x
Burst: 27.5/ 94.7/ 3.44x

Not bad for a $19 card! Really happy so far.

EDIT: I just completed a system image backup (430GB) in less than 3 hours. It took me more than 8 hours last time.
