Mukii vs STLab USB 3.0 PCIe card

, posted: 21-Jul-2011 15:47

We needed a USB 3.0 PCIe card for use on a backup Windows 2008 R2 server so we ordered a Mukii TransImp USB3.0 card.

Features :
  • Supports PCI Express Base Specification Revision 2.0
  • Compliant with USB 3.0 Backward Compatible With USB 2.0.
  • Transfer rates up to 5Gb/s with USB 3.0.
  • Each USB port supplies maximum +5V / 900mA power output to USB device
  • Gold plating USB connector
  • USB interface for easy data access.
  • Built-in SATA power connector for receiving extra power supply from system
  • Low-profile bracket included.
  • Hot Swappable :Plug and play
  • Support Windows VistaR , WindowsR 7, WindowsR XP

It installed via the supplied driver CD without any hassles (surprisingly, the CD driver was more recent than the support websites).

I then plugged in a Iomega eGo 1TB external USB 3.0 hard drive and proceeded to test the performance by copying a folder containing 3.16GB of files of varying sizes.

Results were disappointing.

I was only getting 5MB/s transfer from the local hard disk to the eGo - I then installed the card into a Windows 7 workstation to make sure it wasnt the server at fault. Same result....

My boss then had a play and moved the cable from port 1 on the card, to port 2 and started getting 30MB/s rates.

Still not what we were expecting, so I ordered a ST Lab card.

Installed it on the workstation again using the supplied drives. Straight away we were getting 50-60MB/s transfer rates.

Moved to the server and same results - copying the 3.16GB of data in 1 minute.

Why the Mukii was having issues, we dont know, looking via Google found us users who were quite happy with the card and not having any issues.

So, might be time for me to get USB 3.0 at home....  3GB in 1 minute is appealing when you have 25GB of photos to backup....

Still seems low though. While I don't expect a ten-fold increase in performance over USB 2.0, I'd expect something in the region of 80-110Mbyte/s depending on which drive Iomega uses for the eGo.

Good tip. I hate spending money on stuff that doesnt work as advertised and a USB 3.0 card is on my list.
