TwinMOS A3 USB3.0 drive Quick Look

Looking for a speedy little drive?

Today we take a quick look at the TwinMOS A3 USB drive that is based on the new USB 3.0 standard. Available in 8GB, 16GB and 32GB capacities and in brown, blue and black, the drive comes packaged in a plastic shell that needs scissors to tear which is a bit impractical but I guess helps preventing people from swiping these things from their packages without paying for them.

The TwinMOS A3 measures 4cms without the USB connector which is pretty much average in size compared to the rest of the USB drives. TwinMOS uses the blue color on the USB connector to denote that the A3 is USB 3.0 compliant. A red LED on top of the USB stick lights up letting you know when the drive is in use.

We popped the drive into both USB 2.0 and 3.0 slots and ran SiSoft Sandra. Our USB 3.0 controller is by Etron and was onboard the ECS P67-H2 motherboard. For comparison, I also threw in a Kingston 8GB stick. The following table shows the read and write speeds using CrystalDiskMark with a 100MB file size and number of runs set to 3.

TwiMOS A3 Read (USB2) TwiMOS A3 Write (USB2) TwiMOS A3 Read (USB3) TwiMOS A3 Write (USB3) Kingston 8GB Read (USB2) Kingston 8GB Write (USB2)
Sequential 34.37 17.36 54.21 16.34 23.78 8.19
512k 34.17 6.06 52.38 10.56 23.27 4.05
4k 5.59 0.12 11.51 0.19 2.58 0.52

As you can see from the table above, the TwinMOS A3 performs very well when it comes to sequential reads and writes as well as 512k but slows down considerably in smaller 4k files especially when it comes to writing where the Kingston excels. Considering the nature of USB drives, we doubt you’ll be using it much for files of around 4k size- most people use it to carry songs or pictures which are much larger in file size making the TwinMOS A3 a pretty good product.

Priced just right at AED 75 (USD 20) for 8GB, the TwinMOS A3 is very much recommended if you are planning on getting a USB drive. With USB 3.0 capabilities, it will not only work well with your current computer but is future proof until USB 4.0 comes along.
