Performance in FC-Test
Now let’s see what we have in FC-Test. For each test we’ve got two tables (reading and writing) that show the performance of the drives with USB 2.0 and 3.0.
It’s easy to note that the drives are similar when reading a single 900MB file over USB 2.0. The only exception is the cheap and slow ADATA, yet even its performance is far from a total failure.
Every drive speeds up on the EtronTech controller but to a different degree. The ADATA is rather indifferent about the interface, the Corsair adds just a little to its USB 2.0 speed, but the two drives with native USB 3.0 double their performance.
When writing the same file, the drives differ even on the USB 2.0 controller. The Kingston falls behind in the leading trio whereas the low-end ADATA is much slower than its opponents.
When we switch to the USB 3.0 controller, the Kingston goes ahead and is followed by the other native USB 3.0 drive. Next goes the fast USB 2.0 drive from Corsair whereas the ADATA is hopelessly slow.
When reading medium-sized files of the MP3 pattern, the tested drives have almost the same standings on the USB 2.0 controller as in the previous test. The Kingston is somewhat slower than the Corsair and Kingmax whereas the ADATA is the slowest of all.
The standings are exactly the same as in the previous test when the drives are connected to the USB 3.0 controller.
We’ve got a different picture at writing, though.
First of all, we can see that the Kingmax fails this test irrespective of the USB controller. It’s even slower than the cheap ADATA with the USB 2.0 controller and cannot leave it behind on the USB 3.0 interface. These two drives are much slower than the Corsair and Kingston.
We should also note the Corsair’s excellent USB 2.0 performance and the superb results of the Kingston in USB 3.0 mode.
The ADATA drive shows a decent result when reading a folder with Microsoft Office 2007 (a lot of small files with but a few large ones: 3384 files with a total size of 450 megabytes). It beats the Kingston in USB 2.0 mode. The Corsair and Kingmax are ahead with similar results.
When connected to the USB 3.0 controller, the Kingmax is in the lead, followed by the Kingston. The Corsair accelerates on the USB 3.0 controller but cannot catch up with the native USB 3.0 products.
Writing a large number of small files is the most difficult test for flash memory. We’ve got two pairs of leaders and losers here. The ADATA and Kingmax are slow and cannot deliver 1 MB/s even. The Kingston and Corsair are in the lead, the Kingston enjoying a considerable advantage over its opponent.
