How To Get The Best I/O Transfer Rate Using An External HDD Enclosure?

Hello All,

I just purchased the ASUS MAXIMUS VII GENE Micro ATX motherboard and a BitFenix Phenom Micro ATX case.

I use an external hard drive to backup my data and I am constantly transferring large amount of data. Currently I have a USB 3.0/eSATA external enclosure with an HGST Travelstar 7200 RPM HDD connected to a Super Speed USB 3.0 card. When I run Crystal Disk Mark I get ~110 Mb/s read and ~100 Mb/s write transfer rates.

The ASUS GENE motherboard has the following interfaces:

[Expansion Slots]
2 x PCIe 3.0/2.0 x16 (x16 or dual x8)
1 x PCIe 2.0 x4
1 x mini-PCIe 2.0 x1

1 x M.2 Socket 3, , with M Key, type 2260/2280 storage devices support (PCIE mode)

[Back Panel]
4 x USB 3.0 (blue)
4 x USB 2.0 (one port can be switched to ROG Connect)

I am also going to add the following:

[PCIe x4 Slot]
Inateck Superspeed 4 Ports PCI-E to USB 3.0 Expansion Card

Note that I will have 1 open slot on the back of my case since there are only 3 PCIe slots on the motherboard and 4 slots on the case.

Given all that information and also the fact what kind of external hard drive enclosure would give me the best performance?

Thank you,

    If you are using a mechanical hard drive then the USB 3 that you are using should be fine. If you are using an SSD then eSATA would be better.
