    5 x SATA 3.0 Gbps ports (internal drives)
    1 x eSATA 3.0 Gbps (external back panel)

    eSATA is #8 on back panel

    SATA 3.0 Gbps is about a maximum 375 MBps. Current drives are SATA 6.0 Gbps. With a USB 3.0 port you can do better than this speed at about 400MBps second. USB 3.1 is even faster.

    I am using the single bracket of that type but I had to drill a hole then cable through a cable & make a new molex connector to power my USB & Optical drive setup setup.

    Unfortunatley I have to mount mine on the side of the case because the Sata cables are not long enough (15" is 2" too short) to reach the Sata ports which face toward the front of the full size motherboard.

    There is nothing wrong with still using eSata to Sata externally as it is still 6GB/S Read/Write & with my USB 3.0 hub I get fast read but it is limited to 40mb/s write speed, but at least that is constant going to my usb hdd's

    Another thing to remember is even though SATA and eSATA are technically the same thing they differ in how they are intended to be used. Regular SATA was only supposed to be used with internal drive while eSATA was designed for external drives. My motherboard had two SATA controllers. One was for internal SATA drives while the second was for the eSATA on the back plate. eSATA also used different cables & connectors than regular SATA ones.

    External SATA, or eSATA, uses more robust connectors and supports a cable length of up to two (2) meters.


    I powered up my old computer with eSATA and found some benchmarks results from back in 2011,

    Average read speed
    SATA = 145 MB/S
    PATA/USB = 30 MB/S
    SATA/USB = 31 MB/S
    eSATA = 70 MB/S

    Average write speed
    SATA = 114 MB/S
    PATA/USB = 32 MB/S
    SATA/USB = 33 MB/S
    eSATA = 53 MB/S

    SATA = Drive1
    eSATA & SATA/USB = Drive2
    Drive1 = Western Digital Caviar Blue, 1000 GB, SATA (6.0Gbps)
    Drive2 = Seagate Barracuda, 300 GB, SATA (3.0Gbps)
    Drive3 = Maxtor DiamondMax Plus 9, 160 GB, IDE/PATA (1.0Gbps)

    Note1: Drive 1 (SATA) is only faster than Drive 2 (eSATA) becaue it is a faster drive
    Note2: Even though Drive2 is SATA and Drive3 is PATA the USB speeds are about the same because the speeds are limited by USB itself.

    stiggs third image is similar to what the front panel of mine looks like, also a Coolermaster case.
