eSATAp Guide on Windows

    General discussion

  • Dear all, I hope to use this thread to guide users of eSATAp (eSATA + USB) on Windows 7/Xp

    There have been too many questions & misconceptions raised on the older eSATA.

    At this point of writing, eSATAp(Power over eSATA) is found in almost 40% of the notebook. E.g. Sony, Toshiba, Dell, HP, Acer, MSI, Asus, Fujitsu, etc.

    Difference between eSATA, eSATAp, USB 2 & USB 3

    1) eSATAp is also known as Power over eSATA

    2) eSATAp is compatible with USB device (Port wise)

    3) Implementing eSATAp DO NOT need expansive PCI-e card. Simply use a Delock bracket back plate to translate the internal SATA signal.

    This is by far the MOST reliable, since you do NOT need to mess with BIOS AHCI, poor drivers, PCI-e slot or OS registry tweaks.

    Note: eSATAp in IDE mode (Non AHCI) can still achieve 60-90MB/s for a 3.5" 7200rpm HDD.

    4) eSATAp can supply 5v power on notebook & 12v power on desktop

    This means on a desktop you can even power up a 3.5" HDD, SSD, 5.25" Blueray DVD-rw, etc.

    5) This means eSATAp is ZERO drive, NO need BIOS AHCI tweak, NO need driver OS update

    6) eSATAp is hotswappable. If you want a simple method. Download HotSwap!

    7) eSATAp at this point is still faster than USB 3.0.

    8) eSATAp is cross platform (due to SATA)

    In fact apple mac users use eSATA as scratch disk for final cut & adobe.

     

    9) The eSATA port on NAS Storage (e.g. Synology, Qnap, Thecus, Buffalo, etc.) is based on the older eSATA port. It doesn't matter since it is still compatible with eSATAp port. Moreover it is better for them to be on external power supply.

     

    10) If you are buying a portable external HDD, ask for eSATAp NOT eSATA (unless it is NAS).  Even 3.5" can be power up on desktop via eSATAp.

     

    I am currently running eSATAp on a 3 years old VIA motherboard on Windows 7.

     

    In short DROP eSATA, go straight for eSATAp, UNLESS it is NAS (better to have its own power)

    Note: If HotSwap! can do a safely remove hardware. What I would hope is Microsoft to implement this in Windows 7 update.

    Applications of eSATAp

    1) High speed backup & data recovery

    2) High speed cloning

    3) Virtualisation when using an external HDD (USB is SLOW!)

    4) Scratch disk for Adobe & Final Cut

    5) Expansion of storage for NAS

    6) Video editing & gaming via external HDD

  • Dear all, terribly sorry to bring up this post, but there have been some updates.

    1) Industry manufacturers has recently released a bracket that merged USB 3.0 with eSATAp

    Reference: http://en.wikipedia.org/wiki/ESATAp

    2) Secondly I understand Microsoft is supporting USB 3.0 on Windows 8.

    For Windows 7, although one can use Device manager -- uninstall to remove an eSATA or eSATAp device, it is not doable via the green colour add/remove icon.

    Although there is a third party application HotSwap! (red colour tray icon) that allows hotswapping of eSATA, eSATAp and even DVD drives, it would be nice to see this support in later Windows 7 patch of Windows 8.

    Cheers.

  • Hi,

    Can you get us some figures:

    How fast eSATA on windows 7 compared with XP in MB/s?

    The speeds are the same in XP and in Win 7.  The OS is not the determining factor, the hardware is.
