In what certainly is interesting news, comes word of the NewerTech eSATA to USB 3.0 Adapter. This is  not the first such adapter we have heard of, but it is the first to claim to be the fastest with benchmarks to back it up.

The NewerTech claims that it can do 247MB/s reads and 206+ MB/s writes (assuming your eSATA device is capable of this) which is very impressive as up until now the adapter itself has been a huge bottleneck adding in nearly unacceptable amounts of overhead.  You may be asking yourself why would anyone need a USB 3.0 to eSATA adapter and why would anyone care if it can do all that conversion without reducing power.

The answer to the second question is actually pretty simple as while a couple MB/s on 200+ devices is neither here nor there, that amount of performance hit on say your typical 2.5″ hard drive would be huge. Less really is more when it comes to performance impacting adapters. As for the first question only you can answer that one, but wouldn’t it be great to be able to use your eSATA external device on all your systems even those that don’t have eSATA.

This is not as outlandish as you would think, as while eSATA is very prevalent in desktops, USB 3.0 is becoming a heck of a lot more ubiquitous in portable drives with eSATA becoming as rare as hen’s teeth! Heck, even if your laptop doesn’t have USB 3.0 ports it certainly has USB 2.0 and while that is not much bandwidth something is better than nothing! You can pick the NewerTech eSATA to USB 3.0 Adapter up now from retailers (such as OWC) for $29.95.

  • SATA III is now being shipped in Laptops as of early 2011.  That’s 6Gbps for internal SATA and eSATA!!  So NewerTech better make a eSATA to USB 3.0 that can keep up!

      USB 3.0 tops out at 5 Gb/s. Not gonna happen.

    The title of this article is a lie. There is a difference between going from eSATA->USB3 and going from USB3->eSATA. I have not found a device to do USB3.0->eSATA as the title of this article claims. The text of the article clearly indicates that it is eSATA->USB3.0, not the other way around.

    • It goes both ways, look at the picture at 0:15 in the video.

        From NewerTech’s website: “NOTE: This adapter is intended for an eSATA equipped external drive to connect to a USB 3.0 port on a computer. It does not work in reverse and will not allow a USB 3.0 equipped external drive to connect to an eSATA port on a computer.”

          eSATA ports do not provide power, USB ports do. This adapter is not connected to power, therefore, this adapter works when its USB connection is made to the computer and its eSTATA connection is made to the external HDD as PacoBell states.

            This is more or less correct, although the eSATAp standard combines USB with eSATA into a single port. One can purchase eSATAp adapter cards if one isn’t built into your device.

            Some external HDs like my segate 3tb have an external pws if necessary but it’s still annoying that you can’t connect to an obviously faster port eSATA because there is no power not to mention running an external HD on a laptop USB drains the battery quickly. I ran norton ghost to backup a 30 gb partition and it killed my brand new 9 cell laptop battery before completing 80% of the backup when using my external HD on USB2 power only, but not when i used the laptops DvD writter but i had about 7 mins of battery life left using the dvd writter with regular 4.5gb dvd’s. Still the dvd writter completed the task while the USB2 drive did not. Each test was done from a fresh fully charged battery and settings using full compression with verify.

    I have the same inquiry. I am trying to find a fast adapter that will
    take large capacity portable HDs that have usb3 enabled or even usb2
    connections and convert them to run on the computers (laptop or
    desktop) that have eSATA ports. Some systems do not have the space or
    slot for an add-on usb3 card including many recent laptops and it would
    be nice to have something much faster than usb2 when dealing with ex.
    3TB of data, especially when eSATA has between 3 and 6Gb/s.
