Read/Write Throughput

Storage Accessories For Easier HDD Handling

The read throughput we’ve seen on the Crucial and iStarUSA devices is very close to the maximum performance we achieved with the test drives when they were operated on the internal reference storage controller. iStarUSA is able to capitalize on the full real-life maximum throughput of USB 2.0, which is approximately 32 MB/s, while Crucial’s SK01 kit stays below 27 MB/s. The Unitek SATA HDD Dock achieves nice USB 2.0 throughput even when using a high-speed 266x CompactFlash card—clearly, the card reader is a high-performance device.

The results are similar for the write performance tests. USB 2.0 limits the throughput of all devices to 25-27 MB/s write transfer rate, while eSATA allows all products to unleash the full performance of the drives they host.

    We really need USB 3.0 for external hard drives.

    we'll get there soon.

    Its too bad the Unitek Docking Station wasn't on a faster interface, but its still a great piece of hardware, I might actually invest in it.

    Do all of these allow you to plug in and later remove a SATA drive while the computer is powered up? Do you do the same "Safely Remove Hardware" step with a SATA drive that you do with an external USB drive?

    "However, the build quality was so poor that we had to open the device and relocate the SATA connectors....."

    is it because Made In China?

    Imagine a usb 4.0 that will eventually replace SATA ^.^

    I can recommend the Sharkoon Quickport PRO (which looks remarkably similar like the HDD Docking Station by iStarUSA). I thought my 3 yr old SATA Maxtor harddrive had died: I couldn't hear it spin, a Windows installation bootcd wouldn't detect the drive... and hooked up inside a different computer in Windows it was unable to read/copy any data. However the Sharkoon docking station (with eSATA) had no problems reading it whatsoever and I could save all the data. :-

    the gigabyte ex58 ud4p came with this cool io bracket, it let you convert 1 or 2 internal sata ports into e-sata ports, and more importantly, convert one internal molex power plug into 2 external sata power plugs, came with all the cables you need, and you could use it in any computer.

    China assembels everything from iPhone to even Sony LCD panels. Production location has nothing to do with it. Price points do. You pay for crap or buy dodgy unbranded items thorugh US-importers who markup unscrupulously, then guess what - you end up with crap. Look at all of your electronic items - including the branded "quality" items. Most are made in China.

    A friend of mine has bought the "iStarUSA HDD Docking Station (xAGE-N99-SAU Drive Dock)" and he lend it to me to use it for a while.

    I did not notice the eSATA plug problem and it was very fast as the benchmarks showed. The whole black appearance is very sleek and it does what it says for a very small price.

    When comparing to Unitek model, I would go for the iStar for 4 reasons:
    1) It is cheaper
    2) Most people already have card readers or USB hubs or simply at least 6 USB ports.
    3) Subjective comment: Who cares about one touch backup and additional software, I personally don't
    4) Subjective comment: I wouldn't put this ugly thing on my desk :p

    I've had my iStar xAGE-N99-US/SAU Toaster for years without problem, didn't remember the make or m/n so I did a search and found this page. Forgot it was an iStar and that it had an eSATA connection. Looking for another toaster with the same features.
