ATTO Disk Benchmark

The ATTO Disk Benchmark program is free, and offers a comprehensive set of test variables to work with. In terms of disk performance, it measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. There are some minor improvements made to the 2.46 version of the program that allow for test lengths up to 2GB, but all of our benchmarks are conducted with 256MB total length. ATTO Disk Benchmark requires that an active partition be set on the drive being tested. Please consider the results displayed by this benchmark to be basic bandwidth speed performance indicators.

500GB Samsung T3 ATTO Benchmark Results

Although the results are much faster than those from an external USB-powered hard drive, the Samsung is still slower than an internal SATA drive.

    Driver needed for Mac? See warning for previous model at
    Mac Owners Should Hold Off on New Samsung T1 Flash SSD

    Can it be used to boot Mac and work from it all day long?

    RAID 0 inside as in SanDisk’s 1.92TB Extreme 900 Portable SSD? That is the best way to lose data (2x probability or more). One disk fails (or controller), all lost.

      The T3 drive comes with the necessary software to run it on a Mac, included the SAT driver mentioned in your link. I tried the drive on a Mac and had two minor issues: the first time I ran the installer, it installed the security software, but not the SAT driver, so the drive was inaccessible. Running the installer again brought up the option to install the SAT driver. Second, the “T3 Login Activator for Mac” utility you need to unlock an encrypted drive doesn’t “see” the T3 if it’s connected when you boot the Mac– you need to unplug the drive and then plug it in again.

      I copied over 200GB of video files to the drive (simply by dragging them over in the Finder) and saw a transfer rate of about 1GB every 7 seconds, or about 140MB/second.

      I don’t see any way to use the T3 as a boot drive for the Mac, since their installer will not install the security software and SAT driver on the T3 itself. You might be able to hack around this by manually transferring a preconfigured system folder, but I wouldn’t recommend it. In any case, an internal SSD would be much faster than a USB 3 SSD.

        Thanks. I guess you mean when using the T3 security software. I guess, no problem when not using it.

        Sure an internal SSD could be faster, but booting from external Thunderbolt or SSD is very convenient as Mac to Go (like Windows to Go) to carry your stuff and boot from Mac at work and home.
