A Look at Excessive Portable Storage 101

Tom's Hardware has an interesting look at portable storage devices that fall a little outside of the normal bell curve. The reviewed items include Buffalo's all-flash portable storage drive, Chaintech's flash SSD w/ an additional USB port, and LaCie's state-of-the-art RAID drive based on two 2.5" drives. LaCie's drive seemed to come out on top for usability and performance with the main downside being the $600 pricetag and lack of adequate backup software, but all had interesting advantages.

    I've been using a G-RAID mini [] for a year or so. The drive I have is only 500GB, but it's fast (for a portable drive) because of the RAID.

    There's a 1TB drive coming out soon - see the 'mini-2', which looks to be $699 before any discount (I got ~25% on the mini IIRC).

    G-Raid is also a *lot* more reliable than Lacie, in my experience but I guess YMMV, one view is not statistically relevant etc. etc.


    • I spec'd out a external RAID solution for backups the other week. Several two-drive setups with eSATA are available for less than $200 on Newegg (no drives included). So for $500 dollars I could put together 1.5 Terabytes of mirrored storage (3 Terabytes striped). There are cheaper JBOD setups, but they aren't what I'm looking for.

      I wound up buying a simple 1 Terabyte drive + enclosure instead for $100.

          Finally, some common sense. Even if you could trust the RAID card and the rest of the circuitry, your data, if stored in anything other than a simple mirror configuration, is tied to the unit. No different than a RAID card of course.

          These units do seeem to fill a largely unmet need, and while they offer lots in the area of convenience, I'd suggest they're a poor bargain given the uncertainties and potential for losing one's data. Too bad really. Build

    I don't think software requirements are keeping up with the newer hardware. True, I am writing this from FireFox installed on my flash drive but there is often very little consideration by many software developers for the needs of the portable software market. So much of it expects data on c: or writes to the registry. Since flash memory quality benchmarks are based on number of read/writes before failure it will be interesting to see how the newer USB hardware will stand up particularly with applications such as browsers and email that do extensive read/write operations.
    • don't worry about c: and registers... install one of many versions of Linux to your flash drive and have a full portable OS and software like open office and firefox. leave a portion of the drive open to save files and settings. Or get fancy and put in persistence.
      • I would but I read somewhere that flipping the removable bit on San Disk flash drives is unpredictable (it could ruin them).
        • What exactly are you referring to? What "removable bit"?
          • Older computers like mine will not boot from flash drives. One way around this is flipping the removable bit. This bit tells the OS that the drive is removable. Once the bit is flipped the OS treats the drive as non-removable so it can boot from it at start up. This can be done via software.

      You can carry a ton of compilers/frameworks/parsers, along with libraries (including their sources), and have your choice of IDEs and helper programs installed all in one place.

    Who in the world is this LaCie external drive made for? It has 2 500GB drives included, which can be run as RAID 0 or RAID 1. For the $600 price tag, I could purchase 5-6 external 1TB drives.

    These things are most likely being used to store music and videos. I almost feel bad for all the people who buy one of these, set it to RAID 0, and then cry in a year or two when one of the drives die and they lose their data. If they had used the money to purchase backup drives instead, they would be fine.

    The only possible advantage is speed, but the speed just isn't needed except for special applications, in which case it would be better to simply build a computer.

    Here's the craziest thing about the $600 price tag - I could build an entire new computer running Linux, with a software RAID setup and twice the storage, for less money.
