Nine USB 3.0 Flash Drives For Road Warriors

Features

The best ultra-portable USB 3.0 storage products from 16 to 128 GB square off in a grand comparison. We found wildly disparate transfer rates ranging from 200 MB/s down to a snail’s pace. At the end, though, two products rose to the top of our list.

Patriot Supersonic (64 GB)

The Supersonic is Patriot’s USB 3.0 flash drive. We received the 64 GB version for testing and a 32 GB model is also available, with higher capacities still to come. The 64 GB comes in around $180, while the 32 GB model can be found from around $125.

The drive's case is aluminum. The black color is different from other vendors' solutions, but the quality impression is neither positive or negative in any particular way. The manufacturer claims 100 MB/s reads and a 70 MB/s writes. Our test returned a 125 MB/s read throughput and 83-36 MB/s when writing. In practical testing, the results varied considerably.

Especially with small files, the Supersonic struggled and ranked poorly among its competitors. When we transferred 22 704 files with a total size of 2 GB, for example, the Supersonic wrote them with an effective speed of only 800 KB/s. Conversely, files several megabytes in size were written quickly at more than 20 MB/s. It is therefore strongly recommended that small files be added to a RAR or Zip archive prior to sending them to the Supersonic. The time saved copying more than makes up for the time it takes to compress them. The Supersonic, like the A-Data and PQI devices, offers very weak I/O performance that is not suitable for concurrent accesses on the USB stick.

    Conclusion: This article ignores encryption.

    The article is a complete failure. You THG people ignored encryption as a metric. Why??!!
    Flash drives are cheap. Company information and regulatory items (HIPAA for example) are priceless.

    I'm a "road warrior" that depends on a flash drive for my daily work: IRONKEY. My employer provides it. I am legally required to use it. It is hardware encrypted. The drive might be stolen or lost, but the data will not seen by any unauthorized user.

    If I lose my drive, the physical media is lost. I have medical databases that I am required to keep secret via government regulation. My drive will wipe itself after 10 incorrect login attempts.
    Do any of the reviewed drives on THG do this?

    Extremely good read, what i liked was that the companies are not making false claims anymore most of them performed as was claimed.

    This in my opinion is altogether a different topic and should be covered in different article where the encryption also as well as over performance be compared.

    Agreed, I'll pass that feedback along to the author.

    If you actually read the article, you would know that the SuperTalent SuperCrypt encrypts its data with a password, like the IRONKEY. Maybe you should read.

    I did read the article. One drive supporting cryto does not a metric make, which I mentioned. That feature is an anomaly and not a fundamental feature (metric) of the article.

    "Maybe you should read."
    Reading is good. Comprehension is even better. I suggest you begin there, since you obviously cannot do that.

    Your post reads like an advertisement and you complain that they didn't do an encryption comparison when only 1 drive supports it at hardware level. On top of that cant you read, this is a USB 3.0 test, ironkey only does 2.0. Furthermore your employer provides your drive so what difference would it make if they said your ironkey was a slow but safe piece of $#!t? This is an everyday-user drive roundup for fast file transfer, not a business specific roundup that would be useless to most tom's readers. You said it yourself, your company provides secure storage since they expect you to move important files. Typical users won't need this and if they do the decision most likely will be out of their hands. Additionally in a security environment the protection far outweighs the need for speed, so the test metric would be completely different than how consumer grade drives would be tested.

    tl;dr
    You don't seem to comprehend the use of your drive and what features the owner actually values.

    some test with encryption enabled are missing. what is the impact of an encrypted drive? what are the encryption option?
    we do not always looking for speed, we are also looking for backup or archive of sensitive data.
    and other peoples are looking for speed only, for sure, because they hate loosing time in data transfert :)

    but the same questions are also for classic HDD, not only USB keys.

    I purchased a 16GB A-DATA S102. It's not a premium product, but it does receive a significant performance boost from USB 3.0 (according to other reviewers; my USB 3.0 laptop is still in Fedex's hands). The drives in this review, I think, are for those who need only the best features and performance. The average user can still get better performance out of a "regular" USB 3.0 flash drive.
