Hi-speed USB2 Flash Drive Round-Up
An anonymous reader writes "Ars Technica has a USB
2.0 Flash drive review featuring 8 drives from different manufacturers. What's so interesting about the review is that not all Flash
drives are created equal. Some have very unique features while some are clearly
better than others. They also took a detailed look
inside one of the drives as well as put two
drives in a RAID-0 array (a la Mac OS X). Now that's cool!"
in a raid array has to be the geekiest thing I've ever heard of. What is this world coming to?
On the playground?
In a raincoat?
I'm just saying...
not always, in my office we share usb drives to save time, so far they're the handiest things i've found so far... but if you really need biomectrically locked drive that looks like an inkpen, go right ahead
The issue of durability and/or reliability wasn't addressed in the review but I have to say that I was impressed as hell when my Cruzer-mini went through both my washer and dryer with no apparent effect. That was several months ago and it still works great.
To ensure perfect aim, shoot first and call whatever you hit the target
Low Speed (1.5Mbps)
Full Speed (12Mbps)
Hi-Speed (480Mbps)
You are in a maze of twisted little posts, all alike.
Gotta love it. Remember this guy. He used USB floppies in pretty much the same manner. I actually emailed him because I was curious about portability(traveling kind). Apparently all the raid information is stored on the drives so the entire raid array could be plugged into another machine and would work with no problems.
NAND Flash is what's making this possible. It's denser and faster than NOR Flash.
If you haven't heard of MRAM, that's definitely another technology to be on the lookout for. According to IBM and Infineon Technologies, it's supposed to start shipping this year.
Basically, it has the density of DRAM, 15ns access time, and doesn't loses it's state even when powered down.
Google turns up some articles: here, here, and here.
Regarding the SanDisk Cruzer Mini, Ars Technica mentions:
Unfortunately, we were unable to ascertain the type and strength of encryption.
Apparently, even the product packaging neglects to mention it. Neither is it listed on SanDisk's website. It could be as simple as rot-13 or as complex as multiple cascading one-way secure pads with quantum elliptical entanglements. Do you dare probe further to figure out what it's doing? Certainly not; you could well violate the DMCA.
Now all we need is a small motherboard, lcd display + keyboard + network card, and we have a nice (cheap?) QUIET portable xterminal.

Conclusion
When we started this review, we only had an inkling of what we might come up with. By the time we finished, our perception that USB drives were a commodity was completely erased. While every USB Flash drive is essentially the same in that they carry data, they are all slightly different and not every drive will meet everyone's needs.
Drive summaries
PNY Attache: As drives go, this one was stylish and sturdy. It comes with a full assortment of accessories, including the USB extension cable and a neck strap. Aside from that, the drive itself is a rather lackluster offering. While much faster than any USB 1.1 device, the read and write speeds are rather slow for Hi-speed USB. The other unfortunate thing about this drive is the lack of extra software outside of the Windows 98 drivers. While it may be possible to find this drive for as little as US$15 to US$20 (after Mail-in-Rebate), it typically goes for US$30+. That is too expensive for such a mediocre drive. --- Score = 5/10
SanDisk Cruzer Mini: Of all the drives in this review, this drive is the thinnest. Some might even call it sexy, but we would not go that far. Unlike most other drives, it does not block dual-stacked USB ports in the slightest. Other positive things include the excellent LED visibility, good read/write scores, and it even works in unpowered USB hubs. Even the CruzerLock encryption software was solid and pretty easy to use. Some complaints would be the lack of a write-protect switch and that the plastic loop for the lanyard is rather weak. (It's fine for hanging around your neck, but it certainly is not load bearing in the least.) That said, the prices found for the 128, 256, and 512MB models make this a good deal. --- Score = 8/10
Mushkin Flashkin: We had mixed feelings about this drive. On one hand it offered a full complement of accessories and features, such as the standard neck strap, USB extension cable, write-protect switch, security software and it even worked in unpowered USB hubs. Yet despite this, everything about the drive felt like it was cheaply made and the security software felt like it was coded as an afterthought. The plastic body was very bulky and felt extremely hollow. On top of this, the slow read/write performance was troubling and the one-year warranty made us wonder how long this drive would last. Overall, the drive is not that bad, but what really lowered the score is that the price for the drive is more expensive than most of the other drives (which are notably better equipped.) --- Score = 6/10
SimpleTech Bonzai Xpress: This drive has the best physical design of the bunch. It is both strong and sturdy, yet still compact and a comfortable to carry. While it does not come with a USB extension, it does have a write-protect switch and some very helpful file synchronization software. What makes this USB drive especially nice is the strong read/write speeds, the solid two-year warranty, and the very nice price (considering how much is included.) --- Score = 9/10
Fujifilm USB Drive 2.0: Two words: speed demon. Without a doubt, this drive is fast! With top read speeds reaching 8.5MB/sec and write performance that destroyed the competition, this drive is perfect for anybody who is impatient or never seems to have enough time. Unfortunately, this drive has its drawbacks. The drive is the largest of the bunch, has no accessories included, no write-protect switch, no low-power support, and a higher price than most. Fortunately, it does come with decent security software and a lifetime warranty. --- Score = 8/10
Verbatim Store 'n' Go: In a nutshell, this drive was consistently above average. Never spectacular, but never terrible either. Read/Write performance is definitely strong, but nothing amazing. It comes equipped with neck strap, USB extension
Well, for those that are interested in the 'bulk' data, you can pickup a 1GB SanDisk Cruzer Mini for only $162 after an instant rebate...

How about fixing USB 1.1 support in Linux first?
USB must be the crappiest kernel subsystem in existence: I can crash 2.4 in a number of ways just by plugging in and removing USB devices. Bug reports are being ignored, sometimes people sugggest moving to 2.6.
Well, 2.6 freezes dead hard when I plug in my USB audio device.
USB is the primary reason for the short (several days) uptime on my laptop.
I've had a 256mb Fuji for 18 months now, and a 8mb DiskOnKey for 2 years before that (the Fuji is a re-branded DiskOnKey drive). The complaints from Ars Technica are only valid if you keep your flash drive on a lanyard. As I can't stand anything hanging off my neck (too much like a tie!), I keep mine clipped to my keyring. I've never had it come unclipped, nor have I lost the drive part (the clip is on the cover, not the drive itself). In fact, having the clip on the cover is very useful, as I can leave it connected to my keyring while the drive is in use.
I'm surprised the review didn't cover performance under GnuPG and PGP -- I keep my keyrings on it, as well as my Quicken backups. Plus tons of room left for mp3s to listen while at work. The SiSoft benchmarks are nice, but I'd like to know how slow/fast they are relative to an IDE drive.

If the cap/lid comes off, there goes your USB Flash HDD! SanDisk and others are smart to put on the Flash drive, not the cap/lid! My 512 GB PNY brand (not the same one in the article) has it on the cap! I don't bother to wear it on my neck anymore since I can lose it easily.

Can you dual boot a bootable USB drive? Sounds like a fun way to waste a few hours....

You'd think this place was run by /. editors or sumptin.
I noticed that some of these flash drives have "write protect". However, I noticed that some manufacturers claim that Linux cannot use the write protect functionality:
" When you put the write-protect switch to "ON" position, you cannot write any file or data into the device. You still can view and read the files and data in the device. You can switch the "Write-Protect" switch even you do not disconnect the device. Due to Linux OS limitation, the write-protect switch will not work on-line."
Flash drive manual
But I see in status messages when people plug in the flash drives that it says "write protect is off".
Does anyone have experience with these products in Linux and whether write protect works with the flash drive connected?

Actually, you're thinking of OSR 2.5 that comes with USB and AGP support.
Win95b (OSR 2.0) only added FAT32 and other minor improvements. It does not support USB without a patch.

We didn't review it for a few reasons.
1) We wanted to focus on USB 2.0 Hi-speed devices (the link you have is for the slower "full speed" - a.k.a USB 1.1)
2) We wanted embedded memory drives only. Upgradable models would have made the article more confusing.
But don't worry, we have a follow-up article in the works that will feature more exotic devices.
As a floppy replacement they are great. I've had mine since the middle of Janurary. My kids have gotten ahold of it a few times and it has survived that I used to carry it in my pocket now I just carry it in my bag it seens to work fine. But here is the thing that you mentioned that is just what it is a a floppy/burning less than 256 meg to a cd replacement. For example I use mine to carry music between work and home. I use it to grab config files off of machines that are on another network/domain. I use it for putting VPN clients on lusers machines that aren't on the network. In short I use it for temporary storage and transfer where doing it that way is faster/easier than doing it over the network. Sometimes I do it just to impress chicks. :) But I would never use it for long term storage of anything I care about and don't have in another spot, they just aren't designed for that. But then again back in the day I know plenty of folks who would do just that with floppies.
:) Count your blessings.
Wish I could get work to buy me another one.

How about selling something like Knoppix on a USB drive? It'd boot faster, fit in your pocket, not need a CDROM drive, allow for customization by being re-writable, and you could keep some of your data files on it. Even better, if you eventually decide that you don't want to use Knoppix, you get a handy USB drive...
You would think that if it's a 256meg drive then you would know the size, 256 megs, right? But marketing has struck again, I've found that 32 meg drivs I have actually seem to have about 30 megs of space on them, and vary by drive. A 64 meg device is also short several megs (as are some flash cards I have). I would have found it really handy if the reviewer had bothered to tell us how much space each of these devices really delivers.
