At 0.48 ounces, the 8GB SanDisk Ultra Backup is the lightest of the USB drives we recently Sony VGP-BPS13 Battery tested. It's also the least stylish; its all-black design looks a bit dated. At 2.9 inches long, the Ultra Backup stuck out a full finger's width longer than the Lexar MX drive, making it a little more obtrusive when connected to a laptop. Still, it's about the same length as the Patriot Memory Supersonic.

Even if the Ultra Backup looks a bit staid, it has a unique backup button on top that worked remarkably well. Also, an activity light on the drive helps you see what is happening; during backup or file transfer, the light flashes quickly. In a ready state, the light stays Sony VGP-BPS9A/B Battery steady.
Backup Software

The Ultra Backup comes with same Dmailer app that comes with the Lexar MX drive, but it worked well and setup only took five minutes. While you can set the app to automatically back up files, you can also just press the backup button on the drive; it's so easy that you may find yourself clicking the backup button even as you work, Sony VGP-BPS9/B Battery saving the latest version of a Word doc or a recent iTunes download.

One of the unspoken truths of computing is that even power users often forget to do backups Sony VGP-BPS9/S Battery on the road. Yet it only takes one crash to lose your Word documents, photos, music collection, movies, and other locally stored files. The SanDisk Ultra Backup makes this process so easy that you might decide it's time to stop taking your chances.

Performance

Unfortunately, the SanDisk Ultra Backup was the slowest drive Sony VGP-BPS9 Battery of the bunch when it came to copying large amounts of files. When we transferred 5GB of media files and Word documents to the drive, it took a long 8 minutes 41 seconds, which equals a write speed of just 9.8 MBps. That's two and a half minutes longer than the next slowest drive, the Lexar Echo MX (6:08, 13.9 MBps). If you're looking for fast transfers, the USB 3.0-powered Patriot Memory Supersonic blows all of these drives away with a write speed of 41.3 MBps.

Likewise, copying those same files from the SanDisk to a notebook took 4:45 (a read speed of 18 MBps), about 40 seconds Sony VGP-BPS13A/Q Battery longer than the next slowest drive, the Imation Defender F200 (4:07, 20.7 MBps). The Patriot Memory drive took just 55 seconds, a rate of 93.1 MBps.
Pricing

The Lexar Echo MX is one of the more innovative USB drives we've tested. The main reason: There is a Sony VGP-BPS13A/B Battery small gauge that shows the capacity level, even when the 128GB device is not plugged in. An included backup program, free 2GB of online storage, and speedy operation make the pricey Echo MX ($500) an option worth considering for those who need a lot of capacity in a tiny package. Read on to find out how this drive Sony VGP-BPS13/B Battery performs.
Design

Measuring just 2.6 inches long, the Echo MX is the smallest drive we tested, but we had to wonder Sony VGP-BPS13B/B Battery about its construction. When the idea is to rely on this drive for backups, you want to make sure it holds up to abuse. Weighing 0.96 ounces, the MX's all-black plastic build felt a bit cheap compared to the Patriot Memory Supersonic and the Imation Defender F200, both of which have metal cases. A thin strip along the top that looks like an E Ink display fills up as you load the Echo MX with your files, which helps this drive stand out.
Backup Software

Not only does the 8GB SanDisk Drive offer a relatively Sony VGP-BPS13B/Q Battery small amount of storage space, but it also doesn't offer the best value. The 8GB version we tested normally retails for $45, but was on sale for $30. That's $3.75 per GB, which isn't bad, but the Patriot Memory drive costs $210 for 64GB, which comes to $3.30 per GB. SanDisk also offers the drive in a 64GB capacity for $202, which gives you the best value. There are also 16GB ($75) and 32GB ($113) versions available.
Verdict

While its transfer speeds aren't great, we love the simplicity of copying files to the SanDisk Ultra Backup. Sony VGP-BPS13A/S Battery Sometimes, that's all that matters.

The Echo MX drive includes the same Dmailer backup program that comes with the SanDisk Ultra Backup USB drive. Setting up the drive took less than five minutes, since the software is so easy to install and configure. The software has 128-bit AES encryption and automatically backs up Sony VGP-BPS13/Q Battery files.

There is one extra step with the Echo MX, since you have to create an account on the Dmailer service for online backups. While this OEM service has its own website (www.dmailer.com), you can't login directly from its website; you have to go through the backup app. That means Sony VGP-BPS8 Battery you can't check your online backup from any computer unless you install Echo Backup first. The 2GB of online backup is free, but a more useful capacity of 30GB costs $35 per year.

The main issue we had with the Lexar Echo MX was not the speed or software, but the price. The 128GB drive we tested costs $500--$3.90 per GB--but the 8GB version is also a bit expensive, at $45. (The Echo MX is also available in 16, 32, and 64GB capacities.) By comparison, the 64GB Patriot Memory Supersonic costs $210, Sony VGP-BPS8A Battery which is just $3.30 per GB.
Verdict

We like the Lexar Echo MX's read and write speeds, its intuitive backup software, and 2GB of online storage. However, for the amount of money the Echo MX costs, we wish it felt more durable. Still, its fuel gauge is a decided benefit to anyone who wants to know at a glance just how much free space they Sony VGP-BPS21A/B Battery have.

Performance

Among the USB 2.0 thumb drives we tested, the Lexar Echo MX Sony VGP-BPS21/S Battery drive was one of the fastest. Copying 5GB of files (including a 2GB HD movie) to the drive took 6 minutes 8 seconds, a rate of 13.9 MBps. That's about 20 seconds slower than the Imation Defender F200 (14.8MBps) but more than two minutes faster than the SanDisk Ultra Backup (9.8 MBps).

Copying the files back to our laptop took 3 minutes 30 seconds, a rate of 24.4MBps, which beat out the SanDisk (18MBps) and the Imation (20.7MBps) by a fair margin. Still, it took the USB 3.0-enabled Patriot Memory Supersonic drive just 2:04 to write those files, and just 55 seconds to pull them Sony VGP-BPS21 Battery off.
