I've purchased a lot of different hard drives over the years and used to build my own external drives using internal drives and external enclosures. It used to be cheaper to build your own external drives. These days, external hard drives are very competitively priced, like the Seagate Expansion drive.

- Quiet
- Stays cool
- Fast USB 3.0 performance
- Backwards compatible with USB 2.0
- Works with Mac OS X 10.4.8 and up

- Measly 1 year warranty

The Seagate Expansion portable hard drive's enclosure is made out of matte plastic that feels pretty well made, though I'd prefer aluminum for durability and better heat dissipation. Glossy plastic enclosures are hard to keep looking good, so kudos to Seagate for using the matte plastic instead. The back of the drive has the USB 3.0 port and there's an itty bitty blue power/activity light on top of the drive, towards the back. Also, there are small rubber feet on the bottom, to keep the drive from sliding around on your desk. The USB 3.0 cable is short, so it's best suited for use with laptops.

CrystalDiskInfo identified the internal drive as a Seagate Momentus Thin ST500LT012, which is a SATA II (3Gb/s) drive with a 16MB cache. It has a height of 7mm and runs at 5400RPM. 5400 RPM drives are the standard for portable external hard drives because they don't run as hot as 7200 RPM drives. 5400 RPM drives are perfectly suitable as storage drives.

I tested the Seagate Expansion drive over USB 3.0 with CrystalDiskMark and got sequential read/write rates of 107MB/s read and 105MB/s write. That's likely about 3 times the rate of what you'd get over USB 2.0. So yes, the Seagate Expansion USB 3.

Size: 1 TB
I also have the big brother version of this drive (3TB external hdd, AC powered), and both were very easy to use, plug to the USB port, and then start transferring files.

This is the portable version, which means no addition AC power supply needed, everything is powered by USB. Portable also means smaller compared to the AC powered external HDDs. Maximum capacity for portable HDDs right now is 1TB compared to 3TB for AC powered external HDDs.

Besides media files, this is also perfect for backups, documents, etc., and if you have a laptop equipped with SSD, you'll gonna need more space and this is perfect.

So far so good, no problems at all. Used it on my old HP laptop with usb 2.0 port, works good (slower transfer speed of course). Used it on an alienware m14x with usb 3.0 port, works good again and now with fast transfer speed. Used it on my LG 3dtv to watch full hd movies saved on the drive and it works great! I hope it stays like that, can't comment on the reliability yet..

Warranty: Only 1 YEAR. Why did Seagate shorten the warranty? I have no idea.. If you want other drives with longer warranty, here's some options:
Seagate Backup Plus 1 TB USB 3.0 Portable External Hard Drive STBU1000101 (Silver)
Western Digital My Passport 1 TB USB 3.0 Portable Hard Drive - WDBBEP0010BBK-NESN (Black)

- Portable, no external power supply needed
- Maximum capacity of 1Tb for portable drives (as of now..)
- Matte casing, so its not prone to scratching and fingerprints
- Fast usb 3.

Size: 1 TB Vine Customer Review of Free Product ( What's this? )
An external hard drive like this Seagate Expansion 1 TB USB 3.0 Portable External Hard Drive (STBX1000101) is about as good a backup drive and portable solution as you can find. It's compact, very portable, and for those still using computers with USB 2.0 ports, it's a forward-looking device for when a computer with USB 3.0 is in the plans. But first, here are the basics...


+ Compact and sturdy; measures about 3½" wide x 4¾" long x ¾"high
+ USB 3.0; can be used with USB 2.0 computers
+ Works with Windows PCs (Vista or higher) and Macs (O SX 10.4.8 or higher)
+ Easy plug-and-play setup on both Mac OS and Windows systems
+ 1 TB (terabyte) capacity; about 930 Gb useable space formatted
+ Runs quietly; offers excellent performance
+ Reasonably priced; excellent bang-for-the-buck


- No password protection, but this may not matter to many

First Impressions:

Packaging is very straightforward, as it comes in a box that's easy to open. Inside is the expansion drive, a USB cable, a simple IKEA-style quick setup sheet and a warranty statement (see note below). Looking at the drive itself, its semi-matte black case has a metal-shielded top over a rigid plastic base, and measures all of 3½"W x 4¾"L x ½"D, and it weighs less than 5¾ ounces. On the back is a USB 3.0 port, and it comes with an 18" USB cable that plugs into the USB 2.0/3.0 ports on the computer.

In Use:

We all have differing reasons for purchasing and using external drives like this.
