First of all, you need to know that Seagate Expansion have two different looking models. The first one was launched in 2012 (Old 2TB model STBX2000401) in four capacities – 500GB; 1TB; 1.5TB and 2TB. The biggest capacity of 2TB was quite a lot for an external portable hard drive back then. Seagate Expansion gained popularity and it still is until now, so in 2015 Seagate launched new model of Expansion (New 1tb model STEA1000400). It looks different but have the best from Expansion series, which is big capacity and low price. New model comes in five capacities – 500GB; 1TB; 2TB; 3TB and 4TB.

Design – Nice and simple, isn`t a typical portable hard drive design enough?

We saw impressive design update in Expansion series this year. Seagate Expansion still comes only in one color and it is Black for both new and old model. The new model (STEA4000400, 4.6 x 3.1 x 0.6 inches) has become a little bit smaller than the old one (STBX2000401, 4.8 x 3.2 x 0.6 inches). On the inside it has standard 2.5-inch hard drive. Small size makes the drive very portable and you can easily take it with you. Which is great for photographers and people who are always on hurry. But product weight haven`t changed at all – 5.9 ounces and shipping weight from Amazon will be about 10-12 ounces.

Both new and old models are almost identical. They both have USB 3.0 port which is now standart for most external hard drives. Both models are backwards compatible with USB 2.0 ports, which can be useful only if you work with very old computers.

Expansions package includes a foot long micro-usb 3.0 cable, the shorter the cable, the better. Like almost all portable portable hard drives Expansion is Bus-powered, it means that drive powers via usb cable. One cable for both power and data transfer.

Out of the box Seagate Expansion will work on Windows, because it is formatted in NTFS file system. The hardware will be automatically recognized by the Windows operating system, and users do not have to install any softwares or drivers. To copy files to hdd simply drag and drop them, easy as that. For maximal energy efficiency there is built in power management system, which automatically configures to save energy.

In order to use it with Mac you need to reformat it into HFS+ file system, it will be definitely much cheaper than buying Mac-Designed portable drive. It may hurt some feelings, but everything that is “especially” made for Mac is more expensive than other products.

What to do if you need to work on both Windows and Mac? No problem! All you need  to do is just format the drive into exFAT file system which will work on both OS. You can also use it with game consoles like Xbox and PlayStation, just remember to reformat the drive in supported file system. Personally i use Expansion for Xbox One to save games, the drive get`s recognized quickly and overall i`m very satisfied.

Use it with game consoles like Xbox one or Play Station 3

The 2.5 inch drive inside spins at 5400RPM instead of 7200RPM like many other portable drives. Slower RPM means slower performance, which is hard to say about Seagate Expansion. But slower RPM also means lower power consumption.

The 5400RPM hard drive uses less power than 7200RPM, slower hard drives are more economical

No bundled backup software included

Seagate Expansion unlike many other Seagate external hard drives comes with no software. Be carefull when traveling because your drive won`t have password protection. You still can use Seagate Expansion as backup drive with any other third party backup software on Windows. To use it with time machine all you need to do is reformat it to HFS+ file system.

Seagate Expansion – Performance

When compared to other low-power portable hard drives Seagate Expansion shows good speeds via USB 3.0 port. The drive sustained writing speed of 119Mb/s and 130Mb/s for reading. Drives that are faster than Seagate Expansion use speed-boosting features such as RAID0 or they are SSD portable drives. It is faster than loved WD My Passport Ultra which read/write speeds are both under 120Mb/s. Also, Seagate Backup Plus, Seagate Slim, WD Elements are much slower than Seagate Expansion. Toshiba Canvio Slim II is a runner up with read and write speeds both very similar 118Mb/s. With USB 2.0 speed is 30Mb/s because USB 2.0 port can`t perform faster than that.
The drive is very quiet and stayed cool while tested with a 10GB test file few times.

Final thoughts about Seagate Expansion

Without sophisticated features Seagate Expansion can be very simple, easy to use and cheap external hard drive. Who isn`t looking for a storage that is cheap, fast, easy to use and have a big capacity? It is a great hard drive for Windows and Mac users, gamers, photographers and home users.

You need to look for other external hard drive if many sophisticated features are really important to you, otherwise it would be just waste of your money. However if data protection against unwanted access is your primary goal then you should look at Backup Plus Slim or WD My Passport Slim. Both of them allows password protection and are very affordable.
