Following the top model with 1GB of memory capacity, we have also now taken a look HP Compaq 2133 Akku at Seagates' 320 GB variant with the innovative Auto Backup feature. Find out which differences and which advantages we uncovered in the following review.

With a new interface concept, the VGP-BPS9/B GoFlex series from Seagate offers a wide spectrum of possibilities for interface compatibility. With the optional adaptor, one has the possibility of ordering the individual required interfaces as need be and using the series with multiple harddrives. We already reported on how this works in our comprehensive review of the Seagate FreeAgent GoFlex Ultraportable 1 TB.

The case of the 320 GB version is slightly lower at 14 mm and somewhat lighter at 150g than the larger model. But the case VGP-BPS9A/B texture, with its high-maintenance glossy black paint job, is identical and doesn't always go down well with mobile use. We also elaborated more on that issue in the review mentioned above.

Seagate FreeAgent GoFlex Ultraportable 320 GB

In the performance tests, we have again tested the available interface adapter VGP-BPS9 and accompanying harddrive on different desktops and notebooks. USB 2.0, eSATA and USB 3.0.

The Lenovo Thinkpad W701 was available for the eSATA test, which fortunately is equipped with a powered USB / eSATA combination port. This is necessary to ensure the GoFlex harddrive's power supply, as an additional alternative power VGP-BPS9/S supply is not provided. This worked well and without any problems in our tests, and LED to a maximum transfer rate of 78.6 MB/s on our testing device (internal Seagate ST9320423AS min, 16 MB Cache, 7200 rpm). But, in the same testing scenario, we got only 96.1 MB/s with a LaCie d2 Quadra which suggests that the GoFlex adapter slows down the built-in harddrive somewhat. For a performance comparison, refer to our extensive HDD benchmark list.

This 'braking' we noticed in the test was not apparent with the installed USB 3.0 adapter, which extended the performance of the Seagate with a maximum of 93.1 MB/s and an average of 75.5 MB without loss. This also highlights the difference in performance to the bigger 1 TB GoFlex, which reached a maximum of 87 Studio 17 Battery MB/s and an average of 65.2 MB/s. We also didn't observe any problems with the power supply on the tester and provides the model with a broad spectrum of possibilities.

The transfer rates on the USB 2.0's of various testers were at a maximum of 30.7 MB/s, though Studio 1737 Battery many notebook interfaces are unable to deliver those speeds. The HP 6540b Probook for example went on strike at 28.1 MB/s, which is still in the normal range. Otherwise, only a few notebooks and desktop systems could reach over 30 MB/s.

Verdict GoFlex 320 GB

Overall, the Free Agent Portable 320 GB Studio 1535 Battery Ultra GoFlex offers the same good qualities as the larger 1 GB version. Even the entry level model scores points in terms of its weight, size, and USB 3.0 speed. It doesn’t look so good with the euro-per-terabyte ratio, which obviously accounts for the seemingly low cost of 200 euro/TB. The 500 GB und 750 GB versions are significantly cheaper at approximately 140,- euro/ TB, but they don’t measure up to speed as the 1 TB GoFlex which is less than 130,- euro/ TB.

Seagate FreeAgent GoFlex Auto Backup

The last feature we looked at in this test was the Auto Backup function. While there is a backup program (Memeo) on every GoFlex VGP-BPS13B/Q Ultra Portable, this only covers basic needs and is operated by familiar procedures. In turn, we would definitely expect the available extension, which at its core represents a special USB 2.0 adapter, to be more user-friendly. This add-on device is currently available for about 20, - euro and apart from its slightly larger design, is similar to the other interface enhancements in the GoFlex series.

Seagate uses a backup software program called Replica, which impressed us good battery with its simplicity. The initial installation is carried out with only the adapter and without a connected harddrive, which in turn contains the software. Once this process is completed, you are then instructed to connect the driver. Replica works as a background device and shortly after its installation, it does a complete backup (1:1 copy), including all open files. This process lasted around 2.5 hours on our test system with 90 GB of full space. Some secure partitions could already be accessed while the other partitions were still being processed. After the backup is made and when it is again connected, only those changes made in the snapshot method (older and younger versions of changed data side by side) are, also automatically, saved. For example, when creating the backup, we continued to work on this review and later found the three corresponding snapshots. If any activities are stopped, Replica picks up where it left off and continues with its tasks.

In case something gets lost or a file gets damaged, it is possible battery to restore the files by simply dragging the chosen file from the backup. If the backup at some point gets too full, the older files are automatically deleted. Hopefully it will never crash, however, if that does happen, Seagate provides a recovery CD (made by a Linux system). With the help of this, it should be able to restore the whole system. But we didn't test this feature.

Verdict GoFlex Auto Backup

The backup resolution provided by Seagate is perfect for solid “backup muffle” which are running out of excuses. Even diligent users can enjoy its simplicity which now makes the task of backing up files a minor matter. Plugging in a single cable into the USB port is all that is needed! The rest is done automatically batteries for you. It doesn't get much easier than that.
