Many 320 GB hard drives found in current laptops are considerably slower. This is a respectable result given the size and memory capacity of the drive. With a USB 3.0 adaptor attached, we could fully utilize the power of the Seagate ST91000430AS with the MSI motherboard, achieving a maximum transfer rate of 87 MB/s and an average of 67.7 MB/s. The power supply was very reliable here, both with the laptops and the desktop PC. These are normal levels for USB 2.0, which however are rarely reached by notebooks. With the USB 2.0 cable, which comes with every 2.5-inch GoFlex, we measured a maximum data transfer rate of 30.8 MB/s and an average transfer rate of 29.3 MB/s. So we could not establish any exact specifications for it other than its 16 MB cache. We identified it as the ST91000430AS, which cannot be bought separately yet in this country. We also used a USB 3.0 ExpressCard/34 from Raidsonic.Īs you would expect, Seagate has used one of its own-brand drives in the 2.5-inch FreeAgent GoFlex Ultra-portable case. We tested the ports on different notebooks (HP ProBook 6545b, HP Mini 5101, Lenovo Thinkpad W701) and a desktop computer with an MSI 880GMA-E45 motherboard (only USB 2.0 and USB 3.0). However, we will examine the USB 2.0 auto-backup function in our test of the 320 GB version which is shortly to follow, and the Gigabit LAN docking station will also be covered in a separate report. We had all types of adaptor cable available for our testing except for FireWire 800. The cable are around 43 cm in length which is about standard for mobile 2.5-inch hard drives. Two embedded status LEDs indicate hard drive activity and connectivity. A firm connection is made by the port itself and the shape of the adaptor, with no need for slides or buttons. This gives you confidence in the longevity of the product and allows you to plug and unplug things very easily from the case. Firstly the ports on the back are relatively well protected, and secondly the adaptor cables are very robust and provide a secure grip. We like the fundamentals of the GoFlex series.
The 1 TB model is slightly taller than the others (with a 12.5mm tall hard drive), but its dimensions are within the usual range at 134 mm (L) x 89 mm (W) x 22 mm (H). Seagate lists a weight of 280g for our 1 TB test model (hard drive only), while we measured 300g including the adaptor cable. They would have done a much better job of preventing slippage on smooth surfaces. We were also unhappy with the lack of rubber feet on the roughened underside of the drive casing. The disadvantage of this finish is that it quickly gets covered in fingerprints, dust and tiny scratches even if you try to be very careful with it. Only the 500 GB version is currently available in all the colours, while the 320 GB version is available in silver, and the 750 GB and 1 TB models are currently only available in a high-gloss black like our review model. The drives are available in four different colours, black, red, blue and silver. The main disadvantage: with this system you are tied to only using Seagate hard drives. Depending on your needs, this system could be a bit more expensive than a conventional solution but if you have several hard drives the system would quickly become more economical. So you can get just the specific ports that you need, and use them on any FreeAgent GoFlex Ultra-portable hard drive. For external use, Seagate has designed a sophisticated system of adaptors, based on the ports mentioned above.Ī USB 2.0 adaptor cable is included in the standard boxed set, and you add to this as required by purchasing adaptors for eSATA (power eSATA with a power supply via USB), FireWire 800, USB 3.0, USB 2.0 auto-backup version or a Gigabit LAN dock. The cases will now feature a power supply and Sata port, as you would get on an internal hard drive this means that you could theoretically use them inside a desktop computer. But Seagate has now come up with a new approach, which starts off with the lowest common denominator. You have to decide what type of connection best suits your needs, or pay a higher price to have several different ports in one device. Traditionally, when you buy an external hard drive you are limited to one or more specific ports which are built in.
