Seagate Wireless Plus review: A terabyte of mobile wireless storage

The mobile hard drive lets you wirelessly stream or store your files.

Seagate's Wireless Plus drive -- a follow-on to Seagate's last mobile wireless drive, the Seagate GoFlex Satellite -- is a great idea. Like the GoFlex Satellite, the Seagate Wireless Plus combines a small wireless router with a hard drive, but the Wireless Plus ups the capacity from 500GB to 1TB.

At 0.8 x 3.5 x 5.0 in. and just over 0.5 lb., the Wireless Plus is slightly thicker and heavier than the company's wired mobile drive, the Seagate Backup Plus, but is a bit smaller and lighter than the GoFlex. The Wireless Plus comes in a dark and slick-looking silver matte finish.

Like the Backup Plus, the Wireless Plus has a Universal Storage Module -- a removable SATA interface adapter. It comes standard with a USB 3.0 adapter snapped in, but that can be removed with a quick tug and replaced with a FireWire 800 or Thunderbolt adapter -- if you're willing to part with some additional greenbacks.

The Thunderbolt adapter will run you $99. The FireWire adapter won't be available until the fall, but you can still use the older GoFlex adapter ($24.99) with this drive; it just won't match new drive's look.

Using the Wireless Plus with a computer

You can pack a lot into a 1TB drive: loads of movies, videos, photos or music. In addition, when you're traveling, you can wirelessly upload photos and videos to it.

Like any other external drive, the Wireless Plus shows up as a drive icon on your desktop as well as a drive in your file manager. To upload files to the Wireless Plus from a computer via the provided USB 3.0 cable, you simply drag and drop the files from your Windows PC or Mac. The drive neatly loads the content into the appropriate media folders: videos, photos, music, documents and as well as a catch-all "recent" folder. (And of course the process works the other way, too -- you can download files from the Wireless Plus to a Mac or PC.)

Using the USB 3.0 cable, I tested the drive with Blackmagic Disk Speed Test benchmarking software for Macs. I loaded a 2GB low-definition movie onto the drive in just 20 seconds. Next, I transferred a 1.34GB high-definition music file -- the album Fragile by Yes, which was recorded in the AIFF lossless format. It took just 14 seconds to transfer.

The Wireless Plus drive had a very respectable 115.8MB/sec. write and 126.6MB/sec. read speed -- among the best I've seen for a portable external hard disk drive.

While I'd prefer this drive came with a Thunderbolt cable so that I could take advantage of its 10Gbps speeds, the USB 3.0 that it does come with is wonderfully fast when you've been used to USB 2.0, which is about 10 times slower.

Using the Wi-Fi

The Wireless Plus is limited when it comes to Wi-Fi bandwidth, with only 150Mbps maximum throughput.

If you want to connect the drive wirelessly to a desktop or a laptop computer, you have to access the drive via a Web browser. According to Seagate, the drive should also show as a separate drive on a Mac OS X machine or a Windows system. Unfortunately, I ran into problems connecting to the drive via the website. I was finally able to make the connection after contacting a Seagate technician who gave me the server IP address.

However, even when I was able to transfer files from my Mac, it was slow. Uploading an entire album from my computer to the Wireless Plus looked like it might take as long as half an hour -- it turned out that the drive doesn't like multiple uploads via a wireless connection.

Individual songs were more practical -- a 59MB AIFF audio file from the Yes "Fragile" album took 18 seconds to upload to the drive, while a 297MB AIFF audio file took one minute and 13 seconds.

Bottom line: I don't recommend leaving home without the USB cable if you plan to transfer data to the drive.

The Seagate Wireless Plus management software comes with the drive and runs on both PowerPC and Intel Mac computers using OS X (version 10.5.8 or later); it also runs on computers using Windows XP or later. The software takes up 12.1MB of hard drive space and provides a user interface to help you manage your files.
