This review is for the US$69.99 320GB Seagate GoFlex Ultra-Portable USB 2.0 plug-and-play drive, not the 500GB model as the header suggests. (Price was from Amazon USA)

I'm running XP Home with SP3 on an Intel Core2 Quad Q9550 @ 2.83GHz with 3.21GB of DDR2 RAM.

This drive comes in a very nice small package and implements easily into your system. XP recognized the drive and it appeared as accessible within 10 seconds of being plugged in. Now, if you don't need all the back-up software, your drive is ready to use. I copied my "MY DOCUMENTS" folder onto the drive with no issues.

I then installed all the programs the drive comes with under the "Seagate Dashboard Setup", including the Memeo Back-up, Memeo Sync, Memeo Share and Memeo Send. Installation was quick and I checked out the back-up utility to see if I could get just my My Documents folder to back-up every 30 days. I found the software to be fairly easy to use and was able to remove the backing up of the entire C drive and the Outlook settings and replace the folders to back-up with just My Documents. I have 2 1TB drives running in RAID1 for all my music and video so I really only wanted an additional drive to keep My Documents backed up which is where my pictures and executable software files remain so I don't have to go searching for them whenever I reformat my hard drive, which is really the only decent way to speed up your PC's performance and clean out the registry.

Anyway, the software worked well, I haven't used it long enough yet to determine how much of a memory hog it is, but if it's not processor intensive then I'd have to say it's worth the money you pay for it and with the included software makes a nice package.

Clearly those backing up lots of movies, etc., may wish to consider looking at a 2TB configuration.

The most in-flexible piece of junk I have ever purchased. I purchased the 750 Gig unit and you have absolutely no control over what goes into the damn thing. Once its filled, its filled, you can't replace it with new data. Would never by another Seagate product. Stay away.

Really great, bought this a year ago and I have nothing to complain about. Works really great with a Mac, not so well with a PC, making back-ups was complicated and worked half the time. I suggest you look for something else if you want to use it on a PC.

HASH(0xa11c70c0) out of 5 stars Format this drive first to avoid issues with this drive!! March 4 2011
By lasfk - Published on
Verified Purchase
I was expecting this drive to be like a spare drive to back up files and store data on and allow me to edit some files as I wanted. I really was expecting it to work just like a jump drive does, but have a lot more storage space. I didn't want to have to plug it into a wall, you know, portable. I wanted to be able to take it to several computers I have at home and at work. What I found out after I placed my order was that these drives by Seagate have pre-installed software on them that once connected to your computer will ask you to load, after a two minute wait. If you install this software "Dashboard" and whatever else is there, you may have some of the issues like all of the other negative ones I read. YOU DON'T NEED THIS SOFTWARE, SO DO NOT INSTALL IT!!! Seagate must think that the only purpose to buy this drive is to do a back-up on one computer and to have it auto run every so often, hence their software. I personnaly am not interested in their software, especially everything I have read to date on it.

So I started by removing the software from the drive, then just using the drive as a back up and to copy some work files to. All seemed fine, then took to work and tried to update a file and found out the the whole drive is read only format, no update capabilities allowed from another machine. Did some more reading and discovered that if I Format the drive completly, (don't do the quick format) do a full format which will take about 1 hour per 100 Gig, so make sure you have plenty of time to do this. When your done the drive will be free of Seagate's software and read only formats for file updates. The drive will work just like a jump drive allowing you to take it from one computer to another, update files as you see fit, back up files and so get the picture.

I think if Seagate wants to keep their good name, they need to offer better instructions on their products and they should not pre-load this software on their drives. All of the issue, at least most of them, appear to be with this software and not really the drive itself. At least this is my finding after I performed this format, the drive is now what I expected to use it for.

So for a rating, out of the box, I give it a 1 STAR, because I had to figure this out, and spend 5+ hours to format the drive.

Rating after the format, I give it 5 STARS!

I hope others find this review helpful, as I am a little tech savy, but no comparison to most of you smart people out there.

HASH(0xa11c7360) out of 5 stars Good drive, potentially misleading claim June 7 2010
By Mark Colan - Published on
Vine Customer Review of Free Product
This drive has a large capacity (by today's standards) and is very portable. It is convenient and highly compatible, not fast, but no slower than others in its class.

I seriously doubt the claim that buying a USB 3.0 adapter for the drive will speed it up noticeably, and certainly not 10x. I discuss this point below. [Update 8/10/10] See below. A discussion in the comments has convinced me that the optional adapters may indeed make a difference for transferring very large files, such as video, but not a 10x difference.

large capacity for portable drive by today's standards
small and not too heavy, similar to competitive products
USB 2.0 offers terrific compatibility (Win, Mac, Linux when drivers are available)
alternative interfaces available (eSATA, USB3, Firewire)
USB provides power, so no power supply needed
very standard USB connectors on both ends of cable
compatible with Windows and Mac, and probably Linux (not tested)
[Update] ability to connect directly to TV for playing audio and video without computer via new dock [see below.]

misleading claims of value of changing cables [Update: maybe not, see Updates below]
slightly larger and heavier than WD Passport
glossy top attracts fingertips (like Passport)
black case is hard to find in my black computer backpack, but probably other colors will be available in the near future

not fast, not slow, about the same as competitive products, slower than desktop drive or many 3.5" external drives, but far more portable


The drive spins at 5400 rpm. This is not as fast as most desktop drives (which are 7200 rpm), but 5400 rpm saves power and runs cooler. It could be that 7200 RPM drives could not be used for an application like this without a power supply. Big drives make great archives, and archive drives don't need to be as fast as the drives that contain your system, programs, and files you are working on.

I copied my audio collection - over 50,000 files totaling 383 GB - to this drive, starting empty, and (separately) to an empty 500 GB WD Passport drive that had been freshly formatted. Both drives took about the same amount of time: a bit under 7 hours, with Windows 7 reporting 16-18 MB/second. The Passport was a little faster, but not enough to make a difference.


The included "Personality Cable" allows this drive to be used with USB 2.0. You can get others for USB 3.0 and eSATA, and they CLAIM that this will speed performance by up to 10x. I haven't tried to be certain, but I sincerely doubt that this is true.

You see, USB 2.0 is capable of 57 MB/sec, yet my drive runs at 16-17 MB/sec, so it is performing at only 29% of the maximum USB 2.0 speed. I think the disk itself is the limiting factor. Although eSATA and USB 3.0 are faster interfaces, they can't make a 5400 RPM drive go 10x faster. By comparison, copying files from my internal 7200 rpm drive to an internal 10,000 rpm drive with direct SATA interface maxes out at 66-70 MB/sec, which is about 4x the speed.

By analogy, your car may be capable of 100 mph, but on a lot of roads you're only going to be able to go 25 mph. Putting a faster engine in the car won't help. In this analogy, the disk is the road, and the interface is the car.

Many manufacturers have been very misleading about disk speeds. They often rate the performance as that of the interface, when the device itself is significantly slower. The ONLY time any drive reaches the interface speed is when the data you wanted is already in the cache - that is, you just read it or wrote it, and now you're reading it again. Because the cache is tiny compared to the disk capacity, this is an uncommon situation.

In summary, I doubt the optional interfaces are worth buying.

UPDATE 8/10/10: This section triggered considerable and interesting debate in the comments, and I stand corrected. The upshot is that when transferring "smaller" files (jpg's, mp3's), the transfer rate may be limited by drive performance, but for "large" files (video files, say ~200 MB and larger), sustained reads may indeed mean that the drive is pumping out data faster than the interface, and using a faster interface such as firewire or USB3 could improve performance for transferring large files.

Also, I ordered an eSATA interface kit. For a system with SATA drives, I suspect this interface will be faster than Firewire or USB3, but I'm guessing. I will run some new tests and probably rewrite this review with the results.


UPDATE 8/10/10: This is a cool innovation. A dock for this hard drive, which you connect to your TV to allow playback of photos, audio (including SPDIF digital audio), and video (including HD), is now available. See: Seagate FreeAgent Theater+1080P HD Media Player STCEA201-RK. That dock would be handy for people who don't have a computer connected to their home entertainment system but want to play back their media library there.


This is the most important feature, and only time will tell. New drives rarely have any problems, and I saw none. The drive has a 3-year warranty, less than some. *Many* years ago I had a Seagate drive fail and I lost data, and I have always held a grudge. With massive changes in technology and manufacturing, this grudge amounts to superstition, but I still normally prefer WD, because they have never failed me.

UPDATE 11 Feb 2011: I started experiencing some serious problems with the drive, amounting to USB failures. At times it would not be recognized; sometimes Windows said it needed to be reformatted; sometimes it did not appear at all; in all cases there were times that I could not access files, and later I could. Then I noticed that I was using a cable that was not the one that shipped with it, but was plug compatible. Now I'm using the original cable. So far, none of these errors. I'll update again if that changes. Lesson: not all USB cables are created equal, even when they are plug compatible.


Early drives are always boring black, and they are hard to find in a black computer bag. The comparison drive I used was a red Passport, which is easy to find, and I like the color.

The case is slightly longer than the Passport 1TB, and the drive is a little heavier 9.9 oz vs 7 oz for Passport 1TB, or 41% heavier) , according to the manufacturer's specs.


1 TB is currently the largest size for this kind of disk. Starting with the 250 GB drive, these drives have started at the same price when new, and then decrease as larger ones come out, which is a good thing for consumers. Now we get 4x the capacity of the original 250GB drive for the same price.


Drives like this are now commodity items, with little to differentiate them aside from their size, so you can choose based on color/style or price. Seagate is a name brand and the drive should last. The WD Passport is somewhat lighter, slightly smaller, very slightly faster, and a little more expensive. The product is very good but does not excel, hence 4 stars.

UPDATE: My claim that the drive works for Mac is based on what Seagate says; I did not test that. I have read in other reviews people who have said that it did not work for their Mac. In one case, the review said he was running OS X 10.3.x. Someone suggested that this drive is said to require a later version of OS X, like 10.4.6(?). Please note: I am not a Mac user and my memory of OS X version numbers is not exact. The point is, Mac users might have more luck when the latest OS is installed.

DISCLOSURE: This product was provided to me by Amazon free of charge in return for a review. All of my reviews are written honestly - exactly as I see them.

HASH(0xa11c7c84) out of 5 stars Failed Within a Month Sept. 3 2010
By Matt W. - Published on
I've had my eye open for one of these since before they existed. I work in the Multimedia industry and require a large amount of space to store my data. I purchased this drive on August 8, 2010. Yesterday, Sept. 2, 2010, it failed. I contacted Seagate and they referred me to their data recovery team who offered to recover my lost data for up to $1500. Not expecting to have the hard drive fail immediately, I was still in the process of backing up my files and lost almost all of them.

HASH(0xa11c775c) out of 5 stars Superior portability and design April 26 2010
By ConsumerAdvocate (dakotad555) at (gmail) dot (com) - Published on
Vine Customer Review of Free Product
The design of this external drive is excellent. The enclosure itself is tiny, just a centimeter longer and about a half centimeter wider than the 2.5" 500gb hard drive it houses. It is made of piano-black plastic that is matte on the bottom (to prevent it from sliding around as well as to avoid scratches) and shiny on the top and sides. This is actually my only complaint with the device: these days it seems like every peripheral device needs to be polished, and these surfaces are finger print magnets. I blame Apple for making their wildly popular i-Pods shiny. I prefer matte surfaces that absorb use better and don't need to be polished constantly.

Functionally the drive is excellent. The hard drive included is a slower 5400rpm drive, but for a back-up drive that's adequate. It also allows the use of a single USB connection for data and power, unlike many other portables that need two connections to function properly. Windows 7 immediately recognized the drive and installed the appropriate drivers. There is a proprietary back-up software that comes with the drive which I did not spend much time messing around with simply because I intend to use the drive as media storage for my notebook, not as a back-up solution.

Where things really get interesting is in the design of the enclosure, which has a separate USB connector piece that plugs directly into the SATA connectors of the hard drive itself. This allows for you to swap out the connector once USB 3.0 is released, or even a eSATA connector if Seagate releases one (this drive is too new to be on their web-page but I can only assume they will release one). It also allows for you to dock the drive in a Seagate hard drive dock. This open-ended design is fantastic and I'm surprised it's not available on more external drives. I suspect Western Digital will soon follow suit with their portable drives, as this is a much appreciated improvement.

The provided USB cable is a bit short. Thankfully, it is a standard mini(b)-usb connector so you can easily swap the short cable out for a longer one like this one. Thank you Seagate for not using some proprietary connector type.

I've always been a fan of Seagate hard drives and use them in most of the system builds that I've assembled in the last few years. The only issue I ever had with their drives was with a pair of 500gb 7200.11 drives which began to fail (both failed the SMART test). Seagate replaced both of them through their RMA process quickly and painlessly--earning my repeat business in the process.

The warranty is for 2 years for the hard drive and 1 year for the other parts. This isn't as good as WD dries which have a 5 year warranty.


1) Small form factor

2) Only requires 1 USB connection

3) Novel design allows for forward compatibility with USB 3.0, as well as a hard drive docking stations, and potentially eSata connections

4) Aesthetics are great

5) Seagate makes good hard drives (and backs them up with good customer service)


1) Shiny finish is a fingerprint magnet

2) USB cable provided is only about 18 inches long

3) Warranty is only 2 years (standard warranty on hard drives is usually 5)

Final Thoughts:

This truly is a portable drive. It's very small, light, and only requires a single USB connection. It's a wonderful option for a back-up drive as well as for extending the storage of your notebook.

Okay. I'm in love. I was expecting a huge package with a drive needing an external power supply as well as a USB cord. Nope.

This is a 1TB external hard drive that is truly portable, and powered with only a USB cord. So you don't have to plug this external drive into a wall socket to use it. Installation was as simple as plugging the USB cable into a slot on my computer. No software, no extra work, just plug and go.

My one very minor complaint - software designed to be used as a backup shouldn't have been the default installation choice, because in order to use the software you have to pay a monthly or annual subscription fee, after of course, a brief 'free trial.' This feature really should be turned off by default.

The drive worked flawlessly on a test run, copying files from my hard drive to the Seagate FreeAgent. Everything works as expected, and I recommend this product.

Update after first 24 hours of use:

I still love this drive and consider it a great product, but I do agree with the other reviewers who suggest this item isn't really designed for permanent use as a backup drive. I'd use the drive on the go, switching back and forth between a laptop and a desktop, but if you're looking for high-quality continuous storage, look for a heavier drive with a power supply.

My 500 GB external drive that plugs into the wall has a much faster copying/reading/writing speed than this Seagate GoFlex. Because the GoFlex is powered only by a USB cable and no external power source, it will be by design far slower than a high-powered drive. This shouldn't matter for the needs of most users, however, I wouldn't necessarily recommend this Seagate Goflex for a corporate or heavily demanding computing environment.

Update after several months of use:

I am using this 1 TB hard drive daily to back up files, and completely forgetting its 'only' powered by USB, without an external power supply, and the drive has worked perfectly. I did use double-sided foam tape to fasten the drive to the top of my computer - this hard drive has such a small profile, it would be easy to accidentally knock it off the top of the computer.

Specifically, I have a huge music collection, and I've just 'ripped' the last music CD I own to this external hard drive, so I can put away the original CDs in a safe place. This 1 TB drive hasn't even belched or wheezed and it's nicely holding 70 DAYS worth of music CDs and other backed-up audio content. Even at 220 GB, that isn't enough data to fill a quarter of the storage space on this gorgeous 1 TB hard drive. Highly recommended? You bet.
