Question: The external power supply that comes with the box can be use in Asia countries? 240v?
Document: You probably won't see this top speed in most uses, but the relative speed difference would be seen in a given situation. *  I like the form-factor and case, quiet operation, and external power supply. This is a very robust unit for desktop use. *  I found tech support to be friendly, knowledgeable and helpful in resolving my issues.
This drive uses the Seagate ST3000DM001 drive inside. So far the most amazing part is the USB3 speed. It comes with universal power adapter connectors that enable to use it in the 220v countries. One of the most compact 3TB drives you can get if spacing is an issue. So far, it does not run very hot but I have not tested it for 24-hrs straight without turning it off. Has 2 strips of rubber feet so your aluminum casing doesn't get scratched or it does not scrape the contact surface.
I use the small 1 and 2T - they are great. This one is BIG also connected to power supply, not just USB, not as written as 2 credit cardsYou are not getting it from LaCie , but other companyNo return paper suppliedVery confusing return form you should find at internet30% pay for return if openedNot going to use this disk
This little drive is perfect. As soon as I got it, I pulled the actual drive out, which indeed has the same specs as mentioned in other reviews. Put that in my machine and my 1TB in the external. The enclosure itself has great power management and the transfer speeds are outstanding since they use USB 3.0.Cheap, easy 3tb drive and enclosure. I will be buying several more.
This drive lasted only 7 months as a Time Machine backup device on my network. Then, one day I received a notice on my Mac stating that the most recent backup failed. I inspected the drive and observed it was not powered on. I went through various troubleshooting steps including swapping out the power supply and trying the drive on another computer. Nothing would resuscitate my LaCie drive. I exchanged several emails with LaCie support.
I use this drive just store all my music, movies and pictures. The USB 3.0 transfers files quickly, an how it looks on my desk. Great drive that I bought two. I use the other one to back up my work with the easy to use software that comes with the drive. High quality product. A must buy.
Great external backup that's fast.Easy to setup and small footprint for a 3.5&#34; hdd. I use this as a backup for all my computers .
Arrived in well-packed box in good shape. Nice dense packaging by shipper and manufacturer; safe but no wasted space or materials.Easy unboxing, beautiful form factor. A little shorter and less wide than a VHS makes for a great size. Brushed aluminum exterior is a little darker than I imagined but I like it better this way. The power adapter is a little bulky, but for 150$ I'm not complaining!
Mini HD Connect, for which I have a separate review on Amazon.LaCie is a French company and in my experience ALL their products (except for their LaCinema Classic and the Mini HD Connect) have worked smoothly (touch wood). But the problem with their HDD formatting software and documentation which comes bundled on their drives are a disaster, and sadly this happens consistently. I have found the product descriptions on their website to be excellent.
I bought a LaCie Minimus 3TB disk as a replacement for my disk to store backups. The products looks solid and performers very well. Unfortunately it has a major issue that made me exchange it for a WD Elements disk. I'm running an automatic backup in the background and the Minumis disk does not power on automatically, i.e. I have to push the pow button each time which is a nogo for an automatic backup. I talked to support (which is excellent and very responsive even on a Sunday!)
Answer: Yes.  The input is rated at 100-240v, 50-60Hz, 0.5A Max.  AND it even comes with an assortment of interchangeable plugs so that it doesn't need additional adaptors.  To use the entire drive as ONE hard drive (not partitioned) you will need to erase and repartition the 3TB external hard drive with GPT format.  You can find a number of short videos on YouTube on how to do that and it is easy.  These are the best external hard disks that I have ever used.
