Toshiba 3TB Canvio Desktop External Hard Drive (Black)

I bought two of these disks on april 1th 2016. I paid super cheap, $135 for the 5TB model because amazon had a sale. Arrived on time (I do not remember receiving myself a late amazon deliver). Worked fine. The disk is so big that it needs to be connected to an electrical current outlet. An Alternating Current adapter (AC Adapter) comes with this Hard Disk Drive. Its input is 100 - 240 volts 50 - 60 Hz (so it can be used in countries that have 220 volts outlets). The output is 120 Volts 3 Amperes. I think it is better to disconnect it from the AC adapter when it is not in use. I guess the the USB power is not enough for such a big diskSince I am one of those guys that was alive in the 80s I am ultra amazed that they can make such incredible inexpensive drives with such a huge capacity. We are getting fast into the robot age thanks to marvels like these. We all will have enormously more cheap goods, it will be dirt cheap to produce a lost of goods. Almost anyone will be able to start a business with robots, because people will be able to do business without going trough the sadistic hellish nightmare that it is to hire people. We will have enrepreneurs everywhere and wealth that is several times the actual wealth because there will new businesses everywhere and much higher wages because robots will make output grow several fold and there will be much more money to pay hired people.For me this is not just a hard disk a drive: It is marvels like these that will ultimately give us freedom from the hellish nightmare that governments have created and that will give us so much goods that such future wealth today is hard to believe. Just my humble opinion,I backup a lot of photographs: It can take hours to copy 1TB but so far thisHard Disk Drive (HDD) does it with no problems.As far as I understand these high capacity drives have read /write heads that are extremely small, that are very close to the plate.This website [...] said about high capacity HDDs:"Imagine a fighter jet traveling in excess of Mach 5 (nearly 4,000MPH) at less than 1-inch off the ground, and being able to stop on any given blade of grass."In these HDD bits are so small, heads are so precise that I think repairing them may be quite difficult. So I prefer to ALWAYS back anything at least twice since I am very afraid of failures... And these HDD are so dirt cheap that it is better to buy several of them.

This is exactly what I needed to use Time Machine on my iMac. It was incredibly easy to set up and has been functioning as my back-up drive for a month now. I had no problem pairing it with Time Machine on the Mac and my files are there and protected. The drive appears to be pretty fast -- I have it hooked up to a USB 3.0 port -- and it backs up quickly. I've copied some larger files off it to my desktop and it's definitely faster than the 2.0 drive I used to have. I don't have specific speed specs, but it's good enough for me.I've had this drive for about six months now and it still works great. I use it mainly with my Macbook and it shows up on the desktop within a few seconds of plugging it in. I've unplugged it a few times without ejecting it (by accident of course) and it still functions great without any corrupted files. I use it mostly for my photography so I transfer a lot of large files and have been consistently pleased with how fast the transfers are. I also love that this drive doesn't get hot when plugged in all the time and that the cord is nice and short. Sometimes you want longer cables, but this one is the perfect size to connect to my Macbook and have it just sit behind it without a long cord taking up space.Lastly, I have had good luck transferring files between Macs and PCs with this drive. I initially used it on a PC and then ended up reformatting it after transferring all those files to my Mac. I only reformatted it to increase the security in the Mac OS.I've always had good luck with Toshiba drives. Of course, living in Colorado with the dry climate, I'm getting used to hard drives failing so I'll update this review if anything happens. I've had the hard drive in my iMac fail twice in the past year so in addition to this back-up drive, I also have online back-up. I'm a bit obsessed with not losing my files.
