This is a 4TB external 2.25 inch hard drive that runs totally off the USB port with no external power source required, making it very portable. I am using it to backup two laptops and two desktop computers for me any my wife and my two kids laptops. A total of six computers. After a complete backup for all six computers, the used space on the drive barely moves. This drive is a must have for anyone who needs a very large amount of space and a portable drive that can easily be moved from computer to computer and carried with you on the road. For the money, It is a fantastic unit.

Four of the black ones corrupted data on me last year and ruined a 8 months long backup project I was doing. I have to do it all again. I'm too old for this nonsense. It's a shame, because I love the drives otherwise. It was months before I found out I was writing to bad blocks. What a horror! I thought maybe my USB 3 ports were the problem, but I have a bunch of these in blue that have had zero problems. I don't think it's a coincidence. I think I caught a bad run of drives. Now I keep a close eye on condition of my drives with a utility called SMART Utility. SMART your drives, folks. Sadly I couldn't even test the Seagate warranty, because I took the drives out of the cases to tech them on a SATA buss. Ah, computer life... May you have better luck with your computer life!

The Backup Plus Slim series of HD are excellent (I have two 2TB and 1 4TB) and affordable. It is certainly not the fastest drive but good enough for my day-to-day archiving purpose as well as running it as a boot disk on USB (even USB 2.0 on a 2009 iMAC (whose internal HD died, and buried inside since I don't want to open the iMAC). Now I can simply take the drive on a trip and boot up any iMAC. The 4TB has the same footprint as the 2TB, only a bit thicker. Please note that there are many Seagate 4TB models, and not everyone is a slim one (the box DOES NOT say it is slim, but it is if you have the Model STDR40000100. I also have the 4TB Backup Hub and it is very bulky in comparison (its advantage is it has its own power and can connect other drives to it). I had the 2TBs for over a year and they perform well. I expect the same for the 4TB. They work for both Windows PC and Macs. However, I find it almost impossible to eject the drives under Windows 10---it is always "in use" (either because of Dashboard, or Windows Backup, or Norton Utility and I have to shutdown the machine to remove it. Very inconvenient. No such problems on a Mac (even if Time Machine is running using a partition on the drive).Read full review

I am impressed with the size of the drive. Very portable. Great news for Linux users. It works with no installation and sees the entire capacity of drive. These drives are formatted to NTFS from Seagate. If you are using a lean version of Linux like Xubuntu make sure you have gnome-disk-utility 3.18.3.1-1ubuntu1.1 installed. It will give you more options for disk management and allows better compatibility of the NTFS format to work in Linux. I am sure you will be thoroughly impressed with the functionality and portability of this external USB device.

This was purchased to serve as an external nightly backup drive for the server at my place of work. We previously had a 1.5 TB backup drive that just didn't have enough room anymore. So I bumped it up to this 4 TB drive. Windows Server 2012 Essentials found it, formatted it, and it has been backing up nightly with zero issue. It is stored in a Sentrysafe water/fire proof storage data chest so I can't answer how loud it is. Speed seems okay, took awhile to get the first backup done. So far it's reliable though only in operation for a few weeks.
