Top 10 best external desktop and portable hard disk drives
1- Maxtor D3 Station
If you want to buy an external hard disk drive but don't want to break the bank, check out the D3 from Maxtor, which is now owned by Seagate.
Compatible with Mac and Windows devices, it is powered by a mains adaptor and offers a number of applications like AutoBackup, Secure Drive and SecretZone, all preloaded on the device.
2- Seagate 5TB Expansion
Like its sibling, the Seagate 5TB Expansion has 64MB of cache and demands an external power supply unit to get it going.
3- Seagate STEB4000200 4TB Expansion
It has a 4TB capacity, a 5900RPM rotational speed, 64MB of cache and, because it is a 3.5-inch model, will also need to be connected to the mains to work.
4- WD My Book 8TB
Note that the drive is cheaper than an equivalent 8TB internal hard drive which means that if you need a bunch of high capacity drives for your NAS, you might save yourself hundreds of pounds by buying those and taking the hard disk drive out.
5- Seagate Innov8 8TB
The Seagate 8TB Innov8 range is worth a mention. It is a normal-size 3.5-inch desktop hard disk drive but doesn't need an external power supply to run.
6- WD My Book Duo 16TB
This item can only be ordered on request but is worth the wait. It has two 3.5-inch 8TB WD Red HDD at its heart and although this is a NAS (network attached storage), it can still be used as a DAS.
7- Maxtor M3 4TB hard disk drive
Maxtor, a hard drive brand purchased by Seagate a few years ago, has quietly been revived and is our overall best buy when it comes to portable hard disk drive, models that can be powered using the USB port only.
8- WD My Passport 2TB
It can actually stream content to more than one device, acting like a small network attached storage. WD says that up to four HD videos can be streamed simultaneously thanks to the Wireless-N MIMO-enabled connectivity.
There's a SD card slot to backup all your content (albeit slowly) and its battery is big enough to power it for up to six hours (after that, you can always use a portable battery to charge it).
9- Seagate Wireless Plus 2TB
A special mention for this drive. If you're partial to Seagate for whatever reason, their Wireless Plus drive matches the WD drive above when it comes to capacity and connectivity.
It doesn't have a card reader and can connect only to three devices, but the Seagate Wireless Plus 2TB drive makes up for it by being much thinner and lighter. It also has a much longer battery life (up to 10 hours).
As for the WD model, there's a 5400RPM hard disk drive at its heart. It has a two-year warranty and you can use it as a Wi-Fi hub to share a single internet connection with up to seven devices.
10- iStorage diskAshur 2TB
iStorage hard disks are the choice of governments and multinational organisations around the world, with good reason – they're designed to make life very difficult for anybody who tries to access unauthorised data.
The PIN-protected drive can be set to self-destruct if tampered with, the data is encrypted (256-bit AES) and there are multiple forms of protection to ensure the bad guys don't get in no matter how persistent. When you consider all that extra security, the prices aren't too frightening, either.
Sure, it is expensive (costing around four times the price of an equivalent 2TB drive) and unlikely to be the fastest around but you do get something that's essentially uncrackable. Bear in mind, though, that you won't get any help if you happen to lose the password.
