The 11 best high-performance storage devices

The VisionTek USB Pocket SSD looks like any other high-capacity flash drive with a USB 3.0 connector, but on the inside it is a full-blown Solid State Drive (SSD) featuring a high-performance SandForce controller.

Yes, this is a pocketable SSD.

This means you'll experience up to 455MB/s reads and up to 440MB/s writes, which is as quick as some of the fastest internal SSDs currently available.

Highly recommended!

This is an interesting idea. It's a portable storage drive that not only acts as a standalone USB storage drive, but it can also slot into Lexar'sProfessional Workflow Hub allowing it to be integrated with my media card readers.

If you're handling a lot of photos and video, then this approach gives you a flexible way to add dedicated storage to your system. This is especially useful if you are working on a system that either has limited storage space, or is using a hard drive as opposed to a faster SSD.

Price: 256GB for around $130/512GB for around $170.

For a few years now I've been a fan of Western Digital My Passport drives. They're small, fast, and reliable. Given my happy past experiences with these external drives, I was excited when Western Digital sent me a pair of 2TB My Passport Pro.

Unlike the My Passport drives which house a single drive, the My Passport Pro houses two drives. This makes them thicker, but the two drives have benefits. Using the supplied software you can configure these drives as RAID 0 or RAID 1 (depending on whether you want speed or data duplication) or you can set them to appear as separate drives.

The My Passport Pro comes equipped with Thunderbolt connectivity, and the cable is attached, which is great because it means I don't have to buy one, and won't lose the one supplied! This drive delivers transfer rates as high as 233 MB/s, so it's no slouch. The drive also gets power from the Thunderbolt connector so there's no separate AC adaptor to carry (or lose).

Price: Starts at $299 for 2TB.

Price: $899.95.

Store up to 64GB is something not much bigger than your fingernail.

Not only are these drives great when you want to pack the maximum amount of storage into the smallest space possible, but they are also work great as additional storage for tablets, smart TVs and car stereos where low-profile is paramount.

I have a few of these, and other than being easy to misplace/lose, there's not much wrong with them.

Price: 16GB for around $10/32GB for around $20/64GB for $35.

A portable drive that you can slip into your pocket, but it also features 256-bit hardware encryption and integrated local and cloud backup solutions that allows you to make use of your Dropbox account for create a separate backup.

This offers up to 2TB of storage is a small, robust and stylish package.

Price: 1TB for around $80/2TB for $120.

One of the biggest worries when carrying data about is loss. Sure, it sucks being down a storage device when you've left it on the train or had it stolen off you, but what sucks more is realizing that you didn't encrypt something important, and now that data is potentially out in the wild.

You might choose to mitigate this by using a software solution, but in my experience people forget to use this at the most inopportune times. Far better to use a hardware encryption solution that forces the user to encrypt the data at all times.

This is where the IronKey comes into play. Not only does it offer AES 256-bit hardware encryption, but it is also built to resist very determined and sophisticated attack. The device will permanently self-destruct after 10 consecutive incorrect password attempts, and a ruggedized, waterproof metal chassis resists physical break-ins and features a tamper evident design.

Price: The S250 starts at $110 for 2GB.

I remember a time when I dreamt of owning a 1TB hard drive. Now you can fit 1TB of storage into a pocket!

The Kingston DataTraveler HyperX Predator combines colossal capacities – up to 1TB – with incredible performance – read speeds of 240MB/s and write speeds of 160MB/s.

This is a monstrous drive that feels more like a metal ingot in your pocket than a flash drive. I'll be honest with you though, if you have to ask what the price is – over $1,000 for the 1TB version – then this drive isn't for you!

Price: Eye watering.
