A flash drive

Amazon

The cloud is getting more reliable, but using it to move large files around still requires a very fast internet connection, so it still pays to keep a flash drive handy. This drive from SanDisk should be perfect for most day-to-day tasks.

It's got 64GB of storage — enough to hold thousands of pictures, songs, and documents, or hours of HD footage. It's also capable of transferring data at USB 3.0 speeds, so getting stuff onto and off of the drive will be snappier than using older flash drives.

An external hard drive

Amazon

Flash drives are great for smaller files, but it pays to have a local backup. Should anything happen to your computer's internal hard drive, it's nice to know that your data is safe.

At 1 TB, this should be more than enough to back up the average person's photos, documents, music, and movies.

A lock port

Amazon

If you've got tech you want to stay put, then protect it! Kensington lock ports are still available on a wide variety of laptops and are definitely a theft-deterrent.

Most Kensington locks are unlocked using a combo, but this one uses a key; so instead of having to remember a set of numbers, you'll have to remember to bring your key.

A USB hub with micro and regular SD card readers

Amazon

A hub with a twist! USB hubs have become a fairly standard accessory, but Cateck ups the ante a little by including a micro and regular SD card reader alongside the three USB 3.0 ports.

What makes the inclusion of the card readers so nice is that this hub puts them at arm's reach. Even though most laptops and desktops have built-in card readers, they're typically somewhat inconvenient. This is especially true if you've got a laptop in a stand hooked up to a display. This hub eliminates that problem.
