16GB isn't a lot of space. You might need a way to add more.

While Chromebooks are mostly cloud-centric machines, there are still quite a few offline packaged apps available. Sometimes, when you have a lot of those installed alongside media like music, video and pictures, there's not much room left. Add in Google Drive syncing, and running out of space is a real possibility — especially on the 16GB storage models.

There are a few things you can do to help if you ever hit the storage wall. Let's have a look at some of them!

Adding an SD card or USB thumb drive is an easy option

This one is simple. Your Chromebook has an SD card reader on the side, and if you add a card to it, all the space on the card is available to the operating system for storage. The same goes for a USB thumb drive.

There are a couple issues to be aware of here. The first is that you might not want half of an SD card or a USB thumb drive hanging off the side of your Chromebook where it can get broken. There's an easy solution — use half-height drives or cards.

Your Chromebook can read and write to SD cards or USB drives formatted as FAT32, vFAT and exFAT. Your Chromebook can format or reformat an SD card, but it will only do it using the FAT32 file system. There is a 4GB file size and 8TB partition size limit using FAT32, so if you need to read and write files (like movies) bigger than 4GB it's best to format the card on another machine. You can do that on a demo computer at Best Buy if you need to.

Lastly, tinkerers might want to use an ext file system on their portable drives. Besides issues with file permissions you might run into, remember that journalizing may cause flash storage to wear out fast.

A less portable solution — A USB hard drive

Like portable flash storage, your Chromebook can use a USB hard drive for a lot more storage at the cost of portability. Most any USB hard drive will work, so look for the fastest one (USB 3) you can afford, even if your Chromebook doesn't have USB 3 ports — your next one will.

Your Chromebook can access files on a USB hard drive using these file systems:

  • FAT (FAT16, FAT32, exFAT)
  • HFS+ (read-only on journaled HFS+)
  • ISO9660 (read-only)
  • MTP
  • NTFS
  • UDF (read-only)

You'll not be able to easily format a USB drive in Chrome OS, so you'll need to do that on another computer. Also note that there is no defragmenter in Chrome OS, so if the drive gets "clogged" up you'll need to do that on another computer, too.

Protip: Your Chromebook can also read files (like media in any of these formats: 3gp, .avi, .mov, .mp4, .m4v, .m4a, .mp3, .mkv, .ogv, .ogm, .ogg, .oga, .webm, .wav ) from a USB CD-ROM or DVD-ROM drive, so it might be worth burning your videos and music to a disc if you have room to tote a USB drive around.

Use a second Google Drive account

And don't sync it offline with your Chromebook.

It's easy to switch users on Chrome OS, and downloading a file to a removable drive through the file manager means it can be available for all users. Every account gets 15GB of free Google Drive storage, and it will show in the file manager where you can easily access any of it.

Of course you can also choose to not sync your Google Drive files offline to save even more space from the Google Drive app settings.

You might be able to put a bigger drive in your Chromebook

Chromebook SSD replacement

This is a little more extreme than any of the other options, and most Chromebooks don't support it because the internal storage is soldered directly to the board.

Some notable models that can be upgraded with a bigger storage drive include the Acer C710, the Acer C720, the HP Chromebook 14, The Samsung Series 5 (and Series 5 550) and the Cr-48.

It's easy to do on some models like the Acers or the Samsungs, and very difficult to do on the HP 14 — but it can be done.

You also might need a specific drive like an M.2/NGFF SSD and it's best to stay away from drives bigger than 128GB. We swapped out the SSD on a trusty C720 if you want to see what you might be up against.

Have reasonable expectations

Chromebook apps

When you buy a $200 laptop that's built to be lean and speedy, you shouldn't expect a 500GB spinning disk drive under the hood. You wouldn't be happy with the performance even if you did. That's just not how Chromebooks are designed, and even the most expensive models only come with a 64GB SSD installed.

With tempered and well thought out expectations, and these few tips you should be able to manage all of your storage needs. I'm building a new desktop workstation for the office, and I have 6.5TB of storage sitting here to go in it. One day, I'll need to worry about it getting full, and I'll have to pay closer attention to what I save and where I save it. No computer is immune.

We have a feeling that Chromebooks with bigger storage sizes are coming, as it will soon be more expensive to spec out 16GB drives instead of 32GB. In the meantime, be sure to keep everything backed up somewhere, and learn to delete the things you'll never need again.
