HyperX Savage EXO SSD: A small drive that's great for small jobs

When you write small amounts of data to this USB 3.1 Gen 2 SSD, it's as fast as they come. With large amounts of data—not so much.

HyperX Savage EXO is a name that evokes hardcore performance madness. But while this superportable and good-looking USB 3.1 Gen 2 (10Gbs) SSD is fast for everyday chores, it’s not the drive you want for offloading large amounts of data.

Design and features

The Savage EXO is a handsome, angular, silver and gray unit measuring approximately 5 x 1.9 x 0.4 inches 2 ounces. I like the way it feels in the hand better than the Samsung T5 and WD My Passport SSD, but the Sandisk Extreme Portable SSD still reigns supreme in that regard.

HyperX didn’t provide info on the controller, but the NAND is 3D TLC (we’re assuming 64-layer), and the whole deal is warrantied for three years. The only thing breaking up the smooth exterior is a USB Type-C port, for which HyperX includes both Type C to Type C, and Type C to Type A cables (The latter for older USB 2.x/3.x systems.)

The only thing to tell you that this is an external SSD is the Type-C USB port on one end of the Savage EXO.

There are two capacities available: 480GB (our test unit, available on Amazon), and 960GB (also available on Amazon).  The Samsung T5 or Sandisk Extreme Portable SSD were significantly cheaper than the Savage EXO at the time of this writing, and both those drives are far faster when writing large amounts of data. Be careful of the pricing on the HyperX website, which tends to remain high.


The Savage EXO suffers the same Yin-and-Yang performance characteristics as its Fury RGB cousin. It’s fast with the synthetic benchmarks and in light usage, then slumps when it comes to sustained writing. Anecdotally, it was fine running a live version of Linux (or Windows—not tested), which is something larger USB 3.1 SSDs are good for.

CrystalDiskMark 6 shows that the Savage EXO (gold bars) is a fast drive if you don’t write a lot of data in a sustained fashion. I.e,. large multi-gigabyte files. Longer bars are better.

AS SSD 2.0 had largely the same nice things to say about the Savage EXO when working with lots of small blocks of data (4K or 4,000 bytes).

AS SSD 2.0 agrees with CrystalDiskMark that the Savage EXO (gold bars) is a very fast drive while working with smaller amounts of data. Longer bars are better.

The large 48GB file writes were where the story changed. Indeed, snooping out slowdowns with TLC and QLC NAND when the cache runs out is why we write so much data to the drives in the first place.

Where the Savage EXO (gold bars) isn’t so savage is when writing large amounts of data. Shorter bars are better.

Long write times such as these aren’t unknown. Certain TLC drives we’ve tested over the years have done even worse, bottoming out at less than 100MBps. But controllers have improved, and some vendors have come up with dynamic caching schemes that offer much better performance for larger data sets. Apparently, this does not include HyperX yet.

Good, but not the best

Some users just use portable SSDs as a fast way to copy off a few megabytes of data and drop it in their pocket. For that, the Savage EXO is fine, as are most thumb drives. As I noted, it’s also good as a pocket OS drive.

But most users buy a large-capacity external SSD because they want a lot of storage for their large files. Writing said large files is where the Savage EXO goes from fast to not-so-fast. Unless you get significantly better deal on the Savage EXO, stick with the Samsung T5 (fastest) or Sandisk’s Extreme Portable SSD (best design).

Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.

This smart laptop was enjoyable to use and great to work on – creating content was super simple.

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries


As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

Taylor Carr


The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
