SanDisk Extreme CZ80
Reasons to buy
Reasons to avoid
Everyone wants their file transfers to go faster, but who wants to pay for it? You don’t have to spend much money to get a significant boost in power, though, and the 32GB SanDisk Extreme CZ80 is proof of that. Out of all the drives I tested, it represents the most bang for your buck.
The most impressive thing about this drive is that its speeds aren’t anywhere near the budget category, despite the price. In the large file test, it averaged a read speed of 229 MB/s and a write speed of 178 MB/s. Though that test didn’t reach its advertised speeds (245 MB/s read; 190 MB/s write), it came very close and actually surpassed those numbers in the CrystalDiskMark (CDM) test. Its small file testing proved somewhat worse for read speed, 123 MB/s, but still ahead of any competitors (by pricing) for write speed, 56 MB/s. These numbers actually come close to the drives I was testing in the high-end category—including the “pro” version of the CZ80, the SanDisk Extreme Pro CZ88—but at a significantly cheaper price.
The CZ80 is also one of the nicer looking and easier to use drives I tested. It’s slim and smooth design has a slider to push out the USB plug. The slider has a bit of a spring action to it, meaning you only have to push it part of the way and the drive does the rest of the work for you. It has a catching mechanism when the plug end is pushed out but not when it’s pulled in, making it easy to quickly “uncap” while also preventing you from pushing the end back in while you trying to plug it into your computer. The keychain loop is also quite large, making it much easier to thread than most of its competitors.
There are definitely faster drives and there are definitely cheaper options, but the CZ80 strikes a great balance between the two. It actually feels under-priced for the speeds it can reach. It’s such a fast drive that I can confidently recommend that this is the one you should get, even if you have extra money to burn. Going higher than this will get you more speed, but at an extra price that probably isn’t worth the money.

Patriot Supersonic Rage 2
Reasons to buy
Reasons to avoid
We’ve covered the drive that strikes a balance between price and power, but what if you just want the fastest USB drive you can get your hands on? That’s exactly what the 128GB Patriot Supersonic Rage 2 brings to the table. It’s got more storage than my personal rig’s SSD—and it costs more—but it has a lot of speed and space in a tiny package. In fact, it’s probably the tiniest way to store this much data available.
With the second-highest advertised read and write speeds of all the drives we tested, I had high hopes but realistic expectations. The Rage 2 is listed as having a read speed of 400 MB/s and a write speed of 300 MB/s, and while it predictably didn’t reach those high numbers it actually came surprisingly close. The large file test averaged 354 MB/s read and 187 MB/s write, while the small file test clocked in at 180 MB/s read and a much lower 34 MB/s write.
That write speed may seem damning, especially when put next to the 300 MB/s it claimed to get, but it’s important to keep in mind that pretty much every drive I tested performed drastically worse in the small file test than any other benchmark. Only a few of the drives made it above 40 MB/s write for that test, while only one managed beat the Rage 2’s small file read speed.
The Rage 2’s form factor is one of my favorite things about it, and one of the primary reasons I chose it over its closest competitor, the Corsair Flash Voyager GS. Even though it holds 128GB (there are also 256GB and 512GB versions) it’s one of the smallest drives I got my hands on. It’s slim, flat, and its sliding cap means it takes up even less space when you plug it in.
It was difficult to understand why some of the other drives were so bulky while the Rage 2 was designed to be so sleek and small. There is value in making a drive difficult to lose track of, but the Rage 2’s bright colors and easy-to-use keychain loop meant that wasn’t a concern. Additionally, it left all the other drives in the dust in terms of read speed. This is why the Rage 2 really shined; while other drives could beat it in certain tests, no other drive was so consistently at the top of every test. Put that in an attractive case and you have the best high-end USB drive money can buy.
Your average gamer isn’t going to need the amount of storage the Patriot Supersonic Rage 2 provides, but everyone can benefit from the speed. If you transfer files on a daily basis and want to gain back hours you’ve wasted waiting on slow transfers, this drive is your answer.
ADATA Superior Series 102
Reasons to buy
Reasons to avoid
If you're looking for a good, cheaper option, the 16GB ADATA Superior Series S102 is a worthy contender. It's wrapped in a durable body, doesn’t cost much more than lunch, and it blows crappy USB 2.0 drives out of the water.
The S102 is advertised with 100 MB/s read and 50 MB/s write speeds, and ended up testing pretty close to those numbers. It actually reached 116 MB/s read in the large file test, but it never quite hit its listed write speed, only averaging 36 MB/s. Still, its speed consistency was a good sign. The small file test saw a read speed of 84 MB/s and a write speed of 21 MB/s but, as I’ve said before, most of the drives I tested performed much worse with small files than large ones. Overall, it had decent and consistent speeds at a price much lower than you’d expect.
The S102 has a metal body and a removable plastic cap instead of a slider. I’m usually not a fan of caps, but this one has a catching mechanism that keeps it very securely in place. It can also be snapped onto the back of the drive when it’s plugged in and works well enough that it won’t just fall off with a slight bump. My fear with removable caps is that I’ll inevitably lose them, but this one feels hard to lose.
The S102 is definitely not the fastest drive I tested, but you get a surprising amount of power for a very low price. And if you are willing to spend a few dollars/pounds, you can double the storage capacity to 32GB.
The ADATA Superior Series S102 is a cheaper way to go, especially over an outdated USB 2.0 drive. The S102 will give you a noticeable and significant boost in speed for a very small price. It also has one of the nicest forms of any of the drives I used, regardless of price or speed.
SanDisk Ultra Fit CZ43
Reasons to buy
Reasons to avoid
Now that we’ve covered your best speed options at different price points, it’s time for something a bit different. Low-profile USB drives are ones that barely extended past the edge of the port you plug them into, and the best one you can get is the 32GB SanDisk Ultra Fit CZ43. A low-profile drive needs to be as small as it can possibly be while still staying functional, both in speed and convenience. It shouldn’t take up room, but you should still be able to fit it on your keychain or get it back out of the plug after you’ve put it in.
The CZ43 wasn’t the fastest drive I tested but it was definitely faster than any USB 2.0 drives and provides a worthy upgrade. In the large file test it had a read speed of 129 MB/s and a write speed of 31 MB/s, while in the small test it averaged 87 MB/s and 22 MB/s. These speeds aren’t amazing, but you shouldn’t be looking at the CZ43 if you’re only concerned with a drive’s speed.
The shape and form factor is what really counts when looking at low-profile drives, and the CZ43 shines here more than anywhere else. The drive hardly juts out of the USB port at all, and its end is rounded black plastic which allows it to pretty much disappear against your computer while plugged in. The end also has a red LED hidden under the plastic that acts as an indicator light when it’s getting power. The light is very helpful in making sure the drive is in all the way, and is otherwise completely unnoticeable.
Admittedly, the keychain loop is a little bit difficult to thread and the CZ43 comes with a cap that has nowhere to go while the drive is in use. I usually don’t like free-floating caps on USB drives, but since this one isn’t much more than the plug end itself, the extra protection while it’s in your pocket is appreciated.
Once again, it wasn’t the fastest drive I tested, but it was definitely the smallest. Realistically, the speed difference compared to other low-profile drives is negligible, and the CZ43 is slightly cheaper anyway. The smoothed black end also made it more aesthetically appealing while plugged in and easier to remove. For the record, no low-profile drive is easy to unplug once it’s in there, but this one was the easiest.
A low-profile drive definitely isn’t for everyone, but if you are specifically looking for one then the SanDisk Ultra Fit CZ43 is the way to go. If you are looking for extreme speeds while still staying relatively small then the high-end Patriot Supersonic Rage 2 will still satisfy but at a much higher cost.
