Our internet speeds are faster than ever. There’s plenty of online storage available for free or cheap prices. But the humble USB drive is still essential in 2016 Are USB Flash Drives Still Worth It In 2015? Are USB Flash Drives Still Worth It In 2015? USB flash drives are great for storage, but they have so many other uses. Here's how they're worth their weight in gold. Read More .

As fast as the internet is, it can’t beat the speeds you get from flash drives. Plus, when you have to transfer several gigabytes of data, why would you want to bottleneck your bandwidth?

A New Breed of USB Drives

Technology has a habit of shrinking in size as the years go by. And that has happened to an incredible degree with solid state drives (SSDs) 101 Guide To Solid State Drives 101 Guide To Solid State Drives Solid State Drives (SSDs) have really taken the mid-range to high end computing world by storm. But what are they? Read More . You can now actually get these in the same size as USB flash drives.


A solid state drive is different from the memory that most thumb drives use. While they are both basically flash memory, the quality of materials and the construction is much different. Typically, an SSD is of a much higher quality. Without getting into the technical details, here are some notable differences:

Choosing Between SSD and Regular USB Drives

It’s not a simple choice between the two. From the same manufacturer, an SSD-based thumb drive is faster and better than a regular flash thumb drive. But some flash thumb drives will be as good as low-quality SSD thumb drives too. Also, SSD USB drives cost significantly more than regular flash drives.

usb-flash-drive-generic2As a thumb rule, here’s what to take away:

  • Buy an SSD-based USB drive if you will use the drive regularly, need quick speeds to transfer data, and use it a little roughly. Important note: All decent SSD drives use USB 3.0 or 3.1 ports, and the high speeds work only on those ports.
  • Buy a simple flash USB 3.0 drive if you are on a budget and need to read data from the drive more than write data to the drive. It’s not slow, mind you. It’s just slower than SSDs. Chances are, you’ll still be fine with the speeds.

With that in mind, it’s time to pick. The choice is yours, based on budget.

1. Fastest USB Drive Around $20: 32GB Lexar JumpDrive P20

Lexar JumpDrive P20 32GB USB 3.0 Flash Drive - LJDP20-32GCRBNA Lexar JumpDrive P20 32GB USB 3.0 Flash Drive - LJDP20-32GCRBNA Buy Now At Amazon

The Lexar JumpDrive P20 has only 32GB of storage, but what it lacks in space, it makes up for with speed. UserBenchmark, which records real-world USB read/write speeds from regular users, ranks it as one of the best drives in this budget.


Its average read speed is 141 MB/s and its average write speed is 53 MB/s, which is nothing to write home about. But in this budget, it’s a Ferrari.

If you want more storage instead, don’t bother looking up the read/write speeds. Buy the 64GB drive that is closest to the $20 budget from Sandisk, Kingston, or Corsair. It will give you the average speeds that this price category is capable of.

2. Fastest USB Drive Around $40: 64GB Sandisk Extreme

SanDisk Extreme CZ80 64GB USB 3.0 Flash Drive - SDCZ80-064G-GAM46 SanDisk Extreme CZ80 64GB USB 3.0 Flash Drive - SDCZ80-064G-GAM46 Buy Now At Amazon

For 64GB drives, it’s a better idea to spend a little more than $20 and get the Sandisk Extreme CZ80. It garnered rave reviews from almost everyone who tested it, and WireCutter thinks it’s the best.


It’s not the fastest, though. The quickest drive still remains the 64GB Lexar Jumpdrive P20. But at $12 more than the Sandisk, and with a fiddly sliding mechanism, it’s not worth it. While the Lexar has a higher read speed, its write speed is slower than Sandisk.

In the end, Sandisk’s 246 MB/s read speed and 196 MB/s write speed is a better deal than anything else in this price. And it’s second fastest overall.

Since the publication of this article, Sandisk has released a new version of their USB drive, the Sandisk Extreme Go.

3. Fastest USB Drive Around $60: 128GB Patriot Supersonic Mega

The Supersonic Mega replaces the older Magnum 2-line of USB Flash drive. It performs similarly to the Magnum 2, except better in all performance categories.

While the Patriot Supersonic Mega is technically an SSD-based thumb drive, it doesn’t exactly perform like one. That said, it’s faster than the average 128GB flash drive for this price.

fastest usb drive

Overall, the Supersonic Mega is a fast drive for the money, though I don’t see many analyses of it around. It looks like a uniformly better and cheaper replacement for the Magnum 2 (which itself was an amazing drive).

4. Fastest USB Drive Around $100: 256GB Patriot Supersonic Mega

Patriot 256GB Supersonic Mega USB 3.1/USB 3.0 Flash Drive With Up To Read 380MB/sec & Write 70MB/sec- PEF256GSMGUSB Patriot 256GB Supersonic Mega USB 3.1/USB 3.0 Flash Drive With Up To Read 380MB/sec & Write 70MB/sec- PEF256GSMGUSB Buy Now At Amazon

The folks at TweakTown reviewed the drive and thought it was pretty good. RelaxedTech also thought highly of the drive. It comfortably outperforms the Magnum 2’s read speeds with an average of 334 MB/s. And its write speeds are a respectable 76 MB/s.


Forbes tested the older, but similar-performing, 512GB Magnum with two batteries of tests, both real-world and synthetic. CrystalDiskMark, one of the best flash drive speed testers 5 Apps to Check the Speed of Your USB Flash Drive in Windows 5 Apps to Check the Speed of Your USB Flash Drive in Windows USB flash drives are not all made equal. Even flash drives of the same type can differ significantly in read and write speeds. Use these tools to benchmark your USB flash drives. Read More , recorded a read speed of 380 MB/s and a write speed of 327 MB/s. That’s far higher than anything else you’ll get in this price range.

There’s also the Patriot Supersonic Rage 2, which isn’t as fast the Magnum. On the outside, it has a rubber housing that protects it from drops and spills. Not a bad deal, if the durability ranks higher for you than speed.

5. Fastest USB Drive Above $120: 512GB Patriot Supersonic Mega

Patriot 512GB Supersonic Mega USB 3.1/USB 3.0 Flash Drive With Up To Read 380MB/sec & Write 70MB/sec- PEF512GSMGUSB Patriot 512GB Supersonic Mega USB 3.1/USB 3.0 Flash Drive With Up To Read 380MB/sec & Write 70MB/sec- PEF512GSMGUSB Buy Now At Amazon $149.99

The 256GB version is the best value for money but if you need a larger capacity, the Mega also comes in 512GB. Even so, I’d advise picking the smaller driver. Apparently, the Magnum’s performance doesn’t drop for lower capacities. More or less, if you’re willing to spend big bucks, this is the USB key to buy.

The aluminum housing gives it additional durability, while the new USB 3.1 compatibility makes it a little more future-proof. To make the best use of it, you should probably get a PCI-express USB 3.1 card as well.

The bottom line is that if you want the fastest USB drive with the most amount of storage space, the Patriot Supersonic Mega is it.

Flash Drives vs. Portable SSDs

The shrinking of SSDs has resulted in one other phenomenon. Portable hard drives with SSDs have also shrunk in size. While bringing it down to the same size as a thumb drive is harder for the manufacturer, a slimmer and sleeker portable drive isn’t as hard. Take, for example, the Samsung T5 or Angelbird SSD2Go Pocket, which seem like excellent ways to get extra storage.

Plus, you can also get wireless portable hard drives for more efficiency. It’s reached a point where you really have to wonder. So reader, which of the two makes more sense to you, a flash drive or a portable SSD?

    Corsair has faster write speeds around 140-180 MB/s. My Survivor Stealth 256GB averages 150 MB/s write (and since write is the important measure..)

    You've got it right... an SSD based flash drive is MUCH faster than a normal flash drive... so why do you go out and test normal flash drives?

    The Corsair 256 GTX is an SSD based flash drive that gives blazingly fast reads and writes.

    I've got the Patriot 512GB flash drive and it's a slug by comparison.

    The Corsair is not all that expensive either given it's size.

    Just don't buy a Corsair GT 256 GB... which is a normal flash drive... and fairly slow (accidentally bought one).

    Just wish they would make a 512GB version of the Corsair GTX.

    Some people in the comments make false claims based on their own experience about the speed of these drives, most of them being dissapointed. What they fail to understand is that in most situations their hardware cant keep up with the speed of these drives (reading from busy HDD, fragmented, etc), they plug it on USB 2.0, they have their files fragmented or make copies of thousands of small files, and the list goes on. Don't blame the usb drive lol.

    I saw your site and ordered Sandisk Extreme 64GB. It doesn't even reach upto 50 MB/s writing speed. It ranges a maximum of 48 MB/s only. Falsely advertised from Sandisk. Huge disappointment :(

      You have probably put it in a usb 2.0 port. Try putting it in a usb 3.0 to get the proper speed out of it. If not then maybe your testing is off. It's definitely not false advertising, it will be your human error.
      I have one and it runs around 200mbs read

        If you read what ARUN A B has written...He is talking about WRITE speeds. You are quoting READ speeds. Read speeds are always faster. Check again, Anonymous and check your WRITE speeds. My results, though on the smaller drive give me a max of mid 90MB/s, in extreme cases, with an average of around 50MB/s.
        This article states write speeds of OVER 200MB/s. SanDisk site quotes write speeds of UP TO 190MB/s...Which equates to average of around 140-150MB/s. Then there also CAN be other issues with this drive. Notice emphasis on the word "CAN".
        This article contradicts the SanDisk site.
        The best drive here, IMHO, is the Lacie XtremeKey, though it does not show the 64GB, which I am working with and talking about now. It is tough, reliable, waterproof (when cover is screwed on) and as I stated earlier, gives an average write speed of 137-139MB/s. Fastest write speed has been 155MB/s. Though in stating this, one should always to remember to take care of the software eg: proper ejection etc.

      I have the same Sandisk Extrerme but in the 32GB. The fastest write speed I achieve with it is in the mid 90MB/s. And NO! We are NOT idiots as was inferred to you by Anonymous. I only use my USB3.0 ports and also use ASRock XfastUSB. Maybe it is the size but there is NO WAY IN THE WORLD it will get 200MB/s write speed. Read speed is around 200MB/s but the write speed is what I am after.
      I also have the XtremeKey 64GB. This drive is my fastest with constant write speeds of 137-139MB/s.

        Dear David, 32GB version is 2x slower in respect to write performance than 64GB one. They use more "stripes" in 64GB model, aka when writing a block of data, it is split into more chunks which are written in parallel. Write performance is also strongly dependent on operating system and file system you use. In Windows, NTFS filesystem is the usual choice and this is not the best performing filesystem available. Also, Windows uses synchronous mode on external media by default. Synchronous mode updates filesystem journal more frequently, so when writing data to the USB key, metadata is updated very frequently, so in fact apart from what user expects, system writes more data (data about data) behind the scenes, which causes slowdown. Try to format the key using FAT32 or exFAT and check again. Also, when they claim up to 200MB/s, they claim it based on measurements using the best performing filesystem and continuos write of a big file (the best case). In real life, one copies mixture of big files and plenty of small ones, so actual average perfromance will be a bit slower. Journalling and synchornous writes slow the operation down. I observed that the same flash key is much faster when writing under macintosh then in windows (holds true with Sandisk Extreme 32GB as well).

          I own the 64 GB version of it, and although it didn't reach the 200 MB/s write on my machine, I usually see around 180-190 MiB/s when copying something from my SSD onto it.

          You always have to consider the read speed of the drive you are copying stuff from.

          Ofcourse it will be limited by USB 2 to around 20-30 MiB/s.
          Ofcourse it will be limited by regular hard drives to their respective speeds (Think of around 100-130 MiB/s for a 3,5" 7200 RPM drive)
          Ofcourse the filesystem can impact the speed (ExFAT is faster than NTFS due to no journaling, FAT32 limits file size to 4 GiB which can be quite annoying especially with a big drive)

      So many silly comments.
      1) No he wasn't using it on USB2, it could not achieve 48MB/s on USB2.
      2) The USB controller is often a bottleneck on high end USB3 flash drives, particularly those with SSD controllers in them.
      3) No NTFS is not the usual Window filesystem for USB flash drives. They are typically exFAT in this capacity and larger.
      4) All your peak MB/s speeds are of little consequence unless that's how you're actually using the drive. 4K read and write speed will be far more important to most people, unless all you use it for is moving large amounts of data around and frankly, that's what networking is for.

        November 28, 2015 at 12:47 pm

        This is raw speed. The USB 2.0 protocol has its own overhead, so you will never see 60MB/s read or write performance. Actual data are encapsulated into packets, there are overhead bits as CRC etc. According to my experiences, real max. speed of USB 2.0 in high speed mode is around 40MB/s. Theoretical max. speed based on protocol specs. is around 52MB/s, but I've never seen it.

    Maybe the opening sentence should have read that the Sandisk is the fastest of the "affordable" or "every day" USB drives. The IronKey Workspace would be a great addition for protecting sensitive data, but I wouldn't spend that kind of money on a drive just to put photos on. I'm guessing the author was meaning to imply the same thing.

    Aside from the above, I use USB drives mostly for transporting large amounts of photos/files between myself and my children. However, I do keep one 16GB drive in one of the ports of my 7-port hub strictly for Windows (7) to use (SpeedBoost). I also have a couple of drives that I use to keep different versions of some files that I work on frequently. One thing I can say for certain, using these USB drives are a lot faster and easier than constantly having to burn files to a CD or DVD!
