  • newegg Single-chip USB 3.0 Design with 8-Channel Technology The Patriot Supersonic Magnum series eliminates performance bottlenecks introduced when using a separate USB 3.0 bridge chip by integrating a native USB 3.0 flash memory controller. This results in a smaller footprint and higher performance than bridge-based solutions. By pairing the controller with Patriot 8-Channel technology, the Patriot Supersonic Magnum achieves sequential read speed up to 200MB/s and sequential write speed up to 120MB/s.
  • newegg Ultra Durable and Portable A durable aluminum enclosure enables shock resistance up to 15Gs for better protection of your data. And a smaller physical size of the Supersonic Magnum USB 3.0 flash drive allows for even greater portability and style.
  • newegg A rating of 9/10 from The “lightning fast” and “light wight” Supersonic drive has won a rating of 9/10! “Sharing files, traveling from place to place, from work to home and back, it can’t get much easier and faster than with the Patriot Supersonic USB 3.0 Flash Drive.” “For another comparison test I ran a test on a Hitachi SATA 3GB drive and it too was beaten down by the Patriot Supersonic flash drive, but it did not come in last as it whipped the tar out of the "so-called" USB 3.0 drive from Western Digital. The Patriot Supersonic Flash Drive was 68% faster on the Read and 12% faster on the Write.” Read the full article by following the link:

5 out of 5 eggsGreat Drive

Pros: Fast USB 3.0 speeds under both Mac and Windows. Benchmarks for me at 151MB/sec write and 250MB/sec read. Housing seems solid.

Cons: Gets somewhat hot during large file transfers and the housing is a bit wide (which can block adjacent ports on some machines).

5 out of 5 eggsOwned for years

Pros: I've been beating this for years. It works and works perfect. I use it to transfer 50 - 100 mb size graphic files in mass all the time. I normally just copy or write the files and remove the drive. The computer you use sets the speed. Some computers that claim USB are better than others. Laptops are the worse IMHO. My highend Laptop gives good speeds but still not on par with my desktop. If your MB supports USB3 acceleration with a SSD to USB flash drive speeds with large files exceed manufactures speed rating. Small files are not bad but much slower.

Love it, I own 1-64gb & 2-128gb models.

Cons: None

Other Thoughts: Consider them pro use equipment. Worth every penny in time savings if you are on the clock.

5 out of 5 eggsGreat Drive so far

Pros: It's thinner than I thought it would be, which I like. Copied 6.28 GB of music in 6 min.. I like the colors of the drive. Opens files fast and I like the drive. I am completely happy with the drive I received.

Cons: None so far.

Other Thoughts: The drive measures 3 1/8" long, 1 1/16" wide, 5/16" thick. Mostly black which is the metal part and a light blue plastic.

4 out of 5 eggsGood performance, but mislabeled

Pros: Good, fast USB 3.0 transfers on both Mac OS and Windows 7.

Cons: The metal case was labeled 128 GB even though it's a 64 GB model (both based on what I purchased and the capacity in Disk Utility). It's also a bit wider than I like, and blocks an adjacent USB port on my MacBook Air.

2 out of 5 eggsHow not to do a high storage USB 3.0 flash drive

Pros: Fast speeds
Looks nice

Cons: Bad housing
Big clunky design
Not as fast as it says
Heat problems
Frequently reinstalls drivers

Other Thoughts: I bought this when it first came out as it was the first of its kind and seemed like the best on the market. After trying it out the first time I noticed that the 100+ read/write speeds was clearly a lie, I barely got over 60mbps write using fastcopy on a usb 3.0 port, 8 core processor, 32gb ram computer. A few weeks later the flash drive fell out of the housing when I tried to insert it into a laptop at work. I had to tape it together until I found some super glue.

The housing has a big, clunky, poor design which falls apart because when you insert it, you're actually pushing it apart from the adhesive that holds it together. It's also so big so if you have adjacent ports, you're going to have to remove one so make room for this big thing.

I transferred about 750gb worth of files from my old laptop using this and it got really hot. Hopefully the heat doesn't destroy the drive, but I'm sure it also played a part into the housing falling apart as enough heat can mess with the adhesive.

5 out of 5 eggsAwesome

Pros: This flash drive is amazingly fast. If you want something fast and don't mind paying the price, you need to get this flash drive. So far it hasn't failed yet. Bought it for $80 64GB on sale.

Cons: None for now.

2 out of 5 eggsAs Fast as Advertised, but as Unreliable as Unadvertised

Pros: Very fast write speed - our tests on a PCIe USB 3.0 card with SATA 3.0 spinner drives show around 85-100 MB/s write time. Read times are as fast if not faster.

Cons: * Unreliable - out of 40 we have purchased, 6 out of 20 failed right out of the box and 3 out of 20 failed in the field. The 6 that failed out of the box show up as "Removable Drive" in My Computer and are essentially read only devices. I haven't been able to get information about the field failures yet, but that's inconsequential to me because the failure rate is totally unacceptable.
* Too Wide - you cannot use a USB device in a nearby port due to the width of this device.

Other Thoughts: Note that the ones I purchased were not through NewEgg, but through a different supplier. I am exchanging the last batch of 20 that we purchased where 6 failed immediately. I can't be confident they will not fail while in use in the field.

4 out of 5 eggsFAST, but protective cap is poorly designed

Pros: The drive is FAST! BLAZING FAST! When connected to a computer that's optimized for USB 3, like a modern Mac, I'm able to transfer HUGE multi-gigabyte files in seconds, or at most a minute or two.

Cons: The protective cap doesn't fit securely at all, and is way too easily popped off, like when sitting in a backpack. It takes very little force to accidentally remove the cap. As a result, the connector for the drive can be easily damaged. If it wasn't for the poor construction and design of the cap, I would easily give this drive a 5/5 rating.

The drive is also very wide, so if you have USB ports that are close together and oriented horizontally, the drive won't fit with other plugged in devices.

Other Thoughts: If you can make sure that you don't damage the drive connector (since the poorly designed and constructed protective cap isn't at all reliable), then this drive is fantastic, due to it's sheer SPEED.

5 out of 5 eggsThe Best I've EVER used

Pros: I got this when it 1st came out. The speed was good then but better now. USB3 on the newer chipset are getting even better and my latest build with large transferred to SSD drives beat the write/read speeds. On a two year old laptop with a USB3 port to a standard HD it does about 1/2 of rated speeds but still kills USB2 drives.

Cons: None and I beat on this thing daily and the paint about 1/2 gone.

Other Thoughts: Some of the people complaining about corrupt files may be they are not using the eject function and leaving files open.

I use this to transfer large NEF files off the laptop to a faster desktop.

4 out of 5 eggsSpeeds so fast your face will literally melt.

Pros: Super fast, relatively affordable, looks awesome, and it has an aluminum shell.

Cons: Slightly higher price than other flash drives, but you get what you pay for. Also, I wish they made this device narrower, not so much of an issue with stacked USB ports but if it's side by side like my laptop it can run into

Other Thoughts: If you're tired of waiting for your files to transfer, this is the ticket to one of the best USB drives. I may have to purchase another one of these bad boys in a larger size.
