3 out of 5 eggsNot nearly as fast as advertised.

This review is from: CORSAIR Voyager GS 64GB USB 3.0 Flash Drive Model CMFVYGS3-64GB

Pros: Brushed aluminum is nice to look at.

Cons: Benchmark puts it at 200mb read and 40mb write. The back of the package indicates 260 read and 70 write.

Other Thoughts: The red Corsair GS drive performs much better at 200 read and 100 write.

4 out of 5 eggsSolid performer.

This review is from: CORSAIR Voyager GS 64GB USB 3.0 Flash Drive Model CMFVYGS3-64GB

Pros: - Quality construction.

- Aluminum scratch-resistant surfaces.

- Feels super fast compared to USB 2.0

- One of, if not, the fastest flash drive in it's range.

- Instantly detected when plugged in either USB 3.0 or 2.0 port.

- Read and write speed maximums are as advertised. (Benchmarked using HD TUne Pro and CrystalDiskMark)

Cons: - Easy to lose cap. It comes off too easily if knocked against something.

- Has keyring/neck-strap loop at the other end of the flash drive, but no keyring/neck-strap comes included.

- Bulky in size. (1 inch wide and just under 3 inches long)

- Will most likely block adjacent USB port(s) on devices that have them placed closely together.

- Price is on the high-end. The 128GB model is a better deal per gigabyte. (Price varies)

Other Thoughts: For measuring real world speeds, I did several transfers with different file sizes from a SATA III Hard Disk Drive:

From SATA III HDD to Voyager GS in USB 3.0 mode:

Between 43 mb/s to 60 mb/s (depending on file size and amount of sub-folders.)

From SATA III HDD to Voyager GS in USB 2.0 mode:

Between 27 mb/s to 30 mb/s.


Benchmark Results:

HD Tune Pro:

Read Speed: 280.8 mb/s

Write Speed: 170.2 mb/s

CrystalDiskMark:

Read Speed: 287.7 mb/s

Write Speed: 183.3 mb/s


I have no complaints about this flash drive's performance. It shows consistent speeds and works flawlessly for its intended purpose.

However, the external casing design could have been better. The cap feels like it's easy to lose and could have been attached more securely. It's no problem carrying the flash around when its stored away in a pocket or a bag somewhere, but if it's hanging from a strap or keyring, the cap will easily get knocked off even if lightly bumped against something hard. It may not be an issue for some nor is it really a big issue at all, but I think it's still worthy of having an egg taken off.

If your concern is primarily with quality and performance rather than price, then the Voyager GS is definitely a solid choice.

5 out of 5 eggsFAT32 to NTFS to FAT 32 to NTFS again

This review is from: CORSAIR Voyager GS 64GB USB 3.0 Flash Drive Model CMFVYGS3-64GB

Pros: One very important thing I forgot to mention is that the drive comes pre formatted as FAT32, lot of the copying and writing test I did were both, as I formatted the drive to NTFS in USB 2.0.

When I realized that the drive was FAT32 in USB 2.0 mode I formatted to NTFS for USB 2.0 but I revert to FAT32 for USB 3.0 testing and formatted to NTFS for a final USB 3.0 testing.

In Windows 7 and 8, by default you cannot format to FAT32 (but ex-Fat with the Voyager GS), so I googled and downloaded a free software program that allowed to revert back and forth between the two.

Either way, in both file systems the Voyager GS performed well. But NTFS is my file system of choice.

Cons: None

5 out of 5 eggsUltra-Fast, just don't pair it with a slow drive

This review is from: CORSAIR Voyager GS 64GB USB 3.0 Flash Drive Model CMFVYGS3-64GB

Pros: The speeds on the back of the package read: 260/70 MB/s Voyager GS USB 3.0 VS typical 85/70 MB/s. But in reality the writing speeds of the Voyager GS surpassed the 70MB/s, in many cases I was getting up to 137MB/s, a 560MB file would transfer in less than 7 seconds. CrystalDiskMark pretty much gave me the same results as the info on the back of the package, except I got 290MB/s for reading and 110MB/s writing.

There were times when I transfer to the Voyager GS close to 25GB of multiple files and the speeds would come down to as low as 24MB/s but gradually it would pick up, my guess is that some files were to small, whereas single large (500MB+) file would almost take not time.

It is a fast drive, for both reading and writing, but when transferring files from a slow (USB 2.0 flash drive or memory card like SD or micro-SD) to the Voyager GS, expect slow reading/writing speeds. In one case the Voyager GS was writing at 24MB/s from a file being copied to from a Micro-SD. Writing to the Micro-SD was fast but it takes a while for the Micro-SD to catch up, with a painful 11MB/s as top writing speed.

Overall, in all the test I performed with this Voyager GS were on par with the description from Corsair, it's ultra fast, copying to and writing to and vise versa, even when plug into a USB 2.0 port, but you'll get this message "This USB Mass Storage Device can transfer information faster if you connect it to a Super-Speed USB 3.0 port".

The one thing that I didn't like was that I tested this with 4-5-6 different benchmarks, 2 of them, the results were just as described in the package but the rest gave me bad and inaccurate results, which is why I don't start with benchmarks but copying and writing to the drive in as many ways as possible to get the most accurate in real world performance.

I wish this drive would come on a 32GB size, because this is the only Flash Drive to be fully compatible with XBOX 360 performance recommendations, I've used several other Flash Drives and while they work fine, I get a warning from the XBOX in regards of the performance after it's been formatted but I used them anyway.

I've owned and had several Flash Drives (also Wintec Filemate Elite 32GB 95/50MB/s SD card) and the Voyager GS is the fastest so far, if you want fast readings and writing speeds, this is the drive for you.

Cons: Here's comes what is just a little bit of a "Con", the flash drive is so wide that in all of my laptops when the drive was plug in one port, the port next to it I was not able to plug any other drive to it because it was partially blocking it. So, make sure you have a 3rd port. This is not going to be the case on a desktop.

Maybe, because of its aluminum construction, when I plug the flash drive right next to my Logitech's USB mouse receiver, the signal died, this happened when the Voyager GS was right in the middle of the receiver and the mouse, blocking the signal, but when I moved my mouse to the Voyager was not in between, the signal came back. This was the case in my desktop only, in the two laptops I tested no interference at all.

Other than those two, I don't see any other problem. The cap? Is not really a problem, it fits there tight and secure, I was shaking the flash drive vigorously to see if the cap would come out flying, but no, it never did. it's anodized aluminum, not air-brush.

Other Thoughts: My test benches were:
2 Acer laptops, both Core i3, one running Win7, 2nd one running Win8. USB 3.0 port in one but none in the 2nd one. Nevertheless in both cases the speeds were accurate and as described by Corsair.

Desktop, it does not have a native USB 3.0 chipset but instead a PCI-e x1 USB 3.0 card (Item#: N82E16815124122) and I find the speeds just the same as the one laptop with a native USB 3.0 chipset. But also when the Flash Drive was plugged in a USB 2.0 port, the speeds were the fastest, compared to my other USB 2.0 flash drives, and I do own about 6 other, ranging from 4GB to 32GB and a few SD and Micro-SD.

You are getting a high-performance drive, if not the fastest ever, and this makes it so much easier, I highly recommend this drive, but I would love if Corsair ever decides to release a 32GB version, because I will buy it for my XBOX, I have a 250GB it, but I own two different version of the XBOX, can't really swap hard drives.

4 out of 5 eggsA Difficult Item to Review

This review is from: CORSAIR Voyager GS 64GB USB 3.0 Flash Drive Model CMFVYGS3-64GB

Pros: 64GB,

USB 3.0 flash drive.

Feels sturdy and well built.

Write speeds up to 140MB/s and read speeds up to 260MB/s in my testing.

Performed very well as a USB media drive while hooked up to my router.

Does not have any bloatware installed.

Cons: Size, this is much larger than most flash drives on the market. It's physical size, to me, would be the largest deterrent from me purchasing one in the future.

The cap design feels cheap. For the sturdiness of the body, and the airbrushed aluminum, to have a cap that most assuredly will be lost is a let down.

Heat. Through my testing it was immediately obvious how warm the drive gets during extensive use. It is warm to the touch, something I personally have not experienced from other flash drives, albeit none any larger than 16GB.

Other Thoughts: The reason for me removing 1 EGG.

It is my personal opinion that this drive falls into a niche market between the smaller physical stature drives and the obviously larger external HDD"s. Because of this drives size it is unreasonable to attach it to a key chain, which means you will either be carrying it in your pocket, a laptop bag, or some other form of carrier. This makes it more susceptible to loss or theft than an external HDD and a smaller flash drive that you can put on your key chain.

My personal recommendation, if you do not have specific need for 64GB (or more) of storage on a flash drive I would stick to the smaller capacity flash drives. If you do need this amount of storage space and an external HDD you would have to carry around just isn't feasible, I would go with the 128GB model instead. At the time of this review, it is selling for $6 more.
