3 out of 5 eggsGet the Voyager GO instead

This review is from: CORSAIR Voyager Slider 64GB USB 3.0 Flash Drive Model CMFSL3B-64GB

Pros: Lots of storage for a pretty attractive price.

Thick and somewhat built well, would easily take dropping and probably a wash cycle or two.

Capless, retractable design means you won't have to keep an eye on a cap to protect the USB interface.

Has a loop for a lanyard and a blue activity LED.

Good USB 2.0 performance.

Cons: Abysmal USB 3.0 performance.
Comparing this device to a Voyager GO 64GB flash drive, the GO outperforms it by nearly double at all tasks, and the GO is not that much more ($7 as of this writing). I tested in 2 ways, using a synthetic benchmark as well as several 'real world' tests using file transfers to the drive.

Using UsbFlashSpeed.com's free benchmark tool, the Voyager Slider had an average of 14.15 MB/s write and 61.99 MB/s read using a USB 3.0 port. Comparatively, the Voyager GO achieved an average of 29.67 MB/s write and 111.1 MB/s read - more than double the write speed and nearly double the read speed.

In testing 'real world performance' using several types of file transfers using TeraCopy 2.27 Free, the results are as follows:

-Copying the Windows 10 Technical Preview for Enterprise ISO (3.71 GB), the Voyager Slider had an average of 17 MB/s for a total time taken of 3 minutes, 39 seconds. The Voyager GO transferred the same ISO at a rate of 34 MB/s (double the speed), taking 1 minute, 53 seconds (nearly half the time).

-Copying some music files, 118 -V 0 files equaling 0.96 GB, the Voyager Slider had an average write of 13 MB/s, taking 1 minute, 17 seconds in time. The Voyager GO had an average write of 19 MB/s, taking only 52 seconds. A smaller batch of files, 17 320kbps files, the results were more even: the Slider had a write of 26 MB/s taking 6 seconds, and the GO had a write of 30 MB/s taking 5 seconds.

-Finally, copying 561 pictures and mp4 files (6.45GB in size) taken on my Note II from my synched Dropbox folder to the Voyager Slider had an average write of 15 MB/s taking 7 minutes, 9 seconds, while the Voyager GO had an average write of 28 MB/s taking 3 minutes, 55 seconds.

In other words, the Voyager Slider does a lot better at handling small batches of files at a time, but sustained transfers and/or large file transfers really drag the performance down quite a lot.

The Slider also does not come with a lanyard 'string' (despite having the spot for one), and while it is a retractable, capless design - the actual USB terminal is exposed in the front, leaving dust, dirt, pocket lint, and anything else to easily seep into this socket.

It is also very large. Granted, the size will give it some shielding and survivability from drops, but, it will most likely block surrounding USB ports on your computer. It did fit OK (but barely) in the front USB port of my Kenwood head unit in my truck.

Other Thoughts: The Voyager GO is only $7 more (at this time) and offers (in most cases) double the performance, as well as a smaller size and MicroUSB connectivity for your smartphone. If you're in the market to buy a USB 3.0 drive, I'd definitely recommend the Voyager GO instead of the Voyager Slider.

The Slider is serviceable, but, I think it would be an easier sell if it was roughly $20 cheaper, leaving the GO as more of a stretch/price premium over it.

4 out of 5 eggsNice Flash drive But sub 20MB/s Write speed

This review is from: CORSAIR Voyager Slider 64GB USB 3.0 Flash Drive Model CMFSL3B-64GB

Pros: Cap less design (no cap to loose!)

Descent Read speed (65MB Avg.)

3 Year warranty.

Blue Read/Write LED

Partial Matte Rubberized case for easy grip

Cons: Slow Write speed (15MB Avg.) Losses a star here

Wide foot print (may interfere with near by USB port real-estate)

Poor cap less design. (never stays fully closed)

Other Thoughts: I have MANY Flash drives. I use a lot at work and even more at home. So when using this flash drive I cant help compare it to ones I already own. With that in mind, this drive is not a speed demon. Read speeds are OK. Write speeds on the other hand are not that great. But I like to keep in mind a lot of "USB 3.0" drives these days are not as fast as you might think they should be (this even applies to Portable HDDs) . Its just the reality. When you go to buy a "USB 3.0 drive", unless you are spending big money dont expect much faster sustained write speeds over USB 2.0. Its just the way it is....

I did do some benchmarks for good measure but I really like to do real world test to know what I can expect out of each drive I own so I know what to best use it for. For that I move a folder of mixed files and divide the size of the folder by the time it takes to finish moving.

For this test I used a folder of 13MP pictures and 1080p videos taken from my Note3. The folder was read to and written from My PCs Windows7 Boot drive (a Sata3 SSD). The folder was 13.7GB @ 909 files.

avg speed as tested:

Read: 13.7GB @ 3:37 = 63.1MB/s

write: 13.7GB @ 15:47 = 14.4MB/s

The next day I took this drive to work and did a similar test on a different PC. The File was a Linux ios. It was read to and written from the PCs windows8.1 Boot drive (a Sata3 HDD). The iso was 1.19GB.

avg speed as tested:

Read: 1.19GB @ 0:14 = 85MB/s

write: 1.19GB @ 1:09 = 17.2MB/s

With Both tests I left he Drive formatted as it was out of the box (exFAT @ 128Kb) and I also rebooted the PCs between write and read tests to eliminate any Cache that windows may have stored.


Some other things Id like to note:

The sliding action of this Cap less design is kind of cheap. It will lock in the open position but does not lock when closed. when in my pocket (or anywhere else for that matter) it kind of just half pokes out , not really closed or open. Not sure if mine is defective of if it even matters to most people. Its definitely not a deal breaker for me personally.

Like almost every other Drive out on the market , There is a little hole at the end of this Drive for attaching to your key chain etc. Sadly though you will need to supply your own lanyard or smaller key ring to do this. As the shape of the hole wont allow for a regular sized keying to fit. I really cant wrap my head around why this is par for the coarse with manufactures. Either make the hole big enough for a regular key ring (something everyone commonly owns) or supply a small ring/lanyard with the drive (not something commonly owned). In the big picture im sure it cost less than a penny to include something like this in the package.

All in all this is not a bad Drive. Write Speeds are the only major Con (since they are advertised higher) but I have a few other USB 3.0 Drives that have similar speeds, so by no means is this a "slow" Drive in the arena of Budget USB3.0 Drives.

5 out of 5 eggsPlug it in and it works

This review is from: CORSAIR Voyager Slider 64GB USB 3.0 Flash Drive Model CMFSL3B-64GB

Pros: There isn't a whole lot to say about a flash drive, but these are my thoughts.

The flash drive is 64GB, it can hold a lot. The drive is made of 2 plastics. The outer part is a softer feeling plastic that can handle being dropped, thrown or otherwise abused. The rest is the shiny plastic you are used to seeing with a lot of cheaper electronics.

The blue LED is lit only when transferring files and isn't too horribly annoying which is nice.

The read speed is not too shabby either. The write times are a bit slower with around 17MB/s average on a file transfer. The read times average about 80MB/s. This will be the kind of flash drive to store CD images and other large files meant for redistributing.

As for the average Joe, it works great for anything you could need, store it all and never worry about the space. But please, always keep a backup! We as a people will put more things on it as the capacity grows, but be leery of carrying all your eggs in one basket. See my other thoughts for my recommended application of this drive.

Cons: The write speeds are a bit shocking compared to the reading speed. You can read data at about 80MB/s, but writing is closer to 17MB/s.

The slider design is nice in that there is no cap, but there is nothing to prevent particles and other objects from going in to the connector even with the slider closed.

Finally, if you are not properly lined up with the port, you will simply close the slider instead of inserting the drive. The slider doubles as the grip and if you push too hard or have stiff USB ports, it will become very annoying to keep pulling the slider back.

Other Thoughts: All in all, I would recommend this drive for use by IT personnel for storing and taking ISO images and other large programs from place to place. This is primarily due to the number of reviews that cite failures. I have only had this drive for 1 month and have had great luck with it. But many have had failures and 64GB worth of data is a lot to lose. So always make backups of your personal data!

3 out of 5 eggsCorsair Voyager Slider 64GB 3.0 Flash Drive

This review is from: CORSAIR Voyager Slider 64GB USB 3.0 Flash Drive Model CMFSL3B-64GB

Pros: Good size for backing up files or what ever you need it for
Feels pretty rugged and could withstand a drop
Very Competitive price per size
Recognized in 3 different operating systems (Win7, Win8 and Win 8.1)
5 year warranty

Cons: Definitely not the fastest 3.0 drive I have used as other reviewers have stated.
Although the read speeds are pretty snappy the write speeds are only slightly faster that USB 2.0.

Other Thoughts: The slower speeds is why I had to give it a 3 egg rating plus you can find 64GB drives cheaper and probably faster.
Here are my results with Atto benchmark tool:

Filesize / Write Speed / Read Speed (MB/sec)

0.5 / 208 / 3319
1.0 / 444 / 6243
2.0 / 890 / 12106
4.0 / 1820 / 19359
8.0 / 5184 / 26491
16.0 / 3846 /34942
32.0 / 7858 /38641
64.0 / 9051 / 42010
128.0 / 11883 / 41412
256.0 / 12141 / 41562
512.0 / 12999 / 40184
1024.0 / 12959 / 41110
2048.0 / 14186 / 40108
4096.0 / 14 625 / 41191
8192.0 / 16025 / 78261

In real world situations it starts to write fast around 35MBs then it will drop down to 16MBs or so. Other than the "slower" write speeds I am fine with the drive as a smple storage device and maybe that's what it was meant for.

2 out of 5 eggsGrrrrr......

This review is from: CORSAIR Voyager Slider 64GB USB 3.0 Flash Drive Model CMFSL3B-64GB

Pros: Very fast
Decent price for specs

Cons: USB 3.0 quit working after 9 months. (see other thoughts)

Other Thoughts: This drive quit being recognized in any USB 3.0 slots. Recognized in USB 2.0, just not 3.0. I've tested the USB 3.0 on several different machines. All recognized the drive in USB 2.0, none in USB 3.0.

This is my second USB 3.0 drive from Corsair and both have died/quit working properly in under a year. They have amazing RAM and other products, but maybe USB 3.0 flash drives aren't their thing.

3 out of 5 eggsspeed stick

This review is from: CORSAIR Voyager Slider 64GB USB 3.0 Flash Drive Model CMFSL3B-64GB

Pros: high capacity. inobtrusive cool slider designer. no cap needed

speedy usb3. flash drives have come a long way since the 1gb/2gb/4gb days

tried it in multiple computers and different versions of windows. no problem for system to recognize it

played videos and podcasts off of it no problem. blue led blinks when being accessed

Cons: when you slide it close, the end slinks out a bit, the usb head doesnt stay fully closed

tried to test it and drag and drop a blu-ray movie into it, it wouldn't let me, even though there was plenty of space. maybe this error is on the OS side

I don't think the slider design will stand the test of time

Other Thoughts: I would pay a few more bucks and grab the 128gb capacity. You never know...

4 out of 5 eggs

This review is from: CORSAIR Voyager Slider 64GB USB 3.0 Flash Drive Model CMFSL3B-64GB

Pros: Large capacity
Immediately recognized by all devices tested with
5 year warranty
Fast read speed
Sturdy design

Cons: Slider "cap" doesn't protect from dust or debris
Larger than similar capacity devices
Slow write speed

Other Thoughts: Other:
The formatted capacity is 57.6 GB. It is formatted as FAT32, great for compatibility, but bad for large files.


The write speeds aren't superb. I have older USB 2.0 flash drives that have better write speeds, but that was a selling point on those, not on this drive. The description lists fast read speeds and it does deliver them. I didn't encounter any real issues using this flash drive for small videos, documents, pictures, etc.

5 out of 5 eggsVery good write speeds

This review is from: CORSAIR Voyager Slider 64GB USB 3.0 Flash Drive Model CMFSL3B-64GB

Pros: +USB 3.0 with good read speeds for a flash drive

+No stupid caps to lose, since it retracts back into its own case.

+64GB (57.6GB pre-formatted in FAT32)

+Nice blue led that isn’t an annoying bright light.

+5 year warranty so they must trust their product. If it did have to be replaced it shouldn’t cost much to ship it due to its light weight. Most products don’t come with 5 year warranties.

Cons: -It would be nicer if the write speeds were faster than they are.

Other Thoughts: The flash drive itself is a little fat, but I was still able to fit it next to or above my other flash drives. It has a smooth type of rubber coating on it, and I like the looks of it more than I thought I would.

The write speeds are the only thing that I am a little disappointed with. I have a 64GB microsd card that gets a little faster write speeds. Although the read speeds on this are just as good.

So far I have had no problems with it, and even transferred over 11GB to the drive without any aborts.

Tested on a MSI Z97 motherboard with an Intel 4771 cpu.

ATTO Benchmarks using USB 3.0

Filesize / Write Speed / Read Speed (MB/sec)

0.5 / 217 / 3311
1.0 / 445 / 6590
2.0 / 804 / 12800
4.0 / 1891 / 22755
8.0 / 4035 / 45732
16.0 / 7413 /66609
32.0 / 7481 /68767
64.0 / 13107 / 70014
128.0 / 13696 / 70584
256.0 / 16141 / 76562
512.0 / 15606 / 79184
1024.0 / 16559 / 80010
2048.0 / 18186 / 80129
4096.0 / 16025 / 79891
8192.0 / 16025 / 78261

I won’t type out all the USB 2.0 speeds, but for the largest 8192 file size on USB 2.0 the write speed was 13653 and the read speed was 44369.
