3 out of 5 eggsHorrid Write

This review is from: CORSAIR Voyager Slider 32GB USB 3.0 Flash Drive Model CMFSL3B-32GB

Pros: - USB 3.0
* Good read speeds

Total read speeds was 122 MB/s with 0's
Total read speeds was 98 MB/s with randoms
Total read speeds was 104 MB/s with urandoms

It is a tough casing and a protector for the connector.

Rubber feel on the outside is nice.

Cons: Horrid Write speeds

Total write speeds was 28 MB/s with Zeros
Total write speeds was 2.1 MB/s with randoms
Total write speeds was 4.2 MB/s with urandoms

Other Thoughts: I was using NTFS format and DD for the benching

Horrid Write speeds but good read. I used this on USB 3.0

Overall, I would only use this as a backup Flash Drive

5 out of 5 eggsNice Drive for the money

This review is from: CORSAIR Voyager Slider 32GB USB 3.0 Flash Drive Model CMFSL3B-32GB

Pros: Nice design, good price, slide closure, USB 3.0, pretty fast considering, tie loop to tie around neck or ect, activity Led.

TIME // TO COPY Files FROM HARD DRIVE / TO slider drive USB 3.0 ==
3358 mp3 files -- in 27 folders --also 3 AUDIO CD image files TOTAL SIZE OF COPY -- (16.1GB)
(Took 31 min 35 sec From start to finish)

TIME // TO COPY same Files FROM HARD DRIVE TO PNY USB 2.0 ==
3358 mp3 files -- in 27 folders --also 3 AUDIO CD image files TOTAL SIZE OF COPY -- (16.1GB)
(Took 59 min 31 sec From start to finish)

SO FOR THE EXTRA COUPLE BUCKS SAVING OF TIME IS WORTH IT TO ME...

Cons: WISH IT WAS THINNER - No cover for male plug CAVITY – SO just don’t put it in places that can cause a problem like pocket - Activity light on wrong side for my computer – My problem not the slider drive

Other Thoughts: This is not the first Corsair flash drive I’ve owned. I have a flash voyager usb 3.0 for over 2 years now and it still works great. I have read the reviews on both these drives and I find it hard to believe they malfunction so quickly on other people. Maybe there is something else going on. Like let’s be gentle with these things. I have never had a flash drive go bad and at one time I carried 3 in my tool case of course I placed them in a protective case. So before you guys blame the drive think of how it was treated. My personal thoughts of this slider is it’s worth the money and much faster than USB 2.0 -- So I give it a definite 2 Thumbs Up

5 out of 5 eggsGreat 3.0 flash drive so far

This review is from: CORSAIR Voyager Slider 32GB USB 3.0 Flash Drive Model CMFSL3B-32GB

Pros: Good sized flash drive, doesn't get lost in your pocket
No extra software or drivers to install...just plug and play
works with USB 2.0 ports (backwards compatible)
good design, I like the sliding feature, it has a small grip portion to pull in and out the USB port
Has a small loop for keychains which I use a lanyard to keep this flash drive handy
materials seem very sturdy, made of good quality plastic
visible blue light for activity is great
faster read/write speeds than my other USB 2.0 flash drives

I have plenty of USB 2.0 flash drives but this is my first USB 3.0 flash drive I've ever used.

Cons: As usual for every Flash Drive, HDD or SSD's I've ever bought...this one states 32GB but I only got 30.9GB of free space on this flash drive. On top of that it shows at 16KB is being used and that only 28.8GB is available.

Did not get the 100MB/second that USB 3.0 claims to get from either reading or writing.

Other Thoughts: Here's my setup:
Samsung Laptop (Intel i5-3230M CPU @ 2.69GHz, 6.00 GB RAM, Windows 7 Professional 64-bit)
Internal SanDisk SSD 256GB
External Samsung SATA 2.5" HDD connected via USB 2.0
External Corsiar 32GB Flash Drive connected via USB 3.0


Tests #1 to #4 was determine how fast/slow transferring to Corsair 32GB Flash Drive

Test #1 - Read from Internal SSD - write to Corsair 32GB Flash Drive
348MB Data File
Got constant 22 MB/second transfer speeds

Test #2 - Read from Internal SSD - write to Corsair 32GB Flash Drive
2.7GB Video file (MP4)
It started with 45MB/second for about 5 seconds then dropped to 23.2MB/second until transfer completed

Test #3 - Read from External 2.5" HDD (USB 2.0) to Corsair 32GB Flash Drive (USB 3.0)
459MB Data File
It started with 30MB/second for about 2 seconds then dropped to 14.2MB/second until transfer completed

Test #4 - Read from External 2.5" HDD (USB 2.0) to Corsair 32GB Flash Drive (USB 3.0)
1.71GB Video (MP4)
Transfer speed 32MB/second for 5 seconds then dropped to 13.9MB/second until finished transfer


Tests #5 thru #8 was determine how fast/slow reading from the Corsair 32 GB Drive to another destinationd


Test #5 - Read from Corsiar 32GB flash drive and write to Internal SSD
348MB Data File
It started with 48MB/second for about 2 seconds then dropped fluctuating between 41.0MB/second ~ 42.5MB/second until transfer completed

Test #6 - Read from Corsiar 32GB flash drive and write to Internal SSD
2.7GB Video file (MP4)
It started with 42MB/second for about 5 seconds then dropped fluctuating between 21.1MB/second ~ 24.3MB/second until transfer completed

Test #7 - Read from Corsiar 32GB flash drive and write to External HDD (USB 2.0)
459MB Data File
It started with 46MB/second for about 3 seconds then dropped to 15.6MB/second until transfer completed

Test #8 - Read from Corsiar 32GB flash drive and write to External HDD (USB 2.0)
1.71GB Video (MP4)
Transfer speed 32MB/second for 2 seconds then dropped to 13.9MB/second until finished transfer

What I got from this test:

Read speeds from Corsair 32GB Flash drive varied between 22MB/second to 45MB/second
Write speeds to Coarsair 32GB Flash drive varied between 21MB/second to 48MB/second

My thoughts: get this if you need a 32GB flash drive with faster than USB 2.0 transfers...on the other hand, if you need faster transfers USB drive maybe wait until the technology is better where they are reaching 100MB/second transfers.

5 out of 5 eggsI Think it's a sturdy Speed Demon

This review is from: CORSAIR Voyager Slider 32GB USB 3.0 Flash Drive Model CMFSL3B-32GB

Pros: Solidly built with a firm gripping body.The Slider works perfect and offers good protection for the usb connector.
Speed is perfectly adequate transferring files usb 2 mode.Tho why use usb 2? When hooked into a usb port this baby works like its an sdd.

Cons: I hope i don't lose this one lol

Other Thoughts: Speeds in USB 3 peak at 70MB/s and average in the 40s for a large file.Copying a large mixed program file is somewhat slower 10 to 25MB/s.Plenty fast.

2 out of 5 eggsStopped working

This review is from: CORSAIR Voyager Slider 32GB USB 3.0 Flash Drive Model CMFSL3B-32GB

Pros: Fast enough speeds. As expected.

Cons: I've owned this drive a couple months short of a year. It's always been stored nearly on my desk, hardly touched. I used it a total of 3 times in it's entire life span before it just stopped working last week.

Other Thoughts: I'll definitely be spending the extra cash and buying more reliable flash drives in the future. I'm very disappointed in this drive.

1 out of 5 eggsSad...

This review is from: CORSAIR Voyager Slider 32GB USB 3.0 Flash Drive Model CMFSL3B-32GB

Pros: It works fine.

Cons: Only last for 4 months.

Other Thoughts: It died after 4 months. I sent RMA and got reply very fast. But the new one cannot be detected under USB3.0, only works with USB2.0. POOR quality. I have some other flash drives from Kingston, Patriot, and Sandisk, never have any issue.

1 out of 5 eggsLook elsewhere for reliable USB 3 speeds

This review is from: CORSAIR Voyager Slider 32GB USB 3.0 Flash Drive Model CMFSL3B-32GB

Pros: Size for the price is reasonable.
In general the design is not bad, even rugged (with some exceptions. See Cons)

Cons: SLOW. I cannot put enough emphasis on this one. It's not USB 3.0 Super Speed, even though it's a USB 3.0 USB drive.
When I get a new drive I use H2testw to check speed (as well as for any errors and reliability). These are the speeds I got.
Writing speed: 16.2 MByte/s
Reading speed: 72.0 MByte/s
For anyone unsatisfied with my results using H2testw I also used ATTO and got the same results.


The slider cap is a bit loser than previous models. It feels slightly cheaper made compared to an older Slider I own. It's still pretty sturdy, but it just doesn't compare to the older one.

"B version". Stay away from any Voyager Slider drive with the CMFSL3B model number. The "B" version completely killed this drive.

Other Thoughts: I'm extremely disappointed with both Corsair and this USB 3 drive. I wish I could return this USB drive but that's not feasible. It's not worth dealing with any restocking or shipping fees.

Corsair's quality control and it's business practices towards customers (which I discovered by doing research AFTER finding out the poor performance of this USB stick)

Months ago I bought a 16GB Slider. It has the model number CMFSL3 (notice no "B"). Drive felt very well made and the slider is just tight enough that it won't accidentally slide down and expose the USB connector.

Speed tests using H2testW are listed as:
W: 22 MB/s R: 50 MB/s
I also used ATTO for comparisson and recieved similar results.

Advertised speeds (which are actually readily available for this model, unlike the "B" revision) are:
W: 20MB/s R: 70MB/s


Now as for the 32GB drive

If you look at the specs page the read/write speeds are not listed (unlike previous versions), but when you find it they are listed as
Read up to 80 MB/s
Write up to 40 MB/s

As you can see the write speed I got is FAR off from the advertised specs of 40MB/s. A newer model 32GB USB drive should be FASTER than a slightly older 16GB drive. NOT SLOWER. IMHO a USB 3 drive has to deliver AT LEAST 20MB/s write to be satisfactory as a USB 3 device.

I believe that Corsair is being dishonest with it's customers by not only failing to deliver USB 3 speeds but also being AWARE of this issue and not doing anything to address it. I found a lot of complaints about the CMFSL3B drives and even found some horrifying evidence on Corsair's own forums. Corsair's own tech support has said that CMFSL3B drives ARE SLOWER than the first gen CMFSL3 drives and CMFSL3 were discontinued because of availibity of components.

Also I had to laugh when I noticed on the package it "USB 3 High Speed". This actually should be a clear red flag. "High Speed" is actually USB 2 spec while USB 3 is "Super Speed".

What irritates me is that Corsair is essentially selling a USB 2.0 product disguised as USB 3.0. This is being dishonest to US, the consumer/customer. First gen Sliders were better made and faster. This new version fails to deliver and instead of fixing it they are just hiding the facts from us.

In Cons I mentioned lower quality. I decided to weigh the 2 drives and this is what I got.

16GB drive = 13.7 grams
32GB drive = 13.0 grams

If your wondering "Why weight?" it's because weight can be used as an indicator to tell wether cheaper or more quality materials (eg. plastics) were used in making the product. The fact that the CMFSL3B 32GB drive weighs slightly less than the older 16GB may lend weight to the fact that the drive does feel more cheaply made (See what I did there?)

My closing thought is NO. Don't buy this drive. Don't buy ANY Voyager Slider drive with the CMFSL3B model number. Stay far away from them.

Shame on you Corsair.

1 out of 5 eggsHorrible experience - EDC beware

This review is from: CORSAIR Voyager Slider 32GB USB 3.0 Flash Drive Model CMFSL3B-32GB

Pros: Decent speeds

Cons: Not sturdy at all, this little metal part of the USB connector sticks out. Absolutely horrible for EDC.

Other Thoughts: During the ice storm in the East lately, I was doing some work with this in my front usb 3.0 header. The power shut off, and I was without it for 4 days. I left the usb in my computer thinking "Ah screw it, nothing I can do with it now" and ejected it this afternoon. The metal part bent on a 45 degree angle, and I had to bend it back. The weight of itself actually made it bend, and that's dissapointing.

The USB connector sticks out, so if you try to wear it on a keyring (good luck getting it on there anyways, little hole is too small for a decent strength ring) it's going to constantly hit around your keys.

2 out of 5 eggsGo with the non-slider

This review is from: CORSAIR Voyager Slider 32GB USB 3.0 Flash Drive Model CMFSL3B-32GB

Pros: Corsair... so I would hope it lasts

Cons: USB port is exposed even when slid in, no cover for it.
Lighweight, feels cheap.

Other Thoughts: Coming from the "CORSAIR Flash Voyager" that broke after a few years, I thought I could expect that kind of quality. This is not it. The keyring holder is made of plastic, thats bound to break off. (Maybe its not for keyrings) But I don't feel comfortable leaving in my pocket knowing the dust and lint can get into the USB socket because there is no cover for it. It just slides in.

I expected better from Corsair. Spend the extra $3 and get the CORSAIR Flash Voyager. Model: CMFVY3S-32GB I wish I did.
