5 out of 5 eggsOne year later, still going strong

Pros: All things mentioned in my previous review.

Still going strong after a year with minimal speed loss. I don't know how many times I've re-partitioned and reformatted the thing. It's also been on my key chain constantly for a year.

used the drive frequently, never had any issues

Cons: Slider mechanism doesn't get any better with time. I might as well just leave it open. Considering just removing it.

Other Thoughts: A year into use, i'm still happy with it, and it' is my primary USB drive. 90% of the use is for installing operating systems on various machines that I've setup. It does that task very well, among others. I'm improving the review to 5 eggs because although the slider doesn't stay closed, it hasn't caused any problems a year into it's use, and I use it a lot.

4 out of 5 eggsGreat drive so far

Pros: Seems pretty fast, even when connected to a USB 2.0 port. Good physical size, not overly clunky I guess. The friction mechanism seems to work when extended, I haven't had it close on me when trying to push it into a USB port, like some other friction drives have.

Cons: Seems like it's chunky for no reason. It could have been made at least a little smaller or slimmer.
Keychain spot is made of very flimsy plastic! Not only that, but the space is very small and I couldn't get it on a standard size keychain. It won't slip over both loops so it sits in the middle and hogs up the keychain opening. I wish that had been thought out a little better.

Other Thoughts: Can't wait to connect it to USB 3.0 and see the faster speeds.

5 out of 5 eggsAll Stored Up

Pros: In my previous review I told you that I Love the size of this drive. Well I am still loving it and using it as I go to school at night. It contains all my course work and I haven’t had one problem with this flash drive since I started using it. I have really noticed that the design of this flash drive and it is a great design compared to other sliding drives. I have a problem with the others as they tend to slide back into the protector case and not into the USB port on the computer or extender cord. I have to say that it is a sturdy and firm design that allows you to have all your important files in your pocket and they are easily accessed. I cannot say enough about this drive and its usefulness. If you are looking to purchase a 3.0 USB Flash Drive of the slider variety then this should be your drive. I have a total of 12 USB drives and this one (Corsair Voyager Slider 64GB 3.0 Flash Drive) is the one that I have abandon the other drive for as my favorite and frequently use it on a daily basis. When giving class presentation there is no hesitation when switching from one presentation to the next…to include video and music. Yes, it is large enough and fast enough to hold video and music without downloading the presentation to a host computer…great drive. I still recommend this drive tremendously.

Cons: None.

Other Thoughts: This drive can be used in many different ways. School, work, and even to transfer your music or video collection from one computer to another. If you have those valuable photos that you want to put in a fire proof box for safe keeping this drive does not take up the space require for SSD or SATA portable drives. The Voyager would be perfect for that type of storage. I will purchase these for my grandchildren this year for school and their scrap book hobby. This is a great buy.

5 out of 5 eggsSpeedy but bulky

Pros: Well made, fast and small. USB3 speed is good mostly. I tried it on a desktop using a front panel USB3 connection. Transferring one large 2 gig file was 52MB/s from the key to the hard drive and 45 MB/s from the hard drive to the key. On an Intel i5 ultrabook the speed was identical both to and from. USB2 speeds on the desktop were 30 MB/s from the computer to the key and 26 MB/s from the key to the computer. To put that in perspective a 2 gig disk image took approximately 45 seconds to transfer from the hard drive to the key on a USB3 port. I have a very slow OCZ Diesel 4 gig USB2 key where that same transfer takes over 3 minutes. To me that’s a good speed increase.
This is one of the few keys I’ve owned where file deletions were almost instantaneous. Also I can remember 10 years ago when I paid $250 for a 1 gigabyte SCSI hard drive. Now I have over sixty times that much capacity that I can carry around in my pocket that’s more reliable and a whole lot faster.

Cons: I tried copying a 1 gig folder of MP3s to the key from my ultrabook and the USB3 speed was much much slower, averaging from ½ to 25 MB/s. But that’s not a real knock at this key because most of them are hopeless copying lots of small files. Also the body of the key is bulky and blocks one of my 2 USB3 ports on my ultrabook.

Other Thoughts: This comes in one of those irritating plastic containers that you have to take the scissors to in order to get open. Inside is a nicely made USB 3 key that has a sliding cover that you won’t lose. The cover part is coated with a rubberized coating that makes it easy to handle. Be aware this key isn’t particularly svelte; this key is approximately an inch across and a half inch thick. It does have a small loop for a lanyard but none is included. This little guy seems really amazing to me. The formatted capacity is approximately 60 gigs and it’s dawg gone fast, not to mention I can slip it in my shirt pocket. For the money this is good deal for a key from a company with a good reputation.

5 out of 5 eggsNice. 64GB.

Pros: Capless design. I like this because I tend to lose the caps of any other USB flash Drives. With this one I do not have to worry about that. Only thing to worry about is getting pocket lint in the USB connector.

USB 3 transfer speeds are pretty good averaging about 75 MB/s write and about 90 MB/s read speeds. This was calculated using the Windows 8 built in copy dialog box.
This was also reading and writing to a SATA III SSD Drive. I have not tested this with a standard hard drive.

USB 2.0 copy speeds are not bad either averaging at about 23 MB/s write and 30 MB/s read. Actually a whole lot faster than most first gen sandisk cruzers.

Cons: Only con I can think of is the USB stick is pretty thick. If you got a laptop that has 2 USB ports one on top of each-other, then that would make the second one inaccessible. Same would be if the 2 USB ports are close together sideways, it is slightly wider than most USB flash Drives.

Not enough to deduct an egg though.

Other Thoughts: Overall is a nice drive. Can't go wrong with 5 year warranty. Hope I don't need to use it.

If you need a fast USB 3.0 flash drive that is 64GB and is capless, then this is good. If you worry about the fact that your USB ports are sitting close together, then look elsewhere as this will block one of those ports.

Preformatted to FAT32. I had to reformat it to NTFS since I have ISO and MKV files larger than 4GB.

5 out of 5 eggsNo bells and whistles but works great so far

Pros: 64GB storage
incredibly fast USB 3.0 speed; even at USB 2.0, the write speed is faster than my other flash drives
backwards compatible for use on USB 2.0 ports
does not use a cap, so no extra pieces to misplace
feels sturdy and durable, yet very light in weight
nice blue indicator at the tip of the slider
there's a hole at the tip of the slider for the lanyard

Cons: The size of the flash drive is a bit larger than others I've owned, especially when the drive is in the "closed" position. The slider makes it seem bulkier. And the thickness of the drive becomes an issue when you have usb ports that are very close together.

The slider is not a great design. It can be pushed open by accident. Sometimes when I'm trying to plug it into the usb port, if I'm holding the sides of the flash drive, it starts sliding back closed. It's a bit of a nuisance but not enough to deduct an egg.

Since this is Corsair's simple flash drive with no security features, it doesn't come with any software either, like the SanDisk U3 LaunchPad software which allows you to set security on the entire drive. I like security on my flash drives, so I ended up using TrueCrypt, which works very well on such a large capacity drive.

Other Thoughts: The flash drive is preformatted FAT32. Since I have files larger than 2GB, I had to reformat the drive to NTFS.

I wasn't sure how I could tell if the flash drive was actually using USB 3.0 or USB 2.0. If you know that your pc has USB 3.0, plug the flash drive into the 2.0 port and you should get a message that the flash drive can run faster on a high-speed USB 3.0 port. If you plug it into the 3.0 port, you should not get any messages. I tried this on a pc that DOESN'T have a USB 3.0 port and I didn't get any messages, so I guess the OS knows that whatever port you plugged the flash drive into is already the fastest port you have.

I ran some benchmarks, which were performed on a pc with Intel Core i5-2500k and 32GB of ram. The USB 2.0 averaged about 24MB/sec write and 33MB/sec read while USB 3.0 averaged 71MB/sec write and 91MB/sec read. I ran some benchmarks on a second pc that doesn't have USB 3.0, the pc was a slower machine overall, but I got some interesting results. The USB 2.0 averaged about 30MB/sec write, slightly faster than the first pc.

5 out of 5 eggsAlmost a portable hard drive

Pros: -Unbelievably fast! I'm not sure what happened with some of the other reviewers, but in my situation, through USB2, read/write speeds were pegged at 35MB/s (fastest I've EVER seen through USB2), and through USB3, read speeds were 87MB/s (Windows file copy, and ATTO disk benchmark) and write speeds were 72MB/s. First drive I've seen that exceeds manufacturer claims, which I think is awesome. Honestly, this is pretty much 5400RPM hard drive speed range. I actually think my USB3.0 card hit its maximum before this drive did.
-Good at small file transfers. Groups of small files used to bring flash drives to their knees, begging for mercy, but in transferring small files, this drive actually outperforms my 7200RPM hard drives (as well as all my other 10 or so flash drives).
-Huge capacity. This is news to no one, I'm sure, but it really is amazing how much space is crammed into such a tiny package. The high transfer speeds mean that it's usable space as well. I have plenty of slower high capacity drives that take a half a day to fill up. Not this one!
-5 year warranty. I don't expect to use it, since flash drives tend to get replaced or lost long before they start to die. Case in point, I've personally owned and used over 3 dozen flash drives over the years, none of which have died on me. Still nice to have the assurance though.

Cons: -Kind of a goofy design, in my opinion. The slider thing doesn't really lock in either open or closed position, so it kind of just moves around. If it's in your pocket or purse, don't expect to be able to keep it closed unless you put a rubber band around it. Not worth an egg deduction though.
-It's also rather large. Not exorbitantly large, as I have plenty of other drives that are the same size or larger, but I also have plenty of other drives that are much smaller. To be fair, they're also much slower. Also not worth an egg deduction.

Other Thoughts: USE A USB3.0 PORT! USB2 hamstrings all high-performance drives, across the board. You might think that USB2 would perform just as well under certain circumstances (batches of tiny files), but in literally every single different test, USB3.0 is at least 2-3 times as fast. If you don't have USB3.0, this will still be a fast drive, but you really should have a 3.0 port to let this puppy breathe.

This is an insanely fast USB3.0 drive. I'm sure there are faster ones out there, but I've tested more than a few, and this is the fastest I've seen yet.

3 out of 5 eggsDecent, but slow on writes

Pros: Just to start with the frivolities, I rather like the slider aspect of it because it gives me something to pull out of my pocket and fiddle with when I get the urge. I also kind of like the weird vaguely rubberized yet lubricated substance used on the outer shell. I'm not sure either of these things have any practical point, but I do like them.

As far as the drive itself goes, it's USB 3.0, which is nice, and the read speeds are pretty decent - 55 MB/s to 95 MB/s depending on the file system and access pattern in my testing. I'd say 80% of the time its read speeds are 80 MB/s or faster. In read-only testing access times were close to 1 ms.

5 year warranty is also quite nice. It's rare to see a real warranty on anything these days.

Cons: It's a bit bulkier than I care for. Not worth even an egg, though. If you buy this and don't realize it's a bit fat you're pretty clueless.

The real con for me is write speeds. They're inconsistent, and oftentimes horrendous. I really wish I could post a graph - it'd show a sawtooth oscillating wildly between 10 MB/s and 70 MB/s (averaging to a lovely ~17 MB/s). The benchmark that takes maybe 1 minute for reads takes 6 for writes. In my first testing it seemed like this only kicked in after the device was ~60% full, but it now seems to do the same thing even when mostly empty.

In my more practical real world testing it would seem to write at rates of ~55 MB/s for a good chunk of time, then hang for 10 to 30 seconds, then start writing again.

Because the behavior was so weird I can't completely discount the idea that it may be some specific hardware/driver problem.
