Great flash drive, somewhat tarnished by... tarnish. Edit: drive failure :(

Works great, seems fast and reliable.

Light weight, barely feel it on my lanyard. Quality construction.

The only downside is that it tarnishes very quickly. I have a key shaped, silver usb drive from a different manufacturer on the same lanyard. On day one, they were just about the same shade of silver. Weeks later, the key shaped drive looks like new, while the ADATA unit looks like very tarnished pewter. I actually like the look, but people who bought it for appearance may be disappointed.

I'd buy again, but the tarnish doesn't bother me.

Update: 1/19/2016

Well, this drive started to give me occasional problems a few months ago, where it would suddenly stop being recognized by Windows as a valid drive. I tried multiple usb 3.0 ports and it just will occasionally drop out. Tonight, this problem became severe, as I can't use the drive for more than 5-10 minutes, often less. Luckily, I purchased an even small, more tarnish resistant drive from Transcend a few months ago and was using it as a backup to this drive, in case it finally quit on me.

I've inspected the connectors and there is no issue I can see. I've tried plugging it in firmly, no change.

I noticed that the drive seems to be getting very hot after a few minutes of file transfers, the smaller Transcend drive does not show any heat issues. I'm wondering if there might not be some sort of short or other issue causing this thumb drive to overheat?

Not really worth pursuing warranty service at this point, time to trash it and move on.

I would no longer recommend this drive.

I've had this drive for almost 4 years and today it failed so I'm about to go thru the RMA process.  Overall I've been happy with it but SSD is getting better all the time so maybe its time for a new one anyway.  The new ones are a new generation that uses more reliable technology.  They have gone from TLC to MLC and now SLC.  This drive uses MLC so its not the newest and not the oldest either.  It performed very well and the speed difference between it and a standard drive is amazing.  The next generation of drive will be ReRAM drives in 2018.  They are comparable to DDRAM but the memory is not volatile.  That is so cool.  In the end my advice is to not put too much faith in an SSD just because it has no moving parts and won't crash like a spinning drive.  They do fail! so make your backups!

Bought this drive in March 2014, in Dec of 2014 this thumb drive went from 128gb to 32gb.  Tried reformatting in various forms but without success.  I missed by return time frame.  I really loved this thumb drive and was about to buy another for my wife.  It gets one star because the other one I have is still functioning properly.  The cap is silly as it falls off easy.  Both caps were lost within one week.  The key ring area is very narrow and have to use a tiny one.

Great flashdrive while it worked. I kept it on my key ring like other people who have reviewed the product but I guess that was too harsh for the flashdrive. 5 different computers cannot detect this drive after 2 months. Sad...

I originally purchased this flash drive about a year and a half ago. I was really happy to get so much travelling storage space. I used it for about 3 months and then my computer wouldn't recognize the drive even thought it would recognize my SAN Disk and Kingston drives. The drive over heated in my computer and I contacted Corsair and they sent me another one.

I received the new one and used it for about 6 months and it worked fine. I went to my sisters wedding in May and took over 1,000 pictures which included pictures of my grandsons first visit to Disneyland. So you can just image how upset I was when transferring files from a borrowed laptop and deleting the items from the laptop I went to my computer to transfer the files and again it wouldn't see the drive. After about a half hour of @($&*$#! at the drive a message popped up that the USB port was overheating. I again got with Corsair and was told that they would send me a third drive but that they couldn't retrieve anything off the flash drive and they had no explanation as to why it was overheating in my computer.

Needless to say I am through with Corsair and I'd advise you to be careful leaving these drives in your computer for any length of time.

I'm following up with my original review (below), because I recently dropped my drive onto the floor. The sound of loose parts inside the cylinder was not reassuring.  The drive would no longer come up when inserted into a computer. I carefully opened the drive and found that there was a very tiny black component which had fallen off the circuit board. It looked somewhat like those other black square components (see photos).  I was panicking because I had just used this drive to back up my work before wiping my laptop.  Years of family photos, important immigration documents and many other irreplaceable items were now locked inside the memory chip. To make matters worse, I'm in living in a foreign country and deciding who to trust with my important information made fixing the drive a very risky proposition, but since I was up against a deadline with one of my projects, I decided to try to fix it.  Several stores wouldn't touch it, but one guy at a cellphone repair kiosk added a small blob of solder to join the leads where the component used to be.  After arriving at my office, I carefully plugged it in to my computer and thankfully, the contents showed up, but the drive was very unstable.  It took many attempts to download my data because the drive would frequently disconnect.  I'm guessing the missing component was either a capacitor or a resistor.

Now I'm revising my score to two stars, because a simple one meter drop to a concrete floor while still sealed in the protective cylinder shouldn't have killed my drive.  I really wanted to like this drive, but the reason I bought it over other choices is because I really needed it to be strong and reliable. Now it's a brick.  Perhaps if I have time, I'll send it back to Corsair so they can figure out how to improve the design.

============ original review below ==============
The Corsair Flash Survivor Stealth 256GB USB 3.0 is very nicely made.  I bought it to augment the 64GB version that I bought five years ago.  The speed is very good and the construction is excellent. I'm an ESL teacher. The survivor that I bought five years ago gets nearly daily use in Chinese classrooms on all kinds of old clunker computers and it has never let me down.  The new stealth is great, but for my application, I would prefer it to be a bright color that is harder to ignore or leave behind.  I would also prefer the lanyard attachment on the shell instead (like the old one) because it's my way of reminding myself that it's in use.  The preferable method is to unscrew the drive and leave the shell hanging out.  I never put the shell back in the pocket or bag unless I screw the drive back inside, but the new one has the lanyard on the drive which means I have to leave the shell loose on the desk.

Using Linux Ubuntu and Gparted partition editor, I divided to the drive to have the first partition very large and then I put a small 10GB partition on the end.  In Windows, the first partition with all of my files shows up, but not the second partition.  But if I interrupt the boot sequence, I can boot into Ubuntu 15.10 which has been installed on the second partition and then Ubuntu will also show the first partition with all of my files.

Pros:
Tough construction
Fast performance
Lanyard attachment
Able to be partitioned

Cons:
Lanyard attached to the drive, instead of the shell
Black color makes it easy to lose.

Go ahead and buy this product.  You won't be disappointed.

I really have no complaints about the drive itself.  It's everything it claims to be.  It stores large amounts of data, it can retrieve that data very quickly (espectially if your computer has a USB 3.0 port), and doesn't get so hot that you wonder if it's going to melt.

So why a four-star rating? *(See edit below)

Because, for whatever reason, it may not actually work with your computer.  I used this to backup my media collection on my Linux desktop, then carried it to a friend's house to watch some movies.  Their TV wouldn't recognize it as a USB device.  Their Macbook wouldn't detect it, either.  We did get it to work under Linux on a different laptop that was set up to dual book Linux and Windows.  (It would presumably have worked on that laptop under Windows, but we didn't try it.)

On the other hand, my $35 Raspberry Pi had no problem with it.  Go figure.

I don't know if the problem is with using USB 3.0 on devices with only USB 2.0 ports (although USB 3.0 is supposed to be backwards-compatible, and the RPi's USB port is 2.0) or if those devices had a problem with the size of the drive.  Either way, you should be aware that this drive might not work with you computer, even if it's not a problem with the drive itself.

*** EDIT: I've changed my testing to five stars.  After a bit of poking around, I discovered the file system identifier was set incorrectly.  I don't know if the drove shipped like that or whether it was something I did inadvertently.  However, after fixing this (using either fdisk or ntfsfix -- I don't remember which -- on my Linux laptop) the drive works fine on every computer I've plugged it into.  I would recommend Windows users format the drive before you start using it just in case.  Other than this easily remedied (if not entirely obvious) issue which may very well have been my own fault, this has so far been a great drive.

I like almost everything about this key ring flash drive. A few points to consider that would've gotten 5 stars out of me: a) there should be a 64GB version; b) price is much more expensive that other brands, although quality is really good and it's stylish, made of aluminum and c) orange sticks out so much, they should've included 3 or 4 rubber cases in other colors in the box, at least two more: black and navy.
Using it is really simple and easy, like most usb flash drive sticks. It connects perfectly well to my rMBP and always mounts ok.
Performance is great, as long as you format it to something other than FAT. I did some tests with the format that came out of the box and was extremely disappointed with the reads and writes. So I formatted to Mac OSX and now it is faster than my USB 3.0 portable HDD, as it should. Here's my write stats:
copying 3.76 GB 5,657 files
FAT: 4:21" - 15 MB/s
Mac OS Journaled: 0:57" - 67 MB/s

Update:
I know have three of these and I still love these drives.

Excellent drive.  This is my second.  I was shocked how good the first one was and when I needed a second, I didn't even hesitate in ordering a second.  Im likely to be needing a third very shortly due to a very old drive beginning to fail (not one of these...a WD drive that is 8+ years old

Great drive, but be sure to put it through its paces early to find out if it needs to be replaced.  Not only can the drive be bad, but there could have been an issue during the shipping and handling from Amazon.  Do a full format, run the WD diagnostic tools and check the S.M.A.R.T. readings on the drive.

If it isn't fast and quiet, there may be a problem.  If you're hearing odd clicks from it, that's not a good sign.  If the drive turns itself off after some mild activity, it may have a heating problem or bad drive controller.  The drive should not get hot enough to need to shut off under regular usage, even if your case doesn't have the best airflow.

My drive shut itself off two times about a week apart and it had decent airflow.  None of my other drives have ever done this.  Up until it shut down, you'd think the drive was mint.  WD will be happy to replace the drive for you.

I clocked write speed at about 14 MB/second on windows XP. That's nice. On the downside, it has this incredibly irritating red light that slowly blinks even when the drive is idle! I was ready to take a hammer to the thing until I put black tape around it to hide the light. Now I can't see the light flash when data is read written or read to the drive. Also, it's bulky enough to bump into other USB devices, so you may need to remove them. I did not have either of these problems with my old Memorex 512MB traveldrive, which was only slightly slower.

Great flash drive! super portable (although I recommend attaching a little strip so that you don't loose it; this thing is small!). Only concern is that it gets pretty hot during intensive read/write period (especially when handling big amounts of very small files, which is when the control chips work the hardest). Will see if it fails due to heat

I was really impressed when I received these drives. They really are a great form factor and the all metal design was actually much more impressive than the images show on Amazon. I opened one, plugged it in and tested it out.  The speed of these drives was also quite good for my needs. Crystal DiskMark shows up to 128MB/s Read and up to 12MB/s Write on my system. I opened all of the drives and labeled them with my Brother label maker so they can be prepped for end users at my company. These were for the IT techs to carry around useful troubleshooting tools on their keychains.

  A few days later, I began setting up these drives with the data they required. This is where I ran into problems. I ended up with 3 out of 10 drives that did not work. (2 of them have bent pins inside, and one of them refuses to format). I cant be certain that these drives came with bent pins, but I can be certain that Ive never had USB pins bend or break on me in the 16+ years Ive been using USB devices. Whether the pins bent while I was inserting them (on the first day of use) or they came that way I see some issues here. Either these drives have a design flaw, or insufficient quality control. I pretty much expect the remaining 7 drives to potentially face similar issues once I distribute them to my end users.

  I contacted the manufacturer via Amazon and (after a few days) I was told they have a life time warranty and I should fill out an RMA form. Upon submitting my RMA, I was informed I would need to pay return shipping and send it via Registered post, express delivery, or courier. The cost and hassle for returning a couple of $6 items, hardly makes sense. I decided to cancel the RMA,  trash the broken drives, and mark this down as a learning experience. I saw several other reviews mentioning such quality issues, but as MOST reviews were good I figured I was making a good choice. I would have used Amazons hassle free returns, but since I threw away the packaging on day 1 (like an idiot)  Lesson learned.

  With a 30% failure rate on my first day of use, I cant recommend that anyone buy these drives in spite of the great exterior design. If you still want to take a chance on these, I recommend the much higher capacity drives. At least this way, when you need to take advantage of the warranty, the hassle and shipping become worth it on a $40 or $50 drive.

I like the small profile of the drive but it only lasted 4 months with minimal use before the memory corrupted. I'm hesitant about buying a new one but I've had great luck with Sandisks in the past. This one is being chalked up to a manufacturing fluke.

Great drive, the only reason I'm giving it 4 rather than 5 stars is due to the incompatibility between it and the FRESCO 1100 chipset used on many USB 3.0 cards.  I originally purchased the Inateck KTU3FR-4P USB 3.0 card for my Win 7 64 Bit system.  When plugged in, nothing happened for about 45-60 seconds, which at that point, the device registered with the system, but produced dismal 2.0 speeds.  I went on to purchase the Rosewill RC-508 USB 3.0 card with the Renesas chipset, and all is well now.  All of my devices work (WD portable HDD's, WD powered HDD's, Sandisk Extreme 64GB flash drive, PNY 64GB flash drive, etc.)

The speed of the Voyager GT aren't anywhere near as good (see attached pic) as the Sandisk Extreme flash drives, but better than most and I've always had good luck and reliability from my Corsair USB 2.0 drives, so I expect the same here.

Good Drive. My nit to pick is I hate flash drives with separate caps - way too easy to lose. If there was a way to tether or, better yet, eliminate the cap, I would be in favor of it.

For the short time I had the drive it worked very well. Then it got corrupted (99.5% sure this was my fault) and I haven't been able to use it since.
