Fast. Small. Works Dual Nicely. Very hot though.

Fairly fast and small. However, it gets freekin' hot after some minutes of saving data to it. Actually a bit too hot to touch.

Excellent mini PC! Super fast; super small! Runs a bit hot, so I also bought a mini fan:

They work great together... and super quiet too!

First off, what everyone else is saying about this thing getting hot it very true. I didn't believe them at first or thought they were over exaggerating, but no, they were right. After it's been used this thing gets HOT! I'm talking at least twice the heat given off a laptop after hours of use. I don't fear that it will cause and damage to anything, it's just shocking at the amount of heat this thing can produce.

Now, other than that, this thing is excellent! Its super small, has a large capacity and is VERY fast, when used on USB 3.0 devices of course. My last one was a 2.0 and it maxed out at around 8Mb/s whereas this one has gone up to 33Mb/s in some cases, though most of the time it is around 20-24Mb/s. So what used to take about an hour to transfer now takes just a few minutes.

Overall, I am very satisfied with this product and would recommend it and would most likely purchase again, even with it getting as hot as it does.

Great little device for laminating documents, ID cards, etc. Works well and quickly, though I find it also runs quite hot to the touch.

Small an almost unnoticeable when plugged (other than flashing read/write light of course). Performance is quite good, but I did not take time to get exact numbers. Fits snuggly in port (good), but difficult to extract due to such limited space to grab it; it's size is a plus and minus. Very concerned about the plastic top just coming off; it requires that much force to remove. I needed this to do a OS upgrade on a new Intel Skylake system that no longer supports 2.0 devices; required for some types of windows installs. It was overkill, but I plan to use it as a transfer device in the future. It worked fine for my purpose. Extraction was the only problem experienced. Install speed was very fast.

I would have preferred one that had slightly lager case for my purpose of eventually moving from machine to machine.

I bought this to be a portable backup for my work computer. It has served the purpose well. I like its firewire capability, as it can now serve as bootable drive in an emergency. It has enough storage space (for me, at least) to partition into two drives and to use one as backup and one as a general shuttle drive. The only complaint I have is that it gets extremely hot - so hot, in fact, that at one point during a long backup (~60 GB), I thought it was going to burn the table. It can definitely get too hot to hold when in use. However, that's the tradeoff for such a small drive... it weights significantly less than a pound and can easily slip into a side pocket in a backpack or even fanny pack. All in all, I highly recommend this drive.

Be warned, this guy gets rather hot under load. It performs remarkably quickly (as would be expected from Intel's 4th generation of processors) and the HD Intel Graphics are nothing to sneeze at. Unfortunately, this particular processor is very prone to heating up rapidly. While I'm not personally bothered by it, it's something to take into consideration.

Everything else works great! Quality of the tablet, and the amount of power (processing and battery!) it packs into the form-factor is nothing short of spectacular.

This thing is silent, fast and has a turbo button.

Running nicely dual boot with Windows 8.1 and Ubuntu.

16GB PNY 1600 RAM works flawlessly, 2.5" SSD rails made installation a snap. You can also use your mouse in the BIOS which was cool.

The speeds are pretty fast, compared to all the 8GB ones I have. I think, anything cheap will be slow. I spent more than it's asking price now back a couple years ago. (You purchased this item on October 17, 2014.
Capacity: 128GB | View this order)

It still works, but I haven't used it for over a year after I bought it. It was to be used in my car for music files... But, I was too lazy for that.

Anyways, I tested the speeds and it was fast.... Very fast actually..

But, you have to remember, if you transfer over large files, it will go fast... If you have 5000 files that is just 4GB... There are just too many small tiny files there.

The reason I gave this 2 Stars is because, when I transfer over large files, like game files.... Like Mortal Kombat X.... Which is 42-52GB (forgot which), this thing kept stoppping and giving errors... I split up the stuff I needed to copy over. The thing is, it failed on me so many times, I reformat, did another format like NTFS/FAT etc... Nothing helped.

I believe, it failed due to the heat. This thing BURNS you. The metal on this will cook an egg. So, be careful when pulling this out during copying or after it has finished. It will be very hot.... I think, my laptop or whatever stops this or the stick itself shuts down to prevent it from melting.

This is for copying files over. It doesn't have to be large, as long as it takes a few minutes, it'll heat up.
Reading from it, there's no issue. Now, I just copy large 4k movies onto it, yes, it does get hot, but it's just 1-2 files at most. Which are large, but I can get it done before it melts. I have it in my TV, no issue watching the 4K content or 3D movies. No heating issues either, but then again, I didn't pay attention, I am only assuming it will not get hot from read.

Bought this as a lightning deal. It works very well. Super fast. And don't worry if you leave it out, it will shut off on its own.

I really like this little drive.  It's rock solid, and small without being tiny.  I've been using this to transfer some of my film work (~12GB files) from site to site, and it works wonderfully for this.  It copies so much faster than any of my older USB sticks, and of course the capacity is certainly impressive.

The one thing that worries me though is that I put this in the usb port, make the copy (which takes only several minutes), then eject and pull this flash drive out.  And it is hot to the touch!  Only after a few minutes of use.  Owch.  For my use this is fine, but I'd be worried if I was contemplating using this like a regular disk and just keeping it plugged in and accessing files for a prolonged period of time.

Very nice, good speeds (89 read)
Gets kinda hot, which is why I gave it 4. I'm glad it's aluminum, but it gets really hot to the point where I had to leave it sitting on my desk for a minute before i put it in my pocket.

Other than that, it works as advertised, it's not big (tall, so if you have stacked USB it sucks)
Doesn't have a LED on it, which is strange, but not a big deal for me

Works very well and as advertised. Runs pretty *&%$ing hot though. But as long as it keeps kicking no worries for me.

Well, these were purchased to replace some garbage from INNOVITED... So far, so good! They have terrific power ouput. HOWEVER, they get blisteringly HOT... I haven't driven too much at night, and am quite worried about the heat... I am impressed with the initial ignition... Its really quick and gets to full brightness in a matter of 2 seconds!!!

Reader is pretty fast, but runs quite warm. I can't leave it in the computer for very long before it becomes uncomfortable to touch. Probably okay if you are going to plug it in, read/write data then remove it immediately. I wouldn't recommend leaving it in the computer for long periods (which I frequently do with other USB flash memory products).

EDIT (2016/11/04)
I've been using this for a few months now, and while I'm still not comfortable with how warm it gets during use, it hasn't caused any problems so far. Note that I do not leave it in the computer. I just plug it in long enough to transfer the data I need then remove it.

I must say the speed of this thing is impressive. I own a few USB 3.0 card readers, and this is the fastest. Of course you'll need a very fast Micro SD card to see any difference. It won't magically make a slow card fast.

I'm tempted to raise my rating to 4 stars, but I'm still unhappy with how hot it runs. I also don't like that it doesn't have an activity indicator LED. All removable storage devices should have that (in my opinion).

This is SUPER FAST, I mean, I have LOTS of Flash Drives... tons of them... and this one outperforms them all.

HOWEVER...

This will also get SERIOUSLY HOT. It can burn you! So my advice? Buy it, LOVE it... but when you transfer LOTS of files or LARGE files, let it cool off a bit before you remove it from your computer so you don't burn your fingers. This is usually only a problem with WRITING to the drive. Reading only seems to make it warm...

Works great as medium to quickly transfer or copy files. It's quite fast too. However, it get extremely hot plugged in, and it's not suited for constant reading/writing storage.
