Very small drive. Read speeds close to advertised. I got sequential reads on the 256GB drive in the low to mid 290s MB/s. I got write speeds just under 60 MB/s (sequential). I'm getting random read and writes between 13 and 15 MB/s. See screen shot from Crystal Disk Mark 6.

Write speed was not advertised - specs just say "write speed is lower than read speed". Yeah, less than helpful. I'd prefer to have the write speed advertised so that we can make a more informed purchase. I hope my test helps you all out.

At this price point and for a drive so small I'd say this is a decent purchase. You get huge capacity in a small form factor with write speeds that are in the ballpark of the SanDisk Extreme Pro. If you don't need to consistently write large files - this may fit the bill. If you need faster sustained writes, don't mind a larger drive, and have an extra $35 - maybe the SanDisk Extreme Pro is for you.

These drives are very fast but do run a bit warm. One thing to be aware of is the width of the head. Because the keychain loop is on the side instead of the front, they are slightly too wide to allow 2 or more drives to be inserted into an inline hub, such as a sabrent 4 port USB 3.0 hub with the individual port switches, without having to insert them at a slight angle. They will fit but are not in a flush straight line. If you are using a hub that stacks (not inline) ports on top of each other, this is not an issue.

Unlike SanDisk's **FAIL** in this same space with their recent new one, this has a metal body and seems to be more responsive, etc. over the other. You're better served with this one over the other brands there on this.

This is still tickin-kickin' after three weeks of use as my external store on my NVidia Shield TV unit- SanDisk's comparable? Plastic case (which I was dubious about) welded around the circuit board? Baked itself to death in only a week's time. Get this one, folks- same rough price, slightly faster, and a hack of a lot more robust.

I have over 14 thousand photos and wanted to both have them available to work with on a smaller Chromebook that could be easily transported as well as having a back up should something happen to the main computer on which the images were stored. I had put part of them on a mini SD card which was "top of the line" for speed and is still the smallest storage device around, just a couple years ago. It took FOREVER so I ended up transferring only the parts I would be working with that week. 256 GB will hold a lot!
After a lot of research and reading reviews, I thought this Samsung product would be the best for my uses. (Particularly as it was going to be used in a Chrome book which needed increased memory to function completely for my purposes.
I am simply shocked at how fast this device transferred from my laptop all those photos. It is simply so easy to use. Personally I didnt find the size once plugged into my Chromebook to be overly large. It is about the same size as the doodad used for the bluetooth function on my mouse.
My laptop had both 3.0 and 2.0 USB ports. For the heck of it I transferred data from both ports. Definitely the 3.0 port is noticeably faster. Sometimes when the super computer literate do reviews they provide information on speed, but I don't know if the difference is really noticeable by anyone other then to that high level reviewer. The time difference is vastly improved and you will notice the difference.
I just downloaded a 9 hour video this morning and again I was so shocked at how quickly it downloaded. If you download movies for your children to watch on trips, this device is a most have as it will allow you to do so quickly. Plus the storage capacity on this is wonderful.

I bought this for the usb port in my car to hold music instead of packing around my binder of cd's. It was a little tricky to load on my computer to begin with. Had to use the port in the back of the tower. However, once that got sorted out loading it was easy and fast, even loading whole cd's. It holds alot of music, *alot of music*! It registers with my car really fast so there isn't alot of wait time. It's low profile, doesn't get in the way of anything at all, most of the time I forget it's even there. Very well worth the price. Would order it again.

I was a big fan of the prior version, and bought a few of them. The new version is faster and cheaper, but also much larger. Samsung took a unique product and sacrificed what made it great.

The new Fit Plus has more capacity than the previous Fit version but at the expense of a larger head.

My love of the previous version is based in large part to that flusher fit. I use these in laptops where a USB drive sticking out from the computer can be a leverage point if dropped or bumped.

I don't check the speed via any software but know it is plenty fast for my usage.

This thing is tinywith a very unobtrusive footprint which is great (especially for use in cars). If you are going to load music on it for your car, I recommend checking with your car manufacturer either in the user manual or online using make/model/year of your car and the search term "USB file format". Some vehicles read FAT32, some read exFAT. It's important to know else your car won't be able to play the music. This samsung drive is EXFAT. but don't let that dissuade you from getting this drive since you can easily reformat the file system with a computer and free file formatting software. Read/write speeds are fast and it feels durable. It does not come with a cap. I deducted one star for the hole where one can attach it to a keyring since the space is too narrow. Samsung should have included a small enough ringwith the drive.

In my case this 64GB device is working great. Less noise on 2.4GHZ than others I tried and that means I can use my wireless mouse now (someone should have caught that before USB 3.0 was made).

No heat if just left in (some will get hot just by being in the plug).
No heat issues as I moved @30GB to it.

To give a historical idea on temps and devices..
A good 80GB harddrive from the late 90s before SSD would like to run less than 40C 104F.
Many new device CPU's on the High performance side have a thermal shutdown at 90C-100C (194F-212F or boiling point of water).

So far this flash drive ran the cooler of what I tested including some SDcard to USB 3.0 options.
Only one adapter won the temp test as VERY cool. SanDisk MobileMate USB 3.0 microSD Card Reader - SDDR-B531-GN6NN won the heat test hands down. But lots more noise in the wireless band for a mouse and keyboard.

I still keep a finger near the Flash drive only because so many talk of heat and fear.
But so far it looks like I have a brand I can use as all tests even for data loss under load all passed and very low heat and RF noise in a USB 3.0-3.1 port.

I really like this thumb drive, large capacity in a very small footprint. You have to question why other manufacturers can't match it. It's after all not all that hard. Could it be because most others are all made in china and there's just no innovation, but all for profit. I think so. Good item, although I couldn't get it to work on my car stereo, which is what I got it for. My car head unit only accepts usb2.0, while this thumb drive says it is 2.0 compatible, it does not work on my Alpine head unit.
