SAMSUNG FIT Plus 3.1 USB Flash Drive, 128GB, 400MB/s, Plug In and Stay, Storage Expansion for Laptop, Tablet, Smart TV, Car Audio System, Gaming Console, MUF-128AB/AM,Gunmetal Gray

This SAMSUNG USB thumb drive (256GB) is FAR superior to the Sandisk next to it (512GB). The Write speed is MUCH faster than the Sandisk by tens of minutes (copying the same data). THE BEST PART is the outer shell of the SAMSUNG drive acts as a heat sink. Modern USB drives can get VERY hot (but not dangerous to touch). The SanDisk USB’s outer shell is plastic. This is worrisome, as the internal microchip could deform as it heats up. If that happens, say goodbye to your data!!The sell page for this SanDisk product says “up to 400MB/s (Based on read speed.” WRITE speed is what is important on USB sticks and that is MUCH slower than that. (This is kind of misinformation. They need to display read and write speed). The SAMSUNG outperforms the SanDisk every time.Also I am no longer a SanDisk customer as I have bought 6 SanDisk External Hard Drives up to 6TB, and they have ALL CRASHED!!I am BEGGING SAMSUNG to release 512 an 1024GB versions of this as it is the most superior thumb drive out right now. It’s a little more expensive than the SanDisk equivalent (or another vendor, per GB), but you pay for what you get.Quality product.

This is a USB-A thumb drive (the older and more universal format).Some people may need a USB-C thumb drive if your device has no USB-A ports.(In that case I recommend the Samsung MUF-256DA/AM for about $5 more but this is the drive to buy if you have a USB-A port).I love the size–the drive extends only a few mm when fully inserted.It’s also incredibly fast, easy to insert and remove, and has a hole for a lanyard or keychain.NO USB-C thumb drive can fit this compactly.NO USB-C thumb drive is anywhere near this small.NO USB-C thumb drive has better performance or faster speed.Therefore, the best option for anything except the Macbooks and other devices which lack the universal and standardized USB ports anymore, and ONLY give you a USB-C port, is this thumb drive. For my Macbook I have purchased the Samsung MUF-256DA/AM USB-C thumb drive which has slightly worse performance, sticks out too far, and is flimsier and more prone to damage (it is much easier to hit and bend the drive than this one which is thick and sits almost flush and will not bend when inserted).What would I change about this device? Nothing.The only thing I would change is bringing back the USB-A port on Macbooks so I could use this wonderful drive on my Mac as well as my PC (there are adapters and dongles, which is what Apple loves to sell you these days instead of giving you the Steve Jobs “It Just Works” product). Also, Apple doesn’t want you to buy this product instead of their $200 SSD upgrades. I have two of these and they are fantastic. Surprisingly I have not found them to overheat despite their small size.

Update 7/27/2020:I have continued to use the Samsung Fit USB 3.1 drives as my now “go to” flash drives of choice, I have purchased several of these in various sizes including 32GB, 64GB, 128 and even 256, (and more than 1 of each in most of these sizes). These drives have performed well in my vehicle, my laptop and most importantly my gaming desktop. In fact I have been able to play several older AAA (top rated graphics) games directly from these flash drives without any performance lag and actually performance increase in most cases, but a word of caution they DO GET HOT, like MOST flash media (including SSD drives) so I have found a way to manually “cool” my entire USB hub by using a cheap desktop fan purchased from Amazon! For all the people who say that these drives are cutting off and not being recognized, I restate my point above 1) heat from your usb hub or device “may” be the issue 2) You have to make sure that you have AT LEAST A USB 3.0 port or higher, most newer motherboards and even cars have this and some have USB 3.2 (blazing fast). 3) I have a much older gaming rig that is still amazingly going strong but I have updated it with USB 3.0 ports via a PC Express adapter (sold off Amazon). 4) If you are going to use these for a USB 2.0 port device or lower then just stick with a cheaper flash drive like Transcend or Sandisk that will probably actually perform better on an older (USB 2.0) device, and yes the write speed is about half as fast as the READ speed, I get about 190 MB read, and only about 50 MB write (Crystal Disk Mark), but that still smokes most older Hard Drives. Just my updated opinion!I bought this drive to use with a USB 3.0 port card installed on a older computer and as a supplement to another 32 GB Samsung Fit I was already using to speed up my system (Windows Readyboost). As long as you have USB 3.0 or 3.1 ports on your computer, or an adapter card installed you can get close to 200 Mb/s read speeds, using Crystal Disk Mark I got READ speeds at 189 mb/s and WRITE speeds at 46 Mb/s, (on PEAK Performance Test). mind you these speeds are still faster than my Seagate FireCuda Hybrid SSHD drive and any of my old WD classic hard drives (on my system ), but they wouldn’t be faster than a built in SSD. As far as gaming I’ve been able to run most smaller games (less than 10 GB ) off of this drive no problem, this works well for many of those 2D and mini 3D games that you can find off the Steam Store and other places. However, I’ve tried to run some older AAA Title games like Far Cry off this drive and while it did load much faster than running it off my built in hard drive, it lead to game crashes and system reboots, but the problem could be that my Motherboard is to dated to handle those large data streams coming in from the PCI port ( its not even PCI 3.0 I think Installed USB 3.0 port, not built in). Overall though solid performance so far and with the faster speeds of these “cheap” USB drives as a gamer or maybe even some light video editing, these drives are a good alternative to eating up internal hard drive space! So far very impressed and so much that its convinced me to purchase a Samsung T5 external SSD, I definitely think SSD is the future of storage and with USB 3.1 Gen 2 the speeds are supposed to get ridiculous (side note) but I definitely think that these drives perform better for opening programs and doing gaming, and may be able to breathe life into an older system, providing you have at least USB 3.0, with 2.0 I wouldn’t bother because the read and write speeds wouldn’t show any major improvements.

It’s small but boosts my memory a lot. Great quality and value. Makes me work faster. Sturdy and compatible with my laptop.

Super tiny and fast 256GB flash drive. It may say USB 3.1 but this drive absolutely benefits from using a 3.2 10Gbps port. It gets noticeably higher sustained speeds and just performs much better and more consistently. Great performance for the tiny size! Would not be surprised to learn it has a high performance MicroSD card inside.I purchased this to store ROMs and portable software for my HTPC and softmodded consoles. I can configure stuff on one computer then play it on the other. However with home networking and average internet speeds finally getting faster there is much less need for portable storage like this. Personally I am running out of reasons to use this as I run most things via my home network now. That said it’s dead useful for installing Windows and it’s always handy to have a big and fast flash drive around.
