SanDisk 256GB Extreme PRO USB 3.1 Solid State Flash Drive - SDCZ880-256G-G46, Black

It does make download faster and plays back fast. Use it with my Blink camera. Very happy with its performance. Worth paying the extra for its speed. And Sandisk has always been reliable brand I’ve used in the past as well.

Solid state thumb drive; fast, reliable data transfer. Available in large denominations (up to 1 TB). Great value.

I purchased it to work as a universal usb bootable device to boot various Linux ISOs. Previously, I used a Lexar flash drive for this purpose. It is very temperamental and is often not mountable.The Sandisk extreme pro works fine and doesn't have any of the problems of my previous flash drives. I haven't done a speed test, but it does seem responsive. An interesting quirk is that the blue led remains on all the time, even when you are not reading and writing. It does get warm. Unlike other users on this forum, I have not transferred large GiB files, so I have not experienced the high temperatures other users have reported.I purchased the 128 GB version. It came pre-formatted with a MSDOS label and a single exfat partition. I reformatted it with a GPT label and divided it into several partitions. I am using it as a Linux diagnostic and multibootable flash drive. It works exceptionally well for this use case.

Just got this today (09/26/17). Bought it to make a Multi-boot Flash Drive. YUMI now has the option of creating a Win2Go partitions which work very well and it is very fast with this SanDisk Flash Drive. It only took about 10 minutes to create, which is in-it-self really, really fast. So once I was done with the Windows 10 Pro install, I decided to see just how fast it really is. My system is a very fast computer. Running at 4.7 GHz, it really gets things done quick. I also have twin hardware RAIDS (5 & 10) which are very fast. Normally it boots using a decent but older 250 MB SSD. So booting with this flash drive really surprised me because it was just about as fast as my normal boot up with the SSD drive. As a new install, it would of course be faster then the existing install would be, but the flash drive is running in a USB 3.0 slot as this computer is a few years old and does not have a 3.1 slot at all.Once up and running, using ATTO for benchmarking I benchmarked all 4 of the drives. Remember, these are either hardware RAIDS (2 of them), the SSD Boot Drive and the Flash Drive. I was very surprised with the results rather then talk about which one was the fastest, I did a screen grab of the winner. If you look carefully, you will see it's drive C:, which of course is the Boot Drive on this USB Win2Go install. This Flash Drive has to be a record holder I think.

This USB Drive is blazingly fast and extremely easy to use, just plug and play. It's also impressive how much speed it can put through USB Gen 1, it's almost on par with what I'm replacing it with.However, I am returning this due to the speeds that an M.2 NVMe SSD in an External Enclosure can put out, plus expandability. The left image is this USB Drive, the right image is my "WD_BLACK 250GB SN770 NVMe" paired with a "ORICO M.2 NVMe SSD Enclosure". Almost no difference in the first Read test right? However every other speed is much better, plus this combo cost me $60, and the SSD I used isn't even the fastest. On the review page for the Enclosure, someone reached nearly 1GB/s speeds! I don't pretend to be an expert in storage devices, but I do dabble, and this is the conclusion I've come up with: in terms of Value, I prefer the M.2 Enclosure setup.If you just need a simple USB-A Drive that puts out speeds beating almost all others, this is an easy recommendation. However, if you're like me, and you want the most out of your storage device, maybe invest a couple more dollars into an M.2 Enclosure setup.

Update: After 1 week of use, the only con I can think of is that it does get warm when left plugged in. This occurs regardless of whether or not I'm actively using the drive. It doesn't get "hot", but definitely warmer than any other flash drive I've owned. This may be what has caused some of the failures that other reviewers have mentioned (and some even have mods for). I just won't leave mine plugged in when I'm done using it.Original post: I have one of the older SanDisk Extremes that I've been very pleased with. I typically have to transfer large (1-3 GB) files and the older SanDisk Extreme easily maintained >100MB/s write speeds throughout. It is still going strong but I wanted to have an extra in case it ever fails.I tried a couple other cheaper brands that promised even better write speeds but none came close to the SanDisk. Even the new version of the SanDisk Extreme doesn't keep up with the older one so I paid a few extra bucks for the Extreme Pro and WOW! This thing is way faster. I just transferred 5 files at once, totaling over 10GB, and it never dropped below 300MB/s writing to the flash drive! If this one lasts as long as my original SanDisk Extreme it will be worth every penny.

I was looking for an extremely fast drive, and this definitely fit the bill. The product text doesn't really emphasize this, but this is NOT a flash drive. This is essentially an SSD on a stick. From a BIOS/Driver standpoint, the OS see's this as a USB connected SSD drive, not a flash drive. This gives much more reliable driver operation, and allows for much faster transfer rates than a typical flash drive.ProsSpeeds rival almost everything else I own.Device mounts, connects, and disconnects easier than a typical flash drive, across multiple OS's.Rock solid operation with no delays or errors.ConsStick is a lot longer that usual flash drives, and is actually longer than it appears in the picture.I dislike the pop out USB dongle, which sometimes pops back in while you try and insert it.Doesn't come with a lanyard, which would be nice for the lanyard hole in the product.Overall it's an excellent SSD stick.
