SanDisk64GB Extreme Go USB 3.2 Type-A Flash Drive - SDCZ810-064G-G46, Metallic Bronze/Gloss Black

After experiencing some Flash Drive issues with the cheap drives I usually use and after doing some research, I discovered that not all USB 3 Flash Drives are alike...not at all. There is a definite relationship between cost and performance for the same capacity, in my case, 64MB. Most of that performance is related to read and write speeds....more money, more, and faster.My Synology Router requires a Flash Drive to offer certain security features, and when initially using an unknown chinese brand USB 3.0 drive, the router would report a data failure and have to rebuild the entire database. This happened about once per day. So I looked on the Synology website and found they recommended specific flash drives, the SanDisk Extreme is one of the few that have been certified to operate well with their router. After installing this 64MB Sandisk Flash Drive, the usually long router process times to manage the database are not much faster, and I have had no issues at all with read or write failures that caused me to find a quality drive in the first place.

This SanDisk Extreme Go USB 3.2 is an excellent flash drive. Super fast speeds make transferring large files a breeze, and it performs consistently without any hiccups.The build quality is sturdy and durable, so it feels reliable for long-term use. Whether for work, backups, or everyday file transfers, this drive gets the job done efficiently. Definitely a solid choice for anyone needing speed and reliability in a compact form!

Excente muy bueno

This thing is fast. I'm seeing sustained reads of 391 MB/s (rated 395) for a 9.4 GB write test consisting of large ISO files and sustained writes of 147 MB/s (with peaks around 172 MB/s--rated 180) for the same test files. The writes are faster than the reads on many cheap USB drives. Something on my Win 11 Pro Laptop was causing a long bog-down at some point between half way to 3/4 through the read test so I needed to finish the test on Liunx which showed the true read performance. It's probably something unique to my laptop.I wish there was some kind of dust cap for the USB end.

Even though it meets or comes really close to the stated 395MB/s & 100MB/s write, is that enough? These drives have terrible random read/write performance. At the $18 price point, it should do better. The Vansuny Green 64GB USB 3.1 Flash Drive - 350MB/s read / 200MB/s write drive is only $13.49 at this time. If you spend the equivalent $ with Vansuny you can get a 128GB black drive with read and write speeds up to 400MB/s and 240MB/s. They're also giving you a $3 off coupon to sweeten the sale. The SanDisk drive does feel like a step up in build quality-wise compared to the Vansuny drives. But it is just that, feels like. That doesn't translate into the lifespan of the drive. I have a few Vansuny drives and have not been let down yet from premature death. Save some money and get yourself a Vansuny drive.

Exactly as described - Heavy Duty

I am returning the SanDisk Extreme GO mainly because of very poor performance when transferring large number of small files. First the build. Nothing special and disappointing when I first received it. The black portion is very light and flimsy feeling plastic. The "metal" portion does not look like bronze, perhaps closer to titanium, but I guess the marketing gurus thought bronze sounded good. Ergonomics are poor or fair at best. Handling the plastic while inserting is not comfortable and if you handle the metal portion while inserting (most natural and comfortable), it has the tendency to collapse and slide closed. That's because they designed it so that you need to press down on the rear half of the metal portion to get it to close. So if you touch or handle the metal portion while inserting, it will tend to close on you. Best way to insert might be to handle it by the side edges of the black plastic. It's a kludgy design.Unfortunately where the Extreme GO falls down the hardest (a fatal fall), is in random read and writes. See attached CrystalDiskMark scores. Look at the random writes; practically non-existant. When I attempted to transfer a large (62GB) folder with mostly small files, the Extreme Go turned into the Extreme SLOW. It was painful to watch and I had to cancel the process because it was evident after a while that it was going nowhere. If you are mainly transferring single or a few files like 1080P or maybe even 4K movies, your experience will be much better. If you have folders with many small files to move, try the more expensive SanDisk Extreme PRO or better yet, the Fanxiang F395 which performs even better for less cost. See my Fanxiang F395 review including benchmark scores that rival the best flash sticks out there.

SanDisk still makes reliable, solid and dependable flash Drives. No problems.
