SanDisk128GB Extreme PRO USB 3.2 Solid State Flash Drive - Up to 420MB/s, Durable Aluminum Metal Casting - SDCZ880-128G-GAM46, Black

Reliable, Fast, and Surprisingly DurableI bought two of these drives in 2023, and both have been working flawlessly ever since. One of them has shown a single reassigned block in CrystalDiskInfo, but it’s been stable like that for over a year—no performance issues at all.These drives are reasonably priced, very fast, and seem to be built with quality in mind. They do run a bit warm, and CrystalDiskInfo sometimes flags them as “overheating,” but I reached out to SanDisk support and they assured me that’s normal for this model.The real surprise? One drive accidentally went through a full washer and dryer cycle. After letting it air dry for a day, it still worked perfectly—and all the data was intact. (It even came out clean!)Highly recommended.

I’ve been using the SanDisk 256GB Extreme PRO USB Flash Drive for a few weeks now, and I’m seriously impressed. The speed is incredible—transferring large files is so fast, and the read/write speeds are consistently smooth, even with large video files and high-resolution images. I’ve used a few other flash drives in the past, but none compare to this one when it comes to performance.The 256GB storage is perfect for storing all my essential files, media, and backups, and I love that I don’t have to worry about running out of space anytime soon. The USB 3.2 compatibility ensures that it works seamlessly with my devices, and I’ve had no issues plugging it into my laptop, desktop, or even my smart TV.The build quality is also top-notch. The aluminum metal casing feels durable and solid, which gives me confidence that it will last for years. It’s also sleek and compact, so it fits easily in my pocket or laptop bag.Overall, this flash drive is an excellent investment for anyone who needs fast, reliable, and high-capacity storage. Whether you’re using it for work, travel, or personal use, I highly recommend the SanDisk Extreme PRO!

Excellent product! One of the best and fastest flash drives I've ever used! File transfer speeds are super fast. I have a few of these drives in different sizes. It's well built, and is compatible with everything I need it for. It's a great size, and it's design allows it to be put on a keychain if you want. It's like any good flash drive, plug and play.

Before buying this, I made the mistake of buying a "too good to be true" cheap 2 TB USB drive. It was slow, unreliable and wasted a lot of my time messing with it. This device was the exact opposite - fast, reliable and no messing around. At my age, I should know that you get what you pay for.This device is 3X more expensive for half the capacity (1 TB). Was it worth it? Absolutely! The cheap device took 30 hours to get my data onto it, only to find out that about 30% of the files were corrupted. This device took 5 hours to copy all my data and it with no corrupted files.What else can I say? It's a great product and I would recommend it to anybody.I have a suggestion for an improvement. Turn the device 90 degrees and have it plug in from the side instead of at the end. It is 3 inches long and I am worried about it getting accidentally bumped or banged and snapping it off or damaging it. If the drive hugged the side of my laptop, the chance of accidentally catching it on something would be drastically reduced. I'll bet the smart engineers at SanDisk can figure out how to do this.I can't wait until the 2TB version of this drive comes out. I'll be first in line!I've read other reviews that talked about being concerned about the drive heating up. I copied data to it for 5 hours straight and it got warm, but not warm enough to ruin the drive or shorten its life.

I've been using it for about 3 to 4 weeks now, and it's performance is not disappointing for me. I'm a software engineer and I backup many customer projects on this device, projects that contain thousands of tiny node.js files, and the speed of backing up 100 megs of PHP 8, with assets such as JavaScript and Node.js files takes 7 minutes now, where before with older technology it took 1 hour and 15 minutes. Restoring the files from this device to my Dell Precision 7865 takes 6 minutes now. Perhaps the AMD Threadripper Pro technology gives that 1 minute edge over my Intel technology at the office.I also have a new Kingston Data Traveler Max 1TB with USB Type C connector, that was given to me last week for evaluation from Kingston to compare against this SanDisk. The Kingston is quicker using the same PHP project, by about 10% to 15% in both directions. It takes about 5.5 minutes to backup the same project, and about 4.5 minutes to restore it.So far I like the packaging of the SanDisk Extreme Pro better now, well until the slider stops sliding and locking into position, so when that day comes I will like the Kingston Data Traveler Max packaging better. The Kingston packaging is simpler and cheaper looking, not so flashy or complex.I like both, this SanDisk and the Kingston, and won't take sides or say one is better than the other. If I had to choose one, I would cheat and get both, and not tell anyone. For some weird reason, I can't let go of the SanDisk and I keep using it, not shifting to the Kingston because it's faster. So that must say something.As far as heat goes, I read some reviews where they said the units were very hot after use. Both the Sandisk and Kingston didn't get hot on me from actual use. There was one time the SanDisk was very warm, but I had left it plugged in the computer while not using it for about 4 hours as I was writing code. I usually eject and unplug after use as habit.Back to the Sandisk ...I haven't had anything with the name SanDisk on it fail on me yet, but I haven't used these really hard yet either, so time will tell. They all seem to have generous warranties even after expiration, so that's not a concern either. I don't work directly off these devices, which I think is a bad idea and no matter what brand it is, it will not be immortal and live forever.

Excellent and so fast — what snail USBs was I using beforehand? lol
