512GB USB 3.1 Flash Drive - Optimal Read speeds up to 400 MB/s, Write speeds up to 200 MB/s (AK58512G)

Best flash drives I've ever had! I bought 2 of these several years ago, and to this day I have never had a single problem. The cap on it is amazing, and it fits on the end so you won't lose it. File transfers are fast, compatible with every device I've ever tried, and they are easy to carry around. They're a bit pricey perhaps, but 100% worth it based on the quality and durability. I don't really leave reviews, however this product deserves it.

VERY VERY GOOD RESULTS!

PS5 REVIEW!! We ordered this to use as extended storage for the PS5 since the m.2 port on the PS5 doesn’t work yet in the firmware. We had failed with a few other drives because the PS5 requires the drive used for external to be a min speed and many drives just did not cut it. This drive was easy to setup for this purpose and so far has worked great copying many of my larger games over to the drive successfully. For now, all I can say is that it works and the PS5 seems to accept it. The next test over the coming weeks will be to see how the games run on it and if there are any performance issues. We will update this review with those results once we have them.

It's one of the best products with proposed a r/w speed.While many other seller companies specify and a max theoretical speed, this one indicates the stated speed that's important for write activity first of all. Obviously, it's about seq r/w speed and these speed values are stable (not goes down after several GBs copied like others).Also, this flash driver has a small part ~230-250MB in the beginning, so if you formatted and made 1 volume you will and a fall of speed at first ~230-250MB.Anyway, among other 3.1 flash drives, this one is highly recommended

I purchased three different flash drives and have a good comparison between them. The Arcanite drive is the best value for the storage space and form factor, but comes up short on speeds.Pros:Speed- Yes this is a fast drive...for reads. I was able to hit 250mbps easily and up to 300mbps at times. More about write speeds later.Form Factor- I like the sturdy feeling casing and design of this drive. It's nice that the cap snaps back onto the case while in useStorage- Great value for the amount of storage space you get.Cons:Speed- Write speeds would start out decent, around 150-200mbps for around 10 seconds. After that the drive would slow quickly to 50-70mbps for the duration of the write. I believe they have some form of high speed caching for the first few hundred Mb and then it can only write at the standard module speed.Formatting- Came formatted in FAT32, which is outdated and limits files to 4Gb, be prepared to reformat into a better filesystem.Overall this 128Gb drive was a good value and will suit someone who needs quick reads and higher than average writes. If you plan do to a lot of single writes and reads, like transferring some files for work or school, then you may be better off spending more money on a Sandisk Extreme go, which has writes almost three time as a fast, even though the reads are about 30% slower. Also, don't buy any drive with less than 128Gb as files are so large nowadays.*My review based on 128Gb model, which may have slightly slower reads than the large devices.

For the price it's a good deal. I don't need speed, just need it to work. I wanted to have something for larger transfers and this fit the bill.

Please see update to the original review below. It died and warranty appears to only be lines of text on the box... :(This drive is very fast in Windows 10. But, the reason for purchase was to use it as removable storage on my Pi 4. On the Pi the stick is not seen as a SuperSpeed device and the performance reflects that. The Pi is running the latest Debian 10 OS, latest kernal build and latest eeprom firmware. The Pi does work at SuperSpeed with my SanDisk USB 3.1 Fit thumbdrive.Updated! This drive died with 15 days of warranty left. I filed a claim at the link provided by Amazon 1 week ago today. The manufacturer has chosen to ignore the claim and has not even responded to the form. The drive went into a locked state, cannot be read, formatted or otherwise changed. This drive had maybe 10 hours of use in 2 years, photos were stored on it and it was placed back into my safe. Thankfully this is my offline backup only.
