Blazing fast
By Kevin on Reviewed in the United States on February 16, 2022
By far the fastest 3.0 drive I've owned to date. My solid state OS drive is the only drive that can send files to the flash drive at it's maximum write speed. My mechanical drives all averaged about 140MB/s sending speed, and the flash drive was barely flexing. Many files were in excess of 9GB, but its temperature never concerned me. Feels like a solid (heavy) little drive. I own multiple PNY 2.0 drives, and have never had an issue with them. I went with PNY, because they haven't let me down yet. A Lexar 3.0 drive on the other hand, would write files that when transferred, were corrupted. It's the only drive I've ever seen do that. Capacity is exactly what I was expecting. A true genuine 1TB. Finally! A 3.0 drive that actually WRITES at 3.0 speeds!!! Only con I can think of, is the price dropped $15 shortly after purchase. Now (few hours after review), I'm noticing throttling and heat on another PC. Ambient temp is higher, but I'm leaning toward a port issue.

High capacity, Poor performance
By shieken on Reviewed in the United States on July 20, 2020
I've been using Sandisk USB pro (older version) which gives much better consistency and performance, top read speed sustained at > 190 Mb/s. Not a fan of slide design, and clicking mechanism hasn't been bit glitchy lately. I wanted to get larger drive capacity with same performance, and though to give PNY a try. Unfortunately best part is the high capacity and actual performance did not meet expectations and ended up returning. Initial copy/move of files tend to be fast. Fastest read I got was > 300 MB/s when copying, however this was very rare. Yes I used USB 3 port. Main problem of this drive is the performance. After few seconds of copying, it's speed dramatically drops to USB 2 transfer rate, and the sad part is that it can't even maintain full USB 2 rate. After initial burst of data transfer, It would read/write files at avg 30-50 Mb/s for a 1-2 sec, then it's transfer rate drops to ~10 Mb/s for another 1-2 sec. It fluctuates between these two rates until transfer is finished. Imagine trying to copy 80GB of data like this - I tried multiple times on different computer with different file sizes & types. This makes me think that it has internal buffer for initial data transfer but its capacity or performance is so poor that it cannot maintain it's transfer rate. This PNY 512GB USB 3 drive claimed super speed but cannot match consistent copy/write performance of cheap USB 2 drive I got it for free. When I got the drive, it was formatted as FAT32, which it has file size limitation, not useful for copying large file sizes, which I had to reformat as typical current standard of exFAT for large capacity USB drives. Perhaps it's performance would've been fast as it claimed on FAT32 format, but it would've been useless since I sometimes transfer file seizes > 8GB. If you're using this mainly as STORAGE USB drive, it might work for you, since it has large 512GB capacity. Even then with poor read/write speed, it may not work out. May work as archive USB drive. Actual USB drive felt very solid, I really liked the drive itself, but the poor performance was unacceptable. I rarely return items I buy, and this was returned quickly. If you're TRANSFERRING large amounts of files & data and want it done fast, this one failed. I am considering to get larger capacity sandisk USB pro version.
