Great price, great quality. Working fine.

Perfect size and it works great

Solid portable storage device. Great that it comes with both USB-C and USB-A connectivity, so you can easily switch between modern cell phones and computers if necessary without needing to purchase extra adapters. It isn't the fastest as far as writing data, with about 10% of the read speed for writing it may take you a bit to back up your data. However, you're going to spend a lot more money to get something faster, so it all depends on what your priorities are. Seems solid enough to keep in your pocket without worrying about it much, works well for what it is, and is easy to use. Hard to come up with tons of complaints!

Small and fast

This thing is very fast! I moved over 100 megabytes onto it and done in less than a heartbeat. No really, I timed it. My heartbeat is slower. Nominally? you're going to get a bit less than 512 GB - I didn't ding it for this because industry practice does this with everything. It's closer to 470? give or take. However this is plenty for me, and especially so compact! I love that the case doesn't just seem sturdy too - it looks good doing it. Sleek, professional, and with the lanyard cable this is something I could totally see hanging off the side of my ESD work bag. Except, I loathe losing it in my office and will likely keep it at my home instead. I'm very satisfied with this, especially as my old back-up external is nice but is almost all taken up by well, back-ups! with this I can swap humongous files way easier - ISO, EXE, and datasets too! And I love how portable it is. I can't think of a single issue with it and even price for performance seems reasonable to me.

I was recently on a vacation in the UK, and while over there, I was warned that my Google photo drive was full. And instead of paying them more money to expand that storage, I figured I would just delete the photos in my google drive and then back up my photos from my phone at a later date. Luckily for me, I had this on me, and simply backed up my photos onto this SSD via the USB-C port on my phone. And THANK GOD that I had this, because unbeknownst to me, my phone does not simply back items up to Google, it "syncs" with it. So ALL of the photos that i had deleted to make room on my google drive, were also deleted from my phone at the same time. This was over 2 years worth of photos that I would have lost if not for having been able to back them up to this SSD drive. The drive is small, an easily carried with you in a backpack or purse (it's pocket sized as well, but you'd need to travel with the USB-C cable as well). It works with both Android and iPhones (but you'd need an adapter for lightening port, unless you have a newer iPhone that uses USB-C). Backing up the entirety of my phones pictures and videos only took a few minutes. I would HIGHLY recommend having this product and taking it with you if you don't have a huge Cloud storage service.

Comes pre-formatted as exFAT with 476.91GB addressable and includes a 10gbps USBC cable (one end has a USBA adapter if needed). On 10GB files without buffering (that is, the drive speed rather than the speed with using computer's paging file), I get a 40-50MB/s averaged write speed, and consistent 410MB/s read speed. In other words, you should expect it to take at least 3 hours (likely over 4) to fill the drive as formatted, and a bit under 20 minutes to copy it all somewhere else (assuming destination is at least as fast as this USB drive). Drive cache looks to be 2-4GB; so first 2-4GB will write at ~330MB/s, then ~35MB/s after. With the drive fille 90% full and with 10GB unbuffered write tests again, write speeds declined to 35-40MB/s, while read speeds declined to 380-390 MB/s. Speeds may have been affected here by thermals; despite having a small fan inside, the case got quite hot to the touch in testing. Overall, I would say this is fine for: -Redundant computer/phone backup option (using differential images, not full/fresh images each time) -Ventoy bootloader -Write-once, read-many library (e.g. videos, ebooks, where it's all populated once and then mostly just read from for the rest of its life) -Storing images/video from phone/tablet It would not be good for: -Full/fresh PC backups -Frequently moving videos between computers (e.g. in video production) -Boot drive An NVMe drive in a USB enclosure will be faster if you have a fast USBC port to support it, but it will also be substantially more expensive; for the price ($46 for 512GB version at time of review), I think this is a good product.

This drive behaves just as advertised. The speeds of around ~450MB/s is accurate. I use this drive to store steam games that I want to play on both my laptop and my desktop. I install the games on this drive and play them directly off the drive. I haven't had any issues with loading times or performance.
