Surprisingly fast and feels bulletproof!
I ordered this just to have a Windows To Go rescue disk and it handles that beautifully; runs virtually as fast as my system does when using my SSD. The speed is crazy! Read Gb/s in the mid 300's and WRITE in the high 200's. As others have said, it doesn't slow down on big jobs. It gets warm but not hot. This shows up on my system as a SCSI drive, different than my other USB Flash drives - is there an M.2 drive inside???? This acts more like a pure removable SSD than a USB Flash. Made of metal & feels bulletproof (maybe it IS!). Ordering more (bigger capacity) for sure.

This thing is spectacular.
I got this not sure how fast it would be, because the last flashdrive I got was unreliable and overheated. This one definitely gets warm after use, but it is so blazing fast. I have been using it for months now and have transferred so many files. I am extremely happy with it. The solid metal feel is sturdy and resistant while also protecting your fingers from the heat when you reach for it. It managed to make it through a hectic move across the country and I love the USB-C that comes with it. My Dad only has USB-C ports so it's perfect when he asks me for my videos. It transfers Gigabytes of data in seconds! Don't go for the ultra cheap ones, they don't store as much as advertised, are unreliable, and slow. My Dad lost Gigabytes of data because of this. Get this so you don't waste your time, and start enjoying blazing fast and reliable file transfers!

Top notch super fast and durable after three months
I researched for quite a lengthy while before deciding to get this flash drive because of being burned by a name brand Samsung flash drive that would fail and no longer be recognized on any device. I search and searched, and searched, and read all the possitive and negative reviews on numerous flash drives and decided to give this one a try, and I'm happy after 3 months of using it. This flash drive is super fast both with loading and offloading, and it's build into a durable heavy-duty casing that has held up thus far and still looks like new. Additionally, it comes with a soft case to tuck it into when you're not using it, which is very handy with keeping it identifiable from other things in my bag.

Very Fast Write Speed that Does Not Slow When Nearing Capacity
I was in need of a fast writing, high capacity storage means in the form of a "thumb drive" but without their typical limitations. This miniature solid-state drive (SSD) was just what I needed. Writing speed with both small (in the 10-15kb range) and larger (a few to tens of mb) is very fast compared to the best and fasted flash drives I could find. Importantly it does not begin to slow after reaching about 50% capacity and reach a crawl at around 90%. The body and cover are metal (likely aluminum). It is therefore very sturdy and when covered seems immune to damage from careless handling, being carried in a pocket, etc. Be aware that this drive identifies as local (internal). This is [probably] done so that it can be easily used as a boot drive. Because of this, I had to make some odd and rather difficult adjustments to my custom programming that uses this drive as, by intentional design, it disallows certain operations to any internal drive. The device gets somewhat warm when simply connected (no reading/writing for hours) and quite warm during heavy write activity. The true purpose of the robust metal casing is likely that of heat sink. It seems effective as the temperature never approached what I consider "hot" for an electronic device. I have no way to assess the long-term durability and no experience with similar devices for comparison. Given the low price and essentially unknown Chinese manufacturer there are likely better choices for applications that find frequent heavy use.

P h e n o m e n a l & unmatched quality!
Anyone need a true SS 2TB stick, this it is! Tested on torrenting applications...just like you who are reading this is planning to use. Don't deny it ;) Positives Very fast, registers as a 3.2usb device. The speeds are blazing (untested) from a user experience only. Great heat distribution, this stick as you can imagine can get hot. The case around it is made of steel. It's created to cool down upon high file transfers. No other USB stick I found uses the entire stick as a heatsink to keep itself cool. My only complaint is not paying for copper instead of steal. Some users have reported that this can be modified in the future (outside warranty). *** I have confirmed this is a TRUE 2TB. Does NOT recycle data. Neutral It's a beast when it comes to durability and ruggness. It's a tough monster that is heavy. If your looking for something light for keychain, look elsewhere. Yes keep any magnetics away from this too. Negatives Hmm, no other color options? Copper would be a better more costly metal. I don't think encryption hardware/software is included (use your own).

It’s compact, super-fast, and versatile, making it perfect for managing my files across different devices with ease. Pros: Incredible Speed: The transfer speed on this drive is outstanding. With up to 550MB/s, large files move over in seconds, which has saved me so much time. It’s significantly faster than any standard USB drive I’ve used before, making it ideal for transferring high-resolution photos, videos, and other large files. Compact and Portable Design: It’s small enough to slip into my pocket or attach to a keychain, which is great for portability. Despite its compact size, the build feels solid, and I don’t worry about it getting damaged with daily use. USB-C Adapter for Versatility: The included USB-C adapter has been incredibly useful. I can easily switch between my laptop, tablet, and smartphone without any hassle. It’s perfect for managing files across multiple devices, whether I’m working from my MacBook or accessing files on my phone on the go.

Perfect for Backup and Media Storage: With 128GB of space, I use it to back up important documents, store photos, and even carry a few movies and media files for offline access. It’s been extremely reliable for all my storage needs. Cons: The only minor downside is that it can get a little warm during long file transfers, but it hasn’t impacted performance or speed. Overall: If you’re looking for a reliable, high-speed USB SSD flash drive, the SSK 128GB model is an excellent choice. Its speed, compact design, and included USB-C adapter make it incredibly versatile, and it’s been a perfect solution for my storage needs across different devices.

Funciona muy bien, irreal que en ese tamaño le quepan los 2TB y la capacidad es real, ya le metí 1.4 terabites y sin problema, es rápido, solo que depende que tu computadora tenga los puertos nuevos y más rápidos para que funcione al 100%, en mi caso transfirió bastante bien 300 gigas a una tasa de 150mb/s pero mi compu ya es vieja, después de los 300 gigas si mermó mucho la velocidad por que se calienta bastante, pero funciona muy bien. Es muy robusto, se siente pesado pero no es grande. Excelente precio lo compré en $2100 pesos, y está excelente. Trae su adaptador a usb tipo c incluido.

This is by far the quickest read and write speeds I have ever seen of any USB i have bought to date. I was getting approximately 350 MB/s write speed which is insane. Other USB sticks don't make 60.

Great, solid and fast! Cover lid limits its access to some tight usb ports as it sticks out at 90 degree.
