My Favorite Flash Drive, Fast, Durable, and Extremely Versatile
This is honestly my favorite flash drive I have ever owned. The solid metal body feels exceptionally durable and premium, and the dual USB-A and USB-C connectors make it incredibly versatile. It works perfectly across all my laptops and devices without needing adapters, which is enormously convenient. Performance has been excellent. Transfer speeds are fast, the 128GB capacity is generous, and the drive feels far more substantial and reliable than typical plastic thumb drives. This is one of those products that quickly becomes part of your everyday carry because it is simply so useful. If you need a fast, high-capacity flash drive that works with both modern USB-C devices and older USB-A systems, this is an outstanding choice and offers excellent value for the money. Compatible with Windows, Linux and Mac

Compact, Portable, Flexible, and FAST!!
Amazing piece of hardware. compact,flexible, FAST!! Was going to buy another one, but the price jumped so much! Original purchase was May 2025 @ $37.00. today it's $60! wowzers!! Think I'll wait for Prime Day or something. Too much when the competition now is around $40-50. But, seriously, if you're looking for a reliable and FAST thumb drive, your search has ended. Get this!!

This review is for the SSK 128GB version
First impression is that it looks great and has a smooth and solid feel that feels great in your hand. The case is a nice touch if you do not want to add a lanyard to the drive itself, which you can do on the USBC side. It is a great value dual flash drive if you plan to handle gigabyte-size files. You can find faster dual drives (at a higher price) like the SanDisk Extreme Pro Dual drive (min. 256 GB capacity), but for most users, this drive will provide reasonable speeds from both USBA and USBC ports. During my own test, downloading a 10.7 GB folder from my HP Omni-book 15 laptop took between 60 and 63 seconds using 10 Gbps USBA and USBC ports. Average write speeds were around 250 MB/s during the first 45 seconds with a peak of 300 MB/s, slowing down towards the end of the download to about 133 MB/s. Average write speed about 178 MB/s. The drive does not get hot at all. All in all, I'm very pleased with this flash drive, the only issue that I have is how hard it is to plug and unplug from my laptop ports. Soon, I will be adding a cheap usb hub to reduce wear on my laptop ports. Note: Previously, I tried a 128GB PNY DUO LINK USB 3.2 that was terrible. It would take over and hour to download the same 10.7 GB folder using the same ports on my laptop.

Game changing
I haven’t tried many dual USB flash drives, but I love this one. It has made life so much easier. It does get warm though like other reviewers have reported, but it’s very fast, very convenient, and a total game changer.

Best flash drive I have owned to date.
I’ve owned a few portable flash drives and this one is the best one yet. Ease of use and I don’t have to use of my laptop space. With a separately purchased adapter: I use it on my iPhone to prevent use up my storage and it save documents while working on my phone and to also transfer data from the phone to the drive and to use data from the drive while working on my iPhone. The keychain storage compartment helps me keep track of it and to protect it from damage because I have broken many flash drives that did not come with a protective cover.

Awesome
I’m extremely happy with this computer drive! It was very easy to install, and my computer recognized it immediately with no issues. The speed is impressive—everything loads faster, and file transfers are quick and smooth. I’ve been using it daily, and it has been completely reliable with no lag or errors. The build quality feels solid, and it’s definitely a great value for the price. Whether you’re upgrading your system or just need extra storage, this drive does exactly what it promises. Highly recommend—would absolutely purchase again!

Performance is great but build quality needs a revision especially for this price
I bought this because I needed a durable and fast solution to keep on my keys, I've bought numerous sandisk,pny, and other brand USB drives, in terms of performance this flash drive more than meets my expectations, its extremely fast which is what I was looking for, however I was also looking for durable and for it to stay on my keys, but after a month of use the holding case has become so loose any time I take my keys out of my pocket the drive just flys out and hits the floor, one time I realized I lost it in a parking lot because of this issue which is a massive deal breaker for me. In terms of value its okay the current prices are awful but it is what it is, its pretty small but in terms of portability the over all build quality killed it.

Tasarımı çok iyi ve kaliteli bir ürün tavsiye ederim.
Ürün çok hoş ve kaliteli duruyor veri aktarırken aşırı ısınmalar oluyor eliniz yanacak derecede, hızı iyi dışı alüminyum sanırım bu sebeple ısıyı dağıttığı için bir süre sonra oda sıcaklığına geliyor hoş bir ağırlığa sahip hissiyatı çok güzel yanında koruma kılıfı var anahtarlığa takılabiliyor. Üründen memnunum ve tavsiye ederim her hangi bir sorun yaşamadım ısınma sorunu olması bana normal geliyor gövdesi alüminyum metal ısınmayı dağıtıp kolay soğuma olacaktır. Teslim tarihinden önce geldi bunuda not düşeyim.

Una de las mejores que he tenido
He usado esta memoria por un par de meses y las velocidades son reales. No se calienta y me encanta que tenga dos entradas usb A y C para mayor versatilidad. También me gusta que viniera con su propio estuche pequeño para transporte más fácil.
