I attended an event recently when someone locked eyes with me as I entered the room. "Jonathan!" he shouted with excitement. "Do you remember me?" I did not have the heart to tell him I had no idea who he was, but clearly, he knew my name, so we must have met somewhere. "Wow, it has been a while!" I replied, trying to match his excitement. "How have you been? Have you met anyone here? Let me introduce you to some friends!" Introducing someone to another crowd is a pretty standard trick in situations like these, because they will have to say their name at some point, so at least it gives me a hint as to who they are. Eventually, I figured out who he was; it was someone I met from a totally different group back in 2021. Later that evening, another guy came up to me and started chatting me up. Once again, I had no idea who he was, but clearly he knew me from something. I did not figure out who he was until hours later, and shockingly, I have also not seen him since 2021. Did I just time travel that people from four years ago started showing up in my life again in 2025? What is next, USB flash drives making a comeback? Actually, maybe we do. Fresh here at APH Networks is the Netac US9 512GB, but it is not something that time traveled from 2005. It is equipped with USB Type-A and USB Type-C ports, and promises up to 1000MB/s throughput, more akin to portable USB SSDs. Will it deliver as promised? Read on to find out!
Our review unit of the Netac US9 512GB arrived in a small brown corrugated cardboard box alongside the ZX20L 512GB from Shaoguan, Guangdong, China. I have never heard of this city until now, but a quick Google Maps search showed it is located about 300km north of Shenzhen. Everything arrived in excellent condition to us here in Calgary, Alberta, Canada for our review today using the FedEx International Priority service.
The US9 512GB's compact retail box is based off the same template Netac uses for all their products. so you can see the retail package's family resemblance. As you can see in our photo above, the predominantly black, white, and blue design is complemented by areas of shiny finishes, particularly a stylized "t" from the brand itself. A photo of the US9 USB drive is shown in three-quarter view. At the top, you will find Netac's logo. model name, and product description. There is also a badge signifying it can pull up to 1000MB/s. The drive's capacity is printed on a sticker at the bottom right corner. System requirements and product highlights can be found at the back of the box.
