Minix Neo Storage is a USB-C hub with built-in and non-removable SSD storage. There are two storage capacities available, 120GB and 240GB.
Two colors are available, Silver and Space Grey, but Amconics is only carrying the Silver color. Both colors come with a carry pouch as well.
I have the MINIX Neo S1 with me. The only difference between the S1 and S2 is the storage capacity. For just S$30 more, you will get twice the capacity, and hence this makes the Neo S2 a better buy as it is more value for money.
In terms of specifications, the SSD is an M.2 SATA drive. There is an HDMI port that outputs 4K at 30 Hz, two USB 3.0 ports, and a USB-C port for Power Delivery (PD). It measures 115 x 44 x 11 mm and weighs 64 g.
On paper, Neo S1 supports up to 350 MB/s read and write speed while the S2 supports up to 400MB/s. During my testing of the Neo S1, it exceeds the speed specifications. I managed to get up to 402 MB/s for write and 414 MB/s for read.
