This micro-SD chip board disguised as 2.5 inch SATA SSD appeared on China market about 8 years ago. In the latest version, there were 16 micro-SD slots on the board. The SSD can work under the raid 0 mode. If all slots are fully installed with micro-SD, their speed was comparable to the Toshiba Q200EX.😂 Wish Japanese friends will not be fooled. Don't buy these cheap portable SSDs. Don't buy the self-assembled portable SSD either.🧐
