Performance Result
Hot-swapping is supported. Yes, no need to shutdown PC system in order to install it. And it is plug and play supported as well. Microsoft Windows 10 automatically installed ASMedia USB 3.1 eXtensible Host Controller Driver for me. No manual work is needed and I can start using it straight away. For your information, it is using ASMedia ASM1142 chipset and supports Windows XP, Vista, 7, 8, 8.1, 10, Mac OS and Linux. Furthermore, it has SATA 15PIN power port to provide strong and stable power to all connected devices after plugging the power cord of PSU.

Yes, ASMedia ASM1142 performs better than my motherboard Intel X99 chipset USB 3.0 controller. I am surprised that it still manage to push 480GB Kingston SSDNow UV400 SSD with ORICO 2569S3 HDD Enclosure performance. It gets higher 439 MB/s read (417 MB/s previously) and 419 MB/s write (412 MB/s previously) in CrystalDiskMark sequential Q32T1 test. Much better reading speed in 4K Q32T1 test as well. Well done, ORICO…
