Some variations of this chipset have compatibility issues with the UAS (USB Attached SCSI) driver in Linux, which can cause slow transfer speeds or connection drops. If you experience extremely slow write speeds on Linux, you may need to apply a quirk to force the device into USB Mass Storage Bulk-Only Transport (BOT) mode rather than UAS.
The VIA VL700 supports (USB Attached SCSI Protocol), which is faster than the older "Bot" (Bulk-Only Transport) mode. However, UASP is notoriously unstable on certain versions of Windows 10 and Linux kernels. usb device id vid 14cd pid 1212 link

Every USB device has a unique "fingerprint" called a (Vendor ID) and a PID (Product ID). According to databases like DeviceHunt and The-SZ , this ID corresponds to: Add a plain-language product name and short description
