I have been using SATA hotplug for years, and it works reliably. However, the OS disk can not be swapped, and I have not tested it with RAID components. I use it to connect backup or extra data disks, usually with a single big XFS partition on them, sometimes encrypted with LUKS. It doesn't work on all firmware: for instance on the desktop computer I'm using now, there are two SATA connectors that can't hotswap. https://en.wikipedia.org/wiki/Serial_ATA «The Serial ATA Spec includes logic for SATA device hotplugging. Devices and motherboards that meet the interoperability specification are capable of hot plugging. Unlike PATA, both SATA and eSATA support hot swapping by design. However, this feature requires proper support at the host, device (drive), and operating-system levels. In general, all SATA devices (drives) support hot swapping (due to the requirements on the device-side), also most SATA host adapters support this command.[1]» -- Cheers / Saludos, Carlos E. R.
