With S-ATA and the hotplug support was added, so replacing a hard drive on the fly. This is often used in NAS devices or servers.
The S- ATA technology is really used only with the use of SSD hard drives, so it is normal for S- ATA hard drives no hurdle regarding transfer rates dar. Furthermore, there is by the possibility of an eSATA SATA port for external hard drives or other devices to use. This is due to its power, in direct competition with USB and can be obtained by slot brackets (often included with a motherboard included) is easily retrofitted.
For small appliances are also more standards in development or already on the market. Here, however, particular caution, as these are not necessarily compatible with each other, such as mSATA micro SATA and. Within the S- ATA standard disks and controllers of different versions can be operated together. It is also possible to operate S- ATA hard drives on SAS controllers (but not vice versa). For IDE devices, there are numerous adapters that allow operation on a S-ATA controller, for example if you wants to take his hard drive in a new system.
