Hi, Not sure if this is in the right place but here goes : I have just aquired a Lenovo TS140 server with the following spec : Quad core Intel Xeon E3 v3 E3-1226V3 - 3.3 GHz 16Gb DDR3 128gb SSD Samsung EVO 850 1.5tb HDD & 500gb HDD It's sole use will be as a Plex Server and it will be running Windows 10. Plex clients include 2 Amazon Fire TV's and some mobile devices. All streams are 1080p and may or may not neet transcoding. Max 2 simultaneous streams but usually just 1. So... I want to equip this with 3 3.5" spinners to store movies (the SSD will be opsys only). My options are to install the HDD's inside the TS140 itself OR to use an enclosure I have and connect it via either USB-3 or eSata - The enclosure is the Raidsonic Icy Box IB-3640SU3 (link here : http://www.raidsonic.de/en/standards/searchresults.php?we_objectID=480 ) My question is, is it best to use the HDD's in the external box or to put them inside the TS140? Will I gain any extra real world performance (considering the useage) by having them as internal drives ? Any advice would be appreciated.
