For private projects, you can search small 1U servers with up to 4 3.5" disk slots and some e3-1230 v3/4/5 cpu. They can be bought for 250-350€ (used) and then you just plug in a disk. They are also good for SATA SSDs and work quite well. You can mix both drives in the same system as well. -- Martin Verges Managing director Mobile: +49 174 9335695 E-Mail: martin.verges@xxxxxxxx Chat: https://t.me/MartinVerges croit GmbH, Freseniusstr. 31h, 81247 Munich CEO: Martin Verges - VAT-ID: DE310638492 Com. register: Amtsgericht Munich HRB 231263 Web: https://croit.io YouTube: https://goo.gl/PGE1Bx Am Fr., 2.
