After installing an Ubuntu system on an old P4 system grew the old PC wing. As fast as I've never seen it before. The problems began when the SSD should be used with a Gigabyte X79-UD5 to a SATA 3 port. The SSD came with firmware version 0009, and immediately got the freshly published 0309th From a stable system could now be no more talk - it froze after a few hours running time ever again. After much troubleshooting, when the PC was virtually unusable for weeks, I found a forum post, exactly the described my problem and a firmware update to version recommended 000F. Apparently it is now running at last. I've already had so some hardware in hand, but so sloppy firmware at a not so cheap SSD I had not. If she runs, top, but my confidence is shaken now.
