But. . . RAID is twice more expansive. (600euros/month for a 5x750Go SATA2 with 12Gb of ram and unnecessary 2x quad core) didn't find any RAID 10 "not too expansive" dedicated server. If this setup is twice as fast, I can afford it. But if it a 30sec VS 40sec...I'm not sure my customer will pay. >> Which OS would you use ?
