Hi, For some time I have been using SoftRAID's (http://www.softraid.com/) drivers (v. 4.0.7) for an OS+apps SSD and my users' accounts on a 2*2TB RAID0 (WD Caviar Blacks) volume. At present the User volume is about 50% full (2 of 4TB). I am considering to make the users' accounts volume a 2*3TB RAID1 (Hitachis) for safety reasons. My questions to the knowledgable people in this forum are: 1) I am aware that a RAID1 will be slower than a RAID0 volume. But will an Apple DU RAID1 or a SoftRAID RAID1 volume likely be faster? 2) Using SoftRAID's drivers on disks/volumes prohibits use of some troubleshooting utilities such as iPartition, DriveGenius, etc. Hence, is it adviseable to put SoftRAID drivers also on non-RAID volumes, such as my SSD boot volume? I am hoping somebody with experience in these things can advise. Thanks.
