I'm kinda new in this raid thing. As far as I understand raid 0 combines both drives which increases the throughput by splitting up the data. Raid 1 uses the 2 separate drives in order to achieve more security (loss of data) but you'll get lower transfer speeds. So far so good... I bought myself a Thunderbolt 512Gb SSD from Lacie with the idea to connect it to my (ordered) 27" iMac partially as boot drive and the rest for personal workflow (audio engineering). But I also want to make a bootable disk image of my system drive in case something happens, I can quickly put the image back on the drive without the hassle of installing the complete system over again. Now the drive came as raid 0, so 1 volume of 512Gb. But I want to have a small partition (or 1 drive) for the system and apps and there rest (or 2nd drive) for work around. For storage and/or backup I ordered a 3TB HDD in my iMac. When I go to disk utility I cannot partition the drive because it's in raid 0? So my questions are: - What do you recommend as boot disk? raid 0 or raid 1 - When raid 0, is it possible to make a good working bootable disk image of a raid 0 drive? - When raid 1, should I partition or just use 1 complete disk for the system and 1 for documents? - Should I put my system on the internal HDD and use the SSD only for sound banks, samples, workflow What do you think is the best option? Big thanks for sharing your experience!
