dave-the-cat Posted June 7, 2011 Share Posted June 7, 2011 Hi all, Wonder if anyone could advise? Sorry, if I am in the wrong part of the forum I've got a newish MacPro Server with 4 HDs: 3 x 2TB, 1 x 1TB. At the moment the RAID volume is the 3 x 2TB, and the OS sits OUTSIDE on a separate HD. It all backs up onto a Drobo using Time Machine. Is it better to have the OS 'on' the RAID volume, or outside on a separate HD? My worry is being software RAID, if the OS HD dies so does my array, irretrievably. And to be honest I don't know of the Drobo mirror gives a bootable clone. Thanks for any help you can offer – am a newbie to RAID. All the best, Dave Link to comment https://www.insanelymac.com/forum/topic/258645-raid-gurus-os-within-raid-or-on-separate-hd-macpro-os-x-server-10-5/ Share on other sites More sharing options...
3.14r2 Posted June 7, 2011 Share Posted June 7, 2011 RAIDs can be used either: to speed up the system (by increasing read/write speed to/from HDD) to have a reliable backup (read for storing data) for both the above slightly reducing benefits of each A software RAID is not reliable in any case (besides, it can only be read by OS it was created in). The best RAID is a hardware RAID. By hardware RAID I mean a dedicated PCI-E/X RAID card. It is up to you do decide which is more important - data, speed or both. Usually in servers the third option is used. For home user a reliable backup is more important (I do my data backups to RAID volume). If you do video editing, then speed is more important. Anyway, be sure to read this info.
