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 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. Link to comment Share on other sites More sharing options...
