Question guys: I am a professional photographer with ~8Tbs of files at the moment. I currently use 2 Thecus N5200Pros in Raid 5 array. Each one has 5Tbs of drives in it. I am waiting on the new mac pro and possibly raid card, but please advise.. I tried writing/accessing the RAID5 Thecus on a daily level (Cat6 speed Gigabit) and its TOO slow for huge 40megapixel files. Instead I did a small 2TB firewire 800 enclosure as local (working) storage in Raid 0. Its really nice and zippy fast and each night it slowly backsup the day of work to my Raid5 redundant array. Each day around 8pm i worried that if something fails... Im going to loose all my clients files that day.. really bad. I would love to use a good fast Raid5 array as my working-local storage, for the safety, etc... but its too slow on the Thecus over gigabit. Really.. FW800 is much better here. I know the XRAID over fiber channel would get me up to speed but the difference is $2000vs$10000. More people that need fast I/O for local storage, what do you recommend?? Raid 0 a bunch of drives together and backup each night to the RAID5... or get the new mac pro with raid card and use Raid 5 internally... I think the fastest option there would be the JBOD style over SATA internal P p.s. Any recommendations for the scratch disk.. Ok to use all Hitachi 1TB 7200 rpm drives in there?
