Hi, I am buying a new Dell T-7500 workstation. After a Hard Disk crash once, I learned that I need an extra hard disk always ready in case one fails. Dell is offering either software based Raid -1 OR Hardware based Raid-5 using PERC6/i SAS/SATA Hardware RAID Card with either 3 OR 4 Hard disks. Specs of system are : CPU : Intel Xeon E 5645 at 2.4 Ghz 8 GB ECC DDR3 1333 MHz RAM 500 GB SATA 7200 RPM HDDs with either Raid-1 or Raid-5 Windows - 7 Ultimate 64 bit Currently I clone my HDD using Acronis True Image Home so that I always have an extra HDD ready but it is not in real time so I will still lose some data. Even if I get a Raid system I still would like to continue cloning the HDD & keep them in remote locations. My main goal is always having a cloned drive Ready. My concerns are as follows & need advice. (1) I am not much of a technical person so if anything goes wrong like a Hard disk failure, how difficult would it be to replace the failed HDD & Rebuild the array ? (2) Would I still be able to clone a HDD as I am currently doing using Acronis software ? (3) Should I get Hardware based Raid or software based & whether Raid-1 OR Raid – 5 & how many HDDs should I get ( 3 or 4 ) if I get Raid-5 ? (4) I frequently Fresh Install Windows-7 in Primary Partition & I have 6 partitions. I just format the Primary Partition & Install OS. It is very easy to do now. But will it still remain same with Raid-1 OR Raid-5 ? Thank You.
