How to raid hdd

kunthakenthe · Sep 14, 2014

First of all what is a nas server been wondering for a while. Second of all i have a 80gb(may not go in though but still), 320gb(will go in) and a 1tb i will buy soon(christmas/black friday time). Im wondering how to raid them and if they will even raid. Drawbacks/ Postives please tell me i know that if one fails then all fails but i have about 100gb of storage in the cloud and will include a 256gb ssd(probably wont use all this storage but hey also would a 250gb ssd for the speed be best then get a 1tb later or 1tb first then ssd later i have been on hdd for years.) thanks best answer for help given.

No, you do not want to build aa array with these drives, for several reasons. If you dont know why, you need to do much research, you are not ready to even think about building a raid array.

Do your research. http://en.wikipedia.org/wiki/Standard_RAID_levels

RAID 0 (striped) + 80Gb + 320GB + 1TB = 240GB RAID 0 array, that is soon to fail. 3x the smallest drive
RAID 1 (mirrored) + 80Gb + 320GB + 1TB = 80GB RAID 1 array that is soon to fail. Equal to the smallest drive

thanks so two 1tb how would that do.

"In order for RAID 0 to work effectively for boosting the performance of the system, you need to try and have matched drives. Each drive should have the same exact storage capacity and performances traits. If they do not, then the capacity will be limited to a multiple of the smallest of the drives and performance to the slowest of the drives as it must wait for all the stripes to be written before moving to the next set."

kunthakenthe :

Which RAID level and why?

RAID 0 (striped) - speed. Better met with getting an SSD
RAID 1 (mirrored) - redundancy. Better met with other backup options.

Generally, there are two words associated with consumer level RAID:
Don't bother.
