RAID 1+0 with 4TB green drives, bad idea?
i know that they are not rated for RAID, but this is for only for media and other computers backup. that really will some action but less than 100 hours a week.
My plan is to buy 5 new WD green drives of higher capcity every couple years, to refresh the array, and sell "last generation" 5 drives. the 5th drive is to replace a failed drive.
would this be safe practice? 10K drives arent in the budget, so would 3 out 5 green drives survive moderate use for RAID for 2 years = )
BQ: raid0 two WD green would give you 128MB of HDD cache, how on earth could one user possibly use that much from two "slow as5" hard drives.

Hello there,
I strongly recommend that you don't use WD Green drives for a RAID array. They aren't designed to be used in RAID arrays. When a data error is detected the HDD will try to recover the data and repair the error. However when the drive isn't optimized for use in RAID arrays this might take longer than the RAID controller allows and will result with the HDD being dropped out of the array and the array being marked as degraded.
Consider using WD Red drives instead – they have their firmware optimized for RAID and NAS and have a longer warranty of 3 years compared with 2 years for the WD Green drives. Hope that helps.
