Learn from our suffering people
It turned out fine for me,I was lucky.
But guys who love their data and collections (not pr0n but the real stuff like holiday pics,games,fun,studies,work) should be careful about this.
I switched to WD 1 year back and it's been great till now
^^it takes days(that's right) to rebuild an array with 2tb hard disks while system is running with OS on it on some raid controllers.fastest way to rebuild an array is through bios but that would mean downtime so from an average user's viewpoint raid is not of much use not to mention raid setup is very sensitive to hdd behaviour.the initial WD green series failure in raid setup is well known & even now WD & users alike agree that WD Green is not suitable for raid & costlier Red series is recommended for raid setup.same is the case with seagate consumer drives which have a higher fail ratio in raid setups.outside of servers raid is pretty useless & one would be better off simply copy pasting or using some syncing software to backup data to other hard disks(internal & external).
