hi,
On a server I have several arrays, software raid 1.
For this I'm using special raid edition hdd (wd re2, re3). Everything is working fine ( >300 days).

Now I'm going to upgrade one array (2 320gb hdd) to 1T and I'm asking myself if I really need to buy those expensive hdd (100% more expensive) ?

does software raid can work as good as using regular hdd instead of re2/re3 series ???

My concern is : data safety > stability > price.

Thanks
