I don't mean to highjack the thread, maybe someone can just give a quick explanation. But if so many of you do not recommend RAID5, what would you recommend instead?
Reason I'm asking is that I also have a RAID5 with 3TB and 4TB drives. Had a RAID5 for years with always the biggest drives and never had problems with rebuilds.
Good question I asked too.
Read this thread where I ask about RAID5 but a lot more about RAID is talked about:http://www.neowin.ne...tion-of-course/
Ill basically sum it up while Im changing from a large drive RAID5: Basically, on your RAID5, there can be a huge ammount of data. This can range from a lot of stuff but, generally in a home, all of that stuff is user replacable. Things that are not useable replaceable are, for example, documents, personal pictures....and thats about it.
Your legal movie, music, etc. rips are are replacable. So why have redundancy on that? The only reason is mine reason: Pure laziness
Popping a drive out and putting another one in and, in Apple terms, "it all works" is a lazy mans drive. There are several drawbacks
Because of the RAID5 write hole and non battery RAID controllers, you could find yourself in a nasty way if your data is missing its parity bit when it tries to rebuild. Another downfall is if your RAID controller breaks or you move the drives to another system: You would have to find another exact controller or another same chipset.
This is why is better in 2014 to make Storage Pools (WS2012 term, its called several ways). Using software you can make a RAID5 but you can also make semi RAID5: Want to never lose that porn video? Keep a copy on all 4 drives.......while to the OS and the end user, you just see one file. A old song you downloaded for your grandma? Keep it only on one drive or at best a copy on two.
Lets you really customize and best of all: Should you format, just reinstall and enable the pool again.
Read the thread. People in there explain it WAY better.
