Raid 10 for storage+os?

[rustynails87]

whats up guys as u may know i want a computer that i can store a whole bunch of movies music and other stuff on. my question is i am thinking bout getting an adaptec card is it okay to have my os and data partition installed all on raid 10 together?

also if i put in 6hdd, 2tb each how much storage would that give me?

Yes, and around 6 tb.

In this case how many hdd can fail? 2?

It's fine....but it's waste of money. Depending on how many drives you have or plan on total. If you were going 4x drives RAID 10 for the OS and 4x more drives RAID 10 for storage...waste of money, just do 2x drives RAID 1 for OS and 4 or more drives RAID 10 for data.

If you wanted one huge array for 2x partitions...you can do 4x or more drives RAID 10 for 2x partitions...OS and storage.

For a "Server"...esp just for file storage, don't worry about speed of the partition for the OS so much. It's a "server"...it runs 24x7, boots up what...couple of times a year to shove in updates? Of if running *nix like FreeNAS...runs for years and years on end without reboot.

Assuming you're starting with the minimum of 4x drives for RAID 10....it can handle "up to 2" drives failing..providing both aren't mirror drives.

Picture how RAID 10 works...and think about which second drive failure can work..and can't work.
