RAID 6 vs. RAID 50

With 8 drives, RAID6 is a fair bit faster...

No, it isn't.

 

 

Assuming I had 8 4TB drives and a compatible RAID card (Which I do not), which configuration would you go with and why? Just curious...

RAID 6. You can lose any two drives with RAID 6. You can lose up to two drives with RAID 50, but it isn't any two drives. You can lose one drive from each striped RAID volume. With that said, you will get much higher write speeds with RAID 50.

Anything built with screws is meant to be disassembled.

With 8 drives, RAID6 is a fair bit faster than RAID50 and also has better fault tolerances.

RAID 6 is freaking expensive though

Why do i always get blue screens? Why not a red one for a change?

*cough* ZFS *cough* :D

You could even leave out the RAID card with that (or at least just use a cheap one).

If you really want to stick to the RAID card setup: What wpirobotbuilder has said.

In order to do a RAID Z setup, I would just need a RAID card of some variety purely for connectivity, right?

No, all you need is a straight SATA connection as in JBOD or a HBA mode, then again you need 8 ports so probably still need a card?

 

If you're even thinking ZFS even FreeNAS read this blog, it will save you future headaches. Its a must read for anyone tinkering with ZFS, learn without hitting the known failure points.

I roll with sigs off so I have no idea what you're advertising.

 

This is NOT the signature you are looking for.

Very interesting article, thanks for the link! :)

A few notes: Many of these issues will not be very relevant if you're just

doing a home server setup (for example, most things related to performance

will most likely be of little importance if you're building a media streaming

machine). It's still very good advice from what I can tell, but just as a

side note.

One thing I would definitely apply to my own rig which I have not done with

my current server is the ECC memory. When ZFS verifies your disk data and you

have a random bit flip in your memory, ZFS will likely think it has found

corrupt data and "correct" what's on your disk. ECC memory should prevent

that.

I can definitely recommend ZFS from the experiences I've made so far, but

I also recommend doing some proper reading up on it and making sure it's

a good fit for your needs before you go ahead and deploy it.

This is fantastic. Adding to the Storage How To.
