I don't knock the benefits of RAID 0, Dave, just the data security. I would go for 0+1 myself, especially with the price of drives these days.

[davej99]

0+1 ?

[Sebby]

It's a striped set (RAID 0) in a mirrored set set (RAID 1). So, you get the performance benefits of a striped set with the security of a mirrored set.

[Rik]

Or the best of all worlds.

[Sebby]

My case can't fit 4 HDs anyway, so I couldn't do it.

[Rik]

Time for a new case then, Seb.

[Sebby]

Time for a Mac.

[Rik]

Or that.

Thanks for the comments on RAID 0+1, which is new to me. You are right drives are cheap.

I wonder though if it is better to have RAID 0, on my laptop, and RAID 1 on my NAS, providing a high performance working drive and completely separate backup/storage/server hardware. The thing I like about RAID 1 is the ability to remove and secure a single drive for physical backup and slot in another. Also wonder if it is better to split four drives between two systems. The notion is that you need to lose two systems as opposes to one. Not sure how you recover using just the discs in RAID 0+1, as opposed to slotting a drive in a caddy.

There may be laptops using RAID, Dave, but I've not come across one. Most use just a single drive. In theory, with 0+1, if you get a failure, you replace the failed drive and the system rebuilds it. I've never had to put that to the test though.

Rik, the laptop I am looking at from D*** has a dual RAID 0 drive to match the T9500 processor and I think that will become more popular until solid state becomes affordable. Lets face it we are all still using glorified Winchesters.

Now that is real wit.

Now you've got me thinking about RAID 0+1, Rik. I only have 2 x 250GB hard drives, and they must be cheap as chips now. It's a shame a physically can't fit them in my case...

[Rik]

Could you 'sling' them anywhere in the case?

[Sebby]

Nope, it's seriously tight...

[Rik]

Bigger case, then. You can always use it as a Linux server when you go Mac...

[Glenn]

Put them in an external case?

[Sebby]

Don't really want a bigger case - I built a SFF computer for that reason.

I could put them in an external enclosure, but it's a bit of a messy solution to me.

I do the exact opposite, go for a big box with plenty of room for expansion. I have four HDs fitted, but could add another couple if needed.

[Glenn]

This from Mashie (I used to work with him) would suit you http://www.mashie.org/casemods/udat1.html

[Rik]

Neat.

Space is a bit tight where the computer is sitting, which is why I wanted a SFF.

[Rik]

When we moved here, I just took over the second largest bedroom for the computers, then put a bench right down one side.

[Sebby]

That's the way to do it.

[Rik]

When we come to sell, people might find it a bit off putting.
