RAID 1+0 or RAID 10?

I'm not sure about RAID 10, but I think Raid 1+0 should be sufficient for everyday needs. Which HDDs were you thinking of using?
RAID 10 is the same as 1+0, but anyways, I was thinking of getting 4 of these:

They have a 5 yr warranty on them which is one of the main reasons I wanna go with them. And I don't need much more space than 1Tb if that's how much i'd get.
It's a min of 4 HDD's to do RAID 1+0 am I right? And with 4 500GB HDD's in RAID 1+0 I'd end up with 1Tb with much better performance? Correct me if I'm wrong.

You're correct, it is actually pronounced RAID 10 but it is 1+0. I believe two drives act as RAID1 and two as RAID0 hence the speed increase. I have never personally experienced it for myself although I have heard good things about it!
raid 0 = Striping
data is striped accross multiple disks though if one disk goes you lose all data
raid 1 = Mirroring
data is cloned onto the other disk two sets of data gives redundency
raid 5 = Striping with parity
data is striped accross multiple disks with parity though you need 3 or more disks
heres some Info

Raid 1+0 indeed is the same as raid 10. However, if you want speed and redundancy I'd take a look at RAID 5 and its performance:
While the performance of RAID0 with the same amount of drives is:
Keep in mind that these benchmarks were done with a mid end server class RAID card and eight harddisks.
So depending on how large your average file is the RAID5 is quite on par with the RAID10. The main advantage of RAID5 is the fact you only lose the capacity of one drive, so you have 3TB of storage capacity while you can still lose one drive without losing your data. You will have to rebuild the RAID array before you can use it again.
I'd say purchase the 4 drives and do some benchmarks yourself, see which is fastest and if the tradeoff is worth the 1TB storage capacity. And post the results up here ofc

Hmm yeah I guess I should try RAID5 then. I just never really understood what parity was so I kinda overlooked that one. Alright well it'll be a while before I get the money for all 4 drives, but once I get them I'll benchmark both setups and post the results here. Thanks for all the info guys.
Oh and deathwish, that link was very helpful. Thanks

I had a raid5 array. Was fine, worked quickly and smoothly.
Big BUT..
Liking to overclock, I would often get BSOD's when trying new cconfigurations etc. And each BSOD would cause the computer to check the array for errors (specifically the intel matrix storage software).
While this check is happening, game load times increase, you have constant disk and cpu usage, you can just forget about running any type of benchmark as the results would be meaningless.
So I'd bare this in mind if you want to set up an array.
Myself I am now on a raid0 array, sure I still get the odd BSOD when i go messing about in the bios, but the computer no longer spends ages checking for errors afterwards. And as this is just a gaming computer, I really couldnt care if one drive packed up and I lost the info, I reformat often enough anyway, anything important I save to a 2nd external drive.

Hmm that actually seems like a good idea. I what HDD's are you using in your RAID 0? And I guess my programs and such on my comp arent all that important since I could always just reinstall them, and I already put all my important stuff on my external. Have you actually had any problems with HDD's dying in your RAID 0? Also, if a RAID 0 disk does die, do you just reformat the disk thats still there and buy a new one/get warranty on it? And afterwards just reinstall windows and everything? I've never had an HD fail on me before so im not sure what the whole process would be but this seems like a logical way to go about it I would think.
If the HDD fails, then you're pretty much always going to have to RMA it. Which is why a 5 year warranty is good. If you're in RAID 0 then you're also going to have to format all the other drives as they are now useless.
I'd wait for the replacement 4th drive before reinstalling raid 0 though. Just do a basic install of your core programs.

No, if you had 3 drives, 2 of which were in the raid0 array, one of which broke, all info on this raid0 array would be lost, the other 3rd drive (not in the array to start with) would be fine. These days, you dont really reformat as such with raid0, you just build it in the bios, and off you go
yes - this is a raid 0 drive mr computer
yes - this is the other raid 0 drive mr computer
yes - connect them together please mr computer
job done.

Currently I have 3 seagate barracuda in my raid0 array. Speedy.
In my experience with drives, they either break soon out of the box or are DOA than break many years down the line.
So if one of your drives were to die, you'd just RMA the bugger get a replacement, and rebuild the array in the bios. And install windoze etc as you say.
Clearly though, the more drives you add into a radi0 array the more chance there is for one of them to go wrong. Really though, for me and this gaming computer I'd rather have speed, than redundancy and long ass file integrity checks following a BSOD. But if you're going to NAS then raid 5 or raid1 would be much better.
Come to think of it, I dont believe I've had a more modern drive die on me. And I've used a lot of them in the last 15 odd years, what with computers for me, the family and even a server I had running when I was more into the unreal tournament `99 and `04 games. Had that puppy up and running well over ONE year, without any downtime or issue.
RAID 0 is sounding better and better lol. A couple more questions, does the speed of the array increase with the number of drives you put in it? And the total capacity of the array is the same as the total capacity of all the HDD's in it right? I think I already know the answers but I'd just like a knowledgeable person such as yourself to confirm it lol :worship:
