RAID01 vs RAID0 + RAID1

post #1 of 6
Thread Starter 
okay i guess first of all i must say i'm writing with no first-hand RAIDing experience whatsoever.
that said, i'm also assuming that it is possible to RAID 0 -and- RAID 1 simultaneously (haven't yet gotten around the trying this)

i'm asking for feedback and opinions here.

well, after losing all the data on one my hdds and reading up on the RAID function to which my mobo is capable of.. there is no way i'm not going to grab this opportunity by the <insert body part here>

but i'm now having a hell of a time deciding on what to do...

i've been thinking of getting the WD Velociraptor (300gb), and altogether detouring the RAID0 route, and simply using 2xWDFALS1001's in RAID1 for backup data.

but the cost (just under $200 via newegg) is a bit off-putting as well as the relatively low 300GB capacity.

so i'm thinking it would be more cost effective to simply RAID0 my existing 500GB WD, with another 500GB from newegg (~$80)... this would give me comparable (debatable) perfomance in contrast to the velociraptor as well as ~3x more capacity (1TB total.. right?).
sounds good enough to me.. as prices will likely go down by the time these drives fail..

so i'm leaning towards the 2x500GB RAID0 + 2x1TB RAID1 for a total of 2TB of space for the price of a 500GB + one more 1TB HDD (total of ~$200)

but wait... i learned that i could actually RAID 0+1...
with a RAID01 i think the setup (if possible?) would be a
500GB + 500GB mirrored with a 1TB HDD....
right?
or do i need an even number of HDDs?
or perhaps to partition the 1TB into half?
or do i even need 4 identical HDDs?
(i.e. 4x1TB HDDs to equal a total capacity of 2TB of striped,mirrored memory?)
i would get the same space of 2TB with the RAID0 + RAID1 setup at a small cost (not completely mirrored..)


ahh i'm going mad trying to decide what to do.. someone hook it up with the feedback!

RAID10 is a mirror RAID0 array. You need 4 identical drives usually. If the drives used for the mirror portion are bigger than the striped portion, that is OK. AFAIK you can't mirror a RAID0 onto just one drive.

do you know if i could RAID0 my 2X500GB for the OS and games..
and then RAID1 my 2x1TB for storage?
it seems more efficient in theory if you don't mind losing the RAID0 data

I'd raid 0 the 500gb's, then raid 1 the 1tb's. Backup the raid 0 array to the raid 1 array, and also use them for extra storage.

RAID10 is not a good solution for Desktop PCs.
As you shouldn't use differnt Disks in a RAID Array it requires 4 identical Disks.

And more important if one fails you have to buy an Disk identical (at least in Space) to the other 3.
Imagine a fail in 5-10 years: you could buy the same disk again used or a new (and likely bigger) one and wasting money as the tech level involved.

Also rebuilding and RAID Array takes some time.
While Vista or any 3rd party backup solution does backups in the background and the backuped data is accessible very easily.
And you be bound to use nVidia Chipsets in the future or lose the 4 disks.
An intel or AMD chipset based mainboard will not recognize the Array and you have to build it up new (which involves losing the array's data).


You better use a RAID0 Array with 2 identical disks and let the rest as single Disks.
And put only unnecessary data on it's partitions (in case of Disk fail or more likely Mainboard change to different platform).
Or better keep it backuped by Software automated or by hand copying files.

thanks for the input..
however, i just went and bought the velociraptor lol..
i really couldn't help it.. i guess i talked myself into it by just bringing it up.. =\\
i guess it saves me a few sata ports as well.
plus i really want to use RAID1 for backing up my data files as i really don't want to go thru the pain of losing them again.. so i think this is the best compromise as i still am not sure if i could RAID0 the 2x500GB -and- RAID1 the 2x1TB (i.e. a RAID0 + RAID1; not RAID01)
