Quick question regarding storage solutions

post #1 of 11
Thread Starter 
I'm currently in the process of saving for my gaming and entertainment rig and have a question in regards to storage. I am going to purchase two 500g 7200rpm 64MB drives for main storage and run them in RAID 0, my question is can I purchase two 60g SSDs for windows and my 2 main games and run them in RAID 0 also?

If that's not possible it would probably be better to RAID 0 the SSDs and just purchase a 1 or 2tb drive for storage, correct?

Thanks for any input!

In my opinion, your best option would be to put the HDD's in RAID0 for the biggest performance boost, but just purchase 1 larger SSD (around 120GB) and set up your OS and games on it.

You won't see large benefits using SSD's in RAID because they already perform so well. Also, if you put them in a RAID, you won't have TRIM.

Just my 2c worth...hope it helps,

Thanks Rich, that was actually my original plan so I'll take your advice

Why would you run storage in RAID0?

If your OS and programs are on the SSD, the RAID0 will only serve to increase the probability of fault on your storage volume. You would be much better off leaving the drives individually and mirroring one to the other (manually) as backup.

RAID is not a form of backup, and RAID0 is actually detrimental in a storage-only scenario. You gain performance where you don't need it, and double the risk of losing your data.

That is what is generally always recommended on WoW's gaming/hardware forum. Guess I didn't know better. Thanks for your input!

raid 0 (especially short stroked) is very fast and the best alternative to a ssd

However as a storage drive I'd run raid 1 (safest 2 copies of files on storage drives) or just a single large drive (no less risky than a raid 0 setup except you have 2 drives with a possibility of failure instead of one ..... contrary to popular belief raid 0 is not much more prone to failure than a standard hd, just there are 2 drives that COULD fail)


And to answer your question you can have 2 seperate raid configurations
so you could have the ssds in a raid array and the mechanical in a separate raid (if you wanted)

Well, RAID 1 is redundant, but *all* changes are mirrored. If you goof and delete something by accident, you will have no backup of it on the second drive. In my mind, it is better to use individual drives with no mirroring.

RAID0 in theory is only as secure as the weakest disk in the array. The danger could be overstated, but putting your data on individual drives will reduce the possibility of putting your data on the weak disk. The whole point being that even if you had two individual drives and one fails, you have your backup on the other.

With RAID0, there is no redundancy and no backup, you lose anything, and you lose everything. You are right about RAID0 not necessarily making failure more likely on either disk compared to being separate.

I personally use raid 0 primary with a F3 1tb single internal and a f3 1tb in external dock

However using a individual drive, what if you use the "weak disk" as the single drive?

Raid is no more prone to failure than single mode, just there are 2 drives that COULD fail. But its the same if you have a single drive, if it fails you lose data

Not if the single drive is manually mirrored to another drive. I use 3 drives in RAID 0 for my OS and programs. All my media is on a 1tb drive that I manually mirror with another 1tb drive.

So say you have 2 disks that you can predict the failure of, one (disk A) will fail in 3 months, one (disk B) will fail in a year.

If you have both disks individual from each other, and you have all your data on Disk A, and manually copy it over to Disk B each month - Drive A will fail in 3 months and you will have your backup on Drive B. All is good, replace Drive A and move on.

If you decided to RAID0 these drives for storage, all your data will be split between the drives and Drive A will fail in 3 months taking all the data on Drive A and Drive B with it. No backup, total loss.

The choice to RAID isn't increasing the failure of Drive A (still 3 months), but it is increasing the likelihood that your backup solution will lose your data.

I am not saying raid 0 your primary with no backup

I'm saying raid 0 your os and back it up as you would a single drive
