speed comparison raid 0 SAS or SSD

[233]

looking at cobbling together a new rig shortly to replace my aging p35/q450 combo and i fancy adding a bit of fast drive action into the mix

options are


SSD + 2tb for storage


pair of 2tb drives in Raid 0 (dont need to worry about loss of data as everything major can be downloaded quickly steam etc)


or the darkhorse, some sort of SAS setup

for what its worth i like quirky things and yes everyone will say just go the SSD route but i fancy doing something differet,

can anyone advise on how the above compare for speed (broad generalisations as i know i'm not being specific about what i'm thinking about going for)

Option 1, without any hesitation. Personally I don't see why you'd put such large drives in a RAID0 array? If you need speed, then get smaller drives in RAID0 for windows and apps, then a larger drive for storage. Storing files isn't going to require RAID0 speed, and personally I'd rather not double the risk of failure and data loss on my storage drive.

SSD + 2x 2TB in RAID1

Typically a 7200RPM hdd will write around 100MB/s and if there's 100% efficiency then in raid 0 it would be 200MB/s

For around £100 you can get a 60GB SSD which can write more than 400MB/s

So you're going to get at least double the speed with the SSD.

If you're not bothered about losing your data then the SSD for boot + a few apps along with two drives in raid 0 sounds like the best idea for your needs.

I've had hard drives which are still running strong after 6+ years use so I don't think failure is that big of an issue.

If you want to be careful then if you have any pictures you could always pick up a small external HDD (or even flash drive) and use that for anything you don't want to lose.
