SSD RAID 0 scaling questions, cost/performance questions

post #1 of 4
Thread Starter 
I am looking to set up a very fast solid state drive or array, and have a question:

1. What can I expect to scale with RAID 0, and how well? From some stuff I've seen sequential performance seems to scale very well, nearly 100% improvements. But what about 4k, especially 4k reads QD1.

What are your recommendations for the fastest/best drive/array for somewhere between $200-$400? I know the budget isn't very specific, but I'm really looking for a sweet spot here, and the combination of 2x capacity and potentially, nearly 2x performance of RAID 0 looks mouth wateringly good.

Currently, my options are open, and I'm looking at everything, but the drives that really stand out as far as price/performance are the Agility 3, Vertex 3, and Crucial M4.

an ssd still rocks, i'd take one over any solution. why not run two smaller ssd's in raid 0 and get the combo benefit?

well the thing about 4kQD1 is that it is just that: a request of one small file that is 4k. That is held on only one drive, so you cannot boost the 4kQD1 regardless. It will always be the speed of your base devices' 4kqd1. The best that you can do is not add latency to the request.
At 4kQD2 you will see twice the speed however, as it is requesting 2 files, thus you get one from one SSD and the other 4k file from the other, thus you double speeds at everything OVER 4kqd1.
the great thing about SSD raid is multitasking, virus scans, etc etc. they really rock. Video editing, photoshop, acad, things of that nature are WAY faster. there is a benefit to games, but mainly just the smoothness factor in-game, no waiting on the loading.
Go M4 in raid 0 for real performance, regardless of the type of data.
