I couldn't find relevant data to compare. I'm thinking of buying either 4 X 60 GB OCZ Vertex 3, or 3 x 120 GB Vertex 3 MAX IOPS Edition. Which setup would give better performance?
Thanks.

I've no idea about best performance, but are you quite sure about RAID 0 on that many drives?
The Sandforce chipset in the Vertex 3 is not known for being very reliable. With 3 or 4 of them combined, there's a real chance of full dataloss.
Using OCZ Vertex 3 drives will guarantee you cheap thrills down the road: these devices are unreliable even without the added excitement of RAID 0. Of the two choices that you have offered, 3 x 120GB MAX IOPS is the better one. However, I would recommend neither option.
Instead of putting multiple SATA SSDs in RAID, consider a single PCIe SSD. For example, the RevoDrive 3 series RVD3-FHPX4-240G would deliver:
Depends entirely on your workload and what kind of IO you are doing.
Lots of small random I/O is going to be faster with the MAX IOPs drives.
The Vertex 3 60 GB drive is somewhat terrible for small random 4k reads for example, so MAX IOPs will outperform (somewhat). (The regular vertex drives are terrible for my database workloads, at least.)
The drives are all plenty fast though for large sequential read/write, so, for lots of sequential large read/write, just throwing more disks at it will speed things up.
However, you will need to benchmark against the actual type of load you have, in order to determine which solution will work better for your needs.
There are spec sheets on the OCZ site that has IOPs details and MB/s read/write benchmarks.
I've did some more research and decided to go with 5 x 120 GB OCZ Vertex 3 MAX IOPS edition in RAID 0 array. I'll add more ram to the server and this will cover the reads. For disk writes 120 GB MAX IOPS gives better random 16K performance.
I would personally go with a Crucial M4. But is there any reason you want SSDs only for storage? For the cost of those SSDs you could get quite a few 1tb drives and run them in RAID 50.
