Does anyone have SSD's in Raid 0?

HDTune is a bad benchmark, because it tests with a queue depth of just 1. A filesystem will have much higher queue, for example the read-ahead when reading large files will jump to 8 or higher. This is important for any RAID, since RAIDs depend on multiple queue'd I/O's in order to process them in parallel. It cannot do that when there is just one queued I/O everytime, like when using HDTune.

The result can be lower (wrong) results. New versions of HDTune also have a "Files" benchmark, which tests the filesystem. This should produce usable results on RAID-arrays.

But testing sequential performance is dumb, real performance is measured in IOps and that's where SSD's shine. Sadly few free benchmarks use proper tracing&replay benchmarks to determine "realistic" performance of your drive or RAID-array.

There are no really good windows I/O benchmarks. There is iPeak suite/Rankdisk and IOmeter plus some retrace benches, but these are pretty hard to use as a consumer, they are more suited towards laboratory testing with a person with deep knowledge about storage. In Linux you have many more benches that focus on IOps performance, something i'm missing in Windows.

In general, you should work with a utility that tests on the filesystem, like ATTO and HDTune "Files" benchmark do. For realistic performance its still better to look at good reviews, because the tests done by these reviews are harder to simulate at home.

I'd love to spend 400 dollars on 4 SSD's but i got my raptor's for 20 bucks a piece so its not even worth upgrading.
