SSD vs HD's

[bobbarley]

I'm in a little debate with someone over storage devices.

I believe that an SSD is the fastest. He believes that two hard drives in a RAID 0 configuration is fastest.

I've been looking on the net and I can't find a SINGLE benchmark or evidence to prove one way or another which is faster in real world tests, such as loading Windows, games etc.

Has anyone a link to any proper comparisons. Or know one way or the other which is faster? I did read some information that suggested even two Raptors in RAID 0 can't beat an SSD.

For transferring sequential data (like a video file), 2 modern HDDs in RAID 0 on a good controller can performs as well or better than a modern SSD.

However, if you start working with random data (like loading up an application), this changes entirely and an SSD is much faster than a mechanical raid 0 array.

Since for general use random reads are a big factor, then an SSD will perform a lot better than two fast mechanical drives in RAID 0 in almost all situations.

And of the SSD's the Intel drives are the fastest at random reads/writes but also very expensive.

RAID 0 increases access time so it should slow things down in theory.
