It makes sense. In the end, simplicity is almost always the best option for global productivity.

Even if you were to save a few sec at each open with a Raid 0, think how the time you will waster when the raid array goes wrong (not "if", "when").

cheers,

Thanks for the article… Interesting, as it goes beyond synthetic benchmarks.

Another thanks for the post.

The article was well done but unfortunately limited in scope. Even still, they showed as has other similar tests that a single higher capacity SSD will outperform a raid 0 array using 2 smaller capacity drives. This is not really news.

I’d love to see a similar test but done to show optimal raid 5 array using SSD. RAID 5 arrays do not deliver a notable speed gain until there are at least 4 drives in the array. I dunno if SSD drives would aid or hinder this kind of array, but generally with RAID 5 one gets redundancy, and with enough drives in place, significantly increased performance.
