<Edited to add some more information on how SPC-1 works since there was some confusion based on the comments received>
We’ve been busy at NetApp… busy perfecting the industry’s only scale-out unified platform, among other things.
We’ve already released ONTAP 8.1, which, in Cluster-Mode, allows 24 nodes (each with up to 8TB cache) for NAS workloads, and 4 nodes for block workloads (FC and iSCSI).

(Edited: My bad, it was 2TB/s, up from 1.3TB/s, the solution has been getting bigger and upgraded, plus the post talks about the E5400, the newer E5600 is much faster).
What do you do when you need so much I/O performance that no one single storage system can deliver it, no matter how large?

There are some impressive new scores at storageperformance.org, with the usual crazy configurations of thousands of drives etc.
When looking at $/IOP, make sure you are comparing list price (look at the full disclosure report, that has all the details for each config).
Otherwise, you could get the wrong $/IOP since some vendors have list prices, others show heavy discounting.

I finally decided to spring for a SSD for my laptop since I hammer it heavily with a lot of mostly random I/O. It was money well spent.
I went for an Intel 320 model, since it includes extra capacitors for flushing the cache in the event of power failure, and has RAID-4 onboard for protection beyond sparing (there are other, faster SSDs but I need the reliability and can’t afford large-sized SLC).

Just came to my attention that EMC is finally joining the SPC (Storage Performance Council). As I’ve pointed in their past, their absence from this most standard industry benchmark was puzzling, kudos for rectifying this omission.
I do have some advice for EMC (and all other vendors that have already posted results):
