Hybrid SSD/HDD storage solutions

[ddrueding]

We need a place to dump these, as there are more and more on the market.

My interest stems from accelerating large file shares. Getting 100-500GB of SSD in front of 2-6TB of HDD would be something I could sell a lot of.

OCZ just announced the RevoDrive Hybrid. An all-in-one solution that would interest me at larger capacities for my low end.

Intel's Smart Response caching allows me to spec the SSD and HDD, but doesn't support RAID arrays.

ZFS would allow me to stick whatever SSD I want in front of whatever HDD array I want, but that is too complex for me.

Anything I'm missing?

Marvell has something like this built into one of their controllers I think. I posted about it some time ago. http://www.storageforum.net/forum/showthread.php?t=8508&highlight=Marvel

Thanks Will.

So there is Marvell HyperDuo - similar to Intel Smart Response (no RAID)

We also can't forget the Seagate Momentus XT and Samsung Hybrid FlashOn - both laptop HDDs with SSD cache. Both too low capacity for my needs.
