You can only consider PCIe connected SSD drives like SuperTalent's and FusionIO. though they may actually be more expensive and for your application, you do not need a lot of space. -T On Mon, Jan 4, 2010 at 8:30 PM, Adam Megacz wrote: > > Thomas Fjellstrom writes: >> If I had one I might use it as a fs-cache. > > I'm not sure it offers any advantage over plain old system RAM in tha= t > capacity; I'd be just as well off putting those DIMMs on the > motherboard. > > I can't use plain old system RAM for a journal or a write-intent bitm= ap > because system RAM is wiped out in the event of a power failure. > > =A0- a > > -- > To unsubscribe from this list: send the line "unsubscribe linux-raid"= in > the body of a message to majordomo@vger.kernel.org > More majordomo info at =A0http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
