RamDisks... current status?

With all the SSD talk around... are RamDisks other than the HyperOS Hyperdrive (5 or 5M now) being improved? There seems to be so little info about this on the net. Do you know about advancements in these directions?

It seems a dead end to me. RAM is volatile and therefore no matter how many advantages it has it will always be an inferior storage medium.

Acard is the only in consumer area now. HyperOS buys from them.

RAM+battery+a drive where you can flush RAM contents on power loss is not in any way inferior. That's the way all ram disks work, except for iRAM, which is dead for long. And advantages...yes, there are.

Well... actually I doubt it will stay competitive. The HyperOS 5M with 12GB (6 DDR2 modules, each 2GB) will cost you around 500 Euros as the cheapest RAM drive option and will "only" give you 175MB/s read speed. That compared to a RAID0 of two OCZ Vertex SLC SSDs, each delivering more than 200MB/s and a capacity of 60GB will get you a lot more capacity (5 times as much) and better performance for less money (around 450 Euro plus eventually a RAID controller). So yeah... I kinda also think it's a dead end if there's now significant improvements made soon.

All the manufacturers are definitely going to flash. At the high end, Fusion-io recently announced an SSD with 1500mb/sec sustained read throughput, 1400mb/sec sustained write throughput. That's 5 times faster than the maximum theoretical speed you can do over SATA and requires an 8x PCI-E slot as a result. With throughput rates like that currently representing the high end, it seems apparent that there's no reason to waste time with RAM based technology anymore.

About RAM SSDs being useless:

RAM, Flash, HDD: they all have their niches.
Many manufacturers are going to flash, but AFAIK none gave up RAM business it was in already.
