I think the DDR drive has a battery and can dump to a cf card. -B

And you are confusing throughput with latency (in a sense). Yes, my raidz2 pool is much faster than GigE, measured in pipelined, streaming throughput (for those old fogeys like me, think good kermit / zmodem). Yet it still sucks for small non-pipelined synchronous writes, such as those triggered by NFS + tar (think xmodem *shudder*). So spending around $150 for a greater than 10x performance improvement makes a hell of a lot of sense. And yes, spending even more on an ACARD flash backed DRAM solution would probably make things even faster, but I was feeling cheap ;-) As for the DDRDrive X1, it is not a solution I would recommend to anyone in its current state. If it gets a supercap / battery that enables it to dump its data to non-volatile storage following a power cut, that will change, and I know they have taken our feedback and are revising the product. -- Carson _______________________________________________ zfs-discuss mailing list zfs-disc...@opensolaris.o...
