Hi, SSDs have low latency but a high price per GB, Traditional hard disks have high latency, but high sequential read/write speed and low price per GB. Is possibile to use a SSD for metadata, which requires many seeks and is relatively small, in a special "RAID mode" with a traditional hard disk for the extents of the real data? A cheap but performant SSD (maybe 32 GB) + a big and fast HD (maybe 1.5 TB, or two in RAID0 - 3TB ), wouldn't create an array much cheaper than a ssd-only array of the same size, and much faster (in not-only-sequential workload) than one or two traditional HDs in RAID0? Would it work? Thank you for your precious time! Massimo Maggi [email protected]
