Hi list, Thanks a lot for your very helpful feedback! > I've tested MD1000, MD1200, and MD1220 arrays before, and always gotten > seriously good performance relative to the dollars spent Great hint, but I'm afraid that's too expensive for us. But it's a great way to scale over the years, I'll keep that in mind. I had a look at other server vendors who offer 4U servers with slots for 16 disks for 4k in total (w/o disks), maybe that's an even cheaper/better solution for us. If you had the choice between 16 x 2TB SATA vs. a server with some SSDs for WAL/indexes and a SAN (with SATA disk) for data, what would you choose performance-wise? Again, thanks so much for your help.
