...equential write QD32 147MB/s (2 x HDD RAID1) 156MB/s (1 x NVMe, 2 x HDD RAID1) The write tests give near identical performance with and without the SSD in the array as once any cache has been saturated, write speeds are presumably limited by the slowest device in the array. Sequential read QD32 187MB/s (2 x HDD RAID1) 1725MB/s (1 x NVMe, 2 x HDD RAID1) Sequential read QD1 162MB/s (2 x HDD RAID1) 1296MB/s (1 x NVMe, 2 x HDD RAID1) 4K random read 712kB/s (2 x HDD RAID1) 55.0MB/s (1 x NVMe, 2 x HDD RAID1) The read speeds are a completely different story, and the array essentially performs iden...

I called Digium today and hear some neat nifty music on hold that isn't included with Asterisk.. anyone have any idea what it is.. and where I can get it (if it's in the public domain)?
