October 4, 200916 yr Ballpark figures. I know that right now I'm getting average upload speeds of 14MB/sec which is from what I understand as good as it gets for Unraid writes. Now I insert a 1GB WD Caviar Black (as weebo suggests) into array. I assign it as cache drive. I now upload a file with the cache drive setup. What should I typically see now for upload speeds.

Now I insert a 1GB WD Caviar Black (as weebo suggests) into array. I assign it as cache drive. I now upload a file with the cache drive setup. What should I typically see now for upload speeds. I believe with the beta version, the speed is not much faster. With the stable release, I believe the speed is about 3x-4x faster. It can never be faster then your network can support or your drive can write. It's hard to tell an appropriate speed. There is not a specific benchmark that everyone uses. Many people just copy files with vista. I do not have vista, so I use rsync. I would estimate mid 20's to lower 40s. I do not remember anyone posting about faster speeds then that. With my 1.5TB parity drive, rsyncs from one machine to another can spike at 22-30Mb/s, but then it could stall and drop to 12MB/s, then jump up again. If I set my bwlimit flag I can keep a steady rate between 12-20mb/s on a parity protected drive. Just to toss some numbers, I did direct network to network transfer, (no hard drives). and on a 1GB network connection I got 990mb/s as a benchmark from one PCIe network adapter to another PCIe network adapter. From a PCI-X (Celeron M 1ghz) to a PCIe unRAID machine I got 770Mb/s. This was purely a bulk network transfer. When Samba, usershare and filesystem come into play all bets are off to this sort of raw transfer speed. Maybe one of these days I'll try an NFS and/or samba mount with DD to get a feel for it.
October 4, 200916 yr Very informative Weebotech. Thank you. Sounds like it might be worth it. I'll read through the post Joe sent and keep in mind what you've said. By the time I make a decision, hopefully Unraid 5 will be out and SSD drives will be cheaper
