These disks run pretty hot and are noisy, but look at the amazing speeds I get writing to a parity protected array without cache. I'm getting 90+ MB/s write speeds. These 7200 RPM disks are crazy!

I'm using intel nics both on the client and on the server. With another desktop with a realtek nic I get less than 60 MB/s write. So invest in intel nics

Server specs:  ASRock - E3C224D2I, i3 4160, 8GB DDR3 ECC RAM

Client specs: Asrock H110M-ITX, Pentium G4400, 4GB DDR4 RAM

That's a very nice speed!

 

I'm use mostly "green" disks, have one server with 5900rpm toshibas and they also perform very good, around 70MB/s sustained writes.

I thought you were doing that when parity protected.  That would be awesome.  Most systems should do close to 100 mb/s with good nics on gigabit lan.

 

Edit : those are parity protected speeds, wow.

Those are parity protected write speeds. Most users get 30-40MB/s!

damn that's impressive.  i wonder if an all hitachi nas array would see similar speeds.

I could demonstrate those speeds, and even higher, on 2-3G files. But,  it doesn't have much to do with the speed of my drives. It's due to the 16G of memory in my server.

Yeah, that was not a great example, since you’ve used a small file, but these disks do have a great write speed, on the 1TB model I averaged around 75MB/s.
