[Avid-L2] Re: Preferred Symphony platform

 

I've been migrating most (8 as of last count) of the boot drives on my various W7 computers to SSD. But my W7 MC Z800 Workstation is the last to go. My principle reason for doing it last was to build confidence in the technology -- and because I'd rather deploy SSDs for applications where data read/writes cycles are not excessively dynamic.

In the meantime, and just for shortform/online projects, I've been moving away from my 16TB CalDigit HDOne -- to a +/- 1TB SSD RAID0 which I put together with 4-OCZ Vertex drives using the internal Z800 Intel ICH10 controller mounted on the motherboard.

The drives take up no additional space -- as they're mounted in the two empty 5.25 bays in the front of the machine -- using 2 HP Dual 2.5" drive bay kits -- and they produce no heat or noise.

AJA System Test reports Write speeds at 639.2 MB/s and Read Speeds of 556.1 MB/s -- and they work quite well as my Avid MediaFiles drive.

Of course, TRIM does not work behind RAID controllers -- but if you over provision the array by 25% (formating a 1TB array as 750GB) -- then Garbage Collection seems to work just fine. And when it stops working -- you just have to Secure Erase the disks to revert them back to factory.

It took many months of research to make this move, and frankly, I was tempted to just go with a PCIe-based SSD RAID solution -- which would have bypassed the entire 3G SATA bottleneck and the involvement of a 3rd party controller -- in my case, the Intel. This can be especially important -- as current generation RAID controllers frequently misinterpret SMART information emanating from SSDs -- which can lead to false reports of degraded drives or arrays. But, I'm happy for now.

I'll eventually invest in the next gen of PCIe-based solutions -- and repurpose these four drives as boot drives for other machines.
