then I worry about running out of drive space if there is a lot of transcoding. so I created a vhd in spinning drive and then mounted as another drive

then created a spanned volume with the ramisk and the new hdd volumne, so if it ever exceeds 10GB of scratch space, it will just span to the 100gb hdd part.

I am sure the different layers will cost a bit of speed, but it should still be faster than spinning disk

not bad for 1GB test

Is wear on an SSD really a huge concern anyway? at least in a home setting I doubt you would ever wear through an SSD during normal use for the life of the drive.

It is an issue if you are using it as a temp drive that keeps getting written and erased. The files only live til the end of streaming session. Plex writes hundreds of 4MB files as it transcode to the target resolution. Then chucks them when the streaming is done. And that is one stream. Whe you have two or three streams going, you are basically doing 4MB random write test.

pointless. SSD would saturate the backplane. Load up on ram. Wish I can afford to max out the ram on my PE R710, it can go up to 144GB :awe:.

The idea is mostly for redundancy than performance. If a drive dies you just pop a new one in with no downtime. With SSDs I'd probably use raid 5/6 instead of raid 10 as well, though not sure what is typically done for SSDs and raid. I kinda want to see what the rebuild time would be on a raid 5 using SSDs though... I bet it would be awesome. :D

Though something like ZFS probably makes more sense than raid. I still need to experiment with that one day. ZFS has a bit of extra overhead but with SSDs you would probably not even see that. When the actual SATA bus becomes the bottleneck, then you're doing pretty good. :p

I want a backblaze pod.

Wish there was a setting in PMS for win to transcode to memory and key is worry about paging.

Oh me too, I saw those and I was in awe. I could take the drives out of my IBM SAN and put them in there. The issue with the IBM SAN I have is you can't just throw in any hard drive in there, BUT the drives themselves are still just regular SATA drives so you can put them in anything else.

Those pods arn't cheap though. D: Really I'd be happy with just finding a card that allows for having that many ports on a single machine, then build my own pod like system. Just finding cards to have 24 ports was hard enough when I built my 24-drive machine. I ended up having to buy 3 special sata cards off ebay that allow to flash the firmware to jbod since everything on online retailers were raid cards, I just needed more sata ports with nothing fancy since I do raid in software.

On subject of ram disks, I think that file server I have does support like up to 64GB of ram. I should load that baby up so I could make a ram drive. Not sure what I'd use it for but I'm sure I'd find a use. :D Linux makes it pretty easy to make a ram drive too.
