What’s the fastest read and write speeds I can get, internal or external to a Mac Pro – on budget
I last specked a mac 12 core with 3 internal hard drives – at that point I could play back Red’s 4k r3d files. But since then SSD’s have come into play. Should I put three ssd’s inside a mac and if so what speed read and write will I get? Or should I buy an external raid carrier – like sonnet and connect via esata at 3gig (or thunderbolt) and yes, budget is always limited so I need a best-buy option. By buying 2 quad sonnet boxes in the past and going in via esata I got about 500MB read and write – had I doubled the drives I would have got 900 or so. But I now need a lot of read write in Raid 0 as I’m in 3D at 4k. Any ideas?

Not if you were working with only two 3G eSATA interfaces – those max out at about 275MB/s each.
If you need/ want over 550MB/s, eSATA is far from the best choice. An 8-bay MiniSAS box with a controller can be had for about $1K – $1.5K before you add drives, and give you close to 1GB/s speeds with the right drives.

By mini sas controller, do you mean a card that takes in the output of the min sas box? Sorry, I’m unfamiliar with this stuff (also, previously I had a card with 4xesata in)

For best performance, get a SAS card like this:

https://www.promax.com/s-67-fastmaxfx8.aspxShould see 700-900MB/s…
For more speed get a bigger box like this:

~1000MB/s -
Thanks for this – but: has anyone any specs on internal raid 3 x ssd’s read and write even if it’s just using a Kona tool. My current 3 x 2T hard drives read about 340 MBs – -so what do 3 x ssd’d do?
Thanks for all answers up till now.

I go with Alex,
and I don’t think you get more than 500 MB/s speed out of an SSD array. But you can try. Interesting. Tell us, how it works.Rainer
