You cannot "upgrade" a 3,1 to a 5,1 as they are completely different architectures (the 5,1 is a very minor revision of the 4,1 and that's why you can flash a 4,1 to essentially be a 5,1).Excellent idea on the USB 3.0, and that will help with speed if I’m using this unit primarily as storage. Any suggestions on brand?
On another note, there’s a 3,1 locally available for $150 with the following:
- 2x 2.8GHz quad-core Xeon
- 10GB RAM (2x1GB, 4x2GB, 2 empty)
- ATI Radeon HD 2600
- 128GB SSD
- 750GB HDD
Is this worth picking up given the specs? You may be asking why I’m considering going in different directions. I’m enjoying getting into the basics of upgrading and learning more about these machines. So far, I’ve been able to do so for very short money, which I’d recoup easily upon selling the 2,1. How much better off would I be served longer term with a hooked up 3,1 flashed to 5,1?
I don't believe so. The 3,1 was essentially an update on the 1,1 (everything I say also applies to the 2,1 as the 2,1 was just a dual quad core version of the 1,1) model. It was not nearly the leap the 4,1 was over the 3,1. IMO the most significant advantage the 3,1 has over the 1,1 is official support for OS X. The 1,1 line ended with Leopard whereas the 3,1 ended with El Capitan therefore the 3,1 can, officially, support significantly newer software.Thanks for your thoughts, defjam. I’ve got my 2,1 headed in a good direction. Could this 3,1 far exceed it with some minimal investments in upgrades?
I’d also go SDD for one of the hard drives.
Thanks VS, and no, it is not my primary machine. However, it will be hard not to use a lot with the speed it seems to have and load of tasks it can handle.
Any other thoughts on my post/thread about the home network setup?
He's referring to two types of SSD interface technology:
When I say native support I'm referring to the ability to use it to boot a system. As the AHCI version is based on SATA it will boot in systems which support the SATA protocol (which just about every system made within the past 10 - 15 years does). NVMe requires firmware support which, until just recently, the 5,1 did not have. AHCI was a transition technology, didn't last long (relatively speaking), and has been replaced by native NVMe. Thus AHCI drives are much more difficult to find. NVMe is faster than AHCI but it's unlikely you'll be able to tell the difference in most instances. In fact I would say you're unlikely to notice the difference between AHCI and a SATA 2.5" drive for most things.
- AHCI - This utilizes the SATA protocol and is useable in systems which do not natively support NVMe.
- NVMe - This is a "native" interface for SSDs and requires the system to have native support.
Recently it became possible to upgrade the 5,1 with native NVMe support. I believe the upgrade results from the installation of Mojave. Definitely ask others for their guidance as I have not performed this upgrade.
There's no practical reason to do so for your use case. TBH a SATA 2.5" drive would be more than sufficient performance for your needs. You're unlikely to notice anything faster. If you've got the drives go for it, otherwise I wouldn't recommend spending money on it.Solid info. Should I RAID two NVMe drives in an I/O slot? Again, trying to balance cost and performance.

With the addition of native NVMe support to the very latest 5,1 firmware I see no reason why you shouldn't unless other factors are in play. For example if you already have a SATA SSD it's unlikely, for your use case, you'll notice the increased performance over the SATA SSD. Or if you're unable to upgrade the firmware (for example you do not have a metal capable GPU and therefore cannot install Mojave, the installation of which installs the NVMe capable firmware).Ok. Not even one blade startup drive? I may run out of room up top in the four bays unless I go 2TB across. There are a finite number of slots in the back for upgrades, but I was figuring boot drive was good for one of them.

I read through your post and I did not see where you referenced an error of mine. I'd appreciate if you could highlight it so that I know where I was wrong so I might learn from the error.Sorry to interfere, but Mr defjam is NOT entirely correct on this one. To understand this, you need to know about three speed stages in the 5.1.
-I read through your post and I did not see where you referenced an error of mine. I'd appreciate if you could highlight it so that I know where I was wrong so I might learn from the error.
Then why did you say I was incorrect instead of saying that your opinion differs from mine?-
"In fact I would say you're unlikely to notice the difference between AHCI and a SATA 2.5" drive for most things."

At least in my opinion, the difference is remarkable between SATA SSD and AHCI in a switch card.
Despite the fact it's my opinion the OP, based on his previously defined workload, will not see a benefit from NVMe over a SATA SSD I did say:For me it feels like the difference between a 2014 iMac and a 2017 iMac, -- something of that nature. But then again, "my feeling" is relative of course, I can not measure it, so it is highly objective. But since the OP might as well spend hundreds of $ for a regular Samsung SATA SSD, he/she might as well go the more up to date PCIe route. I just can't recommend a SATA SSD in 2019, - I just can't. That's my personal opinion. There are professionals out there that think, to invest in a 5.1 in 2019 is already questionable. So from that kind of view, beeing a die-hard enthusiast, at least get the latest tech possible, hence at least AHCI blade or NVMe depending on local availability. The only small weakness the 5.1 cMP has for me is the somewhat slow single-core performance, so my personal theory was always to compensate for that with avoiding bus-speed bottlenecks on the SSD-CPU transfer. Hence the importance to use the max on MB/sec with the lowest invest, which is why I stranded on the Crest card. But thats just me..
