ReadyNas Pro business Edition - How to install SSD and use Tier
Hi all, I have a ReadyNas Pro Business Edition (6 bays) I upgrade the CPU and RAM. At the moment I use the NAS as a Core for Roon and I would like to use a SSD for tier to store all the Roon Metadata...

While that is plenty fast enough to keep up with sustained transfer from hard drives, it's not going to push an SSD to it's max speed. About half for most, in fact. So, before you invest in this plan, you need to assess how much speed you will actually gain.
I agree.
SSDs don't have any seek time, so if you have a lot of files than either an SSD array or ReadyTier should significantly improve folder browsing.
Large file transfers are already limited by the gigabit ethernet speed (which is lower than SATA 2), so you won't see any improvement with them.
Thank you for the explanation. I will have to find a way to attach the SSD in the HDD drive cage first.
As for backup I have a external 8TB USB drive which I make a backup of all my share folders once in a while with the ReadyNAS backup features which is a bit slow but it's working.
You're going to need somethng that's specifically designed for servers. the problem is, most of them only have side-mount holes and the legacy NAS caddies only have bottom holes. Neither Dell nor Supermicro ones will work. There are a couple varieties of HP adapters that look like they will, but they tend to be expensive. I just took a quick look at eBay with a search of "server 3.2 to 2.5" and "HP 3.5 to 2.5" there are some for sale at a reasonable price that should work.
I got to thinking about this after I responded. The Pro BE (and all derivatives of that motherboard) has an Intel ACH8 family SATA controller, which is only SATA 2.0 (3Gb/sec.). While that is plenty fast enough to keep up with sustained transfer from hard drives, it's not going to push an SSD to it's max speed. About half for most, in fact. So, before you invest in this plan, you need to assess how much speed you will actually gain.
And if you decide to go on, don't waste money on the fastest SSD you can find.
The specs I have found for all the systems that originally ran RAIDiator 4.2.x say Serial ATA-300 (aka SATA 2.0). It makes sense for the time frame of their release (at least for most of them) but I don't know if that was an OS limitation or true of all the hardware. I have run lspci on a Pro6 and can say without reservation that it has the above controller with the hardware limitation.
