T121 is only supported by ARC-188X series cards, for older models you need to go with T113 as T121 simply won't work with those.

Usually, anything above 8th port is routed through the expander. I have been selling Areca PCIe 3.0 cards for several months already. Could get you one unless you always shop Newegg. :)

@Ducs Areca controllers, at least the 12/16/24-port cards use a built-in expander. That external port you have mentioned is used exactly what you would need it for - for daisy chaining a bunch of external enclosures. I still do not get it as to why you need an In/Out port on a controller.

@mikeblas Adding drives into a config one by one, the drives increase vibration being produced by the setup. When vibration exceeds drive's tolerance threshold drives will start producing random timeouts and if they are part of a RAID set, then controller will start dropping drives out as soon...

There is a good chance that vibration limits your ability to add more drives in the setup. What kind of drives do you have? Are they all identical? Try what VR suggested - remove the drives from your case and hook them up to the controller while they are all placed on a hard and solid surface.

Pull just the drives out of the 847J, leave everything else connected. If you get the stability back, then start plugging them back in one by one and checking for stability between each drive. Out of curiosity, are the drives of the same brand? Samsung? Seagate? what model? If you get the...

Since you have Disk Write Cache enabled, it explains why the writes are so much faster. Yet, I'd certainly expect faster reads from 8x SSDs in RAID0. Have you tested the drives individually to see if one (or possibly more than one) of them cripples the speed?

@mwroobel Thank you! Appreciate it!

Those two web sites have nothing to do with me and I have no idea how reliable they are.

Yes, I handle most requests for Areca controllers from that account. Ship worldwide a lot.

Email me at [email protected] if you can't find them anywhere else. I could probably help you. Been selling Areca controllers for 7+ years now.

First of all, YES, you need to get rid of that drive! But not so fast. Update the F/W and all other filesets along with it. Since you do not know your RAID set initial parameters, it may take a few tries before you find the right ones. In order to be able to make another attempt to recover...

Do you still have that faulty drive in the config?

@ATWindsor Sure! That is why Areca calls these card 12/16/24+4 ports. It was working this way since 1680.

@Zerosum After all is said and done, try swapping the cable which you use to connect Areca card with an expander. It may be at fault. Also, direct connection between the drives and an Areca controller might shed some light on the problem as well.
