Installing of two SSDs in Mac mini mid 2010 (core i5 2.3GHz)

Second one works fine...

If I install one of the SSDs on the second drive bay it is recognised as a SSD, but I'm not able to format it.

Doesn't matter how it is installed: only the SSD, or SSD + HDD.

If the SSD is installed on the "primary" port (this one where the original hdd is factory installed) - it works.

If I move it on the second "free" port - it is recognised, but disk utility is not able to do anything with the SSD.

If SSD is already formated - it is accessible, but always when you try to copy any data from/to this SSD - it always returns IO error...

If the original HDD is installed on this port - it works fine... and this SSD works fine if it is installed on the "primary" port.

Mac mini mid 2011 models has no Optical drive.

Both two ports are 6GB...

I have found some sources, where they says this is a problem of OCZ....

This is the port where SSD works:

Good work?

My mac still doesn't work by the way I want 🙂

I really want to know which brand of SSD I need to buy... just to be able to configure two SSDs in RAID0...

And you think if I order two of these, they will work "together" in my mini?

I heared from many sources the problem is typical for OCZ.... OCZ knows about the problem, and they have promised a firmware update... see what will happend 🙂

Still same issue... now, i have upgraded my mac mini to 2012 model, with one OWC Mercury Extreme Pro SSD and in second bay - the original HDD. With two OCZ SSDs only this one in the primary bay works.

OWC support told me it WILL work with two of their SSDs, but this is not tested by me...

As I remember, i only the SSD is installed, there is no problem and doesn't mattre in which bay you will install it.

Problem comes when you try to install two SSDs.

My idea was to install two SSDs in raid-0 for better performance.
