I will not accept your apology; it's unnecessary. To think that you or OP were the cause is insane. I was glad to see the post since it pointed out that the deal was for TWO cages and not one. So I took the deal. Secondly, I was watching that sale for months and the price fluctuated from $75 to $125. Again, your apology, while appreciated, is unnecessary@MountainDew - yes- but I only had one unused SATA to test with-- but it linked at 6 Gbps. I did not test beyond that-- was a little short on time. (Work keeping me busy right now!!)
Im beginning to think there may be more than one version of the SA120 (i.e. Hardware revision, etc), because while i was able to get 6, i have no doubt that the other poster was only able to get 3. (Now that i think about it- could be drive limitation in his test?? I used a spare (brand new/right out of the box) Samsung Pro 950 SATA when i checked. The SAS ones i have in there are 6GB as well, and appear to be operating fine/at full speed. (Don't have model w/me. They were the newegg special late last year.)
In any case- sorry for stirring up pricing changes by posting- was never my intent. I just thought others might be interested, as they were something i had trouble getting when i really wanted a pair.
I did have MSM already and it's showing that, while the drives are capable of 6Gb/s, the negotiated speed is only 3. What's funny is that I can manage the speeds of my other non-ssd drives but not the SanDisk SSDs I just bought.Actually for verifying, install Megaraid Storage Manager and select the drive in MSM, its properties will show 3Gbps. That will confirm what speeds the disks are negotiated. And then any kind of disk benchmark (ATTO or CrystalDisk) will show 3Gbps speeds max. When I had the cage with me I ran tests mine with Kingston V300, Samsung 940 Pro, Samsung 940 Evo with 9260-8i, 9280-8e, 9280-4i4e etc. I have only tried them with LSI cards. If you are seeing 6Gbps in MSM, then I think the one I had was an older model may be.

I bet it will be the same (3Gbps) for any SSD you put on it. Are those results for a single drive or for the stripe? I'm thinking its the speed for the stripe? How many drives in the RAID?I did have MSM already and it's showing that, while the drives are capable of 6Gb/s, the negotiated speed is only 3.

Ok. that's what I thought. Whereas you should be seeing those numbers for a single drive when negotiated at 6Gbps. That's the problem with this cage and the reason why I should abandon it.Two drives in a stripe
I would say I'm a light user; in the fact that I'll have 4-5 VMs and my media stored on the DAS so I doubt I'll max out the capabilities. However, I will be hitting the forums at Lenovo. It's crazy that they advertise up and down how everything/port is 6Gbps but the SSDs won't negotiate at those speeds.Ok. that's what I thought.
