Mechanical Cache Recommendations??

[andymiller]

 

SO I acquired a new Supermicro dual socket 2011 2u chassis with 12 front bays and a sas expander.

 

I trialled it for a few days with dual 250gb Kingston hyper ssd's that I had lying around, given I know the performance of these drives isn't the best and due to having lots of data to transfer over to the box I decided to remove them and throw in 4x 2tb mechanical sas disks I had lying around and build a raid10.

 

Although the drives are from 2013 i'm impressed with its overall responsiveness and considering long term keeping a 4 drive raid 10 for cache.

 

The issue I have is the mainboard only has 2x sata3 ports and the onboard sas is LSI 2308 so using 4 ssd's is out, so im looking to buy some up to date mechanical drives around 1-2tb and wondered if anyone else is running mechanicals and what speeds you are getting??

 

Thanks.
