Gone - 3.84TB Micron 5100 ECO SATA SSD - $250 OBO (eBay)

[Evan]

They are pretty poor performing drives, for sure aimed at cheap storage and they are SATA , i have some, just use them for regular storage like photos and files, replaced spinning disks good while back. For that they are good.

After SSD firmware update, write performance increase to perform like a regular SATA 3 SSD now.

The 4kb read performance is awful, but its at least still significantly faster than a hard drive.

Long shot, but I have a little time spare... If anyone wants some RAID performance metrics, I have 8x of these in RAID6 on a PERC H730P in a Dell PowerEdge R340 with a E-2136 and 128GB of RAM that is not being provisioned for another day or so.

I can do a quick generic Ubuntu server install and run some scripts (or just a few FIO runs), write in detail what you want below (including PERC write-back/write through preference, read-ahead settings etc) and I'll try to bang it out before I deploy it.
