April 7, 201610 yr Hello! I have just setup an unRAID server and I was getting mediocre write performance, around 60MB/s over SMB shares. This is with 7200RPM drives including parity. In order to speed things up, I purchased a 480GB SSD and set that up as the cache drive. I then went into the share that was created previously, and enabled the cache drive. When writing to the share, I can see that the cache drive is being used. However, the only increase in speed I am seeing is from not needing to spin up. The actual transfer is very similar at about 65MB/s. The network is running 1gb eth and unRAID is showing full duplex 1gbps link. I then tried setting up a cache only share just to be sure it was not still writing to the HDDs, and the speeds were the same, about 65MB/s I am a sysadmin, so all the basics should be covered but feel free to chime in on basic things I may have missed. I have three ESXi hosts on the same switch and they are getting the expected speeds. To test the transfer speeds for unRAID all ESXi hosts were powered down. Any advice or direction to go would be appreciated. https://www.reddit.com/r/unRAID/comments/4ds1yo/cache_drive_did_not_improve_write_performance/ Thanks
