Top box ticked.
Bottom box as it says in the description - on or off depending on whether or not you have battery backup (a laptop or a desktop with UPS)

a wash, though some ssd controllers may slightly benefit from it being checked. to see what it does, you might want to try it enabled, bench, then disabled, bench. in the old days, hdd/parity arrays could somewhat benefit from it, but for most these days, making sure the writeback is checked is all that is needed.

I think it depends from controller or cache options if is enabled RAID. If cache options are disabled in RAID BIOS then system cache should give some performance boost but if you already have write back or other option enabled in controller then better is to disable system cache. In AHCI enabling system cache should give better results.At least it works like that for me on 2x M4 in RAID0 and from time to time in AHCI.

if you disable caching, you disable performance. cache option should always be on, unless you like less performance. i have used both checked, and have noticed no improvement when the botttom box is checked (cache flushing). some drives using compression, or hdd arrays may get a boost from disabling flushing, but i don't.

It is years later and with the latest version of Crucial Storage Executive and Windows 2012 Server R2 without UPS and, I still get the confusing advices from either of the 2.
What is the advice really!?

I don't think the advice on this has ever changed?
Top box ticked (for performance)
bottom box unticked (for data safety)
