Optimizing cache for RAID 0 SSD

[Sunburn74]

Hi. I need assistance optimizing and unifying my dual SSD RAID 0 array. Below are the options that windows allows. I want to make sure that the options I select complement each other rather than antagonize each other





Which set of options maximizes data integrity?

Which set of options maximizes performance?

Which set of options do you recommend as the best of both worlds?

Thanks

Enable write cache buffer flushing, select write through cache (write back will be disabled) & if you click the help (bubble) option it'll explain the details of each mode. It (write through) also prevents data loss better than any other cache mode hence my pick.

Personally, even with a UPS, I've enabled write through on my SSD RAID0 array & tbh don't see much of a performance drop even as write back is supposedly faster. I guess with an SSD the difference is minimal, in your particular case you can test which suits you better by using CrystalDiskMark or any other diskbench utility.

Ok thanks. I did read those help bubbles but I still had a lot of questions.

Which set of options offers the most theoretical performance?

I actually believe I am favoring data integrity, but I want to make sure I have all the right options pointed in the right direction.

Write back is supposed to be the fastest of the three options available, it also has the highest chance of leading to data corruption. I tried it at first, even without a UPS, but didn't see much of a discernible performance benefit on my LITEON SSD array, as compared to write through.

Like I said earlier, in case of SSD's there'll be a minimal real world difference & whatever little there is you can check yourself using some of the benchmark utilities that we see in SSD reviews. That is the only way to know for sure, certainly as each setup is different.

Not touching it. You only even have options from Windows due to occasional legacy buggy software. With an SSD, cache mode settings are going to be minimal in their impact, if not downright negligible, as well.

Stripe size is the only meaningful performance option for mobo RAID 0/1/10, using an SSD, and 64KB (typically the default for Intel) tends to be a good, balanced, size.
