RAID 0 on SSDs - Write Back or Write Through?

Which is better for my setup (specs in sig)? Write Back or Write Through mode?

 

As with anything... use your system with your workflow for a week or so with one option enabled, then change to the other option and see if you notice anything obviously different.

(By the way; a post loses its meaning when it asks to refer to the sig (I have everything turned off because it slows my browsing times...). The reason it has no meaning? Because as soon as you update your spec's in that sig this question and possibly the answers will be useless to anyone searching for it in the future. Always make complete, self contained posts - at least that is what I try for).

 

Alright that makes sense, here are my specs:

Alienware 18 | i7 4810MQ @ 3.8 GHz | Dual Radeon R9 M290X Crossfire | 32 GB Kingston HyperX 1866 MHz RAM
2x Samsung 850 PRO 256GB SSD (RAID 0) + Samsung 840 EVO mSATA 1TB SSD | Windows 7 Professional

I am noticing my system snappier with Write Through I'll also run some benchmarks to check, thanks bro

 

Synthetic benchmarks don't mean much to me. I'm the benchmark.

Especially if the work gets done faster and even if the system is as snappy or snappier than the 'option' I am testing against, then it doesn't matter what the benchmark(s) might indicate - I'll use the faster option (for me).

 

That's weired. WT should write directly to the disk, so any calls to writes wait until the disk has completed. WB uses cache so the writes are buffered and then 'lazily' flushed by windows later to the disk so as far as the application is concerned the write should complete a lot quicker as it's to the buffer not the disk.
