Here is rapid mode off and then on, but the numbers... that's what's really confusing me..

That "Rapid Mode" is using a portion of your 16GB desktop ram to boost speed. Be more careful with sudden shutdowns.

being relevant: what is rapid mode, and should i bother with it? my OS SSD (850 evo) seems to support it.

you know aussie man I have it turned on and WOW what a freaking snappy bugger she is!

well it certainly boosts the benchmark in the tool itself.

Pity its on my OS drive and not my games drive.

Pfft I only have the 250GB drive and I have a game on it... Yes I have an 80gb game on it just for the speed :fear:

I know I need to get out more and get more GB but hey.. :rockout:

Seems to work dam good for me on GOW4 especially after the enable.

Perfect to the point that about 6 yrs ago @erocker asked me about if I'm using an APC unit to have the steady power line wave to my AMD 6 core chip...

Actually, that's not entirely true. The read portion is cached read data cached in advance by Samsung's algorithm so if that's gone, no biggie. As for write, it just acts as a write through buffer, meaning you'd lose data either way for two reasons:

- If data is written fast into system memory and then flushed to NAND while system loses power, you'll probably lose that data in RAM.
- If data tries to get written directly to NAND chips, but never gets the chance to get written down to the very end due to power loss, you'll also lose data, because it never reached the destination, either write buffer or the NAND chips.

The thing is, all drives are designed to use system memory as write through cache. Write through means OS waits for a specific amount of data to be written into write buffer or for it to stay in it for a specified period. Once both or either conditions are met, it flushes the cache to a storage drive.

If you really want to avoid data loss, you also have to disable write caching for each drive under Device Manager. But you'll be still facing a second point failure scenario as described above. Only absolute way to prevent that is UPS unit. Even the most basic one that can keep your system operating for at least I don't know, 5 minutes, so you can save stuff and shut it down.

I've had several system lockups and power loss scenarios and so far I never had anything corrupted or missing even with RAPID Mode enabled.

What part of what was stated, in the link, is contestable?

RejZoR · Dec 2, 2016

I was just stating data loss is not a fault result of Samsung's RAPID Mode, but of how storage devices work as a whole.

Thank you for clarifying.

Did they hide or get rid of the "Performance Optimization"? It's about the only thing I ever used.

Best,

Liquid Cool

The performance optimization for my 840 EVO 1TB used to take a couple seconds on 4.9.7, but it's now ~10 minutes and it is only 75% done with 5.0. So either it did not actually do anyting in the previous versions, or the current one is full of sh*t.
