Enabling RAPID mode on Samsung 840 EVO SSD

Hello experts,

After reading this and other articles, I'm convinced to enable the RAPID mode on Samsung 840 EVO 250GB SSD:

RAPID Mode

Is there any reason why I should not? (The desktop don't have an UPS) :(

Any comments would be appreciated. Thanks in advance for your time.

If you wish to have the improved performance then enable the RAPID mode.
Read detailed info. in the attached "white Paper" from Samsung.Whitepaper-Samsung-SSD-Rapid-Mode-0.pdf

its neither here nor there cause you will not notice a significant difference in performance, ps its new technology wait until the kinks are truly worked out b4 advancing. it shows that it has failed one of the benchmark test, so I would be cautious.

Yes -- you gave the reason yourself:   "... The desktop don't have an UPS."

RAID controllers often use RAM caches onboard the controller to accelerate performance ... but they also have battery backups on those controllers.

RAPID is an internal cache which uses system memory for the cache ... so any power glitch or failure will instantly destroy the contents of the cache, and your SSD's contents will NOT match what the OS "thinks" has already been written to it.

If you want to use RAPID, add a UPS to the system FIRST.   FWIW, I think EVERY system should have a UPS anyway (all of mine do) -- power failures are probably the #1 cause of hardware failures; and with a UPS and automated shutdown software, a system is NEVER exposed to a power failure.

I do NOT, however, think you'll notice a significant performance difference by using RAPID.    Yes, you can show differences in benchmarks, but for most typical uses of a PC the SSD is going to be so fast that a few milliseconds of gain simply aren't something you'll actually notice.    But whether you do or don't choose to use it, get a UPS :-)

Thanks everyone.. Greatly appreciate the insights.

Looks like I'm ordering an UPS:
