Eeeek... OCZ SandForce drive using to show "enterprise" power loss protection.

The bad/ sad part of using that example is that SandForce actually did not use DRAM as a write buffer. So in essence, the capacitors he is showing are not actually doing what the article describes.

Not surprised cheap consumer drives causing issues. Would have been interesting at least if they used some decent Intel or Samsung consumer SSD's.

Closest SSD with these specs is the Samsung 850 evo (98k/90k, 150twb, 5 year warranty).

TLC NAND. Absolutely shouldn't be used. The 1TB 850 EVO has a write endurance of a whopping 0.08 drive writes per day over 5 years. It has probably the weakest NAND of any SSD on the market.

They link to a disk benchmark tool for Windows that I didn't knew about and it bypasses the cache and show us the true write iops! I hope this can mean death to the horrible consumer drives which build they reputation by lying to us.

looks like i have a new benchmark to play with... and yes TLC nand should be avoided for what they're doing, even if samsung has some of the best TLC with their 3dnand it's still second to MLC for enduance(sidenote a mushkin MLC drive I was testing appears to have better enduance than the 850 evo i've had in my system for over a year)
