NVMe drives which are approaching RAM speeds are a good compromise if RAM and server components are outside of your financial reach.

- FractalNerve 9y ago@Zeusk is right, I wish costs of SSD-RAMs like Diablo Memory1 [1] were more affordable or transparent. Summary performance comparison by Storage Class: http://xitore.com/what-is-nvm-x http://xitore.com/what-is-nvm-x NVM-X RAM ≈ DDR4-3200 ↧Availability|↥Cost| ↥4TB@25,6 GB/s Diablo Memory1 ↥Availability|↥Cost|↱256GB@10GB/s EDIT, added source: [1] http://www.diablo-technologies.com/memory1/ http://www.diablo-technologies.com/memory1/
- pvg 9y agoFor a very generous definition of 'approaching'.
- dis-sys 9y agomany NVMe drives on the market are useless jokes. try some from the now biggest semiconductor company, test their fsync() performance and don't get a heart attack for seeing those ugly numbers. ;)

- dis-sys 9y agohi olavgg, I was searching for fast fsync & low cost NVMe SSD a few months ago, so I looked into consumer NVMe SSDs. Samsung 960 Pro was the first I tested, the results were just shockingly bad. It was so bad to the extent that I started to question whether my kernel/installation caused the slowness issue. Searched online and found a few of your posts talking about the exact same problem you saw. That saved me quite a bit time. :) Yes, totally agree with the conclusion in your link above, consumer SSD (NVMe or not, high end or cheap) doesn't worth a dime. Cheers!
