RST vs. RSTe

[mccainm]

I was asked this question and didn't have an answer...and didn't find it via search. Intel releases two versions of its Rapid Storage Technology drivers...one of which is the enterprise version. What is the difference between the two and when would you select one over the other?

"The difference is that the RST is used for desktop systems and the RSTe is mostly used for server systems."
Here you go, and Id go for RST, why would you need enterprise edition?

Thanks for the link. The question for the enterprise edition came up because:
- A lot of Dell laptops come with their BIOS pre-configured in RAID Mode (not AHCI mode) even though they only have 1 x SSD.
- In RAID Mode most use the RST driver with the SATA/RAID Premium Controller (at least that is what it's called in recent versions).
- However, a lot of laptops now are coming with NVMe drives. If you look at the RSTe driver it lists controllers with NVMe and that is where the question came up.

I personally just converted my laptop from RAID Mode to AHCI and am using the Samsung NVMe controller driver and the AHCI SATA controller driver that comes with RST. RSTe curiosity because it specifically mentions NVMe in some controller driver titles. In RAID Mode, some might be curious to see if it enables better performance. I personally doubt it because I actually don't notice any performance difference (except for possible slightly quicker boot speed) between AHCI and RAID modes. However, there might be curiosity on whether there are different features between RST and RSTe.

In RAID performance gain is impossible if you dont get another hard drive, which you wont. Keep it in AHCI and install RST.
