What is ahci and raid

There are several more configurations defined that either improves performance, reliability or both. In terms of features, it basically exposes the same feature set that is available in AHCI making them identical in single disk applications.

RAID truly shines when you go into multi disk configurations where you can utilize its more advanced features because AHCI is unable to operate in this mode. But using RAID can become very expensive once you start adding more disks into your array.

For what it's worth I found that I had the Intel Optane software installed on my by default even though I didn't have an Optane drive. Even that doesn't offer much functionality when running a single SSD, but again I suspect this is a case of factory standardization even in situations where the result is not a ideal for individual cases as it could be.

NyarehD When I tested the two modes back to back on an XPS 13 running a Samsung Evo a while ago, the differences seemed to be within the margin for normal variation or thermal adjustments by the SSD.

Answer: The following post contains Dell M. Dell Support is also on Twitter! It appears that only software based security is available for most or all NVME drives on a dell system, which does slow down the system, increases the power consumption, and is not as good as hardware security.

I personally am not in the loop on future developments. I'm mainly here to support what's already released. I wouldn't have the answer due to this scope of support limit. Interesting points about the power consumption. Justin, thank you for a very informative post which clears some confusion regarding SSDs and configurations in Dell systems. I'd like to ask you something specific to mine. I've seen your post regarding other systems but excluding Inspirons.

If this is not appropriate place for asking such question please let me know if I should create separate thread as I'm new to the forum. This system promises exactly that and so far it delivers smoothly and mostly silently. However in my country lower end models were not available with an IPS display TN only hence I went with very pricey top configuration which is here approaching the price tag of XPS systems but on a side note has gorgeous display and solid NVMe drive. I bought it intending to expand RAM and disk storage.

Now that I'm trying to find anything related to this I keep stumbling upon conversations where attempts to install this drive ranging from impossible to a solutions involving BIOS settings and changing AHCI to RAID losing ability to use Samsung Magician software and drivers and claims that it's no supported by Dell. Even clams that in case of NVMEe drive it's impossible to add any other as literally whole bandwidth is consumed?! But those were mainly related to lower spec models sporting regular m.

What are preferred BIOS settings to make this kind of setup hopefully working and will I need any extra parts to install it properly? Do you have any other recommendation to avoid troubles. There were some discussions mentioning incompatibility issues with Samsung SSD drives but again those were related to primary NVMe drives which I have no intention to touch.

Another question is related to Windows driver. Currently native one is installed. Do you recommend using retail Toshiba drivers instead or is this discouraged on OEM drive. I can only support what Dell sells with systems from the factory. I went back into our parts list and found out that the 2. I didn't find a shim for 6.
