Low speed mainly reading but also writing for WD Blue SN570 500GB SSD (PCIe 3.0) and Kingston SSD FURY Renegade SSD, M.2 - 500GB (PCIe 4.0) in CrystalDiskMark SEQ Q8T1 test in NUC 11 Essential Kit - NUC11ATKPE with Windows 10 64. After installing Windows 10 64 bit downloaded and successfully installed all drivers, downloaded updates for Windows. The Intel® Rapid Storage Technology Driver is not available for download for the NUC11ATKPE on the INTEL website. This driver can only be downloaded for NUC in higher versions with Intel processors from i3 upwards. Does the absence of the Intel® Rapid Storage Technology Driver affect the speed of the SSD in the NUC 11 Essential Kit - NUC11ATKPE? The speed of the two SSDs mentioned above was tested in the CrystalDiskMark application. The reading speed result in CrystalDiskMark SEQ Q8T1 is similar for both disks, maximum approx. 1680 MB / s. I also searched in the UEFI settings options, I think everything is set up correctly. Where else can I make changes to the settings to increase the SSD speed? SSD PCIe 4.0 Kingston SSD FURY Renegade M.2 - 500 I bought additionally. If the problem persists, I am considering NUC NUC11ATKPE and WD Blue SN570 500GB PCIe 3.0 to return and buy NUC with Intel i3. There is already PCIe 4.0 support and I will install the Kingston SSD FURY Renegade M.2 - 500GB SSD. Does anyone have experience with NUC NUC11ATKPE? Does anyone have a higher read speed from the SSD than 1650 MB / s in CrystalDiskMark, item SEQ Q8T1. Thank you for the advice. Zdeněk Kollmann, Czech Republic, email: <removed>
For starters, there is absolutely zero performance advantage to having the Intel RST package installed. Unless you are using an Optane Module/SSD or are using RAID, you do not need - and seriously, you do not want - Intel RST enabled/installed. Same goes for the NVMe drivers from 3rd parties; they are only going to help with support of apps that they also provide - sometimes at the expense of compatibility for other apps. The 3rd-party drivers are not going to make a difference to performance.
Next, let's discuss the NUC in question. It AT NUCs have an M.2 Type-M 2280 connector - but this is only a x2 capability, not x4. Performance is going to be roughly half of what Gen3 drives can possibly do. For your Gen3 SN570 3500/2300 drive, which I would (thus) expect to see doing 1750/1150, if it is actually doing 1680/1575, that's not too bad.
If this level of performance is not good enough, you can move up to the Core i3 PA or TN NUC (i.e., NUC11PAi3 or NUC11TNi3). They do indeed offer a Gen4 x4 M.2 Type-M connector.
Hope this helps,
