Questions about WD Black SN850X

I have the model with 4tb and without heat sink. Mine is fitted on one side. If you have space for the heatsink, then go for the variant with heatsink, as the SSD gets hot under load.

It seems that there are a few issues with the detection of the WD Black SN850X SSDs. Here are some possible solutions: 1. driver check: make sure you have the latest drivers installed. Sometimes older drivers can cause problems. In your case, the device manager says that the drivers are up to date, but it might be helpful to check the drivers manually and update them if necessary. 2. WD Dashboard: There are reports that the WD Dashboard sometimes has problems recognising NVMe SSDs in Windows 11. Try updating the dashboard or using alternative tools such as CrystalDiskInfo to monitor the SSDs. 3. BIOS settings: Check the BIOS settings to make sure the M.2 slots are configured correctly. Sometimes resetting the BIOS settings to the default values can help. 4. recognition as HDD: If the SSDs are recognised as HDDs, this could indicate a problem with recognition by the operating system. Try to check the SSDs in the Device Manager and make sure that they are displayed under the NVMe controller. If these steps do not help, it may be helpful to look for more information in the forum or at Western Digital Support.

The WD_BLACK SN850X SSD is designed to handle intense gaming sessions with features like Adaptive Thermal Management, which helps manage heat generation. However, installing it as a second disk in a laptop may still pose thermal concerns, especially if the laptop's cooling system is not robust. It's advisable to ensure your laptop has adequate cooling capabilities to maintain optimal performance and prevent overheating.

So I didn't find anything with 4000GB at Galaxus. But how about this one? Kingston FURY Renegade with Heatsink (4000 GB, M.2 2280) In the questions about this product, someone has already written that he uses the 2TB version in the PS5. Greetings Mysti

Found out myself: I believe that the cashback is valid and have submitted my proof of purchase. However, WD's internal designation for this SSD is different, which means you first have to find out which one you have to select.

After consultation with our purchasing department, we cannot offer you a tested, suitable heatsink. A ready-made 4 TB bundle with heat sink is available from Seagate, for example.

According to https://psref.lenovo.com/Product/ThinkPad/ThinkPad_P17_Gen_2?MT=20YU, these ThinkPads only support M.2 2280 SSDs up to 2TB.

I can't find any information about this in official specifications, but according to test reports like https://www.tomshardware.com/reviews/wd-black-sn850x-ssd-review-back-in-black, the 4 TB version of the SN850X should also be single-sided.
