Asked 1 year ago by DaniPadilla.

• A:Answer Yes it took me maybe 10 minutes to swap out. You may want to get some thermal tape, I just used the piece that was on the ssd in the device but I don't know if that's advisable or not. I have had no temperature issues my device typically stays right around 80c while playing intensive game on turbo plugged in.

Asked 3 years ago by Anthtex81.

• A:Answer You can get a good heatsink for less than $15 not sure it will fit your unit so check the ssd in the slot first if spacing looks good, add the heatsink. The ssd will work fine with or without the heatsink but your laptop will run cooler with it.

Q: QuestionIs the WD BLACK SN850X 4 TB internal SSD PCIe Gen 4 x4 NVMe compatible with my Dell XPS 15 9500?. I'm using now a 2TB SSD PCIe Gen 3 x4 NVMe, but I need more space, and I don't know if my laptop will recognize more than those 2 TB. Thanks

• A:Answer Do you have to check the specs if your computer has an additional spot for a second hard drive? It shouldn’t be a problem, but each computer is different. I’m not familiar with your model. Once you open it you can verify if you have the second spot it’ll definitely take it then you have to go into settings and initialize it.
