What is the best SSD for a Dell XPS 15?

Question

I’m looking to upgrade the storage on my Dell XPS 15 because the stock drive is nearly full and feels a bit sluggish lately. I mostly use it for 4K video editing and some heavy multitasking, so I’m really looking for something with fast read/write speeds and solid reliability. I’ve been eyeing the Samsung 990 Pro or the WD Black SN850X, but I’m worried about heat management inside such a slim laptop. Does anyone have experience with which Gen4 drives run coolest in this chassis? I’m aiming for a 2TB capacity and have a budget of around $200. Which specific SSD would you recommend for the best balance of performance and thermals?

For your situation, I've actually done a few swaps in the XPS 15 chassis, and it definitely gets toasty in there during 4K renders! While the 990 Pro is a beast, it tends to run a bit hot for my liking in such a slim laptop. Honestly, I think the SK hynix Platinum P41 2TB PCIe NVMe Gen4 M.2 SSD is the secret winner here. It's incredibly power-efficient, which means less heat soak during long editing sessions, and it consistently hits those top-tier 7,000MB/s speeds.

Here are some solid, budget-friendly picks that won't thermal throttle as easily:

* SK hynix Platinum P41 2TB NVMe SSD - Usually around $150-$160, runs very cool.
* Crucial P5 Plus 2TB PCIe Gen4 3D NAND NVMe M.2 SSD - A great value option often found for under $130.
* WD_BLACK 2TB SN850X NVMe Internal Gaming SSD - Fast, but I'd suggest adding a thin copper shim if you go this route.

Personally, I'd grab the P41; it's the best balance of thermals and speed for under $200. Hope this helps!

Seconding the recommendation above! Thermal throttling is definitely a real concern in the XPS 15 chassis. Since these thin laptops lack airflow, you might want to consider the SK hynix Gold P31 2TB PCIe NVMe Gen3 SSD. Even though it's Gen3, it's famous for being the most power-efficient and coolest-running drive out there. For video editing, you won't notice a huge real-world difference compared to Gen4, but your laptop will stay much cooler. Good luck!

Seconding the recommendation above! Thermal throttling is definitely a real concern in the XPS 15 chassis. Since these thin laptops lack airflow, I've found that the SK hynix Gold P31 2TB PCIe NVMe Gen3 SSD is an absolute legend for efficiency.

However, if you really want those Gen4 speeds for 4K editing without breaking your $200 budget, check out the Lexar NM790 2TB NVMe PCIe Gen4x4 SSD. It's surprisingly cool because it doesn't use a dedicated DRAM chip, which usually draws more power/heat. Honestly, it's a great value pick over the 990 Pro for this specific laptop! Hope this helps!
