Related Questions and Answers

Q: 1. Will this heatsink fit inside a Asus zephyrus M16 laptop?

A: No, we do not recommend putting SSDs with heatsinks into laptops as they do not fit, and most laptops already have a thermal pad to support the heat of the M.2 drive. I would recommend getting the Samsung 2TB 990 PRO PCIe 4.0 x4 M.2 Internal SSD rather than the Samsung 2TB 990 PRO PCIe 4.0 x4 M.2 Internal SSD with Heatsink.

Q: 2. Is this a Class 40 device?

A: Unfortunately, Samsung has not disclosed what class the 4TB 990 PRO M.2 PCIe SSD falls under.

Q: 3. Will this 4TB 990 Pro with Heatsink fit in a Dell XPS 9530 1st or 2nd slot?

A: Dell has not published specs on the internal clearance available inside the XPS 9530, but in general drives with heatsinks such as the Samsung 4TB 990 PRO PCIe 4.0 x4 M.2 Internal SSD with Heatsink will not be able to fit inside laptops.

Q: 4. Can the heat sinks be removed? My Sonnet PCI card has its own heat sink that covers all blades.

A: The Samsung 1TB 990 PRO PCIe 4.0 x4 M.2 Internal SSD with Heatsink is not made to be removeable. If you do not need the heatsink, you should go for the "SSD Only" version, which does not come with a heatsink.

Q: 5. Will "Samsung 1TB 990 PRO PCIe 4.0 x4 M.2 Internal SSD" work well without a heatsink in an "Intel Vivid Canyon NUC 13 Pro"?

A: You can use a Samsung 1TB 990 PRO PCIe 4.0 x4 M.2 Internal SSD BH #SAMZV9P1TOB without a heat sink in any device that is designed to work with a NMVe M.2 2280 SSD.

Q: 6. Is this backward compatible to pcie 3 m.2 slots?

A: Yes, you can use the Samsung 4TB 990 PRO PCIe 4.0 x4 M.2 Internal SSD in a PCIe 3.0 M.2 slot at PCIe 3.0 speeds.

Q: 7. Isn't this ssd TLC? It's listed as MLC.

A: Yes, this Samsung 2TB 990 PRO PCIe 4.0 x4 M.2 Internal SSD is Samsung V-NAND 3-bit MLC. https://www.samsung.com/us/computing/memory-storage/solid-state-drives/990-pro-pcie-4-0-nvme-ssd-2tb-mz-v9p2t0b-am/#specs

Q: 8. How can I choose between the 980 and 990 for my NUC Extreme i9?

A: Both the Samsung 2TB 990 PRO PCIe 4.0 x4 M.2 Internal SSD and the 980 PRO are PCIe 4.0 SSDs; the 990 has a faster controller that's capable of achieving faster read and write speeds, so if you're looking for the fastest read and write speeds in your NUC, then I'd recommend the 990 PRO.

Q: 9. Will this work with (is it compatible with) the OWC Express 4M2?

A: Yes, the Samsung 2TB 990 PRO PCIe 4.0 x4 M.2 Internal SSD is compatible with the OWC Express 4M2, B&H # OWTB3EX4M2SL.

Q: 10. Does anyone have experience using one of these in an external enclosure? I'm interested in using it to backup footage in the field quickly.

A: If your computer is Thunderbolt 3 capable, the Samsung 2TB 990 PRO PCIe 4.0 x4 M.2 Internal SSD works well in the Sabrent Thunderbolt 3 to M.2 NVMe SSD Tool-Free Enclosure (B&H # SAECT3NS, https://bhpho.to/43jRAHO) for fast data transfers at Thunderbolt 3 speeds.
