970 vs 980 Nvme: Check Compatibility and Speed
Match the drive to your system before buying: compare interface, capacity, and rated speeds in 970 vs 980 nvme for November 2026.

An M.2 slot doesn’t automatically mean your computer supports every NVMe drive, and that distinction can make a promising upgrade a poor fit. 970 Vs 980 Nvme puts a PCIe Gen 3 option beside a PCIe Gen 5 option, but interface support and your workload matter as much as headline speed. The Samsung 970 EVO Plus SSD 500GB lists PCIe Gen 3.0 x4, while the XPG 1TB Mars 980 Blade PCIe 5.0 NVMe M.2 2280 lists PCIe Gen 5 x4. Check your motherboard or laptop manual before buying, and see this guide to M.2 form factor and NVMe compatibility if those terms are easy to mix up.
The Samsung lists manufacturer-rated sequential speeds up to 3,500MB/s read and 3,300MB/s write, plus a 500GB capacity, a five-year limited warranty or 600 TBW, and Samsung Magician software. XPG lists up to 14,000MB/s read and 12,000MB/s write for its 1TB drive, with onboard DRAM and thermal-throttling protection; advertised peaks depend on the host system and workload. That makes the choice less about one spec winning and more about usable capacity, supported PCIe generation, and the tasks you actually run. For gaming, project files, or routine computing, weigh system fit and value alongside the figures rather than assuming a newer interface guarantees a noticeable improvement.

Questions Before You Buy
Will either drive work in my laptop or desktop?
Check your system manual before ordering; the supplied details don’t confirm compatibility with a particular motherboard or laptop. Match the M.2 form factor and NVMe support, then verify the PCIe generation and available clearance for the selected drive.
Does PCIe Gen 5 make the XPG the better buy?
No, not automatically; the XPG lists PCIe Gen 5 x4, while Samsung lists PCIe Gen 3.0 x4. The host system must support the interface, and advertised sequential read and write speeds are not guaranteed in every workload.
Which drive offers more room for games and files?
The XPG model listed here has 1TB capacity, compared with 500GB for the Samsung. That extra space can suit larger game libraries or project files, but confirm your available M.2 slot and storage needs before choosing.
Do the supplied details establish warranty and endurance?
The Samsung listing specifies a five-year limited warranty or 600 TBW; the supplied XPG details don’t state a warranty duration or TBW rating. Review each manufacturer’s current terms before purchase, especially for a sustained workload.
Should I plan for a heatsink or migration software?
The Samsung details mention Magician software and Dynamic Thermal Guard, while the XPG details cite thermal-throttling protection; neither supplied listing confirms an included heatsink. Check laptop clearance, motherboard cooling, and operating-system migration needs before installing an SSD.
