Which is better for gaming?

The SN770. Its higher write speed and 800K random write IOPS cut game install and patch times, and the 5-year warranty covers years of use. The SN3000 will still load games fine, just slower on writes.

The SN770, rated at 1,200 TBW with a 5-year warranty. WD does not publish an endurance figure for the SN3000, and the Green line sits below Black, so treat it as the shorter-lived drive under heavy writes.

Is the SN770 worth the extra money?

If you game or write large files regularly, yes. If the drive only holds media and documents, the SN3000 saves money and the read-speed gap is small.

Will either fit a laptop or PS5?

Both are M.2 2280 and single-sided, so they fit most laptops and the PS5 slot. The SN3000 runs cooler and draws less power, which matters more in a laptop.

Do either have DRAM cache?

No. Both are DRAM-less and rely on nCache 4.0 and host memory buffer. That is why sustained writes drop on large transfers.

Which is better for video editing?

The SN770, for its higher sustained write speed and endurance. For 4K timelines, either works as a scratch drive, but the SN770 handles longer writes before slowing.

WD_Black SN770 NVMe SSD vs WD Green SN3000 2TB NVMe SSD

Both are 2TB PCIe Gen4 drives with similar sequential speeds, so the real split is workload and endurance. The WD_Black SN770 is the gaming drive: higher rated write speed, much higher random write IOPS, and a 5-year limited warranty. The WD Green SN3000 is a budget drive with no DRAM and lower endurance, aimed at everyday storage and laptop upgrades.
