The questions that come up before an order
Why does it cost so much more?
On October 26, 2026 it was $281.50 against $168.99 to $188.95 for the other Gen 4 drives with an offer. Its page states a warranty and a random write figure; it does not state faster sequential speeds than they do.
Does it work in a PCIe 3.0 slot?
Yes, the third bullet says it is compatible with PCIe 4.0 and 3.0, at the slower generation's speed.
Our score
8.4/ 10
The most completely specified drive on this shelf for speed and warranty, and the most expensive by a wide margin on this date. The KingSpec XG7000 states a warranty too, with an endurance figure, for $112.51 less.
