The WD Black SN850P is a bit of an odd device to review. We've already done thorough testing of the SN850 and SN850X, its two predecessors, and we didn't add the more recent "X" to our best SSD for gaming buying guides until recently. We saw a marginal increase in performance from the SN850, and we didn't deem the difference in price immediately worth it. The original SN850 still performs very well for a Gen 4 SSD, and part of me thinks the only reason we've seen two sequels to it in as many years is that SSDs are still in a sustained price slump.
The SN850 and SN850X are both available with and without pre-attached heatsinks, meaning they're versatile as PS5 SSDs, and SSDs for PC gamers. The SN850P, at the time of writing, is not available without the heatsink, and while it can be used in a gaming PC, there are plenty of motherboards that make life harder for people when heatsinks come pre-attached.
