1. Twelve times the real speed
The SN850P reads up to 7,300MB/s, the 870 EVO caps at 560MB/s. Game loads, boots and big file copies finish on the WD before the Samsung has really started.
2. Samsung's own drive has a failure history
Certain 870 EVO 2TB batches have documented early failures and uncorrectable errors, a problem not turning up in SN850P reports. That is a manufacturing flaw, not a rumor, and it is the exact drive you are choosing between.
3. Cheaper and faster is not a hard call
The WD_BLACK is $424.99 against $499.47 for the Samsung, yet it delivers well over ten times the read speed. Paying more for the slower drive buys nothing but a worse number.
4. Built for PS5, not bolted onto one
The SN850P carries Sony's official PS5 license and a heatsink sized for the console's own storage slot. The 870 EVO is a laptop-era SATA drive with no such certification or thermal design for a console.
5. Yes, the Samsung fits more slots. Rarely the one that matters.
The 870 EVO's SATA interface still works in old laptops and desktops with no M.2 slot, which the SN850P cannot use. Unless you are upgrading a genuinely old machine, almost every PC sold in the last five years has M.2, so this is not most buyers.
