There are 8TB drives, and (ignoring QLC ones) 18 months ago you’d have paid over $1200 for either of the two models available (Sabrent Rocket 4 Plus or Inland Performance Plus). Then WD released a 8TB version of their SN850X at an initial price of $850. These days I regularly see it for $650 or below (Amazon actually has it for $600 right this moment), which is a positive but tolerable premium over buying 2×4TB of the same (admittedly high-end) model. The other two options have also come down in price, though the Sabrent still hovers just below a thousand.

Be extremely careful of buying WD (NVMe) SSDs if you're intending on using them with Linux: https://github.com/openzfs/zfs/discussions/14793 https://github.com/openzfs/zfs/discussions/14793 Many _serious_ reports of problems there, across many models and firmware revisions. It's an ongoing problem, and WD is ignoring it entirely.

  It's just a brand. The SN770 shares nothing technical with, for example, the SN8100.

    Well, "the brand" is ignoring the problems across several SSD models.

      The reports in that thread you linked to are clustered around several models that do have substantial shared technology: a DRAMless design using an in-house SanDisk controller, and difficulties arise with the NVMe Host Memory Buffer feature that is only applicable to DRAMless drives. But the high-end SanDisk drives aren't DRAMless, and the SN8100 in particular doesn't even use an in-house SanDisk controller.

  Thanks! I see that the people reporting problems with the (DRAMless) SN770 there also report no problems with the SN850X, but that might not be indicative either way—AFAIU the 8TB SN850X has somewhat different internals compared to its lower-capacity brethren. (It does put Framework’s decision to ship SN770—now SN7100—SSDs in their laptops as standard in an unfavourable light.)
