  Is it suitable for the extra SSD for PS5?

    Officially, no, it is below specs.
    Unofficially, yes, it works.

    Since SN770 uses a WD custom controller, why didn't WD just beef it up a bit more? My guess is WD prefers you to buy SN850. Honestly though, that is technically unfair as no PCIe gen 4 x4 4 channel controller manages to reach PS5's recommended level (you need a decent 8 channel controller).

    One reviewer (NAS Compare I think) triggered the SLC to TLC recovery write phase due to repeated transfer tests. However, he didn't explain that in full, instead, pointed out that being an issue. Technically, unless you are reviewing SSDs for PS5 or you want to intentionally test that SSD in the worst case situation, you won't encounter that issue.

  Be sure to check your card.
  Their Black Friday sale showed discounted prices, but charged full.

  They always deliver, I've had success with them in the past, just the billing platfform seems to be iffy.

  have the 2T version of it as a game library driver, its a beast.

  Before anyone asks, yes this is better than the Kingston NV2 or Crucial P3 Plus, in top speed, HMB cache size (1/3 rather than 1/4 of free drive space), sustained speed, and durability ratings.

    SN770, while better than NV2 and P3 Plus, still has the same issue like most cost effective PCIe gen 4 x4 SSDs.

    • Its sustained write of 560MBps, while okay, is still at PCIe gen 3 SSD class level.
    • The full drive fill test of 1TB SN770 shows an average of 630MB/s compared to NV2 1TB (Phison E21)'s 619MB/s. So, that does mean, NV2, by not doing SLC recovery until after 80%, was able to bridge some of the gap in the middle part of the write. Furthermore, not seeing a full write test from Tom's Hardware means we do not know SN770's situation once the SSD is filled over 80% (at that point, for most SSDs, SLC cache cannot be used and any incomplete SLC cache recovery needs to take place right away). How did SN770 lose all that advantage to eventually only be 11MB/s better in a full SSD fill test?

    SN770 is a good SSD (especially in reads). However, I wouldn't hype up its sustained write. It's generally a better buy of the 3, unless you don't really care about performance that much and $85 NV2 1TB (when heavily discounted) is a good price to you as a toy. NV2 is a big gamble though (not recommended).

      Thanks for listing the caveats. People who are looking to buy should still do some research and prioritise features which are important to them (esp. for budget price points). For example, I keep my PCs for ~8 years on average so durability/warranty is much more important to me than top speed.

      It does seem that SN770, despite being marketed as a semi-premium drive ("WD Black"), is not particularly outstanding. Synthetic benchmarks aside, it seems unable to perform much better than the same as the clear tier-below product SN570 Blue in a significant proportion of "real life" benchmarks (Techpowerup).

        I tested a 2TB SN570 recently. The dynamic SLC cache (when the SSD is empty) is about 900GB. I am not sure whether the newer batch of SN570 1TB would be like that: 450GB SLC cache when empty (probably wishful thinking). SN770 is still faster in most cases, but in real life tests, probably not going to blow SN570 away.

        TBW, I don't care that much as all my SSDs which failed so far never even managed to write 10TB (one of them died with less than 1.5 TB TBW). NV2, to me is mostly a toy, more for experimental and portable / removable usage. I don't recommend it for mission critical use.
