The WD_SN850X 4TB is £208 on Amazon right now

The review

It's on Spring Sale for £208 directly by Amazon, lowest it has ever been according to Camel, with used - very good at £192.

1 of the top 3 DRAM Gen4 SSD, if you wanted to upgrade or just grab a new 4TB ssd, this is the cheapest I've seen a top 3 of gen4 this cheap. I'm waiting to upgrade myself but holding out for a 990 PRO price drop or maybe the T500. At £208 though, it's very tempting.
