Crucial 4TB SSD: https://www.amazon.com/dp/B0B25P44CL?psc=1&ref=ppx_yo2ov_dt_b_product_details

The SSD is actually a really good deal right now; when I bought it at the beginning of February it was $249 (which was still a good deal compared to other 4TB SSD options), and now it's $219.

Tempted to buy the 4tb would this be good to replace a 2tb spinner?

Edit ~ Would this be better?

I searched the Crucial product pages for the P3 and P3 Plus

https://www.crucial.com/ssd/p3-plus/CT4000P3PSSD8

as well as the Amazon product pages

https://www.amazon.com/Crucial-Plus-PCIe-NAND-5000MB/dp/B0B25M8FXX

and could find no reference to "HMB" at all on the product page, in the Q&A, and in the user reviews. On Amazon, there were 6 times in the P3 Plus Q&A, when people asked about DRAM, that a Micron rep answered that there is no DRAM but he failed to mention anything about HMB (which would have been a plus). Maybe the P3 and P3 Plus had HMB at one time but the status seems to be secret now.

If you want one even smaller, you can put a 4TB NVME in an enclosure. But if you're constantly writing to it, I would only use it with a fan blowing right on it. They tend to throttle when overheated.

A quality NVMe enclosure and your own drive.

Or spend half as much on spinning rust that's 50X slower and guaranteed to fail immediately if you drop it or naturally in three years.
