Crucial T710 4 TB M.2-2280 PCIe 5.0 X4 NVME Solid State Drive

Pros

• I doubt that you actually need 20 TB of storage, at least now. You can always add more drives later. PCIe 5.0 is not needed, but the T710 is cheap right now.
• The build has 64GB of ram and a super-fast 4TB PCIe 5.0 ssd, with DRAM cache. This SSD will excel in both small-file access and high bandwidth applications. It's more expensive than other 4TB disks, but is wicked fast.
• 4TB PCIe 5 NVME for project work
• Better spec 4TB PCie 5 NVME for $200 less - the 990 Pro is just too expensive.
• We have 128GB of ram and a super-fast 4TB PCIe 5.0 ssd with DRAM cache to keep small write speeds up.

Cons

• PCIe 5.0 drives are mostly a waste of money, especially for gaming.
