As we enter day two of the Amazon Prime Day sales, the SSD deals continue to rain down. Savings and deals for 2025 mean that finally taking the leap beyond 1 or even 2TB of storage is now on the cards. 4TB SSDs at their best price should now run you in the region of just $0.05 per GB, or $0.06 if you want a more premium drive from the likes of Samsung.
Below, we list all the current 4TB and 8TB PCIe 4 and PCIe 5 SSDs we could find for sale, and we keep this list updated constantly. Many of these drives also make an appearance on our list of the Best SSDs, and you'll find plenty of other deals on smaller, more affordable SSDs in our Amazon Prime Day Best SSD deals 2025 hub.
Our new top drive, thanks to Amazon Prime Day, is the excellent Crucial P310, which is now $199 for a 4TB module, the absolute best SSD deal we've seen this week. The best mid-range drive on this list is either the Samsung 990 Evo Plus ($234) or the WD Black SN850X ($279).
You can peruse the list below and click on the bold blue price text in the table to see the deals:

If you can afford an 8TB drive, you'll be future-proofed for many years. However, 4TB is likely the sweet spot between price and capacity for most people. And of course, if you have more than one M.2 slot, you can always buy two 4TB drives for less than one 8TB drive.
