Whether you play a lot of PC games, work with lots of photos and videos or experiment with running local AI models, you need at least 4TB of SSD storage. Welcome to October Prime Day 2024 where we are seeing huge deals on some of our favorite 4TB SSDs, with prices as low as 5 cents per GB.  We have at least 6 drives hitting this price point, including the fantasticCrucial P3 Plus 4TB which is on sale for just $199.

Due to increases in the cost of Flash memory this year, these deals are not quite hitting the all-time lows we saw last fall or even some we saw in July, but we are seeing good discounts on many of our favorite large-capacity 4TB SSDs such as the blisteringly fast4TB Samsung 990 Pro (with heatsink) for $265, and the equally speedy4TB WD_Black SN850X for just $264. Both these drives work out at roughly 7 cents per GB, which is still great value for the fastest PCIe Gen 4 drives on the market. The 990 Pro is the lowest price we’ve ever seen it for, with a heatsink (it is also $10 cheaper right now than buying it without a heatsink).
