The final hours of Amazon Prime Day 2023 are winding down, and we're seeing epic deals on some storage begin to expire, so you'll need to act if you want to score a deal on some of the best SSDs and best hard drives. Where the price of a 4TB drive was out of range for many folks before, today you can grab a decent drive for less than $200 or a top performer for just a little more than that. The best SSD for PS5 and one of the fastest SSDs you can buy for PC, the WD Black SN850X is now just $229, an all-time low (down from $299).

If you're after the best capacity per dollar, the crown belongs to TeamGroup's MP34 for just $156. It's a PCIe 3.0 SSD with 3,500 MB/s and 2,900 MB/s speeds. That's a fast enough speed for many boot drives and more than adequate for your D drive. We're covering all the savings on our best Prime Day SSD deals page, but below, we've listed the top 4TB bargains.


WD Black SN850X 4TB: was $699, now $299 at Newegg

WD Black SN850X 4TB: was $699, now $299 at Newegg
The SN850X is a speedy PCIe 4.0 SSD for PCs, laptops, and the PlayStation 5. The drive boasts a sequential performance that peaks at 7,300 MB/s reads and 6,600 MB/s writes. See our review of the WD Black SN850X for more information. The drive is on backorder, but still available for now at this pricing. 

Price Match:  Best Buy $299

This drive has been one of the hottest buys of Prime Day, so it is currently on backorder at Newegg and out of stock on Amazon, but you can still get it at this price while supplies last at Newegg. The SN850X boasts sequential read and write speeds of 7,300 MB/s and 6,600 MB/s, respectively. The PCIe 4.0 SSD's random performance is very respectable, too, boasting 1,200,000 IOPS reads and 1,100,000 IOPS writes. When we tested the 2TB capacity, which is now just $99, we found it just a notch behind the much more expensive Samsung 990 Pro.

Although the SN850X doesn't sport the PlayStation 5 badge, it's still one of the best SSDs for the PlayStation 5 and substantially cheaper than the PS5-licensed WD Black SN850P. The only drawback with the SN850X 4TB that's on sale is that it doesn't come with a heatsink. However, you can buy a third-party heatsink for around $10 on Amazon.

The SN850X 4TB has great endurance, proudly sporting a rating of up to 2,400 TBW. It also enjoys a lengthy five-year warranty.

TeamGroup MP34 4TB:  was $206, now $159 at Amazon

TeamGroup MP34 4TB: was $206, now $159 at Amazon
The MP34 is a PCIe 3.0 x4 SSD but still delivers respectable performance at 3,500 MB/s sequential reads and 2,900 MB/s sequential writes. See our review of the TeamGroup MP34 for more information.

The TeamGroup MP34 4TB is now going for just $159, and though it may be outdated, it continues to be a strong performer. The Phison E12-powered drive currently tops the list as the most affordable 4TB SSD at just 4 cents per GB. The MP34 is an M.2 2280 drive that sticks to an older PCIe 3.0 x4 interface, but don't let that get to you. The SSD is still leagues above your average hard drive or SATA drive. 

With sequential read and write speeds of 3,500 MB/s and 2,900 MB/s, respectively, the MP34 4TB functions as an excellent primary storage drive. One of the MP34's strong points is the drive's endurance. The SSD has a rating of 2,400 TBW and is backed by a five-year warranty.

Price Match: Amazon $179.99

On the other hand, the MSI Spatium M461 4TB is a slightly more expensive option for consumers that want firepower and ample storage in the same package. The SSD, powered by the Phison E21T controller, currently sits at  4.5 cents per GB or as low as 4.2 cents depending on your retailer of choice. The M.2 2280 drive leverages the faster PCIe 4.0 x4 interface to hit sequential read and write speeds up to 5,000 MB/s and 4,200 MB/s, respectively.

The Spatium M461 isn't nearly as durable as the MP34, though. MSI rates the drive for 900 TBW, but it shouldn't be an issue if you're employing it as your primary SSD with normal usage. The Spatium M461 is protected with a five-year warranty or until the TBW is up.

    I just bought a 2tb P31 for $94.40. For laptops that are limited to gen 3, nothing better out there (Power efficiency coupled with speed).

    As these 4TB enter sub $140 territory it is going to be mighty hard to resist.

    If you have a PS5, the Samsung 980 Pro with a built in heatsink is $99. That's a good deal. I would just make sure you update firmware on the drive via your PC before installing it on the PS5.

    Couldn't resist.... upgrading storage on my office machine. Just bought a pair of the SN850X 4TB for about $229 each. Totally ridiculous price.
