4TB SSD Deals Start at Just $199 for World Backup Day

Nearly five years ago I wrote a story proclaiming I’d never buy a hard drive again. And every year since, that promise is easier to maintain because flash-based storage just keeps getting cheaper. If I didn’t already have several 2TB SSDs (yes, I have a storage problem), I’d be sorely tempted to pick up one of the 4TB options below, many at their lowest prices ever. 

If you're still stuck on SATA, Crucial's 4TB MX 500 is down to just $225 (don't forget to clip the coupon). Don’t expect extreme speed from this drive. But if you don't have any spare M.2 slots on your board, it’s hard to complain about paying less than six cents per gigabyte. And the endurance on the Crucial drive is rated at 1,000TBW.

If you prefer storage on the other end of the speed spectrum, WD Black's excellent  PCIe 4.0 4TB SN850X is down to an amazing $299. Long at or near the top of our Best SSD list, and our current top pick for Best SSDs for the PS5, the SN850X is a stunning performer that only gets more appealing as its price continues to hit new lows. I bought a 2TB SN850X myself for a new build a couple of months ago, and now I wish I'd held off for the roomier 4TB variant considering it's selling today for about 7.5 cents per gigabyte at this top capacity.

If you don't have a spare PCIe 4.0 slot, TeamGroup’s 4TB MP34 M.2 PCIe 3.0 SSD is selling for just $199, which is all the more crazy when you realize this mid-range PCIe 3.0 drive was selling for nearly $500 a year ago. With 3,500/2,900 MB/s rated sequential reads and writes, it would do quite well as a cavernous boot drive or fast secondary storage. It’s also rated to an astounding 2,400TBW of endurance and comes with a 5-year warranty. 

Not sure about putting 4TB of your precious data in the hands of TeamGroup? Crucial's 4TB PCIe 3.0 P3 SSD is also on sale for just $199. This is a QLC, DRAM-less drive, so general performance and endurance aren't as good as pricier drives (though you still get a rating of 800TBW and a five-year warranty), and again, at five cents per gigabyte, this is a lot of drive for very little money. If you're after a secondary game drive, to store all the titles you might play someday, this is a good option at a great price. 

4TB Crucial MX500 2.5-inch SATA SSD: now $225 at Amazon (was $359)
The MX500 has been around since 2017, but this TLC drive is a dependable workhorse that would be great as a secondary storage or game drive. Its 560/510mb/s sequential read/write rating is pretty close to the limit of SATA performance.

4TB WD_Black SN850X NVMe M.2 PCIe 4.0: now $299 at Amazon (was $499)
The WD_Black SN850X is our current top pick for our list of Best SSDs for the PS5, but it is equally adept in a desktop PC. The drive is now on sale for $299, which is an excellent deal given its impressive performance rating of up to 7,300 / 6,600 MBps of read/write throughput.

4TB TeamGroup MP34 M.2 PCIe 3.0 SSD: now $199 at Amazon
When we reviewed the MP34 back in 2019, it was an excellent value, offering solid performance (it’s rated to 3,500/2,900 MB/s sequential reads/writes) and high endurance at competitive pricing. Here in 2023, the 4TB model is down to an astonishing $199. A year ago, it would have been a good deal at twice that price.

4TB Crucial P3 M.2 PCIe 3.0 SSD: now $199 at Amazon
Crucial’s P3 Plus isn’t the best-performing drive by any measure, but it’s to at up to 3,500 MB/s sequential reads and 3,500 writes, with a good 5-year warranty. At its lowest price yet of $199 for the 4TB model, it’s hard to argue against.

4TB Crucial X6 Portable SSD: now $218 at Amazon
If you want to bring your 4TB of SSD storage with you, you won't likely find anything more affordable than the X6 external SSD from Crucial. It's not fast by SSD standards, but with rated speeds of 800MB/s and no moving parts, it's definitely faster and more durable than a hard drive.
