If you want enough storage capacity to install all your favorite games, experiment with local AI or just have enough GBs free so you never have to worry about running out of space, 4TB is the ideal SSD size. Sure, 2TB is a lot cheaper in most cases, but 4TB is worth every penny if you can afford it.
Now, with Black Friday deals season upon us, you can get a 4TB SSD for as little as $0.05 per GB. As of now, the cheapest 4TB SSD we've seen is just $189 in the form of the Silicon Power UD90 and the good news is that, even for that price, you don't have to settle for poor performance. The UD90 itself is rated for 5,000 MB/s sequential reads, but we'd spend at least another $10 for the Silicon Power US75, which promises 7,000 MB/s reads for just $199.
| SSD | Best US Price | Price Per GB | PCIe Gen | Seq Read / Write | NAND |
|---|---|---|---|---|---|
| Silicon Power UD90 | $189 | $0.05 | 4 | 5,000 / 4,500 MB/s | TLC |

| Silicon Power US75 | $199 | $0.05 | 4 | 7,000 / 6,500 MB/s | TLC |
| Crucial P3 | $204 | $0.05 | 3 | 3,500 / 3,500 MB/s | QLC |
| TeamGroup MP44Q | $205 | $0.05 | 4 | 7,400 / 6,500 MB/s | QLC |
| TeamGroup MP44 | $226 | $0.06 | 4 | 7,400 / 6,900 MB/s | TLC |

| Kingston Fury Renegade | $254 | $0.06 | 4 | 7,300 / 7,300 MB/s | TLC |
| Samsung 990 Pro | $269 | $0.07 | 4 | 7,500 / 6,900 MB/s | TLC |
| Crucial T700 w/ Heatsink | $322 | $0.08 | 5 | 12,400 / 11,800 MB/s | TLC |
| Crucial T705 w/ Heatsink | $449 | $0.11 | 5 | 14,100 / 12,600 MB/s | TLC |
On the bright side, both Silicon Power drives use TLC NAND rather than the slower QLC NAND many budget drives employ. However, neither has a DRAM cache, which means that they can't sustain this performance for long.
The best 4TB combination of performance and value is the WD Black SN850X for $249. It's rated for 7,300 MB/s reads and boasts a sizable DDR4 DRAM cache. If you want a PCIe 5 drive, the best 4TB deal is on the Crucial T700 w/ heatsink, which is just $0.08 per GB and boasts read speeds up to 12,400 MB/s.
