Best 4TB SSDs For PS5 If You Have A Massive Game Library

Why it wins: Samsung's 990 Pro is the gold standard for PS5 expansion. With sequential read speeds hitting 7,450 MB/s and write speeds at 6,900 MB/s, it obliterates Sony's minimum requirements. Games load nearly identically to the PS5's internal SSD—you won't notice any performance difference.

Real-world benefits: The 990 Pro uses Samsung's latest V-NAND technology and a powerful controller that maintains consistent speeds even when the drive is nearly full. This matters for those massive game libraries where you're constantly accessing different titles.

The catch: Premium performance comes at a premium price, typically around $280-$320 depending on sales. You'll also need to add a heatsink if you buy the non-heatsink version, though many retailers bundle them together now.

Best for: Enthusiasts who want absolute top-tier performance and don't mind paying for it.

Why it's great: Western Digital's SN850X hits the sweet spot between performance and value. With 7,300 MB/s reads and 6,600 MB/s writes, it's essentially neck-and-neck with the Samsung in real-world gaming scenarios. Most users won't perceive any difference.

Value proposition: Usually priced $30-50 less than the 990 Pro, the SN850X delivers 95% of the performance for 85% of the cost. It's available with or without a heatsink—the heatsink version is PS5-ready out of the box.

Reliability factor: WD's reputation for durability is well-earned. The SN850X comes with a 5-year warranty and is rated for 2,400 TBW (terabytes written), meaning it'll outlast your console's lifespan even with heavy use.

Best for: Smart shoppers who want flagship performance without the flagship tax.

Why it's interesting: The T700 is technically a PCIe Gen5 drive, meaning it's built for next-generation speeds (up to 12,400 MB/s). In the PS5's Gen4 slot, it runs at Gen4 speeds—but that future-proofing means excellent build quality and thermal management.

The PS5 angle: While you won't unlock its full potential in your console, the T700's robust controller and thermal design make it incredibly stable under sustained loads. If you ever move it to a PC with Gen5 support, you've got a beast on your hands.

Price consideration: At $320-$380, it's the priciest option here. You're paying for Gen5 capability you can't currently use on PS5, which makes it a tougher sell unless you value that future flexibility.

Best for: Users who split storage between PS5 and a high-end PC, or those who want the absolute best thermal performance.

Why it makes the list: The MP600 Pro LPX is purpose-built for PS5 expansion, with a slim heatsink designed specifically for Sony's tight expansion bay. At 7,100 MB/s read speeds, it clears Sony's requirements with room to spare.

The savings: Typically priced around $230-$270, it's often the most affordable 4TB option from a reputable brand. Corsair's gaming pedigree means they understand what gamers actually need versus marketing fluff.

Trade-offs: Write speeds are slightly lower at around 5,800 MB/s, but this only matters for content creators moving massive files around. For gaming? You won't notice. The heatsink is functional but not as robust as premium options, though it's perfectly adequate for PS5 use.

Best for: Budget-conscious gamers who want maximum capacity without overspending on specs they won't use.
