Sandisk has put full specs and pricing on its Optimus GX PRO 850P PCIe 4.0 SSD line for PlayStation 5 and PlayStation 5 Pro, and the headline is hard to ignore: the 8TB model costs almost as much as five standard PS5 consoles in the US. The drive comes in 1TB, 2TB, 4TB and 8TB versions, but this is clearly a product aimed at enthusiasts with deep pockets, not the average player trying to save a few gigabytes.
That price tag sits in a familiar pattern for premium console storage. Sony’s own expansion guidance has long made room for third-party M.2 drives, but once capacities climb this high, the market starts looking less like consumer hardware and more like luxury kit for people who treat game installs like a collection hobby.
Optimus GX PRO 850P speed and endurance
Sandisk says the 1TB, 2TB and 4TB versions can read sequentially at up to 7300 MB/s and write at up to 6600 MB/s, although the 1TB model tops out at 6300 MB/s for writes. The 8TB version is slightly different on paper, with up to 7200 MB/s read speeds and 6600 MB/s writes, plus up to 1.2 million IOPS for random read and write operations.
Endurance scales with capacity, which is the part serious buyers will care about more than the marketing gloss. Sandisk lists 600 TBW for the 1TB model, 1200 TBW for 2TB, 2400 TBW for 4TB, and 4800 TBW for the 8TB drive, and all versions carry a five-year warranty. That’s the sort of spec sheet that says ”built to last” without needing to shout about it.
- 1TB: up to 7300 MB/s read, 6300 MB/s write, 600 TBW
- 2TB: up to 7300 MB/s read, 6600 MB/s write, 1200 TBW
- 4TB: up to 7300 MB/s read, 6600 MB/s write, 2400 TBW
- 8TB: up to 7200 MB/s read, 6600 MB/s write, 4800 TBW, up to 1.2 million IOPS
Sandisk PS5 SSD pricing starts at $379.99
The real shock is the sticker price. Sandisk lists the 8TB model at $2959.99 in its US store, and that is already a discounted price; the recommended price is $3699.99. The 1TB, 2TB and 4TB models are listed at $379.99, $759.99 and $1499.99, with recommended prices of $474.99, $949.99 and $1874.99.
- 1TB: $379.99, or $474.99 recommended
- 2TB: $759.99, or $949.99 recommended
- 4TB: $1499.99, or $1874.99 recommended
- 8TB: $2959.99, or $3699.99 recommended
For comparison, Sony raised PS5 pricing on 2 April. The standard version with a disc drive is now $649.99 in the US, the Digital Edition is $599.99, and the PS5 Pro costs $899.99. Against that backdrop, the 8TB Sandisk SSD looks less like an accessory and more like a price benchmark for how expensive console storage can get when capacity stops being a compromise.
The likely buyers here are the same people who routinely install massive backlogs, swap games constantly, and hate deleting anything. Everyone else will probably keep doing the sensible thing: buying a smaller drive, or waiting until high-capacity PCIe 4.0 storage stops charging supercar money for extra terabytes.
