Key Takeaways
- SanDisk’s officially licensed 8TB Optimus GX Pro 850P launched on June 16, 2026 at a “discounted” $2,959.99, down from a $3,699.99 list price.
- That single drive costs more than three PS5 Pro consoles, which sell for $899.99 each after Sony’s April price increase and already ship with a 2TB SSD inside.
- The drive is a PCIe 4.0 model rated at roughly 7,200 MB/s reads and 6,600 MB/s writes, with an 8TB endurance of 4,800 TBW and a five-year warranty.
- Its specs are nearly identical to the older WD Black SN850X, which sold for around $600 in 8TB form before prices spiked.
- A worldwide shortage of NAND flash and DRAM is the root cause, the same memory crunch that powered the AI data-center boom and the 2026 chip-stock rally.
- For most players a 4TB drive is plenty; the 8TB model is a niche purchase for collectors and content creators who want maximum space and official branding.

SanDisk’s new 8TB PS5 SSD costs almost $3,000, more than three times the price of a PlayStation 5 Pro. The Optimus GX Pro 850P, an officially licensed drive aimed at the PS5 and PS5 Pro, went on sale on June 16, 2026 with the 8TB version listed at $2,959.99 – and SanDisk presents even that figure as a launch discount off a $3,699.99 sticker price.
The short answer to why it costs so much is not the storage itself but the raw memory inside it. A global shortage of NAND flash and DRAM has pushed component prices up across the board in 2026, and SanDisk is passing those costs straight to buyers. The drive’s performance is ordinary for a high-end PS5 SSD; the price is the only thing about it that breaks records.
How the 8TB PS5 SSD Price Compares to the Console
Sony raised hardware prices on April 2, 2026, setting the standard PS5 at $649.99, the Digital Edition at $599.99, and the PS5 Pro at $899.99 in the United States. Against that backdrop, a $2,959.99 storage stick costs more than three PS5 Pro consoles combined. The PS5 Pro is the relevant comparison because it already ships with a 2TB SSD built in, so a buyer is paying triple the console price purely to add external capacity. Even the smaller 760-dollar 2TB Optimus model (reduced from $950) lands above the price of a full standard PS5 with a disc drive.
| Hardware | US price (June 2026) | What you get |
|---|---|---|
| PS5 Pro console | $899.99 | Console plus a built-in 2TB SSD |
| Standard PS5 (disc) | $649.99 | Full console, 825GB internal |
| SanDisk Optimus GX Pro 850P 8TB | $2,959.99 (from $3,699.99) | One storage drive, no console |
| SanDisk Optimus GX Pro 850P 2TB | $760 (from $950) | One storage drive, no console |
What the SanDisk Optimus GX Pro 850P Actually Offers
The Optimus GX Pro 850P is a rebrand of SanDisk’s previous WD Black line, which moved under the SanDisk name after the SSD division split off from Western Digital. It comes in 1TB, 2TB, 4TB, and 8TB capacities, all built on the M.2 2280 form factor with a heatsink shaped for the PS5’s expansion slot. It is a PCIe 4.0 drive, not the newer PCIe 5.0 standard, which is fine because the PS5 does not support Gen 5 speeds anyway.
On paper the 8TB model reads at up to 7,200 MB/s and writes at up to 6,600 MB/s, lists up to 1.2 million random read and write IOPS, carries 4,800 TBW of endurance, and comes with a five-year limited warranty. SanDisk says the largest model holds roughly 200 games. Those numbers sit comfortably above Sony’s 5,500 MB/s minimum, but they are not meaningfully different from drives that have been on shelves for years. The drive that the 850P replaces, the WD Black SN850X, posts almost identical figures and once sold for under $600 in 8TB form during sales. Digital Foundry noted that discounting the new model back to that level would amount to an 84% cut – a sign of how far the price has detached from the hardware.
Why Memory Prices Pushed Console Storage So High
The reason a familiar drive suddenly costs five figures’ worth of attention is a supply squeeze in memory chips. Through 2026, NAND flash and DRAM ran short as AI data centers absorbed enormous volumes of high-bandwidth memory, and the scarcity rippled out to consumer products including phones, PC components, and game-console storage. The same pressure that lifted memory makers’ margins to record levels is the reason a gamer now pays a premium for capacity. The dynamics behind that crunch are the subject of how high-bandwidth memory became the AI hardware bottleneck, where suppliers like Micron and SK Hynix sold out their entire 2026 output.
SanDisk is not alone in raising prices. Sony lifted console and PS Portal prices in April, Microsoft increased Xbox prices twice in 2025, and Nintendo raised the Switch 2 by $50. Apple’s chief executive publicly described component costs as unsustainable. The console-storage market is simply one of the most visible places where the squeeze shows up, because a single drive’s price now towers over the machine it plugs into. The broader story of AI’s appetite for hardware – and the energy and chips that feed it – runs through AI’s enormous demand for electrical power and the NVIDIA Blackwell systems driving data-center memory demand.
Should You Buy the 8TB Model?
For nearly every PS5 owner, the answer is no. A 4TB drive holds the vast majority of a typical library, and reaching the ceiling on 4TB takes deliberate effort even with a steady stream of subscription titles. Cheaper third-party drives remain the sensible route, and the “officially licensed” label does not make the hardware faster than a well-reviewed alternative. The 8TB Optimus GX Pro 850P is built for a narrow audience – collectors and creators who want maximum capacity and Sony branding and are willing to pay a luxury markup for it.
The more practical move is to watch the wider memory market. Older SSD stock often drops around major retail events, and prices on this category may ease only when the underlying shortage loosens. Until then, console storage at the top end will keep looking more expensive than the console itself. The same scarcity-driven volatility recently shook memory-chip stocks in South Korea, a reminder that the price you pay for a PS5 drive is tied to forces far larger than the gaming aisle.
