My SanDisk Optimus GX PRO 850P review—Save your money
Most of my PlayStation time happens at a gaming lounge down the road, where a friend and I trade FIFA beatings. Of course, I’ve been circling the idea of buying my own PS5 for months, stuck on whether I’d touch it enough to justify the investment. So when SanDisk rolled out an officially licensed storage upgrade for the PS5 and PS5 Pro, my ears perked up. Then I saw the price, and my wallet left the room.
What a PS5 SSD shopper needs
A reader hunting for an M.2 NVMe Gen 4 SSD tailor-made for the PS5 and PS5 Pro has already settled the hard question and just wants the right drive. Form factor leads the checklist, since the console slot takes a PCIe Gen 4 stick in the M.2 2280 size and nothing else. Sustained read speed comes next, though the floor the console requires matters far more than the ceiling SanDisk advertises. A drive clearing that requirement loads games the same, whether it sits near the minimum or hits the 7,300 MB/s SanDisk quotes.
Cooling earns a spot on the list too, because the PS5 slot bakes a bare drive without a heatsink. The licensed SanDisk model bundles one shaped for the slot, yet a cheap third-party heatsink solves the same problem on any compliant drive. Capacity rounds out the priorities, and value per terabyte should steer that call more than a headline 8TB number most libraries never approach.
What doesn’t matter is the tailor-made badge itself. Official licensing, the PlayStation logo etched into the metal, sequential speeds far above what the slot can use, and chart-topping endurance ratings all read as marketing rather than function. A shopper who matches the Gen 4 spec and bolts on cooling gets the same in-game result for a fraction of the cost.
What SanDisk actually built
SanDisk Optimus GX PRO 850P NVMe SSD for PS5 consoles – 1TB
The Optimus GX PRO 850P is a PCIe 4.0 NVMe drive in the standard M.2 2280 form factor, which means it drops into the expansion slot on both the PS5 and PS5 Pro. SanDisk fits an exclusive heatsink on top, complete with a PlayStation logo, shaped specifically for that console slot so you skip the guesswork on cooling and clearance. Sequential read speeds land around 7,200 to 7,300 MB/s, depending on capacity, with writes up to 6,600 MB/s on the larger models. On paper, the hardware ticks every box Sony asks for.
Capacities run from 1 TB up to 8 TB, and the bigger you go, the more endurance headroom comes along for the ride. The 8 TB model carries a 4,800 TBW rating against 600 on the 1 TB, and all four sizes ship with a 5-year limited warranty. SanDisk pegs the 8 TB at roughly 200 games based on a 36 GB average install, which feels optimistic given how bloated modern titles have become. Still, the warranty and the official testing hand the lineup a baseline of credibility.
Then Sandisk tells you the price
The sticker is where my enthusiasm curdles. SanDisk lists the 8 TB at $2,959.99, marked down from $3,699.99, and frames that markdown as a deal. The 4 TB sits at $1,499.99, the 2 TB at $759.99, and even the entry 1 TB asks $379.99. Every one of those numbers arrives discounted, which tells you how unhinged the original pricing was.
Even the 2 TB version costs about $100 more than a standard PS5. You could buy the whole console over again and still pocket change before touching the 4 TB or 8 TB tiers. SanDisk blames the global memory shortage, fair enough, but the gap here stretches well past any reasonable explanation.
What that money buys everywhere else
A Western Digital drive with near-identical specs, made by Sandisk’s own parent brand, currently sells on Amazon for about $1,470, about half the price of the licensed 8 TB version. That same Western Digital SSD went for around $640 through retailers like Best Buy last year, working out to more than a 360% jump for the same capacity. Paying triple for a logo and a fitted heatsink looks absurd once I lay the numbers out plainly.
Stack the 8 TB price against the consoles themselves and the picture gets sillier. Sony’s PS5 Pro runs around $950 to $1,000, so the math lands at three Pros for one storage stick. Buying three entire consoles instead of a single upgrade should never read as the sensible alternative, yet here we are.
Does any capacity make sense?
Not every tier sits at the same level of ridiculous, so let me sort out where each one stands. The 1 TB at $379.99 earns a side-eye rather than an outright laugh, though a fresh PS5 with bigger onboard storage gets you closer to value anyway. A 2 TB option covers casual players who keep three or four titles installed, but it demands far too much against unlicensed drives that do the same job for less.
The 4 TB and 8 TB serve a buyer I struggle to picture. You’d need a sprawling library installed all at once, zero willingness to uninstall anything, and a budget that treats four figures as pocket money. I feel like the high-capacity models exist to anchor the lineup and make the smaller ones look reasonable by comparison.
Who should buy it, and what I’d do instead
My verdict won’t shock you. Almost nobody should buy the licensed SanDisk drive at these prices, full stop. The official testing and the tidy heatsink count as nice touches, yet they fall nowhere near justifying double or triple the cost of an equivalent unlicensed NVMe SSD that slots into the same expansion bay.
As for my own PlayStation debate, the whole saga nudged me further toward staying a guest at the lounge. Dropping console money on storage I’d barely fill makes no sense for someone whose FIFA habit lives at a friend’s elbow. Anyone committed to a packed PS5 library would still save hundreds by grabbing a standard PCIe 4.0 drive with a third-party heatsink and skipping the logo tax.
The reviews already tell the story, with the 8 TB version holding at a flat 1.0 stars on SanDisk’s own page. When the niche buyers most likely to want such a drive end up irritated, the message comes through loud and clear. Save your money—and let the logo tax gather dust.
