A Familiar Face for Your PS5 Storage Expansion
SanDisk has launched its new Optimus GX Pro 850P 2TB SSD, targeting PlayStation 5 users seeking expanded storage. At first glance, it presents as a new contender in the competitive PS5 SSD market. However, a closer inspection reveals a familiar story: the Optimus GX Pro 850P is, by all accounts, a rebadged Western Digital WD_BLACK SN850P SSD. This means users are getting a drive with a proven track record of performance, but the question quickly becomes whether the SanDisk branding justifies a price that, according to Tom's Hardware, carries a stiff premium.
The SN850P has been a popular choice for PS5 owners due to its adherence to Sony's M.2 SSD requirements, including its PCIe Gen4 interface and specified read/write speeds. The Optimus GX Pro 850P inherits these specifications, promising sequential read speeds of up to 7,300 MB/s and sequential write speeds of up to 6,600 MB/s. These figures place it firmly within the recommended performance tier for PS5 games, ensuring quick load times and smooth gameplay. The drive also comes with a heatsink pre-installed, a crucial component for maintaining optimal operating temperatures during extended gaming sessions, and a requirement for any M.2 SSD installed in a PS5.
From a performance perspective, the Optimus GX Pro 850P delivers what the SN850P is known for. Tom's Hardware reports that the drive performs admirably in real-world scenarios, particularly when tested within the PS5 environment. Load times for demanding titles are comparable to other high-end PCIe Gen4 SSDs, and the drive maintained stable performance even under sustained load. This consistency is key for gamers who want a reliable storage solution that won't bottleneck their gaming experience.

The Premium of Familiarity
The core of the SanDisk Optimus GX Pro 850P's value proposition lies in its dual nature: it's a recognized performer in a new package, but one that commands a higher price than its Western Digital counterpart. This pricing strategy is a curious one. Typically, rebadged products might offer a slight discount or an alternative aesthetic. Here, the premium seems to stem from the SanDisk brand itself and perhaps a specific marketing push towards the PlayStation ecosystem. For consumers, this presents a dilemma: do you pay extra for the SanDisk name on a drive that is functionally identical to the WD_BLACK SN850P, or do you opt for the original and save money?
This situation highlights a broader trend in the storage market, where branding and ecosystem partnerships can influence perceived value. Western Digital, the parent company of SanDisk, effectively leverages its own product lines under different banners. While this can offer consumers choice, it also requires careful consideration of the actual product and its price point. The Optimus GX Pro 850P is, without question, a competent PS5 SSD. It meets all the technical specifications, includes a necessary heatsink, and offers the performance expected from a drive based on the SN850P architecture. The issue is not one of capability, but of cost-effectiveness.
What remains to be seen is how this pricing strategy will play out in the market. Will SanDisk's brand recognition in the consumer storage space be enough to command a sustained premium over its own sibling product? Or will savvy consumers gravitate towards the WD_BLACK SN850P, recognizing the identical performance for a lower cost? The success of the Optimus GX Pro 850P may hinge on aggressive promotional pricing or bundle deals that can offset the initial higher cost. Without such incentives, its appeal is largely limited to those who specifically seek out the SanDisk brand for their PS5 storage needs.
Performance Benchmarks and PS5 Compatibility
In testing by Tom's Hardware, the SanDisk Optimus GX Pro 850P consistently met its advertised speeds. While synthetic benchmarks might show slight variations between the SanDisk and WD versions due to firmware or controller nuances, the real-world impact on PS5 game loading times is negligible. The drive's PCIe Gen4 x4 interface, coupled with its NVMe protocol, ensures it easily surpasses the PS5's minimum speed requirements, which are crucial for playing the latest generation of games directly from the expanded storage.
The integrated heatsink is a significant advantage, as it removes the need for users to purchase and install a separate cooling solution. This simplifies the installation process, making it more accessible for less technically inclined users. The heatsink's design is also optimized for the confined space within the PS5's M.2 slot, ensuring efficient heat dissipation without interfering with other components. This attention to detail in the form factor is what makes drives like the SN850P and, by extension, the Optimus GX Pro 850P, excellent choices for the console.
The 2TB capacity offers substantial room for a growing library of PS5 games, which can easily exceed 100GB each. This means users can install dozens of titles without constantly needing to manage storage space, a common pain point for PS5 owners with the console's internal drive alone. The reliability of the underlying NAND flash and controller technology, inherited from the SN850P, suggests a long lifespan for the drive, even with intensive use.
Conclusion: A Solid Drive, But Is It Worth the Price?
The SanDisk Optimus GX Pro 850P 2TB SSD is, by all objective measures, a high-performing and reliable storage solution for the PlayStation 5. It offers the speed, capacity, and essential features like an integrated heatsink that gamers demand. Its performance is on par with established drives in the market, ensuring a smooth and responsive gaming experience.
However, the primary critique leveled against it is its pricing. When compared directly to its nearly identical sibling, the WD_BLACK SN850P, the SanDisk Optimus GX Pro 850P often comes with a higher price tag. This premium is difficult to justify purely on technical merit, as the core components and performance characteristics are the same. For consumers looking for the best value, the WD_BLACK SN850P remains the more sensible choice. The SanDisk Optimus GX Pro 850P exists as a viable, albeit more expensive, alternative for those who prioritize brand name or specific retail availability, but it doesn't offer a compelling reason to choose it over its more affordably priced counterpart.
