WD Black SN770M 2TB Drops to $259.99 in Handheld Upgrade Opportunity
WD Black SN770M 2TB falls to $259.99, or about $0.13 per GB, suiting handheld storage upgrades.
High-capacity SSD prices for handheld gaming devices are regaining stability. According to reporting by Zhiye Liu of Tom’s Hardware, the WD Black SN770M 2TB has fallen to $259.99 at Best Buy in the U.S. That works out to about $0.13 per GB, close to pre-shortage street levels. For users struggling with limited internal storage on handhelds, it is a price worth considering.
This article is based on Tom’s Hardware (All Rights Reserved) and relies on fair quotation under Article 32 of Japan’s Copyright Act. The key point of the original is summed up in the following line.
The WD Black SN770M 2TB has fallen to $259.99, just 8% above its original launch price.
Although three years have passed since its release, options in the small M.2 2230 form factor remain limited. As such, this price move serves as an indicator for the broader handheld upgrade market.
Compact Standard Ideal for Handhelds
The WD Black SN770M is an SSD compliant with the M.2 2230 standard. It uses a compact 30mm board and fits major handhelds including Steam Deck, ROG Ally, Legion Go, and Claw. Shorter than the M.2 2280 standard common in desktops and laptops, it is designed to fit the tight internal space of handhelds.
The largest M.2 2230 capacity currently available to general consumers is 2TB. Although Micron has announced a 4TB M.2 2230, supply is limited to OEMs. For now, 2TB remains the practical ceiling for handheld storage upgrades.
Interest in handheld teardowns and SSD swaps remains strong. As End of Steam Deck Parts, Standalone ROG Ally Sales, Google Play Opening shows, parts availability and repair support directly affect users’ maintenance costs. Swapping the internal SSD can resolve storage shortages without replacing the device itself. Stable pricing for the compact form factor helps support long-term use of handhelds.
5,150MB/s Performance and Compatibility
The drive supports a PCI Express 4.0 interface. It is rated for sequential reads of up to 5,150MB/s and sequential writes of up to 4,850MB/s. That is fast enough to help cut boot times and load large games on handhelds.
There are compatibility caveats, however. The Steam Deck’s internal interface is limited to PCI Express 3.0. The SN770M therefore cannot deliver its full performance. In Tom’s Hardware’s assessment, it is positioned as a drive with performance to spare for Steam Deck use.
On PCIe 4.0-compatible models such as the ROG Ally and Legion Go, however, the rated speeds can be utilized. Even after the arrival of newer models like the successor-class Optimus GX 7100M, the SN770M is still seen as a balanced choice of price and performance. Given the heat and power constraints of handhelds, an excessively fast SSD is not always advantageous. In real-world use, cost per capacity and stability often matter more.
Trends in handheld accessories are linked to hardware refresh cycles. The strong demand seen in Steam Controller Reservations Surge, New Orders Delayed to 2027 reflects high interest in handhelds and their ecosystems. SSD upgrades can likewise be seen as an investment that extends the value of existing devices.
Price History and Discount Claims Examined
The SN770M 2TB launched with a suggested retail price of $219.99. Street prices later hovered around $239.99. During the shortage, prices rose to between $349.99 and $399.99.
The current $259.99 is about 8% above the pre-shortage street price. At $0.13 per GB, the unit price is competitive for a 2TB M.2 2230 drive. Best Buy lists it as 51% off a comparison price of $531.99. That implies a discount of $272.
However, the $531.99 comparison price is far removed from market reality. It is even higher than peak shortage pricing, making the discount rate appear inflated. A more realistic assessment is that the price is moving back toward its launch level. The proper benchmark is the former normal price of around $239.99, not past inflated highs.
Handheld Upgrade Market and Options
The M.2 2230 market has few suppliers and is prone to large price swings. Production volumes are smaller than for desktop-oriented M.2 2280 drives, making it vulnerable to shortages. The return of 2TB models to $259.99 is therefore significant. It improves cost predictability for handheld users planning upgrades.
An alternative is expansion via external microSD cards. MicroSD cards are easy to swap and cheaper. Internal SSDs, however, have the edge in read/write speeds and endurance. Upgrading the internal SSD is effective when keeping multiple large games installed or prioritizing load times.
Use of handhelds in Linux environments is also growing. Foundational improvements such as Mesa Rusticl Enables Mali Panfrost by Default support handheld use in open environments. With ample internal capacity, it becomes easier to run multiple OS or development environments side by side. SSD upgrades can thus be seen as more than just extra game storage.
Compatibility checks are essential before purchase. Buyers need to confirm they are not confusing M.2 2230 with M.2 2280, check single-sided versus double-sided layouts, and consider thermal measures. It is also advisable to review the handheld maker’s warranty terms in advance. Decisions should be based on total cost, including installation steps and tools, not price alone.
Editorial Opinion
On the short-term impact: Over the next three to six months, we expect rival 2TB M.2 2230 models to follow suit. The SN770M at $259.99 should help cap prices across the market. We expect spillover to the used market and high-capacity microSD cards, widening choices for handheld upgrade costs.
On the long-term outlook: Over one to three years, the focus will be on whether 4TB M.2 2230 drives reach general retail. As long as Micron’s supply remains OEM-only, 2TB may remain the practical ceiling. If handhelds keep getting more powerful and game sizes keep growing, more users may find even 2TB insufficient.
A question from the editorial team: Doubts remain over whether the advertised 51% discount reflects reality. There is also the question of who verifies the validity of comparison prices. Learning from the shortage-era surge, ensuring transparency in price history is the key issue.

- Is there any point in using a PCIe 4.0 SSD in a Steam Deck?
- The Steam Deck's internal interface is PCIe 3.0, so full speeds cannot be reached. Still, it can be a viable option considering cost per capacity and future reuse. Heat and power consumption should be weighed in an overall decision.
- Is Best Buy's 51% off claim a good deal?
- The $259.99 price itself is close to pre-shortage levels and reasonable. The $531.99 comparison price, however, is above market reality and inflates the apparent discount. It should be judged against the $219.99 launch price and the former street price of around $239.99.
