A 2TB Steam Deck-sized SanDisk SSD falls to $398.52, with up to 7,250MB/s reads
Amazon lists the 2TB SanDisk Optimus GX 7100M SSD for $398.52, $51.47 below its displayed $449.99 typical price. The short M.2 2230 drive is sized for compatible handhelds including Steam Deck, as well as suitable laptops and tablets.
The new drive was in stock, sold and shipped by Amazon.com when checked. The page also offers a 1TB model, so check the selected 2TB capacity before ordering. No coupon or membership was shown as necessary for the listed price.
Amazon labels $449.99 as a typical price. That establishes the retailer's comparison, not an independently verified all-time low. At nearly $400, the drive remains a significant purchase even after the reduction.

A compact SSD for a handheld upgrade
The Optimus GX 7100M uses the M.2 2230 form factor and a PCIe 4.0 x4 interface. SanDisk rates this capacity for sequential reads up to 7,250MB/s and writes up to 6,900MB/s. Those are manufacturer figures under stated test conditions; actual speeds depend on the host device and workload.
Size is the useful detail for handheld buyers: many full-length M.2 2280 drives will not fit the same space. SanDisk identifies compatible Steam Deck systems in its product data sheet. Check the requirements of your exact device before purchasing.

Plan the installation, not just the capacity
Replacing an internal SSD requires opening the device and preparing its software. Back up your files first and follow the device maker's instructions; the advertised 2TB capacity will also leave less usable space after formatting.
SanDisk lists a five-year limited warranty for the drive. Its Dashboard software is for Windows, so SteamOS users should not assume that tool runs natively on their handheld. The offer may change.
