SanDisk Ultra 32GB MicroSDHC Card for Roku

The SanDisk Ultra 32GB MicroSDHC is purpose-matched storage for Roku streaming devices that support microSD expansion — specifically the Roku 2, 3, 4, and Ultra. Its Class 4 rating guarantees a minimum sustained read speed of 4MB/s, which directly aligns with the transfer rate Roku specifies as its microSD minimum. At 32GB, it provides comfortable capacity for Roku's storage workload: the platform uses the card for channel data, channel artwork, and cached content, none of which approach the throughput demands that would require a faster speed class. The MicroSDHC form factor slots directly into compatible Roku models without an adapter, and the card is ready to be formatted by the device on first insertion.

The bundle includes an Everything But Stromboli card reader for connecting the card to a PC without a built-in microSD slot — a practical addition for users who want to inspect card contents or perform initial setup from a computer. This card is designed for the Roku user who wants a reliable, validated expansion solution without navigating spec sheets. It does one job well and it does it for the devices it's rated for. Users looking to repurpose this card in cameras, drones, or any application requiring Class 10 or UHS-I performance should look elsewhere — but for Roku's specific low-demand storage use case, it's a clean, no-friction solution.
