Kingston Canvas Select Plus 128GB SDCS2
Score: 65/100Rankings
The SanDisk Ultra 128 GB SDXC card offers fast read performance, A1 app capability, and a robust, water- and shock-resistant design, backed by a 10-year warranty. Its U1/V10 rating and modest write speeds keep it in the budget tier, making it unsuitable for 4K or high-bitrate video work.
The Kingston Canvas Select Plus 128 GB provides reliable Full HD performance, solid durability and a lifetime warranty at a budget-friendly price, but it lacks the higher speed classes needed for 4K video and high-speed write-intensive tasks.

Professional reviewers praise the Ultra 128 GB for its reliable read performance, solid random I/O that exceeds the A1 specification, and overall value, but caution that its U1/V10 write class makes it unsuitable for 4K or high-bitrate video work.
Everyday users consistently highlight fast photo transfers, smooth app performance on Android devices, and the sturdy SD adapter, while noting slower write speeds, occasional incompatibility with dashcams or drones, and rare corruption when the card is not ejected properly.
“Works perfectly with my Samsung Galaxy phone-apps load faster.”
“Used it in my GoPro-recorded Full HD videos without any issues.”
“Great for my Nintendo Switch-loads games quickly and has plenty of space.”
Choose Kingston for better warranty and durability; choose SanDisk if you prefer brand familiarity.
Professional reviewers consistently commend the Canvas Select Plus for its dependable performance, A1 app optimization, and rugged build, positioning it as a solid everyday microSD solution. However, they all agree that the card falls short for 4K video or high-performance camera needs because it lacks V30/U3 certification.
Everyday users overwhelmingly praise the card for faster app launches, reliable Full HD recording, and the peace of mind from a lifetime warranty. The main complaints revolve around its inability to handle 4K video smoothly and occasional confusion over slightly reduced usable capacity after formatting.
