For sequential writes, the speed goes up and down constantly. The lowest write speed it gets is 18 MB/s which does not meet U3's Minimum sequential write speed of 30 MB/s. And the highest write speed it reaches is 67 MB/s. This is why the CrystalDiskMark benchmarks shows a higher speed than it really is. The speed shown is not the sustained write speed. Also, there's a slight delay before it actually starts writing to the card. Read speeds are fast at 90 MB/s though. I don't recommend the 1 TB version. ### ⭐⭐⭐⭐⭐ Unbelievable value for money *by on Reviewed in Australia 10 September 2024* The cheapest 1TB micro SD around and it delivers on the promised capacity, providing incredible performance for the price. I've been using this in my Retroid Pocket 4 Pro handheld and it runs even the most demanding games without causing slowdowns. I wouldn't hesitate to buy another one of these next time I need a micro SD card.Forget about Sandisk and their overpriced cards that fall apart and have compatibility issues with some devices, and Samsung who don't even make 1TB cards yet. If you need a 1TB microSD card then Silicon Power is the only option you should consider. ## Frequently Bought Together - Silicon Power 1TB microSDXC UHS-I Micro SD Card with Adapter, Up to 100MB/s Read & 80MB/s Write, Class 10 U3 V30 A2 Faster App Performance 4K UHD Video, High Speed Memory Card, Superior A2 Series - SanDisk Extreme Pro 256GB microSDXC UHS-I, V30, 200MB/s Read, 140MB/s Write, Memory Card for 4K Video on Smartphones, Action Cams and Drones - UGREEN Micro HDMI to HDMI Cable, Type D Male to Type A Female Adapter, Supports 4K 3D for GoPro Hero 5 Raspberry Pi 4 (Not Micro USB) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/775214755-silicon-power-1tb-superior-micro-sdxc-uhs-i-u3-a2](https://www.desertcart.us/products/775214755-silicon-power-1tb-superior-micro-sdxc-uhs-i-u3-a2) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-05*
