So, for a 320GB hard drive, Windows will calculate it as having a capacity of 298GB (320,000,000,000/1,024/1,024/1,024=298GB).

Read speeds usually sit in the high 20s. Haven't tested it straight into a device, so speeds might improve, as shown by another customer with pictures (70+ mb).As for the capacity, as I see this argument popping up over and over again, please educate yourself why the advertised capacity by the manufacturer is different than the one showed by your computer. A simple google search will give you multiple articles regarding this.For all intents and purposes storage is calculated as you would weight, distance etc, by adding zeros to the end.so 1 Gigabyte (GB) = 1,000 megabytes (MB) etc.However due to how computers work, they will not show these values, but instead:1 Gigabyte (GB) = 1,024 megabytes etcThe bigger the drive is, the more capacity is "lost" in the listing of your device.128 gb = 1,099,511,627,776 bit1,099,511,627,776 bit = 137,438,953,472 byte137,438,953,472 byte = 134,217,728 kilobyte134,217,728 kilobyte = 131,072 megabyte131,072 megabyte = 128 gigabyteI made a quick calculation (which could be slightly incorrect, failed math):The amount you "lose" is as fallows:Gigabyte difference = 73,741,824 bytesSince per GB your are "losing" 73,741,824 bytes, then 73,741,824 bytes x 128 GB = 9,438,953,472 bytes, which converted to GB equals: 8.79071 GB (as shown in the picture).Windows machine shows 117 but if we add the "missing" 8.7gb = 125.7, which is closer to the advertised capacity.Also this might be true for write/read speeds as well, and the actual product does not advertise 95MB/s, rather "up to" which is correct.Does the job, but I would use it for complex write and read situations. Only really useful for mobiles and other hand held devices. ### ⭐⭐⭐⭐⭐ Great card at a great price *by on Reviewed in the United Kingdom 16 December 2025* Excellent micro sd card for my security camera, great price compared to others, highly recommend ### ⭐⭐⭐⭐⭐ Great (maybe overkill) for a 2DS *by on Reviewed in the United Kingdom 2 August 2023* I recently bought this to upgrade my cousin's 2DS to a 64GB card so they can play around with modding and homebrew. While the 2DS/3DS have class 4 slots, this is overkill in that regard; it is brilliant when transferring files over from the PC to the card. Works well, what more can I say. I also have the 128GB version in my Nintendo Switch and that has been going strong for many years. ## Frequently Bought Together - Transcend 4GB 300S, Memory Card, microSD, for Mobile Devices - TS4GUSD300S - Memory Card Reader, BENFEI 4in1 USB 3.0 and USB-C to SD Micro SD MS CF Card Reader Adapter, 4 Cards Simultaneously Read and Write, Compatible with iPhone 15 Series, MacBook Pro/Air 2023, and More - PSP Memory Stick Adapter, Funturbo Micro SD to Memory Stick PRO Duo MagicGate Card for Sony PlayStation Portable, Camera, Handycam --- ## 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.com.ar/products/154510475-transcend-4gb-usd300s-microsd-card-20mb-s-c10-2d-nand](https://www.desertcart.com.ar/products/154510475-transcend-4gb-usd300s-microsd-card-20mb-s-c10-2d-nand) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-20*
