In this part of the video, the presenter discusses using a 400GB SanDisk Extreme Pro micro SD card to expand the storage on their Surface Pro 6. They explain that the Surface Pro 6 only has 256GB of built-in storage, which quickly fills up with the OS and essential apps. By using the micro SD card, they significantly increase the device’s storage without relying on external hard drives. The presenter highlights the card’s high storage capacity, fast read and write speeds, and versatility for use in other devices such as action cameras and Android phones. They also mention purchasing the card secondhand at a lower price and provide details about different capacities and price points available for the SanDisk Extreme Pro micro SD card.

In this part of the video, the speaker discusses purchasing a high-capacity SD card second-hand from CEX to save money and the steps taken to verify its authenticity and performance. The speaker used H2testW to confirm the card’s 375GB capacity and checked its read and write speeds, which were 58.3 MB/s and 66.4 MB/s, respectively. Though these speeds were lower than advertised, the performance on a Poco phone showed reasonable sequential read and write speeds, indicating the card is suitable for mobile use. Additionally, the speaker tested the SD card on an HP laptop using a Thunderbolt 3 card reader and observed impressive write speeds of 84 MB/s, which were close to the advertised speeds, suggesting good performance through the card reader.

In this part of the video, the presenter conducts tests using a Surface Pro 6 and a card reader to evaluate data transfer speeds. They initially observe speeds of 82 and 90 megabits per second through a USB 3.0 Type-A port, but these decrease when using Crystal Disk Mark to 85 and 74 megabits per second for reading and writing respectively. Directly testing on the Surface Pro yields slightly different results, with 79.3 for reading and 77 for writing. The presenter notes that actual file transfer speeds will generally be lower due to various factors. They prefer using a different storage device, the T5, due to its more consistent and higher transfer rates of over 400 read and write speeds. Despite the variability in microSD card speeds, the presenter still finds value in them for specific uses, such as with multiple cameras.

In this part of the video, the speaker discusses the benefits of using the SanDisk Extreme Pro micro SD card. They highlight its substantial storage capacity, suitability for extensive video recording, and utility when access to a laptop for file transfer is limited. The card is also praised for being a practical solution for mobile phones and devices with limited USB ports, such as the Surface Pro. Although the transfer speeds don’t always meet the advertised rates, the card is deemed reliable for backup storage. The speaker concludes that, despite being purchased secondhand, the SanDisk Extreme Pro has proven to be a worthwhile investment.
