Does MD100 get hot during use?

It's normal for MD100 to feel warm during intensive transfers. The aluminum alloy shell is designed to dissipate heat efficiently. Normal operating temperature: 0°C to 45°C (32°F to 113°F). During large file transfers, surface temperature may reach 40-45°C. The drive will throttle automatically if temperatures exceed safe limits. Tip: Avoid placing the drive on soft surfaces (bed, sofa) during heavy use. Allow air circulation for optimal cooling.

The MD100 is OSCOO's flagship portable SSD: USB 3.2 Gen2×2 (20Gbps) speeds in a full aluminum alloy body, with magnetic attachment for phone-mounted recording. Independently tested by SSD-Tester.com (Germany/Austria), the MD100 512GB earned Test Winner status with an AS SSD score of 1247.

Who it's for: iPhone and Android videographers recording ProRes/4K directly to external storage; photographers offloading cards in the field; anyone who wants a compact drive with premium build quality backed by independent testing.

MD100 or MD200? Both share the same 2,100 MB/s performance and magnetic attachment. Choose the MD100 for its full aluminum body and square profile; choose the MD200 if you want the thinnest, lightest option (8 mm, 40.5 g) behind your phone.

FAQ:

Will I get 2,100 MB/s on my computer? Full speed requires a USB 3.2 Gen2×2 (20Gbps) port. On the more common 10Gbps USB ports — including all iPhones, Macs, and Thunderbolt ports — real-world speeds are around 900–1,000 MB/s, still well above what ProRes 4K recording requires.
Does the included cable support full speed? Yes — the included USB-C cable is rated for 20Gbps (Gen2×2). No separate cable purchase needed.
How does it attach to my phone? Stick the included magnetic ring on your phone or case; the MD100 snaps on and off.
Does it work with iPhone ProRes recording? Yes — connect via USB-C (iPhone 15 or later) and select the drive as the storage destination in the Camera app.

All OSCOO products come with a 3-year warranty.

Frequently Asked Questions

This resource is crafted to help you find information easily and efficiently.

Q1: Which file systems does MD100 support?

The MD100 supports all common file systems: exFAT, NTFS, FAT32, APFS, ext4.

Recommendation: Keep exFAT for cross-platform use. Use APFS for Mac-only backup.

Q2: Does MD100 support 20Gbps transfer speed?

Yes, MD100 features USB 3.2 Gen2×2 technology with up to 20Gbps transmission rate, delivering speeds of up to 2100MB/s read and 1900MB/s write. However, achieving these speeds requires a compatible 20Gbps USB port on your host device.

Q3: Can MD100 attach to any phone or tablet?

MD100 uses magnetic attachment, so it works best with devices that have built-in magnetic functionality (like iPhone 12 and newer) or when used with a magnetic case. For devices without magnetic features, you'll need a magnetic case or adhesive magnetic ring to enable the attachment.

Q4: Does the MD100 get hot during use?

A: It's normal for the MD100 to feel warm during intensive transfers. The aluminum alloy shell is designed to dissipate heat efficiently.

Normal operating temperature: 0°C to 45°C (32°F to 113°F)
During large file transfers: Surface temperature may reach 40-45°C
The drive will throttle automatically if temperatures exceed safe limits

Tip: Avoid placing the drive on soft surfaces (bed, sofa) during heavy use. Allow air circulation for optimal cooling.

Q5: How do I format my MD100 for the first time?

A: The MD100 comes pre-formatted as exFAT for cross-platform compatibility. To reformat:

Windows: Right-click the drive → Format → Select file system → Start
Mac: Open Disk Utility → Select MD100 → Erase → Choose format → Click Erase
Backup first: Formatting will erase all data on the drive

Q6: Does MD100 work with iPhone 15/16 Pro for ProRes recording?

Yes, MD100 is fully compatible with iPhone 15/16 Pro series for external ProRes recording. The magnetic design keeps it securely attached to your iPhone, enabling 4K 60fps and 4K 120fps ProRes video recording directly to the drive without filling up your internal storage.

Q7: What's the difference between MD100 and MD200?

While both are 20Gbps magnetic portable SSDs, MD100 features a unique 360° rotatable ring stand that functions as a kickstand and hanging loop, with a slightly thicker 12mm profile. MD200 is ultra-slim at 8mm and focuses on a minimalist design without the stand. Choose MD100 for the built-in stand functionality, or MD200 for the slimmest magnetic attachment possible.
