Manufacturer description
Samsung's MUF-512DA4/AM puts 512GB of USB 3.2 Gen 1 storage behind a reversible USB-C plug, and it moves data fast enough to matter: read speeds reach 400MB/s, which Samsung rates at roughly 15 seconds for a 4GB file. That makes this Samsung Type-C flash drive a practical shuttle for 4K footage, project archives, and large game or design files rather than a drive you tolerate for small documents. The USB-C connector plugs straight into modern laptops, tablets, and phones, and the drive stays backward compatible with USB 3.0 and 2.0 hosts through an adapter. At 512GB, it supports iPhone 15…
SpecPicks Verdict
SpecPicks scored Samsung Type-C USB Flash Drive 512GB using a rating × review-volume × price-fit model applied to published specs and reviews across the external storage category. Samsung's external storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for external storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
How fast is the Samsung 512GB Type-C flash drive?
Read speeds reach up to 400MB/s over USB 3.2 Gen 1, which Samsung says transfers a 4GB file in about 15 seconds. That figure was measured on an Asus Z370-G with an Intel i7-8700K and Windows 10; actual speed varies by host device.
Will this work with my phone or tablet?
It uses a USB Type-C plug, so it connects directly to phones, tablets, and laptops with a USB-C port. Samsung notes host device compatibility may vary, so confirm your device supports USB mass storage before buying.
Can I record 4K video straight to this drive?
Yes. The 512GB and 256GB models support iPhone 15 ProRes 4K recording at 30fps directly to the drive. The 64GB and 128GB versions are limited to ProRes 1080p at 30fps.
Is it waterproof and durable enough to carry on a keychain?
Samsung rates it for up to 72 hours at 1 meter in seawater, up to 1,500G of shock, and up to 15,000 gauss of magnetic exposure, equal to an MRI. Those ratings cover the common hazards of daily carry.
Does it still work on older USB-A ports?
It is compatible with USB 3.0 and 2.0 hosts, but the plug is USB-C, so a USB-C to USB-A adapter is required on older machines. Speeds on a USB 2.0 port will fall well below the 400MB/s rating.
