If you have an extra Gen3 NVMe or SATA M.2 drive lying around and gathering dust, the WH51 is one of the best-value enclosures on the market to turn it into a blazing-fast, pocket-friendly flash drive. However, be aware that pairing this enclosure with a high-end Gen4 NVMe drive may result in significant overheating during prolonged heavy workloads, such as hours of video rendering. For such usage, this enclosure may not offer adequate heat dissipation.
The Netac WH61S is budget-friendly and functional. It is a USB 3.2 Gen 2 (10Gbps) enclosure with good build quality for the price. However, it has thermal limitations with high-end drives. The metal shell is enough for small file transfers, but high-performance drives can reach nearly 80°C. It's a good option if you have old storage lying around and want a portable drive.
