50 Gb Test File [portable]

✅ – Compute a hash (MD5, SHA-256) of the file before and after transfer to check for corruption. ✅ Use clean test environments – Close other apps to avoid interfering with bandwidth or I/O. ✅ Repeat tests – Run 3-5 times and average results due to caching and background processes. ❌ Avoid loading as entire file into RAM – A 50 GB file will exhaust typical system memory (16-32 GB) if fully read into RAM.
