50 Gb Test File [work] Access
Warning: Random generation on 50GB takes significant CPU time. Use the fsutil method for pure throughput testing.
A modern PCIe 4.0 NVMe SSD might copy 50 GB in ~7 seconds (7 GB/s), while a 7200 RPM HDD takes ~100 seconds (500 MB/s) — but only if the HDD is unfragmented. The test file also exposes thermal throttling in portable SSDs. 50 gb test file
