TC Block Transfer Bench is a multi-block-size storage throughput benchmark
utility for Linux desktops and workstations. An independent Linux alternative
inspired by ATTO Disk Benchmark, it measures genuine filesystem Read and Write
transfer rates across stepped block sizes from 512 B up to 16 MB.
Key Features:
- Stepped multi-block-size benchmarking across 16 power-of-two transfer sizes:
512 B, 1 KB, 2 KB, 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, 128 KB, 256 KB, 512 KB,
1 MB, 2 MB, 4 MB, 8 MB, and 16 MB.
- Safe temporary file Read & Write throughput testing (MB/s, IOPS, and latency)
on any mounted directory with automatic cleanup after every run.
- Classic dual horizontal Write/Read throughput bar chart with live progress.
- Detailed transfer matrix analyzing small, medium, and large block efficiency.
- Real Linux mount & block queue inspector (/proc/mounts, statvfs, /sys/block).
- Export complete benchmark results to CSV, JSON, and TXT reports.
