I'm not sure if I just missed it, but the AmigaDiskBench tool that was recently released on Os4Depot is simply fantastic and up to date. I really like it.
So I thought I'd give this tool a try. I tested it with NGFS/01 Sata SSD Intern (AmigaOs4) NVME PcI-Express x4 (Download) and Ramdisk with my X5000/40.
I used the Bulk Benchmark for this, and maybe the results will be interesting for some of you.

MacStudio ARM M1 Max Qemu//Pegasos2 AmigaOs4.1 FE / AmigaOne x5000/40 AmigaOs4.1 FE
v2.3.7 (Current)
- S.M.A.R.T. column auto-fit: Attribute Name column now correctly expands to
show full text without truncation.
- Average method display: Benchmark Control row shows a single combined label
(e.g., "Average: Median (Middle Value Only)") next to the Passes count.
- Bulk tab Settings text: Queue summary now includes the averaging method name,
e.g., Settings: Sprinter / 10 Passes (Median) / 4K.
- Bug fixes.
v2.3.4 - v2.3.6
- Flexible Pass Averaging: Three averaging options -- All Passes, Trimmed Mean,
and Median.
- Average Method always visible on the Benchmark tab next to Passes count.
- Disk Info tree restructured: device name at root, VolumeName (Unit N) at
partition level, multiple units of the same controller merged.
- Bug fixes.
v2.2.16
- Disk Information Center: New hierarchical view of all physical storage
devices, categorized as Fixed, USB, and Optical.
- True Hardware Scanning: Engine directly probes the system to map logical
partitions to physical driver units.
- Enhanced CD/DVD Detection: Safeguards to prevent system freezes when
querying optical drives.
- Filesystem Display: Standardized DOS type formatting to ABC/XX hex notation.
- Bug fixes.
v2.2.14
- Release Optimization: Debug logging disabled for maximum performance.
v2.2.11
- Architectural Foundation: Multi-threaded benchmark engine, CSV history
persistence.
v2.2.10
- Advanced Graphing: Visualization engine overhauled; X-axis = Block Size;
auto-refresh on tab switch.
- Variable Workloads: Random I/O tests support dynamic user-selected block
sizes.
- Visual Feedback: Traffic Light status indicator and Fuel Gauge progress bar.
- Bug fixes.
Main Updates * New logging tab to show what is going on. * Visualization update - 9 template based charts as standard, and you can make your own. * IOPS calculation fix.
Version History
---------------
v2.5.3 (Current)
- VALIDATE mode improvements: Workbench validation window now displays columns
at correct proportions. Message column auto-fits to window width with
horizontal scrolling for long messages.
- VALIDATE usage: Run "AmigaDiskBench VALIDATE" from Shell, or add the tooltype
VALIDATE to the program's icon in the Information editor. The benchmark GUI
does not open -- only a validation report is shown (text report in Shell,
ReAction window from Workbench).
- Bug fixes:
- Blank window on Workbench launch: ReadArgs() was guarded by
Output() != NULL, but Output() can return a valid handle from Workbench
when a default console is configured. ReadArgs then blocked waiting for
interactive input, displaying an empty CON: window. Fixed by using
IDOS->Cli() (the canonical AmigaOS 4 method) to detect Shell vs Workbench.
- VALIDATE mode Shell/Workbench detection used the same unreliable Output()
check. Fixed to use IDOS->Cli().
- Profile validator falsely warned about DefaultDateRange and MinVersion keys
in the [Filters] section. Both are valid parser-recognized keys that were
missing from the validator's known-key list.
- Visualization hover tooltip and chart legend now replace underscores with
spaces in volume names (e.g., FFS2_DH8_2 displays as FFS2 DH8 2).
- Icon cleanup: Program icon now ships with a single (VALIDATE) tooltype
(commented out by default). Old template tooltypes removed. Drawer and
folder icons included for the distribution archive.
- Makefile "install" target: Now produces a complete distribution layout with
drawer icon, program icon, Visualizations folder icon, and readme.
v2.5.2
- Pluggable Visualization Profiles: Chart definitions are now loaded from .viz
files in the Visualizations/ folder. Nine built-in profiles ship with the
application: Scaling, Trend, Battle, Workload, Hybrid, Peak Performance,
IOPS Smoothed, Scaling Curve, and Filesystem.
- Profile-driven rendering: Each profile defines chart type (line/bar/hybrid),
X/Y axes, series grouping, data filters, trend lines, reference line
annotations, custom color palettes, and collapse aggregation -- all without
recompilation.
- Trend lines: Linear regression, moving average, and polynomial curve fitting,
rendered per-series or globally. Coordinate clamping prevents drawing outside
the chart area.
- Collapse aggregation: Reduce multiple runs at the same X value to a single
data point using mean, median, min, or max.
- Reference line annotations: Horizontal dashed lines with labels at user-defined
Y values (e.g., SATA III @ 600 MB/s).
- Custom color palettes: Up to 16 hex colors per profile.
- Reload Profiles button: Rescan the Visualizations/ folder for new or modified
profiles without restarting.
- VALIDATE mode: Shell argument or icon tooltype to validate all .viz files and
report errors with line numbers and severity.
- Quit confirmation dialog: Attempting to close the application while a benchmark
is running now shows a Yes/No confirmation prompt.
- IOPS calculation corrected: IOPS is now computed as total I/O operations
divided by total elapsed time (true ops/second). Previously, workloads
reported a fixed operation count of 1, and the engine averaged ops per pass
rather than per second.
- Bug fixes:
- Random 4K Write/Read and Mixed R/W benchmarks failed at 1M block size:
uint32 total_bytes overflowed (4096 ops x 1M = exactly 2^32, wrapping to
0). Fixed by using uint64 internally with a cap to UINT32_MAX.
- CSV history records silently truncated when field data exceeded the
1024-byte line buffer (producing malformed rows). Increased to 2048 bytes
with overflow detection -- oversized records are now skipped with a warning
in the session log.
- Benchmark failure messages in the session log were generic ("check target
volume"). Now reports the specific failure reason: setup failure (file
creation, device open, or buffer allocation), unknown test type, or all
passes producing zero bytes -- with test name, target path, and block size.
- Crash on exit while benchmarks are running (pending worker messages not
drained before freeing reply port).
- Blank window on Workbench launch (ReadArgs called unconditionally, failing
when launched from icon).
- Crash in CollapseSeriesPoints when series had no data points.
- Chart lines drawn outside the graph area (missing coordinate clamping in
line/hybrid renderers).
- Duplicate X-axis labels when all data points share the same block size.
- Color By dropdown removed -- now a read-only label driven by the active
profile's GroupBy setting.
- Unused filter dropdowns removed from the visualization tab.
v2.4.1
- Session Log tab: A new scrollable, timestamped log panel records all benchmark
activity in real time -- start, per-pass progress, results, and failures --
with [HH:MM:SS] timestamps.
- Live log updates: Cross-process Exec message passing delivers log entries from
the worker process to the GUI without polling or unsafe gadget access.
- Log context menu: Right-click for Select All and Copy.
- Copy to Clipboard button: Writes the entire log to the system clipboard via
IFFParse (FORM FTXT/CHRS format).
- Clear Log button: Wipes the transcript and re-inserts the session header.
- Bug fix: Classic menu selections were silently swallowed when a context menu
was also present. Fixed by checking WINDOW_MenuType before routing the
WMHI_MENUPICK event.
