The problem

Every existing tool has a gap.

SQLIO was retired. CrystalDiskMark has no SQL-aware profiles. Raw DiskSpd is command-line only. dp-sqlio fills the gap.

Retired

SQLIO

Microsoft's original SQL Server IO test tool. Deprecated and removed — no longer available or supported.

No SQL Profiles

CrystalDiskMark

Great for generic benchmarks. Uses DiskSpd internally but has no OLTP, Transaction Log, or TempDB presets.

Recommended

dp-sqlio

DiskSpd engine. SQL Server workload profiles. GUI with instant results, reports, and run history. Self-contained — no runtime to install.

Workload profiles

7 SQL Server presets, ready to run.

Each profile matches a real SQL Server IO pattern — correct block size, queue depth, read/write mix and sequential vs. random access.

OLTP — Data (8K) 8K block Random 32q · 70R/30W
OLTP — Data (64K) 64K block Random 32q · 70R/30W
Transaction Log 64K block Sequential 1q · 100W
TempDB 8K block Random 32q · 50R/50W
OLAP / Data Warehouse 512K block Sequential 16q · 100R
Backup Throughput 1M block Sequential 8q · 100R
CrystalDiskMark Compatible Mixed Mixed Mixed

Features

More than a benchmark runner.

Auto-detects SQL Server

Scans the registry for installed instances, reads data, log, and tempdb file paths, then recommends the matching profile — no manual configuration.

Pre-flight checks

Verifies admin rights, power plan (High Performance), and free disk space before every run. Issues are flagged with one-click fixes.

Rich reports

Offline HTML with Chart.js latency percentile graphs, PDF summary via QuestPDF, CSV for Excel. Run history stored locally for side-by-side comparison.

No runtime required

.NET 8 self-contained, single-file publish. Extract and run on any Windows Server 2016+ or Windows 11 machine — no SDK, no installer prerequisites.

Customisable profiles

All 7 built-in profiles are fully editable. Adjust block size, queue depth, duration, and read/write ratio. Save custom profiles to profiles.json.

Code-signed packages

All three delivery formats — ZIP, .exe, and .msi — are signed with the DP Data Platform certificate so Windows SmartScreen stays silent on locked servers.
