🚀 Key Features

⏱️ Performance Benchmarking (Disk Speed)

• Multi-Workload Testing:
  • SEQ1M Q8T1: Sequential 1 MiB block reads and writes (Queue Depth 8, 1 Thread) — tests peak drive throughput.
  • SEQ1M Q1T1: Sequential 1 MiB block reads and writes (Queue Depth 1, 1 Thread) — tests single-request sequential performance.
  • RND4K Q32T1: Random 4 KiB block operations (Queue Depth 32, 1 Thread) — tests deep queue NVMe/SSD random access.
  • RND4K Q1T1: Random 4 KiB block operations (Queue Depth 1, 1 Thread) — tests real-world application responsiveness and OS boot latency.
• Microsecond Latency Measurements: Live monitoring of read and write latency (avg $\mu s$) alongside IOPS and MB/s throughput.
• Customizable Profiles: Tailor test file size (64 MiB to 64 GiB), test iterations (1 to 9 runs), queue depth, and thread counts.
• Bundled Microsoft DiskSpd 2.2: Utilizes Microsoft's official, rock-solid storage evaluation engine (diskspd.exe) for reproducible, standardized results.

🩺 S.M.A.R.T. Health & Storage Diagnostics (Disk Info)

• Deep Hardware Telemetry: Direct Win32 DeviceIoControl querying of physical drives for ATA and NVMe controllers.
• NVMe SMART / Health Information Log:
  • Critical warning flags & composite temperature
  • Available spare percentage & available spare threshold
  • Percentage used (endurance indicator)
  • Data units read / written (in TB/GB)
  • Host read / write commands count
  • Controller busy time & power cycles
  • Power-on hours & unsafe shutdowns
  • Media errors and error information log entries
• ATA / SATA S.M.A.R.T. Attributes: Decodes standard SMART registers (Reallocated Sectors, Wear Leveling, Spin-Up Time, CRC Errors, and more).
• Physical Drive & Partition Mapping: Displays partition layout, drive letters, volume labels, file systems (NTFS, exFAT, ReFS), total capacity, and available free space.

💎 Modern Windows Experience

• Fluent Design & WinUI 3: Native Windows 11 Mica backdrop, rounded geometry, and dynamic light/dark theme adaptation.
• Background Tray Integration: Minimize to notification area with single-instance restoration and system startup option.
• 100% Private & Offline: Zero analytics, zero telemetry tracking, and zero internet phone-home connections.

🛠️ Architecture & Technology Stack

• UI Framework: WinUI 3 via Windows App SDK 2.4
• Runtime: .NET 8.0 (net8.0-windows10.0.19041.0)
• Pattern: Model-View-ViewModel (MVVM) powered by CommunityToolkit.Mvvm 8.4
• Data Presentation: CommunityToolkit.WinUI.UI.Controls.DataGrid
• System Tray: H.NotifyIcon.WinUI
• Low-Level Native Calls: Win32 IOCTLs (IOCTL_STORAGE_QUERY_PROPERTY, IOCTL_STORAGE_PROTOCOL_COMMAND, SMART_RCV_DRIVE_DATA)
• Benchmark Engine: Microsoft DiskSpd 2.2 (bundled for amd64 and arm64)
