About
Provides benchmark results for Solid State Drives (SSDs) and traditional Hard Disk Drives (HDDs). The data is designed to score performance based on a standardised series of tests, facilitating easy comparison between multiple storage drives. This information is highly valuable when undertaking the purchasing or building of a new personal computer. The core performance metric,
diskRating, is derived from the average results of Sequential Read, Sequential Write, Random Seek Read/Write (IOPS 32KQD20), and IOPS 4KQD1 testing. The most recent information included in the dataset is current as of May 4th, 2022.Columns
The dataset contains 10 key attributes:
- driveName: The specific model identification for the storage drive.
- type: Indicates the category of the drive, either SSD (Solid State Drive, approximately 70% of entries) or HDD (Hard Disk Drive, approximately 30% of entries).
- diskCapacity: The total storage capacity of the drive, measured in gigabytes (GB). Capacities range from 0.57 GB up to 14.6 TB.
- diskMark: The calculated Disk Rating, where a higher score signifies better overall performance. Scores range from 89 up to 52.3k.
- rank: The benchmark rank assigned to the drive model.
- price: The last recorded market price for the drive, denominated in USD ($). This column has 77% missing values.
- driveValue: A calculated metric representing the best performance-to-price ratio (Disk Rating divided by Price). This column also has 77% missing values.
- priceperGB: The price per gigabyte in USD ($). This column has 77% missing values.
- testDate: The calendar date when the drive's first benchmark submission was recorded.
- samples: The total number of individual benchmark samples collected for the model.
Distribution
The structure is tabular, contained within a CSV file named
SSD_HDD_benchmarks_v9.csv, which has a file size of 491.83 kB. The dataset contains 10 columns and 8927 records are valid for performance and date-related fields. It should be noted that the pricing-related fields (price, driveValue, and priceperGB) are largely incomplete, with only 2079 valid entries (23% of the dataset).Usage
This data is perfectly suited for several applications, including:
- Hardware Evaluation: Benchmarking the relative performance of diverse storage solutions.
- System Building: Assisting consumers and enthusiasts in selecting optimal storage components when building or upgrading a PC.
- Data Analysis: Utilisation in regression models to predict performance based on drive specifications.
- Trend Analysis: Comparing and modelling the evolution of storage technology performance over time.
Coverage
The data includes benchmark submission dates spanning from the year 2008 up to May 4th, 2022. The scope covers the performance characteristics of both Solid State Drives and traditional Hard Disk Drives across this 14-year period. No specific geographic or narrow demographic constraints are noted.
