The hard disk throughput capacity of big data cloud server instances refers to the amount of data that can be read from or written to the disk per unit of time, typically measured in megabytes per second (MB/s) or gigabytes per second (GB/s). This capacity depends on factors such as the type of storage (e.g., HDD, SSD, or NVMe), the disk's interface (e.g., SATA, SAS, or PCIe), and the instance's configuration.
For example, a big data cloud server instance with SSD storage might offer a throughput of 300 MB/s to 500 MB/s for sequential reads and writes, while an NVMe-based instance could achieve significantly higher throughput, often exceeding 2 GB/s.
In Tencent Cloud, big data workloads can leverage high-performance storage options like CBS (Cloud Block Storage) with SSD or Premium SSD, which provide high throughput and low latency. For even higher performance, Tencent Cloud offers local SSDs or NVMe-based storage solutions, ideal for scenarios requiring rapid data processing, such as real-time analytics or distributed computing.
