    Server Description

    A storage-optimized ARM64 instance pairing a dedicated single-core processor with a high-capacity 937 GB local NVMe SSD for localized data workloads.

    Storage & DatabaseMemory Optimized

    Amazon Web Services is4gen.medium is a storage-optimized instance utilizing a single-core AWS Graviton Neoverse-N1 ARMv8 processor running at 2.5 GHz. Built on the Nitro hypervisor, it features 6.0 GB of memory and a substantial 937 GB local NVMe SSD. While its single-core CPU performance is average, multi-core and memory bandwidth benchmarks fall into the lower percentiles, with large-block memory read speeds at 19.51 GB/sec and write speeds at 9.76 GB/sec. The instance delivers a baseline network bandwidth of 2 Gbps and supports hardware-accelerated AES cryptography. Given its high storage-to-compute ratio and moderate memory allocation, the is4gen.medium is qualitatively cost-effective for storage-heavy, low-compute workloads. It is best suited for lightweight databases, distributed caching, and localized file processing where high capacity local NVMe storage is prioritized over raw processing power.

    Workload Profiles

    0.103Score
    Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
