Calculators

Estimate how long a solid-state drive may last based on its endurance rating, daily write workload, spare area reserved, and workload type.

Calculate estimated usable storage capacity for a RAID array based on the number of drives, drive size, RAID level, and filesystem overhead.

Estimate the usable capacity remaining after reserving spare area for SSD overprovisioning, based on total drive capacity, existing used space, desired overprovisioning percentage, and the drive’s decimal-to-binary capacity factor.

Estimate the total usable storage required after accounting for redundancy overhead and reserve capacity, based on your raw data size, redundancy method, growth buffer, and backup retention copies.

Estimate the usable NAS storage capacity after RAID overhead and reserve space based on drive count, drive size, RAID level, and reserved free space percentage.

Estimate usable storage capacity for a RAID 10 array based on the number of drives, drive size, reserved spare drives, and filesystem overhead. RAID 10 mirrors half of the available drives, so usable capacity is approximately half of the non-spare raw capacity after overhead.

Calculate the usable storage capacity of a RAID 6 array after dual-parity overhead, based on the number of drives, drive size, unit conversion, and filesystem overhead reserve.

Calculate the usable storage capacity of a RAID 5 array based on the number of drives and the capacity of each drive. RAID 5 uses the equivalent of one drive for parity, so usable capacity equals the capacity of the smallest drive multiplied by the number of drives minus one.

Calculate the usable storage capacity of a RAID 1 array based on the number of drives, drive size, filesystem overhead, and reserved free space. RAID 1 mirrors data, so usable capacity is based on a single drive’s effective capacity rather than the total raw capacity.

Calculate the usable storage capacity of a RAID 0 array based on the number of drives, drive size, formatting convention, and reserve space. RAID 0 stripes data across all drives with no redundancy, so usable capacity is the sum of all drive capacities minus any reserved percentage.

Estimate the usable SSD storage capacity needed based on operating system space, applications, games, media files, and free space reserve.

Calculate effective memory data rate and theoretical memory bandwidth from memory clock, transfer mode, bus width, and channel count.

Estimate usable storage capacity after accounting for drive size, number of drives, RAID overhead, filesystem reserve, and decimal-to-binary conversion.

Estimate required disk space based on number of files, average file size, redundancy level, operating system overhead, and growth buffer. Useful for planning storage needs for personal, business, or server use.

Estimate total PC storage capacity needed based on operating system files, installed applications, games, media files, and a free space buffer for performance and future growth.

Estimate recommended virtual memory (page file) size based on installed RAM, workload intensity, concurrent heavy applications, and storage type. The calculation provides a practical recommended size for total virtual memory allocation in GB using a base RAM multiple with workload and concurrency adjustments.

Estimate the total file size of a web page based on images, scripts, stylesheets, fonts, and other assets. Useful for performance budgeting and page weight planning.

Estimate total RAM usage based on the number of browser tabs, applications, background processes, and the average memory used by each component.

Estimate recommended RAM capacity in GB based on operating system overhead, number of concurrent applications, browser tabs, workload intensity, and desired multitasking headroom.

Estimate the percentage performance improvement from enabling XMP based on current memory speed, XMP memory speed, memory capacity, workload type, and CPU memory sensitivity.

Calculate true RAM timing latency in nanoseconds from memory data rate and primary timing values. This helps compare kits by converting CL, tRCD, tRP, and tRAS into real-time latency.

Estimate theoretical memory bandwidth based on RAM data rate, memory bus width, channel count, and transfer efficiency. Useful for comparing DDR memory configurations in terms of peak and effective throughput.

Estimate first word latency for a voice or conversational AI system based on model inference time, network latency, prompt size, response streaming setup, and server load.

Calculate true memory latency in nanoseconds from CAS latency, data rate, memory type timing factor, and command rate.

Calculate true memory latency in nanoseconds from RAM data rate and CAS latency. Optionally include command rate overhead and compare DDR generations using effective transfer rate input.

Calculate true RAM first-word latency in nanoseconds from data rate, CAS latency, command rate, and memory generation. Useful for comparing DDR memory kits beyond marketed MT/s numbers.

Estimate theoretical peak memory bandwidth for a dual-channel RAM configuration using memory data rate, bus width per channel, number of channels, and an efficiency factor to reflect practical throughput.

Calculate theoretical memory bandwidth based on memory data rate, bus width, channel count, and efficiency. Useful for estimating RAM, GDDR, or HBM peak and effective throughput.

Calculate effective DDR memory data rate in MT/s from the memory clock, DDR generation multiplier, channel efficiency, and optional overclock factor. This helps estimate the advertised transfer rate based on double data rate signaling and practical tuning conditions.

Estimate effective RAM speed by adjusting the rated memory speed for memory channel configuration, command rate, and memory access pattern efficiency. This provides a practical throughput-oriented speed estimate rather than the advertised base MT/s value alone.
