IOPS (Input/Output Operations Per Second) is a key metric for evaluating storage performance in hard disks (HDD) and solid state drives (SSD). It is crucial for web hosting, virtual servers (VDS), and dedicated servers (Dedicated) as it affects the system's processing speed and overall performance.

IOPS measures the number of I/O operations a storage device can perform in one second, typically a read or write of a data block.


On servers, IOPS determines how quickly the server can read and write data, which is essential for high-performance applications like large databases or corporate websites. SpaceCore offers no limits on IOPS for virtual and dedicated servers, allowing full utilization of drives without restrictions.

There are no limits on the number of IOPS on virtual and dedicated servers from SpaceCore. This allows you to use the drives to the fullest without artificial restrictions.

Impact on IOPS

  • Disk Speed: SSDs provide much higher IOPS compared to HDDs.

SpaceCore uses only SSD and NVMe drives for virtual servers, having phased out HDDs for VDS/VPS.

  • Data Block Size: Larger data blocks can reduce IOPS due to longer processing times per operation.

  • Command Queue: The depth of the command queue, or the number of operations waiting to be processed, also affects IOPS.

IOPS is a critical performance indicator for storage systems, influencing the speed and performance of all server types.
