2 System requirements
This topic highlights requirements to hardware and software that may be used to run Paragon
NTFS&HFS+ for Linux 9.5.
2.1 Hardware requirements
Minimum hardware requirements:
• Processor: Intel Pentium 300 MHz and higher, or compatible;
• both 32- and 64-bit CPUs are supported;
• 16MB of RAM.
Due to unique technology NTFS&HFS+ for Linux drivers have low system requirements. For example,
it is enough for our driver to have 650KB of free RAM to work with NTFS partitions larger than 250
GB. NTFS&HFS+ Kernel modules occupy around 800 Kb of RAM.
Real-life values:
• 200 Kb while executing 5 commands like ’dd if=/dev/zero of=/mnt/sda1/test bs=1M
count=1000&’ in background.
• 516 Kb while executing ’rsync -r /home /mnt/sda1’ command.
• 17 Mb while compiling bench test on Desktop Linux system in virtual environment using NTFS file
system: a file-tree with a size about 220 Mb was created and patched, simulating Linux Kernel
installation process.
RAM consumption depends first of all on whole amount of memory available in the system. If it is low
then the driver wouldn’t keep a lot of descriptors opened to keep the memory usage at minimum.
2.2 Software requirements
Supported Linux Kernel versions
• Linux with kernel versions 2.6.36 and newer;
• Linux with kernel versions up to 4.12.x (NTFS&HFS+ driver was tested with Kernels up to 4.12.5).
Linux distributions the products were tested with:
• Ubuntu 17.10;
• Debian 9.1;
• Fedora 26;
• OpenSuse 42.3;
• CentOS 7.
