![]() The worst performer by far was the NTFS-3g driver for Linux NTFS read and write support. Performance issues & which disk file system to use?Īs a non-scientific test, back in 2013 I took a 4GB video file and copied it to various file systems using a Model B (Gen1) Raspberry Pi and the USB hard drive. I will call my mount point,usbdrive but first, we need to create it. These directories are known as mount points and can be given any name that works for you but they should be placed in /mnt. Linux recognises it and assigns a directory where you can access its content. When a hard drive is mounted, it connects to your Pi. For me, this caused interference where the hard drive would momentarily lose power. I would also recommend against powering the Raspberry Pi off the same USB Hub as a USB drive. My little Logitech ‘Premium 4-port’ USB hub can share 2.5A between 4 devices which is more than enough to power my Samsung (0.85A) drive. Attach the hub device to the Pi’s USB port, plug the USB hard drive into one of the hub’s ports and insert the hub’s power supply into a walled power socket. To get around this problem you need a powered USB hub. Unfortunately, the Pi cannot power some external drives. Many modern desktop PCs and laptops supply a higher amperage than the 0.5A specification to their USB ports to support devices such as portable hard drives. My old Samsung G2 Portable 640 hard drive requires 0.85A to work which is +0.35A above the USB2 specification. The Universal Serial Bus specification states that to adhere to the standard up to 0.5A (amps) can be drawn from a single port. USB power problemsĪ significant limitation for running a USB drive on a Raspberry Pi is the power requirements. A cheap USB powered external drive with many times more space can be had for a similar price to a top capacity SD memory card. SD memory cards are cheap and popular with low-end specifications but reach an affordability and storage cap when their sizes increase. But one of its limitations is the storage options if you wish to use the machine as a file or multimedia server. The Raspberry Pi is a great and flexible little device.
