When the first computers were made, the information needed to run them was on punch cards. The computing device would decode the patterns on the punch cards and translate it to an action. It wasn’t until 1956 that IBM came up with the first magnetic hard drive, and floppy discs… » hackernoon.com | hackernoon.com
Over the past decade, solid-state drives (SSD) have brought about a new way of managing storage. » Alan Formy-Duval | opensource.com
Imgur user smellystring has officially changed my view of Minecraft – and he’ll change yours as well. Below is a fully functional 1KB hard drive, created within Minecraft and it’s incredible. Smellystring walks us through the process which includes binary blocks, pistons, a data collection room, indicator lights and ”bit” emulators. Watch and learn. » reddit.com » | imgur.com » Steven Norris | gearburn.com
FreeNAS es un sistema operativo basado en FreeBSD pero orientado a servicios de almacenamiento en red. NAS corresponde a las siglas de ”almacenamiento conectado en red”. FreeNAS y su fork Nas4Free son gratuitos, Nas4Free es open-source basado en licencia BSD. Estos sistemas operativos permiten crear un servidor doméstico muy potente con multitud de opciones de configuración como por ejemplo administración de decenas de usuarios con los permisos adecuados, crear unidades RAID para hacer copias de seguridad redundantes o aumentar el rendimiento del sistema. ...
MDADM (Multiple Device Administrator) es un conjunto de herramientas que son utilizadas en GNU/Linux para la gestión de RAID (Redundant Array of Independent Disks, que se traduce como conjunto redundante de discos independientes) administrado a través de software, distribuido bajo los términos de la Licencia Pública General de GNU versión 2 (GNU/GPLv2). » Joel Barrios Dueñas | alcancelibre.org
Linux kernel developer Theodore ”Ted” Ts’o has released a series of patches for what he has called ”a Lance Armstrong bug” in the kernel, meaning behaviour that does not trip up tests but nevertheless makes the kernel work differently than intended. A user had reported a problem that caused data loss; the kernel developers quickly narrowed this down to a fault in the ext4 implementation that was introduced with the release of Linux 3.6.2 just over a week ago. Apparently, the data corruption bug was hard to track down as it only manifests itself if a system is rebooted twice in a relatively short period of time. ...
NAND flash memory-based storage devices, such as SSD, eMMC, and SD cards, have been widely being used for ranging from mobile to server systems. Since they are known to have different characteristics from the conventional rotational disks, a file system, an upper layer to the storage device, should adapt to the changes from the sketch. F2FS is a new file system carefully designed for the NAND flash memory-based storage devices. We chose a log structure file system approach, but we tried to adapt it to the new form of storage. Also we remedy some known issues of the very old log structured file system, such as snowball effect of wandering tree and high cleaning overhead. Because a NAND-based storage device shows different characteristics according to its internal geometry or flash memory management scheme aka FTL, we add various parameters not only for configuring on-disk layout, but also for selecting allocation and cleaning algorithms. ...
