These devices used a built-in hard disk for storage, with capacities of 60, 120, 160, and 250 GB; while the Archos 7 is available in 160 and 320 GB capacities and the Archos 5G is in 30 GB. Though similar to the Archos 5, the Archos 5G features 3.5G HSDPA wireless connectivity.
Due to typical file system design, the amount of space allocated for a file is usually larger than the size of the file's data – resulting in a relatively small amount of unusable storage space for each file, called slack space or internal fragmentation.
This was the first Seagate hard drive to use perpendicular magnetic recording (PMR) technology (only in 250 GB SATA models: ST3250410AS with 16 MB of cache and ST3250310AS with 8 MB of cache). Seagate announced launch of Barracuda 7200.10 on April 26, 2006. [33] 250 GB PMR models were launched on June 7, 2007. [34]
SSD benchmark, showing about 230 MB/s reading speed (blue), 210 MB/s writing speed (red) and about 0.1 ms seek time (green), all independent from the accessed disk location. Traditional HDD benchmarks tend to focus on the performance characteristics such as rotational latency and seek time. As SSDs do not need to spin or seek to locate data ...
This includes writing partition and file system structures into selected logical blocks. For example, some of the disk space will be used to hold a directory of disk file names and a list of logical blocks associated with a particular file. Examples of partition mapping scheme include Master boot record (MBR) and GUID Partition Table (GPT).
March 2011 saw the introduction of two new SSD lines from Intel. The first, the SSD 510, used an SATA 6 Gigabit per second interface to reach speeds of up to 500 MB/s. [14] The drive, which uses a controller from Marvell Technology Group, [15] was released using 34 nm NAND Flash and came in capacities of 120 GB and 250 GB. The second product ...
The terms partition table and partition map are similar terms and can be used interchangeably. The term is most commonly associated with the MBR partition table of a Master Boot Record (MBR) in PCs , but it may be used generically to refer to other formats that divide a disk drive into partitions, such as: GUID Partition Table (GPT), Apple ...
The Xbox 360 technical specifications describe the various components of the Xbox 360 video game console.. The console features a port on the top when vertical (left side when horizontal) to which a custom-housed hard disk drive unit can be attached in sizes of either 20, 60, 120, 250, 320, 500 GB; [1] and as of April 2015 all 2.5" SATA Hard Drives up to 2 TB, [2] [3] the user can use the ...
