Bélády's algorithm is the optimal cache replacement policy, but it requires knowledge of the future to evict lines that will be reused farthest in the future. A number of replacement policies have been proposed which attempt to predict future reuse distances from past access patterns, [23] allowing them to approximate the optimal replacement ...
Available in capacities between 250 GB to 3 TB, 7200 RPM, 16 MB to 64 MB cache, depending on the model. First Seagate hard drives with 1 TB [59] per platter technology. From this generation onwards, Seagate phased out previous "green" models, citing the inherent power saving functions featured on the 14th generation removed the need for a ...
ST3000DM001 as external hard drives in retail packaging. Anand Lal Shimpi of AnandTech noted that the ST3000DM001 is "a bit faster in sequential performance than the old Barracuda XT, at lower power consumption" and that "Seagate appears to have optimized the drive's behavior for lower power rather than peak performance".
In computing, cache algorithms (also frequently called cache replacement algorithms or cache replacement policies) are optimizing instructions—or algorithms—that a computer program or a hardware-maintained structure can follow in order to manage a cache of information stored on the computer. When the cache is full, the algorithm ...
Pseudo-LRU or PLRU is a family of cache algorithms which improve on the performance of the Least Recently Used (LRU) algorithm by replacing values using approximate measures of age rather than maintaining the exact age of every value in the cache. PLRU usually refers to two cache replacement algorithms: tree-PLRU and bit-PLRU.
In computer storage, a disk buffer (often ambiguously called a disk cache or a cache buffer) is the embedded memory in a hard disk drive (HDD) or solid-state drive (SSD) acting as a buffer between the rest of the computer and the physical hard disk platter or flash memory that is used for storage.
