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 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.

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 ...
The ReadyBoost cache is created on the root directory of the drive. If the system drive (the primary drive, with Windows system files on it) is a solid-state drive (SSD), ReadyBoost is disabled, since reading from that drive would be at least as fast as reading from the ReadyBoost drive. [7]
The block occupies a cache line in set 31, determined by the replacement policy for the cache. Address 0x0100 (tag – 0b000_0010, index – 0b0_0000, offset – 0b00) corresponds to block 64 of the memory and maps to the set 0 of the cache. The block occupies a cache line in set 0, determined by the replacement policy for the cache.
