![]() ![]() As the cache fills up, the least hot files will retire from NAND to make room for more data while the original files remain accessible from the disk media if needed. Subsequent requests for this data by the host can then be fulfilled far faster from flash memory than from rotating magnetic platter (media/disk). Hot data gets copied from magnetic media into NAND cache.At the very least, TurboBoost can help to improve general work productivity through greatly improved availability of hot data (the data most frequently sought by the host) and greatly reduced IOPS response time. Rather than constructing storage solutions with a mixture of discrete HDDs and SSDs, TurboBoost can often provide the best of both worlds. This new 512e drive integrates small amount of eMLC NAND as cache, reducing latencies for significantly faster, predictable response times. ![]() TurboBoostTM (trademark of Seagate Inc) Enhanced Cache was Seagate’s major performance enhancement to standard enterprise performance HDD design (10K & 15K RPM rotational speed). In late April 2017, Dell has introduced a new 2.5” form factor 900GB 15K 512e 12Gbps SAS HDD with Enhanced Cache to boost Read performance in addition to the Advance Write Cache that comes standard in this family.
