Test and evaluation of Seagate SWD
摘要
Abstract
The advantages and limitations of the shingled magnetic recording (SMR) technique which can enhance the disk storage density were analyzed, and it was pointed that SMR adopts the way of partially overlapping adjacent tracks to increase the areal density of the disk, but this brings the write overlay problem, that is when updating a track's data, adjacent tracks' effect data can be covered, thus leading that the shingled write disk (SWD) can not support in-place update and the non-sequential writing performance can be affected.To promote the application of this SMR technique, the testing tools of Fio and Filebench were used to more comprehensively test the Seagate's shingled write disk (SSWD), a representative product of the SMR technique, and its performance in variety of application scopes was analyzed to privide useful references for SSWD's applications.关键词
