About this deal
n) HiSMRFs research file system for SMR: 2014, https://www.researchgate.net/public...rmance_file_system_for_shingled_storage_array
Seagate has formally introduced a new family of hard drives in the 2.5” form-factor. It is designed for laptops as well as external storage solutions. The new BarraCuda HDDs are based on 1 TB shingled magnetic recording platters and Seagate’s multi-tier caching technology. They enhance the maximum capacity of the company’s 2.5” HDDs to 5 TB - making the BarraCudaST5000LM000 the world’s highest-capacity 2.5” hard drive. When it comes to data recovery one of the most common problems Seagate ST2000LM015 Hard Disk Drive experience is burnt circuit board(PCB). So if you will need to match a replacement PCB, it is important that you note the “ Board Number” of your current circuit board in addition to the hard drive’s “ Model Number“.Toshiba's list of DM-SMR drives: https://toshiba.semicon-storage.com/ap-en/company/news/news-topics/2020/04/storage-20200428-1.html
If newer firmware is available for your drive, it will reflect the improvements we have engineered for the latest manufacturing. Firmware for legacy products will be the final release from manufacturing. Please note that Seagate does not offer details about specific firmware.l) OpenZFS Office Hour discussion on SMR: 2015, SMR, Resilvering, Possible Solutions at around 20, 31 and 46 mins respectively, https://youtu.be/mS4bfbEq46I?t=1220 SMR has worse sustained write performance than CMR, which can cause severe issues during resilver or other write-intensive operations, up to and including failure of that resilver. It is often desirable to choose a CMR drive instead. This thread attempts to pull together known SMR drives, and the sources for that information. SMR allows vendors to offer higher capacity without the need to fundamentally change the underlying recording technology.
