The 500gb BarraCuda drives are likely discontinued as of late 2024 due to declining demand for lower capacity hdds. Now the 1tb model is the lowest capacity likely for 2.5 drives as well. 1Tb 3.5 models using CMR technology are ST1000DM010(released 2016) and the newer ST1000DMZ10(2018). All 2.5 models use SMR which can be slower.
Seagate started shipping device-managed SMR hard drives in September 2013, stating an increase in overall capacity of about 25% compared to non-shingled storage. [1] [11] In September 2014, HGST announced a 10 TB drive filled with helium that uses host-managed shingled magnetic recording, [12] although in December 2015 it followed this with a 10 TB helium-filled drive that uses conventional ...
The Westinghouse SMR design is a scaled down version of the AP1000 reactor, designed to generate 225 MWe. After losing a second time in December 2013 for funding through the U.S. Department of Energy's SMR commercialization program, and citing "no customers" for SMR technology, Westinghouse announced in January 2014 that it is backing off from ...
The small modular reactor (SMR) is a class of small nuclear fission reactor, designed to be built in a factory, shipped to operational sites for installation and then used to power buildings or other commercial operations. The term SMR refers to the size, capacity and modular construction. Reactor type and the nuclear processes may vary.
This TDMR approach is being applied to both shingled (SMR) and conventional PMR HDDs. [20] The gains achieved are quite modest (6 to 12%) but are expected to increase going forward as more complex schemes are implemented. [21]
NuScale's SMR designs employ 9 feet (2.7 m) diameter by 65 feet (20 m) high reactor vessels that use conventional cooling methods and run on low enriched uranium fuel assemblies based on existing light water reactor designs. Each module is intended to be kept in an underground pool and is expected to produce about 77 megawatts of electricity.
