➀ Seagate's Exos M 30TB introduces HAMR technology, achieving a breakthrough 30TB capacity with 275MB/s sustained write speeds.

➁ The drive uses laser-heated media and Mozaic 3+ platform for higher storage density while maintaining power efficiency at 9.5W.

➂ Priced at $20/TB, it targets enterprise users but faces competition from smaller drives, with SMR variants reaching up to 36TB.

➀ Seagate's 28TB Expansion external hard drive integrates HAMR (Heat-Assisted Magnetic Recording) technology, offering high-capacity storage in a compact design with USB 3.2 and external power support;

➁ Opening the enclosure reveals a Seagate Barracuda 28TB HAMR drive, typically not sold separately and possibly rebadged from enterprise-grade Exos or IronWolf Pro HDDs;

➂ Shucking the external drive provides significant cost savings ($240 less than standalone 28TB HDDs), though sacrificing warranty coverage.

➀ Western Digital reaffirms plans to begin mass production of 36TB HAMR HDDs in 2027, alongside 40TB SMR and 44TB UltraSMR variants.

➁ A final generation of ePMR2-based HDDs, including a 36TB UltraSMR model, will launch in 2024 as a transitional product.

➂ Seagate has already shipped 36TB HAMR drives, securing an early lead, while Toshiba's HAMR roadmap remains undisclosed.

➀ This research investigates how metallic thin films, specifically cobalt layers used in hard disk drives (HDDs), can be modified to improve performance and reliability through plasma-assisted surface modification techniques.

➁ The study uses molecular dynamics (MD) simulations and experimental validation to demonstrate how different inert gas ions affect asperity size and surface texture.

➂ The findings suggest that heavier inert gas ions are more effective at reducing asperity size, with Xenon (Xe) providing the most pronounced smoothing effect.

➀ The newly imposed U.S. import duties are likely to significantly increase the cost of storage devices due to their impact on HDD and SSD manufacturers.

➁ HDD manufacturers like Seagate, Toshiba, and Western Digital have complex supply chains with production in various countries, making them susceptible to high tariffs on Chinese-made drives.

➂ SSD manufacturers face challenges due to the 'country of origin' rules, potentially leading to increased costs if they are not assembled in countries exempt from tariffs.

➀ Today marks World Backup Day, a day to remind everyone to regularly back up their important data to prevent data loss;

➁ The article highlights various storage deals available during the Amazon Big Spring Sale, including SSDs, HDDs, and portable storage options;

➂ It provides details on specific deals, such as the Samsung 990 Pro 4TB SSD and Seagate IronWolf Pro 24TB HDD, along with their original and discounted prices.
