Western Digital has revealed plans to increase hard drive capacities to 140 TB and beyond by the 2030s through innovations like heat-assisted magnetic recording (HAMR) technology and 14-platter designs. The company will start producing commercial HAMR drives next year, with capacities expected to reach 60TB in 2028. Western Digital has developed a new vertical-emitting laser technology to improve areal density and increase platter capacity. Additionally, the company is working on a 12-platter platform for 60TB drives and anticipates offering 100TB HDDs by 2029-2030. Dual-actuator HDDs with enhanced performance capabilities are also in development.

Pirate RPG game is secretly looting your SSD lifespan — new Windrose patch promises smoother sailing and addresses excessive disk writing

The Windrose RPG game has been criticized for excessively writing to SSDs, potentially shortening their lifespan. The game's new patch aims to reduce disk usage significantly, addressing the issue of up to 108GB per hour being written to SSDs. Comparisons with other games like Enshrouded and Valheim show Windrose's disproportionate SSD resource consumption. The game's high storage demand is attributed to its save system design, which has been adjusted in the latest patch to improve write speeds by 60-75%. Players are advised to update to the latest version to mitigate potential SSD wear and tear.

Seagate FireCuda X Vault (8TB) review: A USB-powered, RGB-lit hard drive aimed at gamers

The Seagate FireCuda X Vault is a USB-powered 3.5-inch hard drive available in 8TB and 20TB options, designed for gamers with RGB lighting. It offers faster speeds than portable hard drives, around 200 MB/s in real-world tests, and includes two years of data recovery service. The drive has a plastic design with cooling fins and RGB lighting controls through Seagate's Toolkit software. While it outperforms smaller drives, it is slower than SSDs but comes at a more affordable price point. The drive's primary convenience is its single USB-C cable for power and data access, though users may need to consider available USB-C ports for power requirements.
