Designed for use in RAID or NAS arrays with 1 to 8 drive bays, the 4TB N300 7200 rpm SATA III 3.5" Internal NAS HDD from Toshiba meets the reliability, performance, endurance, and scalability requirements of 24/7 NAS applications for personal, home office, and small business use. This 4TB drive operates using a SATA III 6 Gb/s interface, a 512MB cache, and a rotational speed of 7200 rpm, all of which help to ensure uninterrupted data transfers with a rate of up to 281 MB/s. This drive also features high levels of reliability, with 600,000 load/unload cycles, 1 in 10¹⁵ non-recoverable read errors per bits read, a workload rate of up to 180TB per year, and a 1 million hour MTTF. Shock protection is provided by a rotational vibration sensor, while ramp loading helps reduce wear and Error Recovery Control limits recovery time to help optimize error correction.

Q: 4. I’m a professional photographer and all of my images are stored via these large drives. My operating system is on a ssd, and when I first bring images in they are processed on my ssd drive. But one I store them, they are still accessed by my software (Lightroom and other Adobe products), and often I’m still retrieving, searching for and editing the images long after they were moved off my ssd drive.
