Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T. or SMART) is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs). [3] Its primary function is to detect and report various indicators of drive reliability, or how long a drive can function while anticipating imminent hardware failures. [4] [5]

The internal storage of the PlayStation 5 is a custom-built 825 GB solid-state drive (667 GB available) [61] with a 12-channel interface, achieving a raw throughput of 5.5 GB/s. This atypical drive size was found to be optimal for the 12-channel pathway rather than a more common 512 GB or 1 TB unit.

On Apple Mac computers using Intel x86-64 processor architecture, the EFI system partition is initially left blank and unused for booting into macOS. [13] [14]However, the EFI system partition is used as a staging area for firmware updates [15] and for the Microsoft Windows bootloader for Mac computers configured to boot into a Windows partition using Boot Camp.
[4] [5] As part of the deal, Western Digital agreed to trade assets with Toshiba, with Toshiba receiving assets for the production of 3.5-inch hard drives (1, 2 and 3-platter drives produced in Shenzhen, China), in exchange for a Toshiba factory in Thailand for producing 2.5-inch drives (which had been inactive since the 2011 floods).

The SAS is a new generation serial communication protocol for devices designed to allow for much higher speed data transfers and is compatible with SATA. SAS uses a mechanically identical data and power connector to standard 3.5-inch SATA1/SATA2 HDDs, and many server-oriented SAS RAID controllers are also capable of addressing SATA hard drives.
