A hybrid drive (solid state hybrid drive – SSHD, and dual-storage drive) is a logical or physical computer storage device that combines a faster storage medium such as solid-state drive (SSD) with a higher-capacity hard disk drive (HDD). The intent is adding some of the speed of SSDs to the cost-effective storage capacity of traditional HDDs.
For most disks, each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs), and 2048 bytes for CD-ROMs, DVD-ROMs and BD-ROMs. [1] Newer HDDs and SSDs use 4096 byte (4 KiB) sectors, which are known as the Advanced Format (AF). The sector is the minimum storage unit of a hard drive. [2]
114 minutes of uncompressed CD-quality audio at 1.4 Mbit/s is approximately 1 GB. A single-layer DVD+R disc can hold about 4.7 GB. A dual-layered DVD+R disc can hold about 8.5 GB. A single-layer Blu-ray can hold about 25 GB. The largest Nintendo Switch cartridge available on the market holds about 32 GB. A dual-layered Blu-ray can hold about 50 GB.
The S-IVB evolved from the upper stage of the Saturn I rocket (the S-IV) and was the first stage of the Saturn V to be designed. The S-IV used a cluster of six RL-10 engines but used the same fuels as the S-IVB – liquid hydrogen and liquid oxygen.
A SIV may be thought of as a very simple virtual non-bank financial institution (i.e. it does not accept deposits). Instead of gathering deposits from the public, it borrows cash from the money market by selling short maturity (often less than a year) instruments called commercial paper (CP), medium term notes (MTNs) and public bonds to professional investors.
GigaDevice GD32F103CBT6 ARM Cortex-M3 based microcontroller die. The GD32 series of microcontrollers are based on the ARM Cortex-M3 core. It was introduced in 2013 and consists of six product lines: Basic, Mainstream, Value, Connectivity, Performance, and Extend.
