A solid-state drive (SSD, also known as a solid-state disk) is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology primarily uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives (HDDs), which permit simple replacements in common applications. New I/O interfaces like SATA Express and M.2 have been designed to address specific requirements of the SSD technology.
SSDs have no moving mechanical components. This distinguishes them from traditional electromechanical magnetic disks such as...
Flash memory is an electronic (solid-state) non-volatile computer storage medium that can be electrically erased and reprogrammed.
Toshiba developed flash memory from EEPROM (electrically erasable programmable read-only memory) in the early 1980s and introduced it to the market in 1984. The two main types of flash memory are named after the NAND and NOR logic gates. The individual flash memory cells exhibit internal characteristics similar to those of the corresponding gates.
Where EPROMs had to be completely erased before being rewritten, NAND-type flash memory may be written and read in blocks...
In electronics, a multi-level cell (MLC) is a memory element capable of storing more than a single bit of information.
MLC NAND flash is a flash memory technology using multiple levels per cell to allow more bits to be stored using the same number of transistors. In single-level cell (SLC) NAND flash technology, each cell can exist in one of two states, storing one bit of information per cell. Most MLC NAND flash memory has four possible states per cell, so it can store two bits of information per cell. This reduces the amount of margin separating the states and results in the possibility of more...
Write amplification (WA) is an undesirable phenomenon associated with flash memory and solid-state drives (SSDs) where the actual amount of information physically written to the storage media is a multiple of the logical amount intended to be written.
Because flash memory must be erased before it can be rewritten, with much coarser granularity of the erase operation when compared to the write operation, the process to perform these operations results in moving (or rewriting) user data and metadata more than once. Thus, rewriting some data requires an already used portion of flash to be read, updated...

The Apple A10 Fusion is a 64-bit system on a chip (SoC), designed by Apple Inc. and manufactured by TSMC. It is the fastest single-threaded mobile SoC released to date, and first appeared in the iPhone 7 and 7 Plus which were introduced on September 7, 2016. The A10 is the first Apple-produced quad-core SoC, with two high-performance cores and two energy-efficient cores. Apple states that it has 40% greater CPU performance and 50% greater graphics performance compared to its predecessor, the Apple A9.

The A10 with a die area of 125 mm2, 3.3 billion transistors (including the GPU and...
As part of a bash script, I need to send a huge number (between 90,000 and 100,000) of json post requests over the same connection to a server which supports http/2 and pipelining
Which is the command I need to use for that?
Wil's answer is vaguely correct, but isn't technically accurate. Yes, a drive does not need an MBR. Without one, you will be unable to boot from that drive, and you will not be able to create partitions on that drive. BUT...
The term Master Boot Record is often used to refer to two things -- ...
