What are the advantages of flash memory over hard disk storage?

The access time of the flash memory is about 1000 times faster than that of the hard disk. Flash can improve the performance of input / output-heavy applications. In particular, the database runs much faster than the hard disk.

Believe it or not, cost is also advantageous. In general, flash drives are much more expensive than hard drives, but you can measure costs using a variety of statistics if your business model relies on efficient execution of large volumes of transactions. With SSD, the $ / transaction cost is much lower than the hard drive. So the hard drive is "cheap", but in that use case the total transaction cost will be high

Solid state drives are more intensive. In other words, you can have a smaller 512 GB hard drive than chewing gum, making your laptop smaller and more efficient.

SSD usually consumes less power than a hard drive, but this can change if a large number of consecutive writes are done.

Some people argue that hard drives have durability benefits, but I disagree: SSD has a very predictable service life. I will not do a hard drive. They failed randomly and catastrophically. SSD wears little by little and warns that life will expire. Predictability may be a major advantage depending on the operational model, but hard drives are generally considered more reliable. I said SSD is more reliable.

Some say that the superiority of capacity is hard disk, but it is not so. Currently large capacity SSDs are being manufactured, far exceeding hard drives. Seagate's new 60 TB SSD is the world's largest

What are the benefits of RAM and flash storage on the hard disk? What are the main advantages of RAM for other kinds of storage devices?

RAM is the main storage area and can be addressed directly from the CPU. The CPU can expand and read and write to arbitrary place in the RAM. Only a certain amount of RAM can exist up to the limit that the CPU can solve.

Flash drives and hard drives are secondary storage devices. They are abstracted from the CPU. This storage can not be accessed directly. This data needs to be shuttled in memory (primary storage) for any purpose. From an amateur's point of view, the process is far from the CPU because it contains many processes.

"Fixed storage" of hard disk or flash. It is usually on a computer provided by a rotating hard disk (also called "hard disk") or "flash memory". While the flash memory is in "solid state", the hard disk reads and writes the magnetic pattern on the rotating metal disk, there are no moving parts and only the silicon chip stores bits. In either case, the storage is permanent to maintain its state even when the power is turned off. Flash (also called 'flash drive', usually usb key format) is as durable as hard drive, it is faster and consumes less power than hard drive. But each byte, flash is much more expensive than hard disk storage. Because the flash is cheap, you may occupy a niche at the expense of a hard drive. Since flash memory is much slower than RAM memory, it is not a substitute for RAM. (Adobe's "flash" has nothing to do, this is a proprietary media format.)

The file system's hard disk or flash provides persistent storage as a flat, unidentified byte set with no organizational structure. Typically, hard disks or flash memory are formatted using a "file system" that organizes bytes into familiar file and directory modes, each mode has a convenient name such as "resume-2010.txt" I will. . Basically, each file refers to a byte block, so the name "flowers.jpg" refers to a block of 48 KB bytes which is the data of that image. The file system actually provides the user with the name (possibly an icon) of the block of data bytes, allowing data manipulation such as moving, copying, opening in a program. The file system also tracks "meta information" about bytes. How many bytes are there when the last change
