Ethereum needs solid state drive

Solid state hard disk is generally used to install the system, and large capacity solid state hard disk can also be used to store data and files

because of its small size and light weight, solid state hard disk occupies a very small space in the chassis, which can be ignored compared with the heavy mechanical hard disk

extended data

advantages of solid state disk:

1, fast reading and writing speed

flash memory is used as the storage medium, and the seek time is almost zero, so the reading speed is fast

2, shockproof and anti dropping performance

solid state hard disk is made of flash memory particles, and there are no mechanical parts inside, so even in the case of high-speed movement or even with overturning and tilting, it will not affect the normal use

3, low power consumption, no noise

because there is no mechanical motor and fan, the noise value of SSD is 0 dB when it works, and the heat generation is small and the heat dissipation is fast

4, wide temperature range

most SSDs can work at - 10 ~ 70 ℃, and their chips have a wider temperature range (- 40 ~ 85 ℃)

5, lightweight

SSD is very light in weight, compared with the conventional 1.8-inch hard disk, the weight is 20-30g lighter

Solid state drives, referred to as solid disk, are made of solid state electronic memory chip array, which are composed of control unit and memory unit (flash chip, DRAM chip). The interface specification, definition, function and using method of solid state hard disk are the same as that of ordinary hard disk, and the proct appearance and size are also the same as that of ordinary hard disk. It is widely used in military, vehicle, instrial control, video monitoring, network monitoring, network terminal, power, medical, aviation, navigation equipment and other fields

Yes, the advantages of SSD are booting the system, booting the software and entering the game. Read a large number of small files program speed is very fast, dozens of times faster than the mechanical hard disk hundreds of times. Therefore, the application software must be installed on the SSD to give full play to the advantages of SSD

if the software is still installed in the mechanical hard disk, because it still reads information from the mechanical hard disk when it starts up, the speed is not improved. It has nothing to do with whether there is a solid-state hard disk in the computer, so the speed of things in the ordinary hard disk is the same as before

extended data

if solid state hard disk and ordinary hard disk are used together, then the speed is different. You can set the solid state hard disk to be divided into one or several hard disk areas (such as C disk area, D disk area, etc.), and ordinary hard disk can also be divided into several hard disk areas (such as e disk area, f disk area, etc.)

if you install the system in the area of SSD (Disk C), the system will run very fast. For example, if you start the system for a few seconds, the speed of starting each software will also be accelerated. If you put the common software in the area of SSD (disk d), it will be even faster

and the software of ordinary hard disk is the same speed as the original one, which means that if you put a software in the area of SSD, it will be much faster. If you put it in ordinary hard disk, the speed is almost the same as the original one

for example, 120g solid-state + 500g ordinary disk, the system and online games are installed in solid-state disk (system installed C, game installed d), while other large-scale games or stand-alone games, Web caching, video caching, music files and so on are all placed in several areas of the ordinary hard disk

The analysis is as follows:

the capacity of hard disk mainly depends on the user's demand for the computer. For users who like to download a large number of resources, they will not use the computer reasonably. No matter how large the capacity of hard disk is, it will be useful when it is full. Generally, the installation of win8 / win7 system needs about 10g hard disk space. In addition, the installation of some commonly used applications generally needs about 5g-15g hard disk space

that is to say, for most ordinary users, the most basic system + installed applications will occupy about 20g of space, and there will be about 100g of remaining storage space for later use, which can be used later. At present, the popular storage mode is: solid state hard disk + traditional mechanical hard disk

judging from the Current Windows system, 256g SSD is enough to support the operation of the system. Using fixed state hard disk as system disk can improve system fluency

extended data:

the more SSD storage, the slower performance. If a partition is used more than 90% for a long time, the possibility of SSD crash will be greatly increased

therefore, it is very important to clean up the useless files in time, set the appropriate virtual memory size, and store the large files such as movies and music in the mechanical hard disk
