The difference between SSD and SDD

This is an introduction to SSDs.

The advantages of SSDs over most of today's HDDs are:

Stable! Store and gamble fast, much faster! The latency is minimal.

Quick start-up. No disk fragmentation is generated.

No noise. Because there is no mechanical motor and fan, the noise level is 0 dB when working. Some high-end or high-capacity products are equipped with fans, so they still generate noise.

No mechanical failures will occur, operating over a wider temperature range,:

A typical hard drive can only work in the range of 5 to 55. While most SSDs can work at -10 70, some industrial-grade SSDs can also operate in the -40 85 or even larger temperature range (:).

Runcore military-grade products have a temperature of -55 135).

Small size and light weight.

Low-capacity SSDs are smaller and lighter than HDDs of the same capacity. However, this advantage gradually diminishes as the capacity increases. Up to 256GB, SSDs are still lighter than HDDs of the same capacity.

Shock-resistant. Compared to traditional hard drives, SSDs are much more resistant to shocks, making data more secure.

All of the above are pros.

Cons: Expensive. It's expensive. Death is expensive.

You may have a misunderstanding, have you ever used a USB flash drive? The data carrier of the USB flash drive is Flash, and the same SSD is made of Flash.

Flashdisk,The advantage is that the speed is fast,The disadvantage is that the multiple read and write life of the same point is concentrated and reduced,The other is **high,A piece of 32G is thousands。 In addition, there is a high-speed hard drive. Commonly known as "electronic disk", it is composed of memory sticks or memory particles, which are identified as ordinary hard disks in the operating system, South Korea's Daikin's Jetspeed series products are composed of memory modules, the advantage is that the speed is very fast, faster than SSD, the disadvantage is that the data cannot be saved after power failure, the power consumption is large, and the **odd height is several times that of SSD.

The differences between SSD (Solid State Drive) and HDD (Hard Disk Drive) are as follows:

1. The storage principle is different

All the platters in the HDD are mounted on a rotating axis, each platter is parallel to each other, there is a head on the storage surface of each platter, the distance between the head and the platter is smaller than the diameter of a hair, all the heads are connected to a head controller, and the head controller is responsible for the movement of each head.

Solid-state drives (SSDs) are hard disks made from solid-state electronic memory chip arrays.

2. The shock resistance and drop resistance are different

Mechanical hard disks are all disk type, and the data is stored in the disk sector, which has poor shock and drop resistance.

SSDs are made of flash memory chips, so there are no mechanical parts inside the SSD, even if it is moved at high speed or even when it is accompanied by flipping and tilting, it will not affect normal use, and the possibility of data loss can be minimized in the event of collisions and **.

3. The data storage speed is different

Judging from the evaluation data, the performance of SSDs is more than 2 times higher than that of HDDs.

4. The noise level is different

Solid-state drives (SSDs) have no mechanical parts and flash memory chips, and have the characteristics of low heat generation, fast heat dissipation, and an operating noise level of 0 decibels. Mechanical hard disk drives (HDDs) generate a lot of heat and noise because of the mechanical motors and fans involved in the work.

Hello dear, GSSD refers to the solid state drive, this is a new type of hard disk, the performance is stronger, G refers to the capacity of the SSD for how many burns stool G. At present, ** is also quite high in laughing socks. A solid state disk (SSD) is a computer storage device that mainly uses NAND flash as permanent memory.

Differences: Solid-state drives are composed of control units and storage units (flash chips, DRAM chips), which are widely used in many fields such as industrial control, first-class monitoring, network monitoring, network terminals, and bump navigation equipment. The physical composition of SSD is basically flash memory + main control + cache + PCB + interface, there are no mechanical parts, data reading and writing are electronic signals, there is no bottleneck factor such as motor speed, and the performance will naturally come up.

SSDs are solid-state drives, or solid-state drives for short. HDD is a mechanical hard disk, SSD is different from HDD in that SSD does not have motors, platters, head rocker arms and other mechanical parts, SSD saves the time of mechanical parts movement compared to HDD, so its data transmission speed is much faster than HDD. <

Demo model: Lenovo Tianyi 510S System version: Win10 SSD is a solid state drive, referred to as a fixed disk.

HDD is a mechanical hard disk, SSD is different from HDD in that SSD does not have motors, platters, head rocker arms and other mechanical parts, SSD saves the time of mechanical parts movement compared to HDD, so its data transmission speed is much faster than HDD.

SSD and HDD are better than SSD hard drives.

A typical SSD is flash memory based on NAND technology, which is a type of non-volatile memory. What does non-volatility mean? The answer is that if Qingxun is stopped from running the hard disk, the content of the bad reputation stored in it will not be lost. This is, of course, an essential feature of any type of permanent memory.

In the early days of SSD drives, there were suspicions that the data stored would expire after a few years, but today's technology has shattered this myth because people can read and write data frequently on the SSD drive for a long time, and the data storage integrity will still be preserved for more than 200 years. In other words, SSDs can store data longer than humans!

What is the difference between SSD and HDD:

1. SSDs are more secure than HDDs because they don't move.

The arm of the hard drive can move less than 10 nanometers above the disk. This allows us to access the data quickly and makes the hard drive small enough.

2. SSDs can load and save data faster than HDDs.

While security is good, the biggest advantage of SSDs is speed. SSDs are much faster than most HDDs, which makes them an excellent choice for multitasking.

3. SSDs are worth the money.

Whatever your needs, when you need to store your data somewhere. Solid-state drives are a very good option with few drawbacks. They're faster and safer in everyday use, and when combined with a traditional hard drive, can really help you get the most out of your setup.

1. The storage unit is different

The SSD storage unit is a solid-state electronic memory chip array.

HDD storage units are disk-type platters.

2. Different weight: SSDs are lighter in terms of weight, 20-30 grams lighter than conventional inch hard drives.

3. Different noise: Since SSD SSDs have no mechanical parts and flash memory chips, the working noise value is 0 decibels.

HDD HDDs have mechanical motors and fans, and there will be noise during working conditions.

4. The service life is different

SSDs have a lifetime of 100,000 reads and writes.

HDD HDD has a read/write life of only 10,000 times.
