Is there an SSD and what does an SSD look like

SSDs are generally not necessary, they are luxuries, not necessities. Replacing an SSD is only for the sake of being faster, not necessary.

SSDs are many times faster than HDDs in terms of 4K performance, dramatically reducing the time it takes to boot up the system and software. But the same thing can be done with a mechanical disk, but for a longer time. Therefore, the role of SSDs is only to increase speed, and the function is the same as that of HDDs, not irreplaceable.

Solid state drives, referred to as solid state drives, are hard disks made of solid-state electronic memory chip arrays, which are composed of control units and storage units (flash chips, DRAM chips). SSDs are identical to HDDs in terms of interface specifications and definitions, functions and usage methods, and are also completely consistent with HDDs in terms of product shape and size. It is widely used in military, vehicle, industrial control, ** monitoring, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and other fields.

The operating temperature range of its chips is very wide, commercial products (0 70) and industrial products (-40 85). Although the cost is higher, it is gradually becoming popular in the DIY market. Because SSD technology is different from traditional hard disk technology, many new memory manufacturers have emerged.

Manufacturers only need to buy NAND memory, and then cooperate with the appropriate control chip, and then they can make SSDs. The new generation of SSDs generally uses SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, NGFF interface, CFast interface and SFF-8639 interface.

Whether it is a notebook or a desktop, solid-state drives have become standard, when buying solid-state drives, the quality, performance, ** and other factors of the product must be considered When buying a computer, you will choose a 120g solid state drive, many people will ask me if 120g is enough, in fact, it is enough, because the solid state drive is mainly to install the system, so it will be when it is turned on.

SSD:There are two types of storage media for <> SSDs, one is to use flash memory (flash chip) as the storage medium, and the other is to use DRAM as the storage medium. Also the latest is Intel's XPoint particle technology.

Basic structure. Flash-based SSDs are the main category of SSDs, and their internal structure is very simple, the main body of the SSD is actually a PCB board, and the most basic accessories on this PCB board are the control chip, the cache chip (some low-end hard disks have no cache chip) and the flash memory chip used to store data.

Main control chip. The more common SSDs on the market are LSISANDFORCE, INDILINX, JMowron, Marvell, Phison, Sandisk, Goldendisk, Samsung, Intel and other main control chips. The main control chip is the brain of the SSD, and its role is to reasonably allocate the load of data on each flash memory chip, and the second is to undertake the entire data relay, connecting the flash memory chip and the external SATA interface.

There is a big difference in the ability between different masters, and there will be great differences in data processing capabilities, algorithms, and read and write control of flash memory chips, which will directly lead to a gap of several times in the performance of SSD products.

Solid state drive (solid state disk or solid state drive, abbreviated as SSD), commonly known as solid state drive.

Solid-state drives are hard disks made with an array of solid-state electronic memory chips.

It is named because solid capacitors are called solid in Taiwanese English. The SSD consists of a control unit and a memory unit (flash chip, DRAM chip).

SSDs are identical to ordinary HDDs in terms of interface specifications and definitions, functions and usage methods, and are basically the same as HDDs in terms of product shape and size (the size and shape of SSDs in the emerging form are completely different from SATA HDDs).

The operating temperature range of the chip is very large, commercial products (0 70) and industrial products (-40 85). Although the cost is high, it is becoming more popular in the DIY market.

Because the technology of solid-state drives is different from that of traditional hard disks, many new memory manufacturers have emerged. Manufacturers only need to buy NAND chips, then configure the appropriate control chip, write the main controller**, and make the SSD.

The new generation of SSDs generally adopts SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, interface, CFast interface, SFF-8639 interface and NVMe AHCI protocol. [1]

What does an SSD look like, you should go to the Internet to check and see our professional information.

In all respects, SSDs (Solid State Drives) are better than HDDs (Hard Disk Drives).

First of all, as a storage device, SSD has a faster transmission speed than HDD, and under the current technology, the capacity of SSD and HDD is basically the same.

When SSDs work, they hardly make sound, but HDDs, we hear sounds a lot.

Sometimes, when we move our laptop, we accidentally put it a little heavier and the computer gets stuck. The SSD is better than the HDD in this regard, that is, the SSD has better shock resistance than the HDD.

Power consumption is also lower.

However, there is a high probability of SSD data error or loss, which is caused by the characteristics of NAND itself, and there is a very low probability that your files will be damaged, and if the damage is serious, it is almost impossible to recover; There are longevity issues, especially SSDs with small capacity and frequent writes.

The benefits of SSDs and the difference between SSDs and HDDs.

1.Quick start, no motor to accelerate the process of rotation.

Under the same configuration of the two computers, a laptop with an SSD took only 18 seconds to turn on the desktop and a laptop with a traditional hard drive took a total of 31 seconds, which is almost half the difference.

3.Relatively fixed reading rotten ridge taking time. Because the addressing time is independent of where the data is stored, disk fragmentation does not affect the read time.

4.DRAM-based SSDs have extremely fast write speeds.

5.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.

6.Low-capacity flash-based SSDs consume less energy and heat in operation, but high-end or high-capacity products consume more energy.

7.There are no mechanical moving parts inside, no mechanical failure will occur, and there is no fear of collision, shock, vibration. This does not affect normal use, even when moving at high speeds or even with flipping and tilting, and minimizes the possibility of data loss in the event of an accidental drop or collision with a hard object.

8.Wider operating temperature range. A typical hard drive can only work in the range of 5 to 55 degrees Celsius.

While most SSDs can operate at -10 to 70 degrees Celsius, some industrial-grade SSDs can also operate in temperatures ranging from -40 to 85 degrees Celsius or even greater.

9.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.

It's an SSD

The so-called SSD is Solid State Drives, which is the solid state drive. Hard drives are generally divided into two types, one is a mechanical hard drive, and the other is a solid state drive. Solid-state drive is a hard disk made of solid-state electronic chip array, generally composed of a control unit and a storage unit (flash chip), the interface specification and definition, function and use method of solid-state drive are the same as that of ordinary hard disk, and the product shape and size are also consistent with ordinary hard disk.

Advantages of SSDs:

1. Fast read and write speed:

SSDs do not use probes to read data, but logic circuits read data, and the continuous read and write speed close to the seek time is very fast, generally the products on sale are more than 500MB s, while mechanical hard disks are generally only 200MB s. The random read and write speed of mechanical hard drives has been criticized, while the random read and write speed of SSDs is very fast, which makes daily operations very smooth. The boot time of the computer using SSD can reach less than 10s.

2. Good shock resistance and drop resistance

As the name suggests, the traditional mechanical hard disk is a mechanized structure, composed of magnetic sheets, rotating motors, mechanical probes, etc., the probe is easy to be misaligned after falling, the motor is also easy to break, and the magnetic sheet is easy to scratch, in short, it is not resistant to falling. SSD, on the other hand, is composed of flash memory particles soldered to the circuit board, without any mechanical parts, and has good shock resistance.

3. Low power consumption:

A mechanical structure is a logic circuit, and the machine requires higher energy.

4. Zero noise:

When working on a mechanical hard disk, the motor will drive the magnetic sheet to rotate, and the probe will touch the disk, which will make noise. SDD pure logic circuitry, no noise.
