7 Useful SSD Facts You Should Know
The use of modern flash memory technology makes solid state drives less resilient, more efficient and more energy efficient than hard drives. Due to the lack of a plate, they are also more shock resistant, making them ideal for laptops and portable storage devices. They are distinguished by their quiet operation even under heavy load. The use of SSD drives in a computer significantly improves its culture and speed. The biggest differences can be seen when booting the system, copying files, and running PC games. The high performance of SSDs allows you to speed up your work several times without worrying about slowing down your computer. But you’d be surprised how many facts you don’t know about SSDs.

Solid state drives have different types of microcircuits
- It is the basic type of drives with the following parameters – SLC (1 bit per cell) – up to 100,000 rewriting cycles. The presented technology provides data storage density per memory cell. This is the most nimble type of memorable equipment, they also distinguished themselves by an impressive service life and are less prone to errors.
- MLC or a multilevel drive with parameters (2 bits per cell) – 3000–35000 rewriting cycles. Their data pairing speed is much slower, since it takes a long time to launch. This is a worthy representative of the family with a sufficient level of reliability that can satisfy the high demands of consumers.
- TLC able to write 3 bits per cell and has from 300 to 3000 rewrite cycles. This technology has higher capacity, high speed and reliability. It combines high rates of information processing speed, loading time and response to system or user commands.
- QLC implies the use of 4 bits per cell – 150-1000 rewriting cycles. It packs a large amount of data, but an increase in the overall percentage of information is reflected on disk, slowing down performance.
SSD has a wider operating temperature range
SSD drives are very commonly used in industry. This is largely due to the fact that they are highly resistant to temperature changes that magnetic disks cannot withstand. After special preparation, SSD media can be adapted to continuous operation in an operating temperature range of -40 ° C to + 85 ° C. Industrial drive bins are often located off-site, which is why this advantage of SSD drives is so important to industry.
SSD is on average 5 times lighter than HDD
The surprisingly low weight is the main advantage of the device. The SSD is 73 grams and the HDD is 365 grams. The new hard drives are most commonly used in netbooks and tablets, making them lighter and more compact.
Solid State Drive Has Three Times Less Power Consumption
Another important parameter is consumption. For SSDs, it is 2-5 watts, while HDDs are 6-15 watts. This makes it possible to carry out a huge number of operations offline without worrying about power consumption. If the user wants to speed up the operation of the device, extend the life of a single battery charge, and reduce the noise level, then it is best to choose a drive of the first type.
SSD 7 times less likely to fail during operation
The presence of mechanical parts in a hard drive increases the risk of failure. This is largely due to high speeds, plate and head rotation. The SSD has a failure rate of 0.5%, while the HDD, in turn, has reached the 2-5% mark. SSDs are very sensitive to unexpected power outages or short circuits. Therefore, it is not recommended to use a laptop without a rechargeable battery. The service life of the disc is 6 years. But in practice, it all depends on the operating conditions, the amount of data storage.
The noise level from an SSD is ten times less than from an HDD
For many users, this criterion can be decisive when buying. In HDD, the noise level reaches 35-50 dB (A), which is very high, while the SSD is ten times quieter, especially if the work is carried out in a closed, stuffy room. Quietness enables SSDs to take a leading position in the market, especially in office and home PCs.
Defragmenting greatly accelerates SSD wear
This process moves portions of files onto the physical surface of the disks, allowing the hard disk to load all of the data more efficiently and faster. However, in the case of SSDs, there are more problems than benefits. The defragmentation process quickly wears out an SSD while performing a huge number of operations, which is the most important factor in the lifespan of an SSD.
