4 Reasons and Solutions for Slow SSD(solid state drive)

As a hard disk using NAND as storage medium, SSD is ten times faster than traditional disc mechanical hard disk theory. Upgrading from mechanical hard disk(ssd) to solid state hard disk can greatly improve the speed of computer on/off, the speed of software loading and the fluency. However, some netizens often say that after upgrading the solid state hard disk, their computer does not feel faster or slower. What's wrong? Next, let's get your computer in control!

The importance of properly installing SSD interfaces is ignored


If you are using a laptop, make sure that the extension interface of the motherboard provides SATA 2, SATA 3, or M.2 interfaces, which directly affects whether the SDD you add will run at normal read/write speed. Generally, the reading and writing speed of SSD of SATA3 interface can reach about 500 MB/s, and can only reach up to 300 MB/s on SATA2. The theoretical speed is nearly twice as fast, so it is necessary to pay attention to the correct corresponding interface when adding SSD to the computer.
Some users like to take their notebook's CD-ROM drive apart and transfer it to a hard disk, but many notebooks have only SATA 2 as the CD-ROM interface, which can make it less effective to install a solid-state hard disk. Due to the speed limit of the interface, high-speed SSD speed cannot be used. Half of these users are advised to change the installation location of the CD-ROM drive to the secondary drive (mechanical hard disk) and the hard disk to the SSD when installing SSD.
In addition, many new notebooks are now equipped with M.2 interface. When installing M.2 interface SSD, users also need to see if the interface supports PCI-E channel. The relevant NVMe drivers need to be installed correctly to avoid unstable data reading and machine jamming.
What interfaces and protocols are supported by the motherboard can generally be consulted in the product description. PC Xiao Bai suggests choosing the latest Core 8th Generation notebook or using Z300 Series Chip notebook, which upgrades the SATA 3 interface completely and supports the NVMe M.2 interface SSD. It is very convenient to install the driver automatically under Win10 operating system.

Common data is not installed on SSD disks


solid state drive don't end up on your computer, and the speed at which data is read still depends on where you save the source address. When multiple hard drives are mixed and matched, for example, SSD + HDD is often chosen. If the data is still stored in HDD, it is still futile.
Solution: Reload the system and migrate the data using the newly installed SSD

The capacity of solid state hard disk is too small


To improve lifetime, SSDs(ssd) are usually erased only after the data has been fully written to its maximum capacity once, but when this process occurs, the performance of SSDs can be severely affected. Therefore, if the capacity is insufficient and often needs to be erased, the effect will be discounted.
Solution: Select large capacity SSD.

Solid state hard disks are not optimized, such as no 4K alignment


Solid state hard disk 4K alignment is very important. The so-called 4K alignment actually refers to 4K advanced formatting, which requires 4K alignment of hard disk sectors. The 4K Advanced Formatting Standard specifies that the hard disk sector size is migrated from the current 512 bytes to 4096 bytes (or 4K). This change will improve formatting efficiency, which will help the hard disk to provide higher capacity while providing improved error correction.
When partitioning, it is important to check the 4K alignment. If you find that your SSD does not have 4K alignment, you can search for and download the software Paragon Alignment Tool above to make a lossless 4K alignment for your SSD.
These are the reasons and solutions for whether your computer is slow with a solid state hard disk, especially the 4K alignment problem. After checking these problems, users are confident that the speed will be greatly improved so that your computer can fly smoothly.

Solid-state drives (ssd drive ssd disks)origin

Solid State Drives (Solid-state drives) ssd, referred to as fixed disks, solid state drives (ssd drive) with solid-state electronic memory chip array and made of hard disks, Solid-state drives consisting of control units and storage units (FLASH chips, DRAM chips). SSDs are exactly the same as traditional hard disks in terms of interface specifications and definitions, functions and usage methods, and are completely consistent with traditional hard disks in terms of product form factor and size, but I/O performance is greatly improved compared to traditional hard disks. Widely used in military, vehicle, industrial control, video surveillance, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and other fields.The operating temperature range of its chip is very wide, commercial products (0 ~ 70 °C) industrial products (-40 ~ 85 °C). Although the cost is higher, it is also gradually spreading to the DIY market. Because SSD technology is different from traditional HDD technology, many emerging memory manufacturers have emerged.

Manufacturers only need to purchase NAND memory, and with the appropriate control chip, they can manufacture SSDs. The new generation of SSDs generally useSATA-3 interface, M.2 interface, MSATA interface, PCI-E interface, SAS interface, CFast interface and SFF-8639 interface.

However, when the Solid-state drives is powered off for a long time and placed in a high temperature environment, it will face the risk of data loss. So using an SSD to back up your data is not a great option.

With the rapid development of the Internet, people's demand for data information storage is also constantly improving, and now many storage manufacturers have launched their own portable solid-state drives, and more mobile solid-state drives that support Type-C interface and support fingerprint recognition are launched.

Classification of SSDs


Classification method:


There are two kinds of storage media for solid state disk, one is flash memory (flash chip) as storage media, and the other is dram as storage media. The latest is Intel's xpoint granular technology.
Flash based SSD:
Flash based solid state disk (ideflash disk, serial ATA flash disk): flash chip is used as storage medium, which is also commonly referred to as SSD. Its appearance can be made into a variety of shapes, such as notebook hard disk, micro hard disk, memory card, U disk and so on. The biggest advantage of this SSD is that it can be moved, and the data protection is not controlled by the power supply. It can adapt to various environments and is suitable for individual users. Long life, depending on different flash media. SLC flash memory generally reaches tens of thousands of times of PE, MLC can reach more than 3000 times, TLC can also reach about 1000 times, and the latest QLC can also ensure the service life of 300 times. The annual writing capacity of ordinary users does not exceed 50 times the total size of the hard disk. Even the cheapest QLC flash memory can provide a writing life of 6 years. High reliability, high-quality household solid-state disk can easily reach one tenth of the failure rate of ordinary household mechanical hard disk.

Based on DRAM class:
DRAM based solid state disk: DRAM is used as the storage medium, which has a narrow application range. It imitates the design of traditional hard disk, can be set and managed by file system tools of most operating systems, and provides industry standard PCI and FC interfaces for connecting hosts or servers. The application mode can be divided into SSD hard disk and SSD hard disk array. It is a kind of high-performance memory, which can be written indefinitely in theory. The drawback is that it needs an independent power supply to protect data security. DRAM solid state drives are relatively non mainstream devices. [1]
Based on 3D xpoint class
Solid state disk based on 3D xpoint: it is similar to DRAM in principle, but it belongs to nonvolatile storage. The read delay is extremely low, which can easily reach 1% of the existing solid-state disk, and has nearly unlimited storage life. The disadvantage is that the density is relatively low compared with NAND, and the cost is very high. It is mostly used for fever level desktop computers and data centers.
