What to look for when buying an SSD for a desktop computer

1 SSD 4k aligned.

You can use the Win7 system disk to partition and format the SSD, or use the hard disk partitioning tool DiskGen software (at least the version or above) to align the SSD in 4K.

2. Enable the AHCI function on the hard disk.

At present, most desktop computers are in IDE mode by default, and to enable the HDD AHCI mode, you need to enter the BIOS to set it on. Most notebooks have adopted AHCI mode by default.

The general steps to enter the BIOS to turn on the hard disk AHCI mode are: restart the computer, press the DEL key to enter the BIOS when starting the computer, select Devices ATA Drives Setup Configure SATA as AHCI, and finally press the F10 key to save and exit the BIOS

In addition to the above two basic and important knowledge points, there are some other aspects that have a greater impact on the performance of the SSD, such as the motherboard turning on the energy-saving function and the misconnection of the third-party SATA3 interface, etc., which will have a greater impact on the speed of the SSD, which are introduced below.

1) The performance of the SSD is degraded due to the energy-saving mode enabled on the motherboard.

Usually, the motherboard's energy-saving function is enabled, and the CPU frequency will be reduced, which will also lead to a decrease in the performance of the SSD, because the CPU frequency will be reduced by 10% when saving energy, and it will be 10% slower when sending instructions, so the theoretical SSD performance will be reduced by 10% during the test, so if you want to give full play to the best performance of the SSD, please do not turn on the energy-saving mode on the motherboard.

2) Misconnection to the third-party SATA3 interface affects performance.

Nowadays, many mainstream motherboards support interfaces, such as Intel's B75 motherboards and AMD's A75 motherboards have interfaces, which are also very important for SSDs, if the motherboards we choose do not support interfaces (such as H61 or A55 motherboards do not contain interfaces), then the performance of SSDs will be greatly affected. On the other hand, the test results of the third-party SATA3 interface solution are almost completely inferior to the results of the native SATA3, especially in the starting applications speed is 20MB S. （starting applications：

Open the PCMark 7 Specification Document with IE and wait for a fully responsive hard disk operation record. 85% of them are random reads. As a result, the score dropped dramatically, and the use of a third-party SATA3 chip solution greatly slowed down the random speed, resulting in a sharp drop in performance.

The main attention is 4K alignment, AHCI, SATA3 interface!

Desktop SSD Installation Tutorial.

1. Flash memory particles. There are three main kinds of flash memory particles on the current solid state drive: SLC, MLC, TLC, SLC stores 1 bit per unit, MLC stores 2 bits per unit, and TLC stores 3 bits per unit, for solid state drives, the more storage bits of a unit, the larger the capacity of the modified unit, and the lower the cost, but the more storage, it is more difficult to identify, and the stability and performance will also be reduced, so the three particles on the hard disk are SLC>MLC>TLC in performance.

2. Main control chip. The main control chip of the solid state drive is the processor of the solid state drive, and the algorithm used by the chip plays a decisive role in how to read and write data, how to correct data errors, how to deal with bad blocks, etc., and the quality of the main control chip and the algorithm play a certain role in the life of the solid state drive.

3. Interface. The interface of the SSD is closely connected to the motherboard, after you buy an SSD, your motherboard does not have the corresponding interface, your SSD will not be usable, there are currently 3 common SSDs:

1) SATA interface. Now some computers have the popularization of SATA interface, which is also the most commonly used interface of SSD, and the SATA interface has been developed to SATA III, and the interface speed can reach 6G S.

2) mSATA interface. This connector is a miniature version of the SATA connector, and its speed and performance are actually similar to the SATA connector, but the size is relatively small, and it is usually used in those ultra-thin laptops.

3. Interface. This interface is the latest generation of SSD interface, whether it is in appearance or speed is not the first 2 more excellent, the interface is divided into SATA (this SATA refers to the SATA channel) and PCI-E two types, of which the PCI-E interface type of SSD is the fastest, excellent performance, users in the purchase of SSD, do not buy an interface casually. To purchase an SSD with an interface on the corresponding motherboard.

Is there anything to look out for in Kingston's hard drive 400 to 600 price range?

When evaluating the best hard drive, performance, stability, capacity, and ** are all important, as well as drive capacity per drive, cache capacity, and drive warranty. Very similar criteria are used when buying a new hard drive: first capacity, then **, then other related features, including data transfer rate, spin speed and cache size, linear and random IOPS performance is becoming more and more important.

But there's another smart factor to consider when buying the best hard drive: the intended use.

Good afternoon, dear, I'm honored to answer your <>

When buying a laptop SSD, pay attention to the following: pay attention to the interface and protocol of the notebook, pay attention to the purchase of a suitable SSD, the interface protocol should be compatible, choose a good temperature control, choose the capacity of the SSD, and prepare the tools needed to replace the SSD. Check the supported interfaces and protocols first, and be sure to visit the town at the same time.

The heat dissipation conditions of the laptop are relatively poor, and the temperature of the SSD is too high, which will reduce the performance. When replacing an SSD, the most fundamental consideration for buying a SATA SSD or NVMe SSD is what type of interface the user's laptop motherboard supports. An SSD, or SSD for short, is a computer storage device that primarily uses flash memory as permanent memory.

1. Hard disk capacity: Generally speaking, the capacity of solid state drives is generally small, with a capacity of 128g-512g, while the capacity of traditional hard disks can reach 1t. Therefore, when choosing a laptop SSD, you should first consider your actual needs and choose the right capacity.

2. Hard disk interface: There are generally three interfaces of solid state drives: SATA, PCIE, and different interfaces have different hard disk performance. Therefore, when buying an SSD, you should first determine whether your laptop supports this interface to avoid unnecessary waste.

3. Hard disk speed: The read and write speed of the solid state drive is very fast, generally more than 500mb s, while the read and write speed of the traditional mechanical hard disk is generally about 100mb s. 4. Hard disk**:

SSDs** are relatively expensive and come in different brands, and generally speaking, better quality brands** are also higher. Therefore, when choosing a laptop SSD, you should choose the right one according to your actual situation. 5. Hard disk brand:

The brand quality of SSDs is also different, generally speaking, the price of better quality brands is also higher, so when buying laptop SSDs, you should choose a better quality brand to ensure the reliability of the hard drive. The above is about the purchase of laptop SSD to pay attention to, before buying should consider the capacity of the hard disk, interface, read and write speed, ** and brand,

Step 1:Let the collapse determine the interface and protocol supported by the notebook,This can be checked on the official website or directly sliding to call to the customer service of the purchase store to inquire about the second step:Buy the interface Protocol-compatible solid-state,It's also very simple to destroy the wild。

Not the rest.

Need to consider length, width and height when buying an SSD?

No, you don't. The key two steps are the first step:Determine the interfaces and protocols supported by the notebook,This can be checked on the official website or directly ask the customer service of the purchase store Step 2:Buy this stupid mouth The association finger picks up the compatible solid,It's also quite simple。

If you buy it by mistake, you can't use it.
