Classification and selection of solid state drives

Compared to mechanical hard disks, solid-state hard disks are much faster in reading files and booting. It is recommended to buy SSDs for system disks. The NAND flash memory chip is a crucial component for storing data in SSDs. Different types of flash memory particles have varying lifespans and costs. For more information, please refer to the detailed explanation of the latest SSD solid-state hard disk particles QLC, SLC, MLC, TLC. Many netizens may wonder how to choose a solid-state drive and what the difference is between the widely used SATA and M.2 solid-state drives. Therefore, the following will provide a detailed introduction to the differences between SATA solid-state drives and M.2 solid-state drives, helping you make an informed decision when purchasing a solid-state drive.

SATA SSD, utilizing the SATA channel and AHCI protocol. The mainstream SATA 3.0 channel currently offers a maximum transmission speed of 6Gbps, with actual read speeds reaching up to 560MB/s. Despite the growing popularity of M.2 solid-state drives, SATA remains the dominant interface standard in the market. Opting for a SATA SSD ensures compatibility with both old and new computers, eliminating any compatibility concerns.

2. M.2 SSD

M.2 SSD is a specification for internally mounted computer expansion cards and connectors, especially for small ultrabooks and tablets. M.2 SSDs are smaller in size and have faster interface transmission speeds compared to SATA SSDs. They are divided into SATA and PCI-E, with corresponding protocols AHCI and NVMe. NVMe SSDs provide better performance with faster transmission speed and low latency. Look for the NVM Express logo on the outer box or product label to identify NVMe-compatible SSDs.
If the packaging is discarded, you can use AS SSD Benchmark to determine if the hard drive is NVMe or AHCI protocol. A comparison of two M.2 interface SSDs without protocols is shown in the picture:

m2 interface protocol comparison

The test results reveal a significant difference in AS SSD running points between the two. The NVMe protocol solid-state hard disk on the left has continuous reading and writing speeds of 1297MB/s and 976MB/s respectively, while the AHCI protocol solid-state hard disks on the right have speeds of 518MB/s and 502MB/s respectively. The NVMe protocol exhibits superior transmission performance compared to the AHCI protocol. For M.2 solid-state drives with SATA channel, the theoretical transmission speed does not exceed 600MB/s, whereas an NVMe protocol supported M.2 solid-state drive can theoretically achieve over 2000MB/s reading speed. Therefore, the fastest way to determine if it supports AHCI or NVMe protocol is by distinguishing the reading speed.

1. Preparations for installing a solid-state drive (SSD)

Preparation tool for installing SATA SSD : Phillips screwdriver, SATA dedicated data cable, anti-static gloves (use in winter), 2.5-inch to 3.5-inch hard disk bracket (optional). Preparation tool for installing M.2 SSD : Phillips screwdriver, M.2 hard drive screws.
Phillips screwdriver: Screwdriver It is recommended to use a screwdriver with a magnetic black head, so that the screw is not easy to fall off during operation.

Most solid-state drives do not come with SATA3.0 cables, so they should be purchased separately. It is advisable to buy a moderately priced cable with one end having an elbow and the other end being straight. Confirm if the connecting cable has words like SATA3 or 6Gbps, as this indicates support for the SATA3.0 standard. When connecting, it is recommended to attach the straight end to the motherboard and the elbow end to the solid-state drive for easier and neater internal wiring of the host.

Anti-static gloves (necessary for winter operation) Since the human body is very prone to static electricity in winter, if it is operated with static electricity, it will be very easy to break down the capacitor inside the motherboard. In summer, it can be operated without gloves.
SSD Installation
2.5″ to 3.5″ HDD bracket (optional) Some older chassis may not have a 2.5-inch hard disk installation space reserved during design. At this time, use a 2.5 to 3.5-inch hard disk bracket to meet your SSD upgrade needs. Similar hard disk brackets on the market are generally compatible with SATA and IDE interface, and is suitable for all kinds of chassis, whether it is a standard type or a screw-free installation chassis.

2. How to install the solid state drive on the PC host

Very important: please disconnect the power on the host PC before operation
There may be two interfaces on the motherboard of a PC computer, namely SATA and M.2 interfaces, so if you buy a SATA SSD, then connect the SSD to the SATA interface, and the M.2 interface is the same.

① How to install SATA 3 SSD It should be noted that SATA3 refers to the version of SATA3.0, and the interface speed can reach up to 600MB per second, which is twice the maximum of 300MB per second of SATA2.0 version. In the following, I will teach you the correct installation method, lest you buy a SSD with SATA3.0 interface but still use SATA2.0 by mistake. When installing, the most important point is to connect the SATA3.0 data cable to the SATA3.0 interface of the motherboard to obtain the highest transmission speed. You can confirm which interface is SATA3.0 by checking the motherboard manual. If the motherboard manual is not with you, you can also judge according to the text on the motherboard, such as:

ssd installation
If there is SATA 6Gb/s or SATA6G next to a certain SATA interface, then you can be sure it is this interface.
ssd installation
If there is no font, it can only be judged from the color. Generally speaking, it is the one with the most special color, for example:

② How to install M.2 SSD First of all, you need to check whether the motherboard supports the M.2 interface. Generally speaking, M.2 SSDs come in five lengths: 2230, 2242, 2260, 2280, 22110, but not every motherboard or notebook can accommodate them. The above numbers can be decoded as width lengths, eg 2242, meaning 22mm wide and 42mm long. The most common sizes are 2242 and 2280 (42mm and 80mm long). If it is confirmed that the M.2 interface is supported on the motherboard, we find the M.2 interface on the motherboard, which is generally marked on the motherboard, as shown in the following figure: m2video

After the solid-state drive SSD and its supporting system are successfully installed, you can still More in-depth optimization , for you who are pursuing performance, the following chapters must be read.

SSD hard disk optimization

TipsThis chapter is mainly optimized based on SSD with SATA3.0 interface. Other versions of SATA or SSDs with other interfaces have different locks on data, so this cannot be used as a reference.
Although SSD performance is excellent, unlike traditional mechanical hard disks, SSDs must be properly optimized and configured to truly achieve high-speed reading and writing. Otherwise, high-speed SSDs can only be used at low speeds, wasting the original performance of the hardware.

Pre-steps: Confirm that the SSD has been inserted into the SATA3.0 interface on the motherboard

This step is very important, if the SSD is not connected to the SATA3.0 interface, then all subsequent optimizations will be meaningless. Of course, if your motherboard does not support SATA3.0, you can skip this step directly. It’s very simple, as long as the software is used for a simple test, it can be known that running the software AS SSD Benchmark on the host, in the test results, as long as the data in the Seq row is above 300MB/s, there is no problem.
ssd installation

1. Confirm that the BIOS and Windows have been set to support AHCI

What is AHCI?
AHCI (Serial ATA Advanced Host Controller Interface) is an interface standard developed by multiple companies, including Intel, AMD, Dell, Marvell, Maxtor, Microsoft, Red Hat, Seagate, and StorageGear. It enables storage drivers to utilize advanced serial ATA functions such as local command queuing and hot plugging. By supporting and utilizing AHCI, the motherboard can unlock the potential acceleration function of SATA hard disks, resulting in a roughly 30% increase in read and write speeds.
Notice : If your hard drive is not an SSD but a traditional mechanical hard drive, please do not use AHCI , if you use it forcibly, it may cause the Windows system to freeze, resulting in a sharp drop in performance.
Setup steps:
1. To setAHCI, you need to enter the motherboard’sBIOSsystem.
Different motherboards have different access methods, and you must choose the correct access method.
2. After entering the BIOS, you need to find the option of SATA mode and set it to AHCI. For detailed setting methods, please refer to your BIOS manual
ssd installation
3. If you used an IDE disk to install the Windows system before and want to migrate the system directly to a new solid-state drive (SSD), then you also need to modify the registry information to enable the Windows system to use AHCI. The specific method is as follows:
a. Press Win + R
Win+R key
b. Type regedit
run regedit exe and open registry editor
c. Open HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ iaStorV, double-click the Start that appears on the right, and modify the value inside to 0
ssd installation
d. Open HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ storahci, double-click to modify the Start item inside, and set it to 0.
After the modification is complete, please restart the system. After restarting, Windows will automatically configure the driver of the SSD to support AHCI mode according to these parameters.
ssd installation

After completing the above 4 steps, we start AS SSD Benchmark again. In the position shown in the figure, as long as you see the logo of storahci or iaStorA, it means that your system has fully supported AHCI.

2.4K alignment optimization

If you do not use professional migration software or install the system yourself, it may cause the SSD to not be 4K aligned, resulting in performance loss. If you don’t understand what is 4K alignment? You can check out this article,4K Alignment for SSD Come find out.
First of all, we still run AS SS Benchmark to see if the current SSD has 4K alignment, as shown in the figure: 1. If the icon appearsXXXXX K – OK, indicating that the SSD has been 4K aligned, then you can skip this chapter and go directly to the next chapter. 2. If theXXXXX K – Failed, it means that the SSD has not been 4K aligned. Don’t worry though, here’s a freeware that does lossless system 4K alignment.

Important note: Please back up important data on the system disk before running.
  1. 1. Download the free software :
  2. Unzip to a local folder, double-click PastAssist.exe in the folder
  3. After entering the software, select your system disk, as shown in the figure:
ssd installation
4. Click “Partition” -> “Advanced Operation” -> Partition Alignment
ssd installation
5. Click “determined” in the pop-up window.
Then depending on the size of the partition, you may have to wait for a while. Once complete, run AS SSD Benchmark again to confirm.
ssd installation

3. Don’t fill up your SSD

Reserve a certain amount of free space for the SSD (it is recommended to reserve about 10% of the capacity), which is more conducive to its performance. Because the solid state drive under full load will be more prone to the possibility of crash. (Depending on the difference of the main control chip, some SSDs will not drop when fully loaded, while some SSDs will drop seriously when fully loaded.)

4. (Optional) Use the RST driver provided by Intel to improve HDD performance

NOTE: The technique apply only Because the system is installed on the traditional mechanical hard disk, because of other reasons, they are unwilling to migrate the Windows system to the SSD (for example: relatively speaking, the mechanical hard disk will be more stable, and the data volume of the system disk is too large to be migrated to the newly purchased SSD), and the SSD is used as The use of additional storage disks. If you have already used SSD as the system disk, please skip this chapter.
What is Intel RST?

Intel RST: Enhanced Performance and Reliability Intel Rapid Storage Technology (IntelRST), formerly known as Matrix RAID, is a Windows-based application that boosts performance and reliability for desktop, mobile PC, and server platform systems with SATA disks. By utilizing one or multiple disks, users can experience improved performance, reduced power consumption, and enhanced data protection against disk failure.

why install Intel RST ?

Mainly two factors
1. The SATA old AHCI driver that comes with Windows has never been updated since 2006, even the latest version of Windows 10. The ACHI driver provided by Intel’s RST technology is updated almost every year. Therefore, using this driver will have a certain degree of performance improvement.
2. Intel RST Rapid Storage Technology refers to using SSD as a disk cache to speed up system loading and running. In some cases, if the SSD cannot be used as the system disk, this technology can greatly improve the system speed.

The conditions for realizing Intel Rapid Storage Technology (Intel Rapid Storage Technology):

1. Intel chipset motherboards that support this function 2. Intel Core series processors. Such as: Intel Core i3, i5, i7 processors. 3. A traditional mechanical hard drive HDD and a solid state drive SDD According to Intel’s official regulations, the capacity of a solid-state drive cannot be lower than 18.6GB and not higher than 64GB. 4. At least one mechanical hard disk is used as the system disk. 5. The hard disk mode of the motherboard BIOS is set to RAID mode. 6. The capacity of all disks managed by RST cannot exceed 2.2TB (all solid-state drives + traditional mechanical hard drives)
