Generally speaking, SSDs and HDDs consume similar amounts of power when they are working under the same high loads, or when they are also in a dormant state. However, SSDs still have some advantages in terms of power performance, such as the fact that SSDs do not have an internal rotating motor, and therefore consume significantly less power in the idle state. Second, because there is no ramp-up or ramp-down startup time, SSDs enter or wake from hibernation in less time and more frequently. Finally, SSDs are able to do the same work in less time and therefore enter hibernation earlier. All of these advantages make SSDs more energy efficient than traditional hard disks in the real world.

First of all, memory and hard disc are different in function. Hard discs are mainly used for long-term data storage to retain as much user data as possible, while the main function of RAM is for temporary data storage and data exchange between the CPU and the operating system, so that the user can use the programme as smoothly and quickly as possible.

Secondly, they are also different in performance. The performance of the hard disc mainly depends on its data transfer speed and storage medium, only need hard disc data reading speed is fast enough; while the performance of the memory is dependent on its processing data speed, that is, what we call the frequency, the faster the frequency of memory, the faster the speed of data exchange, therefore affecting its performance.

Finally, the size of their capacity also varies greatly. Hard drive usually has a larger storage capacity, common SSD and HDD hard drive capacity of hundreds of GB to several TB; while the capacity of the memory stick is relatively small, common only 4GB, 8GB, 16GB, etc., although with the development of technology, also gave birth to a single 48GB memory stick, but compared with the hard drive is still a huge gap.

The performance of any SSD is determined by a combination of raw flash bandwidth, the efficiency of the loss balancing algorithm (firmware), and the interface (SATA, PCI-E, etc.). With SATA interface speeds stuck there, there’s no point in having great flash performance.

Buy two memory sticks with exactly the same parameters, that is, if you want the memory capacity is 8G, then buy two 4G, if you want 16G, then buy two 8G, now many manufacturers are directly producing sets of strips, the budget allows direct purchase of sets of strips can be. Then insert them at intervals or in the same colour on the motherboard.

The answer to this question is a bit more complicated. The way SSDs store data is significantly different from traditional hard discs, for example, to prevent frequent reads of a storage unit that can lead to rapid aging, SSDs tend to use a ‘wear levelling’ mechanism that averages out the number of reads and writes to each block. Current operating systems are not prepared for this.

The main principle of the disk defragmenter is to put the data that needs to be read frequently where it can be accessed at high speed, and the data that is rarely accessed is piled up in the corners. The principle of SSD is that it can find any piece of data very quickly. Current disk defragmentation tools just can’t do anything to optimise the file system of an SSD. Therefore, my recommendation is that SSD users should disable automatic disk defragmentation and not do it manually either.

Timing refers to the latency of the memory, and is generally shown using four sets of parameters with dashes, e.g., 16-18-18-36, CL-TRCD-TRP-TRAS, respectively;

We generally focus only on the first parameter, the CL value, which can be roughly interpreted as the reflection time; in most cases, the lower the CL value, the better, given the same memory frequency.

Like two sides of anything else, SSDs and HDDs have their advantages and disadvantages. By far the biggest disadvantage of SSDs is cost and capacity, while the biggest advantage is performance. Additionally, SSDs require less power to perform the same operation, which means that laptops can have longer battery life and data centers can save significantly on their electricity bills. Because they are more resistant to shock and vibration, SSDs are also better suited to mobile devices than HDDs. SSDs can even be cheaper than traditional hard drives if capacity is not required.

    (1) Determine the type of memory stick based on the CPU and motherboard;

　 (2) Determine the capacity of the memory;

　 (3) Determine the quantity: according to the number of slots and the number of channels supported by the motherboard;

　 (4) Determine the frequency of the memory stick according to the frequency range supported by the CPU and motherboard: memory sticks with low timings perform well, and memory sticks with higher frequencies perform better at the same timings;

　 (5) Determine the brand: Pay attention to the memory particles and timings.

This is a complex issue. Over the life cycle of an SSD, many factors can affect its performance. Not the least of these is the issue of data fragmentation. Unfortunately, there is no way to externally measure the impact of data fragmentation on an SSD. As stated above, test programs may be able to detect a performance difference between an SSD’s internal storage stripe or not, but it doesn’t significantly affect the user experience. Optimization of the SSD file system will further address this issue in the future.

Computer to upgrade memory, the first step is to determine what kind of memory stick is installed in the computer.

The first method is to read the memory stick information in the boot information, some computers do not show the basic information on boot or need to press ESC or Tab key to see it, or read it in the BIOS.

The second method is to use system tools or commands, or third-party software such as CPU-Z, Thaiphoon, LU Master, etc. to read, the disadvantage is that it needs to be installed.

The main reason is that “reasonable capacity” flash memory does not take up much space in terms of physical specifications, and it is more appropriate to make it 2.5″ or 1.8″. The term “reasonable capacity” refers to the ability to provide enough storage space for real-world applications at a reasonable price. If the flash memory to fill a 3.5-inch hard disk space, the price must be quite amazing.

Many people may have a misconception about this, thinking that SSDs don’t come in 3.5″ models because it’s only for the laptop market. In fact, SSDs have never excluded desktop PCs, and there is no difficulty in installing a 2.5-inch SSD in a 3.5-inch drive bay in a desktop PC. Moreover, there is no difference between the SATA interfaces of 3.5″ and 2.5″ hard disks.

SSD is able to replace the traditional mechanical hard drive to become the newest system disk which is the biggest credit to the NAND latency-free response speed, and this data in the SSD specifications using IOPS (random read and write) to indicate that the greater the value of IOPS indicates that the SSD in the system application of the “sensitivity” is also higher.

The reason for this phenomenon, the first may be caused by the motherboard chipset itself, some of the old motherboards only support 256MB memory capacity (i815 series only support 512MB), beyond the part, can not be recognised and used. Of course, there are also some cases is due to the motherboard can not support high memory particles caused by.

The solution is to replace the motherboard or memory. Also in some cases the problem can be solved by adjusting the insertion order of the memory.

Sometimes, after installing new memory sticks, the computer does not recognize them. This may be due to the fact that the memory sticks are not properly inserted into the slots or there is dirt on the slots. In this case, we should check if the memory sticks are inserted correctly and gently wipe the slot gold fingers with an eraser to ensure good contact with the slots.

No, it is not necessary or recommended to defrag an SSD. Since there are no physical disks, there is not need to organize the data in order to reduce seek time. Oreton SSDs have TRIM, which serves the same basic function to make your drive faster without subjecting the drive to the extra workload. Defragging an SSD will put undue wear and tear on the drive and may actually shorten its life.

The capacity is shown in “Megabyte” (same with Hard Disk Drive, 1MB = 1000KB). In Windows environment or DOS mode, 1MB equals to 1024 KB.  Therefore 1GB is approximate 953MB.

The actual available memory on the device is less than what is listed on the package. This is due to small discrepancies in file format and algorithms used by various operating systems. In addition, a portion of memory space is reserved for system files and data sectors for better performance.

NVMe stands for Non-Volatile Memory Express. Non-Volatile Memory means that it does not require power to retain information.NVMe takes advantage of pipeline-rich, random-access, memory-based storage. It provides significantly higher data transfer rates than traditional disk interfaces such as SAS and SATA.

The NVMe protocol can be used with most standard interfaces which includes M.2 / PCIe / and SATA express.

No, they are different; M.2 supports both SATA and PCIe storage interface options, while mSATA is SATA only. Physically, they look different and cannot be plugged into the same system connectors.

Self monitoring, analysis, and reporting technology (S.M.A.R.T.) is a built-in monitoring feature for regular hard drives and solid-state drives. It allows users to monitor the health status of their devices. This operation is achieved through monitoring software designed specifically for the S.M.A.R.T. function. All Oreton solid-state drives support S.M.A.R.T.

Paired memory may not necessarily need to be installed, but some higher-order motherboards have motherboards that support dual or four channels, which can (in some cases) significantly improve performance.

Reminder: If using two or four memories, their memory capacity must be the same, and it is recommended to use the same brand of memory to avoid a state of inability to power on.

No, the speed, voltage, and memory slot (or gold finger gap) of DDR3 and DDR2 are different.

Depending on your needs, increasing memory capacity can allow you to run multiple applications at the same time, but there may still be some differences in their operating speed. Suggestions are as follows

• Mostly used for browsing web pages and office documents, homework programs: 4GB or 8GB
• Mainly used for simple games and video playback: 8GB or 16GB
• Mainly used for drawing software or heavy game players: over 16GB

ECC (Error correcting code): When a storage device with this function encounters an error while accessing data, the device will automatically detect and fix the error to maintain normal system operation. This technology can increase the accuracy and security of data.

CAS latency, also known as CL value, refers to the amount of time a computer needs to wait before actually starting to read data from memory. The higher the CL value, the longer the delay time required, which usually increases with the increase of frequency. It is not the best choice to pursue a lower CL. For example, CL2 refers to the time required to access data in memory at two frequencies. Generally speaking, the smaller the CL value, the more advanced the process used, and the higher the requirements for the motherboard.

Dual channel is designed by the CPU architecture and operates in parallel. When connecting two memories, the bus width will reach 128 bits, and the difference will be known when calculating the memory width. After opening dual channels, the bandwidth can be doubled and the efficiency will also increase; As for whether it can be increased to twice the speed, according to testing, it seems impossible, but it is very helpful for improving memory performance. Depending on the characteristics of each motherboard, there are slight differences, which can be combined with overclocking to enjoy different performance experiences.

If paired with memory of different frequencies, the system will automatically run dual channel performance with the minimum frequency memory.
