Foreword : Ever since the National Day holiday last fall, I tossed my computer at school. As a hardware enthusiast, I still insisted on selecting a host computer in front of my laptop and a host. The ITX host is a program that I have already set up. In the winter and summer vacations, I can bring home, so the chassis is selected by a new brand of Plymouth at P115EA. Now it has been summer vacation. By the end of August, the school will become a second year old student. Not how toss, also tossing once, tossing extent is also the case, is to improve the cooling, the 3.5 mechanical hard drive replaced by 2.5, plus a Micron MX200 as a software disk, that toss is still aunt Aunt Zhang This is the card below. If you are interested, you can check it out because this toss is the continuation of the last time. So I have summed up my series of articles. In fact, the change of disk was accidental, and my friend asked me if I wanted it or not, so the price of conscience fell, and what was not written in this dish was a new one. I was the first time to use Plextor's solid state, and Pulte's reputation was very good in the players' circles. Many people recommended their family's hard drive, especially the M×S series. Although they hadn’t used it before, they helped friends’ notebooks before. Upgraded over M5S. This M7V is also a new product of Plextor, V Series positioning entry level so-called cost-effective models (P series positioning high-end, S series is the mainstream, V series is an entry), but also Plextor the first test of water TCL , Officially stated that there are 2,000 P/E lifetimes (such as twice as much as the average TLC), all data can be comparable to or even beyond the mainstream MLC, swept the TLC not fly past the past, become a new area of ​​solid-state hard drive milestone. And the M7V new third-generation LDPC intelligent error correction technology. Compared to most of the SSDs in the market using the most basic ECC technology, LDPC can handle more complex coding and have different error correction capabilities. At the same time, LDPC technology can be more suitable for high-speed communication NAND, further enhancing the life and stability of TLC. Configuration: Processor: lntel E3 1231 V3 Memory: Crucial/Micron Smart Edition DDR3 4G DDR3 1600×2 Mainboard: MSI/MSI B85I LGA1150 ITX Graphics Card: MSI/MSI GTX 960 2GD5 OCV1 Power Supply: Silverstone / Yinxin SX600-G 600W SMART information is as follows: CrystalDiskMark test: TxBENCH test: PCMARK7 test: Mark7 score:5091 MARK8 total score 4898, fairly good Download address: link At present, the three major black technologies are not supported by the old M6G-2242/M6G-2260 and M1-M5 products. The current M6 and M7 series can support it. PlexCompressor automation technology actually compresses unused data for more than 30 days, saving disk space. After all, SSD capacity is still relatively expensive. Every time the PlexCompressor is turned on, it is automatically turned on. After each data compression, the compression ratio and the available capacity after compression are displayed. In fact, to say, this is not what black technology, the system itself comes with compression, but PlexCompressor is more intelligent, automatically find out more than 30 days of unused files when the system is free to compress. PlexVault is the most practical one I think of these three black technology softwares. In fact, everyone has a little secret that they do not want others to see in the computer, especially men have a little hobby (you know) do not want to be discovered by others. Little secrets, or any important data files that are afraid of being snarled by others, must not give these things to others. There are only two ways to do this, or put those little secrets or important documents in a folder. Setting up a hidden folder or setting up an encrypted compressed package, but a bit of computer-based infrastructure knows how to view hidden folders, and encryption compression is so cumbersome, so you have a PlexVault you know how easy it is. to sum up: Recalling that TCL was still a child to be discriminated against, he represented low performance short-lived, he did not attract people to see, and from the above point of view the current speed is no longer a criticism of TLC, then TLC and MLC left life expectancy What's the difference? In fact, TLC no matter how optimization can not achieve the kind of performance of MLC, TLC to achieve such a key point is that M7V uses SLC Cache cache technology, this technology can be understood as the solid state itself Plexturbo, is a part of the TLC draw out Capacity simulation SLC work, in fact, manufacturers have done so often, such as the famous Samsung 840Evo, running points directly using the slc cache to run points, and tlc does not run sub-test, so running sub-data looks very pretty, The main reason for running sub-software files is newly established. When a new file is created, the hard disk automatically calls the SLC cache to perform read/write operations. If the size of the tested file does not exceed the capacity of the SLC cache, the read/write performance is the SLC cache running. The capacity of the slc cache that tlc continue the following file, then the speed will be restored tlc speed, so that the prototype is exposed, that is not to say that cheating it? Actually, how do you look at it? There are actually suspicions of certain cheating, but it is also a common phenomenon in the industry. As the price of SSDs continues to decline, TLC’s credit is indeed indispensable. With the popularity of TLC SSDs, SLC is becoming more popular. The application of Cache will also be more common, but if you really want to say that the SLC cache technology runs cheating, then it is a stick killing, at least not better than no, slc cache is also considered an optimization, slc cacha It is also possible to write random writes together and write them into flash memory to reduce a large amount of GC operations. To a certain extent, it can also be regarded as reducing the write amplification. This further reduces the load and also optimizes the life span. It is also particularly beneficial to TLC. Is that m7v worth buying? Tlc itself is a low-cost market, the popularity of solid products, after all, a sub-price goods, and Plextor claims that m7v has 2000 p/e times, for the general tlc is more than doubled, can be regarded as a tlc landmark And, with the consistent stability of Plextor’s firmware, the purchase of Plextor’s products at such a low price is worth considering. Ah ~ cheap, TCL performance is good, long life, firmware assured What is Car Ethernet Vehicle Router,Vehicle 4G Router,Vehicle 4G Wireless Router,Vehicle Wifi Router Shenzhen MovingComm Technology Co., Ltd. , https://www.movingcommtech.com
Tossing this host is also strenuous, tossing for a week back and forth, because in the school but also to school, can only be tossed in the absence of classes and weekends, it may be said that a host actually spend so long time, in fact, I mainly More time is spent on customizing online. As a person who likes tossing and rigorous to the host, he prefers to determine the length of each power cord to pursue a more perfect alignment. 
When customizing your own lines, especially the motherboard 24pin power supply is the most tedious, because the line sequence of each brand power module interface is not a standard, then only to learn to measure the voltage of each interface, find the correct line sequence, This will ensure that the host will not boom. 
In fact, because of the video card problem has also been delayed for several days, at first to force the belief to buy the MSI GTX960 GAMING 4G, the results of this card 14cm width is simply not close to the chassis side board, behind only for the MSI's short card GTX 960 2GD5 OCV1 
In fact, the alignment is also quite satisfactory. In fact, the more enjoyable is the tossing process and the joy of success. 
In fact, to the extent of the second toss is better, also considered some small money, bought a 2.5 mechanical hard disk and a 250G Micron MX200 to improve the whole experience, there are two gentle typhoon typhoon GT1850 and two Sanyo 9s 8025 (both God fan) to improve the host cooling, specific toss or see the article at the beginning of the card. 
Pulling that much is actually a way of introducing my love machine to valued friends. It's also a little show off. After all, it's hard work (also includes code word writing and sharing) If you don't recommend my little show off, give it to I like the reward. Well ~ directly to the subject of this toss it, the original system disk used by the host is still with me a few years of SanDisk X110, just 64G, up to also installed a system, solid state prices a few years ago can be imagined, Or children, can only afford the 64G version of the price, but it is still used by friends. Today, the total number of P/Es on that disk is also more than 300. One capacity is not enough. Two speeds cannot be seen. So prepare a replacement disk, this is the protagonist: Plextor M7VC 128G 
M7V has a total of 128G, 256G, 512G three versions, continuous reading and writing have reached 500MB / s, 128GB in the random write and 256GB and 512GB some gap, so is the SSD, the greater the capacity the better the performance of the long life, After all, it's money. 
Well, my aunt and daddy are very eye-catching. In the last year, Pu Kete launched the M6V victory red edition to commemorate the 70th anniversary of the Anti-Japanese War. The M7V is basically red and green. The specific configuration uses Marvell's 88SS1074 master control with Toshiba's original 15nm TLC flash memory. 128G version is equipped with the current mainstream SLC Cache cache, improve hard disk write (running points) performance, later I will introduce to you what is the next SLC Cache. In addition to these reliable materials, Plextor's firmware is also very stable, and there are three major weapon, PlexVault file encryption technology, Plexcompressor intelligent compression technology, Plexturbo memory acceleration technology, the first time using Plextor SSD will definitely experience These three black technologies, and I will introduce later 
Have experienced various ransack software afflictions and this one-week use and the former use NAND write volume 353GB, fast writes have 3P/E AS SSD Benchmark Test:
Read score of 336 points, write score of 234 points, total score of 753 points, for a TLC product running points really good, continuous reading 525.28MB / s, continued to write 501.58MB / s, random 4K read 32.71MB / s, random 4K like 76.38MB/s 
Anvil's Storage Utilities test:
PC MARK8 test:
Black Tech One Plexturbo Technology:
In fact, Plexturbo is the so-called memory acceleration technology, in fact, this technology is not new, a long time ago already have such software Ramdisk, FacnyCache and other such software, Samsung also has similar RAPID technology, the principle is to obtain a certain amount of memory, as the memory Hard disk to work, so that the speed is doubled growth (the picture shows the open Plexturbo Run points), in addition to acceleration outside the technology also supports hot data prefetch, that is, each time the boot is often read hot data into memory, in addition to speed up The speed can also reduce the write wear of the hard disk to extend the life to a certain extent. In addition, Plexturbo supports multiple hard disks to set up memory acceleration, and supports a total of 16 GB of memory as the acceleration of the SSD. If you want a better experience unless your memory is large enough, you can intercept more memory. In fact, some people may ask, the memory itself is not enough to give back a point to SSD acceleration, is not too economic, in fact, Plexturbo and Ramdisk, FacnyCache, etc. are still some differences, Plexturbo is dynamically intercepted memory, which means that when the hard disk needs to read It will be used when it is used, and it will return to the system memory when idle, but the official recommendation is that the memory should be no less than 4GB, preferably 8G or 8G or more, and the system must win7 and above to support Plexturbo. Black Technology PlexCompressor Technology:
Black Tech PlexVault:
PlexVault technology is to hide disk technology, a part of the SSD as a secret disk, you want to open this secret disk can only be hot-key activated, and then enter the password will appear on the computer, and when the PlexVault is hidden, you can not penetrate Pass Device Manager, Disk Administrator, File Explorer, or Add Remove Programs/Programs and Features to find the existence of PlexVault. Really ensure that your secret files will not be discovered by others. 
Before you set up your PlexVault, you need to set up a hotkey to start. To be safe, you can set up two groups to avoid forgetting. 
After setting hotkeys to PlexVault size allocation and volume label and password, the 128GB M7V can only set up 8GB of hidden disk space 
After starting, the system will remind you that it has started 
After the start, there will be an H drive, and then click to see what you want to see. 
Car Ethernet is a new local area network technology that uses Ethernet to connect the electronic unit in the car. Unlike traditional Ethernet, which uses 4 unshielded twisted pair cables, car Ethernet can achieve a transmission rate of 100Mbit/s or even 1Gbit/s on a single pair of unshielded twisted pair cables. At the same time, it also meets the requirements of the automotive industry for high reliability, low electromagnetic radiation, low power consumption, bandwidth allocation, low latency and synchronous real-time. The physical layer of on-board Ethernet uses BroadRReach technology, and BroadR-Reach's physical layer (PHY) technology has been standardized by the One-pair Ethernet Alliance (OPEN). Therefore, it is sometimes called Broad RReach (BRR) or OABR (Open Alliance BroadR-Reach). The MAC layer of vehicle Ethernet adopts the IEEE 802.3 interface standard and seamlessly supports widely used high-level network protocols (such as TCP/IP) without any adaptation.
On-board Ethernet protocol architecture
Vehicle-borne Ethernet and its supported upper-layer protocol architecture are shown in Figure 1. Vehicle-borne Ethernet mainly involves OSI layer 1 and Layer 2 technologies, while vehicle-borne Ethernet also supports AVB, TCP/IP, DOIP, SOME/IP and other protocols or application forms.
On-board Ethernet framework
Among them, AVB is an extension of traditional Ethernet functions, which enhances the real-time performance of traditional Ethernet audio and video transmission by adding precise clock synchronization, bandwidth reservation and other protocols, and is a network audio and video real-time transmission technology with great development potential. SOME/IP (Scalable Service-Oriented MiddlewarE on IP) specifies the video communication interface requirements for vehicle camera applications, which can be applied to the field of vehicle cameras, and realizes the mode control of driver assistance cameras through apis.
As an extension of AVB protocol, Time-Sensitive Networking (TSN) introduces related technologies of time-triggered Ethernet, which can efficiently realize the transmission of automotive control information. In addition, the on-board Ethernet of the 1Gbit communication standard also supports Power Over Ethernet (POE) function and Energy-Efficient Ethernet (EEE) function. The POE function provides power for connected terminal devices while transmitting data through twisted pair cables, eliminating the need to connect external power cables to terminals and reducing the complexity of power supply.
On-board Ethernet standardization
In terms of in-vehicle Ethernet standardization, the IEEE802.3 and IEEE802.1 working groups, AUTOSAR, the OPEN Alliance and the AVnu Alliance have played a major role in promoting it.
The IEEE802.3 local area network standard represents the mainstream Ethernet standard in the industry, and the on-board Ethernet technology is developed on the basis of IEEE802.3, so the IEEE is currently the most important international standardization body for on-board Ethernet. In order to meet the requirements of the car, it involves the development of a number of new specifications and the revision of the original specifications within the two working groups of IEEE802 and 802.1, including PHY specifications, AVB specifications, and single-wire to data line power supply. In addition, AVB related to AV transmission, timing synchronization and other specifications also need to be standardized by other technical committees of IEEE, such as IEEE1722 and IEEE1588.
OPEN Alliance
The OPEN Industry Alliance was launched in November 2011 by Broadcom, NXP, and BMW to promote the application of Ethernet-based technology standards to in-car connectivity. The main standardization goal is to develop a 100Mbit/s BroadR-R physical layer standard and develop OPEN interoperability requirements.
AUTOSAR
AUTOSAR is a consortium of automotive manufacturers, suppliers, and tool developers that aims to develop an open, standardized automotive software architecture, and the AUTOSAR specification already includes the automotive TCP/UDP/IP protocol stack.
AVnu
The AVnu Alliance was formed by Broadcom in collaboration with Cisco, Harman and Intel to promote the IEEE 802.1 AVB standard and the Time Synchronization Network (TSN) standard, establish a certification system, and address important technical and performance issues such as precise timing, real-time synchronization, bandwidth reservation, and traffic shaping.
