disco ssd What is the difference between DDR and DDR2 What is he difference between DDR3 and DDR2 [Introduction] solid state drive SSD OEMdisco SSD DDR2 and DDR, respectively 1. Rate and prefetch  DDR2 actually operates at twice the frequency of DDRdisco.” SSD, DDR2 memory has twice the 4-bit expected capability of standard DDR memory. 2. Package and voltage  DDR package is TSOPIIdisco ssd, DDR2 package is FBGA; The standard voltage for DDR is 2.5V and the standard voltage for DDR2 is 1.8V. 3, bit pre-fetch  DDR is 2bit pre-fetch and DDR2 is 4-bit pre-fetch. 4. Introduction of new technology DDR2 introduces OCD, ODT and POST  (1) ODT: ODT is the termination resistor of the built-in core, its function is to make the DQS, RDQS, DQ and DM signals consume at the termination resistance. prevent these signals from forming reflections on the circuit; (2) Post CAS: It is set to improve the efficiency of DDR2 memory; In the absence of the pre-CAS function, the addressing operation of other L-banks may be delayed due to the current line of CAS commands occupying the address line and make the data I/O bus idle, when the pre-CAS is used, the command conflict is eliminated and the interest rate of the data I/O bus is increased. (3) OCD (Off-Chip Driver): Offline drive adjustment, DDR2 can improve the integrity of

The hard disk used to assemble the computer is now divided into two types: SATA’s 3.5-inch traditional hard disk, and the other is the solid-state drive, which is SATA (2.5 inch) and M.2 (PCIe). Please note: saving a disk in another place is not called backup, it is called backup to save one more. your attention is my motivation to keep updating!

The first two issues excerpted the CPU selection memory selection reference in the stand-alone hardware configuration disco SSD, interested readers can click to review. if you want to get the full guidedisco ssd, clickable here Download. 2.5″ SSDs are divided into SATA, SAS and U.2 NVMe interfaces. Currently, SATA 3.0 interface rates are 600 MBps, SAS 3.0 interface rates are 1200 MBps, and U.2 NVMe generally uses PCIe 3.0 x 4 with an interface rate of 3.938 GB/s. NVMe SSD is the fastest, but the cost is relatively high, SAS SSD price is also more expensive, the same investment, not as good as the purchase of NVMe SSD brought by the benefit, if from the cost consideration, SAS SSD is not recommended, but if the cost is not considered or the existing equipment is SAS SSD, SAS SSD performance is better than SATA SSD, it is also worth considering the application of SAS SSD. > based on the above, it is recommended that SATA interface SSDs that are still mainstream at present. at least 2 blocks. The first two

nvme ssd What the! NVMe does not support TRIM? You can’t go wrong with it… ddr 4 8gbSSD OEM nvme ssd is nvme ssd, you read that right nvme ssd， NVMe’s SSDs do not support TRIM! what’s going on here? a little bit about the development of SSDs. SSDs were developed during the SATA era. The original SSD speed was slow and the unit price was high, and the sequential read and write speed was not as fast as the hard disk. However, the iterative development of semiconductors is very fast, and soon catches up with and surpasses ordinary hard disks. but at that time, the SSD still used the SATA interface, because the storage at that time was the world of SATA HDD, if your SSD is not compatible with SATA, who is it sold to? < p data-pid = “yqHA11jM”> SSDs are inherently different from HDDs. What are the essential differences? here, the first is the advantage of the SSD, and the second is the characteristics of the SSD. The third is the fatal flaw of SSDs. so, the SSD is at the time of writing. The strategy adopted is to read out the blocks that need to be overwritten, make data modifications, and then write them to a new, erased place. Eventually, garbage blocks are periodically recycled and erased inside the SSD.

laptop rams Should PS4 SILM replace the SSD? m2SSD OEM laptop rams themselvesPS4 SILMlaptoprams, Friends of other models are for reference only. first of all, I can replace it with an SSD laptop rams, there is no need to force it if you have no spare money. my original hard drive was Toshiba 500G HDD, and the first game I played was Qui Ye 4. At the beginning of the game, I don’t think it is good, and the loading time is acceptable. But after playing to the Lake of the Nine Realms, you can’t stand it, because the enemies that start here begin to become stronger, and the FPS-style operation method is very painful, and often two or three miscellaneous soldiers can kill you. And every time I died, I would reload it for more than ten or twenty seconds, and I almost threw the handle away. so I took the Western Digital 240G SSD disassembled and mounted on PS4. However, it also encountered a very depressing thing – the PS4 system directly ate the 70G hard disk, and only 170G was available for 240G. count, anyway, are installed, how to say first try the effect. Overall, the effect, although not as obvious as a PC, is visible to the naked eye. Although there is no calculation time, the time to visually boot up

ssd 512gb Some Insights on SMR Technology for HDDs hard drivesSSD OEMssd 512gb Since everyone’s impression of SMR’s hard disk is not very goodssd 512gb, so I will introduce you to some knowledge of SMR technology. stacked tile (SMR) hard drivessd 512gb, as the name suggests, the tracks of the hard disk are fastened to the previous column like tiles. This technology can effectively improve the TPI of HDDs and greatly improve the capacity of hard disks. But this model will also bring some annoying problems, such as the reliability that many people reflect, which is more prone to failure… (Actually, I have not used SMR hard disk) stacked tiles, let’s talk about how the hard disk stacks tiles. First a brief diagram Traditional writing can be seen that it is okay to write to a sector alone, and writing adjacent tracks has no effect on the data written before; Stacked tile writing, on the other hand, is not feasible. Band is the smallest unit of data written in SMR mode. But this SMR also has a corresponding problem, there is a need to leave space between the two bands, which will also waste space, about 1% of the capacity loss. Now that the capacity of each band is dynamic, the capacity and number of tracks of a band with an outer diameter of a

Hongwang Semiconductor ICMAX focuses on embedded memory for 15 years, and today we will tell you about the past and present lives of mechanical hard disks and solid-state drives. (ICMAX SSD, image source, ) Past life mechanical hard disk: Since mechanical hard disk technology predates the birth of solid-state drives, the first mechanical hard disk is also the world’s first hard disk. The world’s first hard disk was born in 1956, designed and manufactured by IBM, its name is IBM 350 RAMAC, the early mechanical hard disk is huge, and its mechanical structure is relatively backward and rough in our current view. After nearly 30 years of development, it was finally in the late 80s that the 2.5-inch HDD we know was born. SSD: compared to mechanical hard disks, SSDs appear much later. The world’s first SSD was born in 1976, designed by Dataram, and the SSD, with a capacity of 2MB,

Next articleLearn about “one” DRAM arrays should actually be called arrays, while DRAM arrays should be called subarrays, and the subarrays are also composed of MATs. the above is “one” comment area pointed out, this I really don’t know, today I checked it out indeed。 bulk ssd hard drives SSD OEMssd 500gb

SSD Does DDR Design Need a Back Drill harddriveSSD OEMSSD Back drill SSD, believe to engage in PCB design or processing friends will not be unfamiliar. We know that SSD, this process has now been widely used in the design of high-speed serial channels above 10G, its role is mainly to solve the problem of sharp attenuation of high-frequency energy caused by the long vias stub, the smaller the vias stub, the higher the frequency band of sharp attenuation, so we will focus on it in high-speed design. We can also obtain the relationship between stub and the back-loss insertion curve through 2-dimensional or 3-dimensional simulation of vias, as shown in the following figure: harddriveSSD OEMSSD
