3 ways to easily get started with SSD-mounted Win7 systems Technical analysis of "advanced format" SSDs use "Advanced format" technology. Mechanical hard disk in the storage of data, has been the 512byte size of the sector (Sector) for the division to read and write, the hard disk industry decided to expand the sector capacity to 4KB. Simply put, if the SSD 4K storage format is not aligned, it is possibl

West number hard drive 25PROM write after death without the programmer. Next Write Method: To find a board of Seagate, preferably a S15 board (originally with ROM), no other board can be used, but note to add a 4.7K resistor in the main control of the 2nd foot can be written. 1, the ROM to be written by the corner of the position check welding. (Change the plate to weld resistance) 2, into the PC3000,ST function module (error can ignore it), you can, to the 4, 5 feet short-circuit in. 3, cli

Linux to get the current directory, you need to execute the following command: $ (CD ' DirName $ ';p wd) which DirName $, get the parent directory of the currently executing script file CD ' DirName $ ', enter this directory (toggle current working directory) PWD, display the current working directory (after CD execution) This should be noted in the course of use:The command "'" is not a single quotation mark in English, but an English input met

SSD win7 Optimization guide: nine Win7 SSD optimization methods with the price of solid-state drives falling, solid-state drives are now widely used, and some new notebooks and assembly computers are also beginning to adopt solid-state drive platforms, not to mention that the use of solid-state drives has become standard, Although the SSD is fast, but does not un

One, SSD (solid State hard disk) is what side sacred SSD is mainly divided into the following two categories: SSD based on Flash: Flash chips are used as storage media, which is what we usually call SSDs. Its appearance can be made into a variety of touch samples, such as: Notebook hard disk, micro-hard disk, memory card, USB flash drive and other styles. The b

　　SSD Solid State hard disk installation steps 1, first SSD with 2.5 inch to 3.5-inch hard disk rack installed to the hard disk bit. 2, the boot into the BIOS, the disk mode is set to AHCI mode (basically all motherboard's default disk mode is IDE mode, this is to the mechanical hard drive to provide compatibility, but not at all suitable for SSD). Meanwhile, t

4K Alignment is a very important operation when the SSD is partitioned, if there is no 4K alignment, it will result in the cross region reading and writing, not only affect the speed of solid-state drive, but also affect the SSD life. So, how do solid-state drives look like 4k aligned? Method One: Do not use any tool to view the method 1, first use "win + r" combination shortcut key to open th

solid-state drives, choose SLC, MLC, TLC where to go? Because the MLC structure of the flash chip price is relatively moderate, the service life and the rate is quite good, on the current market structure, most SSDs are using the MLC Flash chip architecture.Although the SLC, MLC, TLC chip architecture rate is very different, but relative to the traditional mechanical hard disk, are the quality of the soaring, so I recommend different people to use different flash chip architecture of solid-stat

1, the replacement of solid state hard drive (SSD) First turn off the computer, then remove the mobile battery (note: There are two batteries, the inside and together), unscrew the screws, open the back cover can be opened after the image: Only need to take away the hard drive, remove the need to unscrew a screw, and then replace the solid State Drive (SSD) can be. 2, change the memory strip Because

SSDs are structured and run differently from traditional hard drives, and are strongly recommended after purchase to achieve optimal operational performance and extend the life of the SSD. The first part of the following is some of the things you can find on the internet about SSD drives, which have been introduced a lot, We will not go into the details here.
