to do the task of planning inside. And it's free! Supports NTFS and FAT32, supports Windows xp/vista/win7 systems, and new versions support 64-bit systems. Defraggler's command-line version is too simple to use for system resources, without adding system services.I used to think I had to defragment it. The disk's free space should be much more, but I once found that there was a lot less space available after defragmenting the pieces. Later found that the software before the disk defragmentation
A disk tool designed for NT/2000/XP/Vista,

OneView with AS SSD benchmarkIncludes 4 aspects of test (sequential read/write, 4K Random read/write, 64 thread 4K read/write, seek time)
As SSD's main test, but also the most common on the Internet to get test results, is its main interface on the continuous, random, access time, such as 8 related tests, as well as compression and file replication test. Let's start with a brief explanation of how each test is under the as SSD.The first is the c

Here, the prompt is "disabledeletenotify = 0" That is, the trim directive is enabled; "Disabledeletenotify = 1" is the TRIM directive is not enabled, the trim is not turned on, please update the driver and system patch in time.Turn on Trim functionThird, turn off the system recovery function, this function will affect the normal operation of SSD or trim, an
It is well known that the system will cause disk fragmentation after running for a while, which can seriously affect the speed of the system, so Windows system itself provides the defrag command to help users clean up disk fragmentation, Windows 7 is no exception, and Vista is different from windows The defrag in 7 adds more options, with command line versions containing more directives.
Disk defragmentation is a very useful feature, especially for long-used systems, as well as some computers that frequently delete files, and it is necessary for the system to defragment the disk at regular intervals. This allows you to sort out some of the file fragments and delete them.

The only way to open disk defragmentation is to:
Start → All programs → accessories → system tools or right-click C-Drive, select Properties, you can see the Disk Cleanup function.

Windows auto-scheduled defragmentation program.The As SSD test is only a 4K alignment of the starting byte of the partition, but if the sector size below the 4K standard is formatted, the advantage of the 4K sector still cannot be played. Because a disk that supports advanced formatting is read and written in 4 K sectors. “”。。。 In fact, one of the most important functions of the SSD's master chip is to prevent the system from constantly writing to th
Defrag: Defragmentation of disk
[applicable] disk reads and writes many times, or the disk uses the time to be very long, may need to use this commandDefragment the disk. Disk fragmentation does not mean that the disk is broken, but only because of multiple copies and deletionsIn addition to files, disk usage can be very incoherent, causing slower speed.

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?

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

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

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

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

This release of update patch flash STORAGE Firmware update 1.1 is mainly for the 2012 section, there was earlier user feedback that some of the model on the unknown problems caused by the data saved in SSD was erased. If the consumer discovers the problem or cannot install the update on the machine, you can replace the SSD at the local Apple Store for free.
