SSD Optimized Operation 1

  1. Brush (SSD) official latest firmwar

Firmware not only directly affects the performance and stability of SSD, but also affects the lifetime of SSD. Excellent firmware includes advanced algorithms to reduce unnecessary writing of solid-state hard disks, thereby reducing the wear of flash memory chips, maintaining performance and prolonging the lifetime of SSD. So it is very important to update the latest firmware released officially in time. There are two general methods to update the firmware of solid state hard disks: using software updates in Windows environment and establishing startup disks (u disks, CD-ROMs) updates.

SSD

  1. Open TRIM Directive

SSD will be used more slowly, which has a lot to do with how they work. Solid state hard disks are new, in which NAND flash memory has been erased beforehand, so data can be written directly to the flash without completing the data cleanup step, when data is written very quickly. As time passes, less and less storage space is never used in SSDs. Many times, data in flash must be erased before it is written, so its performance will degrade significantly.

On Windows 7, after launching a Trim command on an SSD that supports Trim commands, the operating system can tell the SSD master that the data block is no longer needed after deleting a file or formatting it. When some files are deleted or the entire partition is formatted, the operating system sends Trim instructions along with the logical address updated in the operation (Logincal Block Address) to the SSD master (which contains invalid data addresses) so that invalid data can be emptied in subsequent Garbage collection operations, reducing write amplification and improving performance.

Trim instructions are turned on by default in Windows 7. If you want to query the current state of Trim instructions, we can enter the command prompt interface with administrator privileges, enter “fsutil behavior QUERY DisableDeleteNotify”, and then get feedback on the query status. There, the prompt is “DisableDeleteNotify = 0”, where the Trim directive is enabled; The prompt “DisableDeleteNotify = 1” means that the Trim directive is not enabled. It is also important to turn on the AHCI mode within the motherboard BIOS. Because the native order queue characteristic (NCQ) in AHCI optimizes the order in which users send instructions, it reduces the mechanical load to improve performance.

Check the Device Manager-IDE ATA ATAPI Controller, if AHCI is turned on, the controller will be prompted later, if not not.

  1. Safe Erase

The ATA Secure Erase command can be used to clear all user data on the disk, and it will return the SSD to factory performance (optimal performance, minimum write amplification). However, the effect is only temporary, because later use, write amplification will slowly increase back, and eventually return to a stable state. However, when a solid-state hard disk is in use for some time, with messy files and poor performance, it is also necessary to do a safe erase (and re-install the system anyway).

At this time, there are many software available to provide ATA security erase instructions to reset disks, most notably HDDErase. However, for SSD, resetting once is equivalent to completing PE once, so it is not recommended that you do frequent erase optimization there. The operation process is also roughly to change the starting order of the motherboard BIOS to CD-ROM or U-disk priority, then insert the boot device with the software stored, enter the boot interface, and operate as prompted.

In addition, the Intel SSD Toolbox is the latest management tool for Intel SSD solid state hard disks, which is officially launched by Intel. It also contains optimization functions. It works similarly, but because it is software, it is easy to operate.
