SSD SSD Usage Considerations

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. For more information, please find the relevant content on the Internet. The second part is I in the combination of various aspects of the comments, my own summary of some considerations, for your reference.

The first part:

Need to open AHCI in the BIOS
4K alignment required (partition start offset alignment, divisible by 4096, partition by 4K as minimum allocation unit)
It is best not to divide multiple partitions (the SSD mechanism determines the longevity). Some of the online posts suggested, not sure there is no reason, I am referring to a lot of posts also think that this should be the SSD master chip will do a full "wear balance", the logical partition of the operating system will not affect the life of the SSD.
Turn off the 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 the same chunk, which is called the "wear balancing" algorithm ... “

Part II:

===============
1. It is not recommended to use the system's "defrag" to close scheduled tasks in the beginning, attachments, and defrag. SSDs have an advantage over random access to files, unlike the way traditional hard drives are accessed sequentially.
2, run the test tool less use, do a test, the need for a lot of loss.
3, open "Trim" is very important, Win7 above system has supported this.
Trim is a reasonable optimization of the SSD to reduce the speed of its performance degradation. There are many ways to open trim on the web. See if your system has the Trim method turned on, command line mode input fsutil behavior QUERY disabledeletenotify? The resulting disabledeletenotify = 0 means enable
4, select High-performance power mode.
5, the necessary 4K alignment, and the cluster size of 4k integer times the partition format, that is, 4K partition.
6. Select Enable AHCI mode in BIOS.
7. Use the native SATA3.0 interface.
8. Turn off System Restore.
9. In the Control Panel, modify, and then cancel the check box before each item, and then click Re-index (so that you can delete an existing index). Then, in the Windows service, close the Windows Search service.
10. Control Panel, add Remove Programs, remove the Windows system comes with useless tools (games, Windows Search, TABLETPC build, etc.)
11. Turn off automatic upgrades.

Online Questions and Answers:
===============
1. I see many online posts, some people say that solid-state drives do not need to partition, the impact of read and write functions, some people say the SSD needs to partition, can be used to like the previous mechanical hard disk, easy to find files, in addition to a partition of the file corruption, does not affect other partition files.
I want to ask everyone, SSD partition after ... such as a 240G solid-state drive, divided into 2 zones, a 100G, a 120G (the rest of the 20G for the moment) then, will 100G partition damage faster? Because I think, after the partition, the SSD in this section of the file, the number of erase is not only used in this partition flash particles? Or does the SSD's master chip ignore the presence of partitions, balancing all the particles on the entire hard drive?

2. How to convert 100TBW? "SSD, he said durability rating (Lifetime Write): 100TBW"?
Write 100T data in total, provided that all chips are used on average. Flash memory chips have a lifetime of erase times.
In fact, it is not possible, the portion of the data that has been saved is not moving, only the remaining space is repeatedly erased. So the smaller the remaining space, the faster it hangs.
