[English]
What is this?
- If you have a mac with HDD, and now you want to upgrade to SSD, you need this tool.
What exactly does it do?
This tool will perform several tasks, listed below：
- enable TRIM(*), which will speed up your SSD's writes and extend it's life.
- disable atime, which will speed up your SSD's reads and extend it's life.
- disable SMS, which is useless for SSD.
- reboot automatically.
How to use?
After the SSD and OSX being installed, follow the steps below:
- download this tool to your mac, you can place it in any directory.
- run the script: sudo make -f ssd_opt.makefile
- waiting for executing and reboot.
- check result.
Caution:
- This tool will report "segment fault", but it's OK, just ignore.
- (*)TRIM-tuning sometimes does not work, you should check it as what this article says: http://www.cnbeta.com/articles/219752.htm (chinese)
[简体中文]
Macbook装完SSD后，需要进一步优化，以充分释放性能并提高寿命。
执行方式为：sudo make -f ssd_opt.makefile
优化点包括：
- 打开TRIM，可提升写性能并增加寿命。
- 禁用atime，可提升读性能并增加寿命。
- 禁用磁盘保护，这个对SSD没有意义，白费电。
注意：
- 打开TRIM时，会误报segment fault，忽略即可。
- 由于系统版本原因，TRIM可能打开失败，如何检测成功与否，以及失败了怎么办，请参见：http://www.cnbeta.com/articles/219752.htm
