After replacing the SSD under Mac Pro, it is cumbersome to change the SSD to AHCI mode if Win7 is installed. This article describes how to change the SSD in Mac Win7 to AHCI mode driver and the processing of several common problems.How to change the SSD drive mode of Win7 to AHCI when Lion and Win7 dual system coexist1
compared with the desktop, we have a relatively low demand for notebook performance, so in the process of upgrading the notebook hard drive is the pursuit of performance or large capacity, or both? Small series will come up with three solutions to discuss with you.
For the different needs of the user groups, we will be the notebook upgrade program roughly summed up in the following three kinds:
1, mechanical hard disk replacement of large-capacity SSD

4K corresponds to 4096HDD Mode:First, let the SSD run in AHCI mode:AHCI, the full name Advanced host controller Interface, which is the high-level hosting controllers interface, is more suitable for SSD SATA storage device communication protocols than the older "IDE" virtual mode. In AHCI and IDE mode, the SSD's performance gap percentage is around 65%. Therefore, it is recommended that
I. first, review the read and write features of SSD (1) Limited write times; (2) best random read performance; (3) Good sequential read performance; (4) Poor sequential write performance; (5) the random write performance is the worst. In terms of storage, different content of SQLServer has its own unique personality. The following lists TempDB, Data, indexes, and transaction logs respectively.

Disk defragmentation is the Disk Cleanup optimization tool with Windows, when the computer does not install other optimization software, you can directly use Disk Cleanup to solve the miscellaneous files in the hard drive, to ensure the life of the hard disk, but also to improve the operating efficiency of the computer machine. But in the Win7 system, there are many partners want to know that SSD solid-state hard disk cleaning? Here is a small weave t
perhaps SSD (solid state Drive) compared to the mechanical hard drive, the speed rise is really fierce, the computer boot to enter the system from the minute to the full turn into seconds reading time. In fact, the benefits of SSDs is not only in the speed of change, if only hundreds of yuan investment in exchange for these, it is too young!

After the above adjustments, I/O became stable and there was no larger fluctuation.
For the sake of insurance, project A decided to use an SSD-equipped model to migrate the master database, and migrate the 24 slave database 27. After the migration is completed, the SSD and MySQL InnoDB pa
Introduction
Another good feature in SQL Server 2014 is that SSD can be virtualized into a portion of the memory for the SQL server data page buffer. By using SSD to expand the buffer-pool, a large number of random iops can be carried by SSD, thus greatly reducing random iops and page-out for data pages.

How to choose mechanical hard disk and SSD
The giants of the tide we all see in the eyes of pain in the heart, after all, they are accompanied us through a lot of years old brand. And for consumers, in the end should buy large-capacity mobile hard disk products good or fast technology strong (mobile) solid-state drives good?
Why did the traditional mechanical hard disk "fall"?

SSD solid-state hard disk capacity faster?
Theoretically speaking, the larger the solid-state hard disk capacity, the better the IPOs performance, the faster the random read and write speed. In layman's terms, because solid-state drives are made up of multiple storage chips, the larger the capacity, the more chips there are, and the faster each chip reads and writes, but the faster a plurality of chips read and write together.
However, it is worth m
