This article has a total of four parts:1. Description of Macbook Pro2. Pre-Preparation3, formally began to replace the SSD4, the system installed on the SSD5. Problems that ariseMacbook Pro Scenario Description:
My MBP is 12 years in the 13-inch MBP low, in the rise of 10.10 after the card does not work, so ready to change the CD-ROM drive to SSD, and then upgrade the memory bar;
Pre-Preparation 1, determine the number of SATA CD-RO
Some time ago in developing a system that uses SSD for caching, a large amount of disk caching occurs when writing data at high speed. Too much disk caching is very dangerous if there is a problem with the machine if it is not written to disk in a timely manner, which can result in a lot of data loss, but if the data is brushed into the disk in real time, the write efficiency is too low. In order to understand the Linux system of this disk write chara
Do you want to partition your SSD? Some people say that SSD is best not to partition, will affect the use of performance and life, is this so? On the SSD is good or not partition good, is a more interesting question, which will involve a lot of SSD related knowledge, the following small series to detailed introduction.

From the advent of SSDs, to the present popularity, in fact, only a few years of time. During this time, SSD performance and capacity, especially the price, have undergone a great change. Have to say, now the capacity of SSD is getting bigger, the price is also getting cheaper. However, compared with the traditional HDD, there are some gaps in the capacity and price ratio, especially the large capacity is t

Today, this article mainly with the introduction of SSD solid State hard drive optimization of some knowledge, mainly for some netizens often said they buy the solid-state hard disk speed is not fast, or feel that the SSD and traditional HDD hard drive gap betwe

That being the case, we can see that improving the performance of the hard drive can improve our experience of using the computer, so SSD turned out. SSD because of its storage medium and principle and traditional mechanical hard disk is completely different, so greatly improve the read and write s

The use of SSD hard disk is becoming more and more common, its powerful performance can help the computer to improve the system and software running speed, so by many users, but a lot of computer novice for how to install SSD hard disk still have many questions, the following small series will explain the SSD hard disk installation method.
I talked to users and vendors about how SSD (solid state drive) is used, I found that most people think that server SSDS must be ultra-high-performance SLC (single-layer unit) PCIe flash cards manufactured by manufacturers such as Fusion-IO, micron, Virident, or LSI. Although most people know that the mainstream SAS or SATA interface SSD is in the 2.5 inch format, they seem to think that these devices are o
Failure phenomenon:
Some of the ThinkPad preinstalled mSATA SSD shipments do not have the Expresscache software installed, resulting in the inability to use the mSATA SSD as a cache.
Impact Range:
-The above problems may occur on the following models, but not limited to the following models:
ThinkPad T430, t430i, t430s, T430si, T530, t530iThinkPad W530ThinkPad X230, x230i, X230 tablet, x230i tabletThink
in recent years, with the popularity of SSD, high-speed solid-state hard disk has become the standard of computer hardware gradually. SSD Solid state hard disk solves the traditional mechanical hard disk reading speed bottleneck problem, bring more fluent experience, computer switch machine obviously speed up, browse the Web page smoother, large-scale application and game load faster and so on, experience i
ImpressionsToday, I tested the model of my own training, and YOLOv2 done a comparison, the detection is correct, YOLOv2 version of the accuracy is not high, but there are a lot of SSD did not detect, recall rate is not high. Note that the SSD environment is Python3, and running on the python2 will be problematic. TENSORFLOW-GPU, OPENCV installation reference my blog: SS
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
files are in use. DiskSim is initially separated from a large, system-level simulator, so it can be easily transplanted to the entire system simulator (such as porting to SimOS ).
What DiskSim Does Not Do?DiskSim only simulates and reports storage subsystem performance-related aspects. It does not simulate the behavior of other computer system components, or the interaction between components and the storage system.
DiskSim simulates the performance of the hard disk system, but does not save th
in sequential read and write performance, sequential reading can reach the 82.4mb/s, basic and mechanical hard disk performance level, the random read and write performance slightly improved, not very obvious. Considering the high requirements of TC for Random Read and write performance, the USB drive with 3.0 interface is still difficult to meet the performance requirements.2.3 Test Result AnalysisCombined with the above test results, slow write speed is the main performance bottleneck of the
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.
