What is Harddisk / 什么是硬盘

Harddisk

Alternatively referred to as a hard disk drive and abbreviated as HDD or HDD, the hard drive is the computer's main storage media device that permanently stores all data on the computer. The hard drive was first introduced on September 13, 1956 and consists of one or more hard drive platters inside of air sealed casing. Most computer hard drives are in an internal drive bay at the front of the computer and connect to the motherboard using either ATA, SCSI, or a SATA cable and power cable. Below, is an illustration of what the inside of a hard drive looks like for a desktop and laptop hard drive.

或者简称为硬盘驱动器，简称为HDD或硬盘驱动器，硬盘驱动器是电脑的主要存储介质设备，永久存储在电脑上的所有数据。 1956年9月13日，首次推出的硬盘驱动器由一个或多个硬盘驱动器盘片内部的空气密闭容器内。大多数的计算机硬盘驱动器在内部驱动器托架在电脑前和使用无论是ATA，SCSI或SATA电缆和电源线连接到主板上。下面，就是一个例证内的台式机和笔记本电脑的硬盘驱动器的硬盘驱动器看起来像什么。

** Note : head actuator = 头致动器

read/write actuator arm = 读/写促动臂

read/write head = 读/写磁头

spindle = 主轴

platter = 磁盘

Chassis = 底盘

As can be seen in the above picture, the desktop hard drive has six components: the head actuator, read/write actuator arm, read/write head, spindle, and platter. On the back of a hard drive is a circuit board called the disk controller.

在上面的图片中可以看出，台式机硬盘有六个组成部分：头致动器，读/写促动臂，读/写磁头，主轴和磁盘。在硬盘驱动器的背面一个称为磁盘控制器的电路板。

How is data read and stored on a hard drive?

数据是如何读取和存储在硬盘上吗？

Data sent to and from the hard drive is interpreted by the disk controller, which tells the hard drive what to do and how to move the components within the drive. When the operating system needs to read or write information, it examines the hard drives File Allocation Table (FAT) to determine file location and available areas. Once this has been determined, the disk controller instructs the actuator to move the read/write arm and align the read/write head. Because files are often scattered throughout the platter, the head will often need to move to several different locations to access all information.

All information stored on a traditional hard drive, like the above example, is done magnetically. After completing the above steps, if the computer needs to read information from the hard drive it would read the magnetic polarities on the platter. One side of the magnetic polarity is 0 and the other is 1, reading this as binary data the computer can understand what the data is on the platter. For the computer to write information to the platter, the read/write head aligns the magnetic polarities, writing 0's and 1's that can be read later.

发送的数据和从硬盘驱动器，硬盘驱动器做什么和如何移动的组件，驱动器内的磁盘控制器，它告诉解释。当操作系统需要读取或写入信息时，它会检查硬盘驱动器的文件分配表（FAT），以确定文件的位置和可用区域。一旦这已经确定时，磁盘控制器指示的致动器移动的读/写臂和对齐的读/写头。因为文件通常分散在整个盘子里，头部会经常需要移动几个不同的地点访问所有信息。

传统的硬盘驱动器上存储的所有信息，如上面的例子中，磁性。完成上述步骤后，如果计算机需要从硬盘驱动器读取信息，它会读取盘片上的磁场极性。一侧的磁场极性为0，另一方为1，读取此作为二进制数据的计算机可以理解的，在盘片上的数据是什么。对于计算机将信息写入到盘片上，读/写头对齐，写0和1的后面，可以读出的磁场极性。

The New Powerful Cpu with Ivy Bridge. 新的Ivy Bridge强大的CPU

The intel ivy bridge cpu is starting using number 3 for header example i3-3220/ i5-3450/ i7-3770k

The 22nm-based Ivy Bridge processor is considerably smaller than its predecessor. It has nearly 400 million more transistors yet is about 25 percent smaller. What’s more interesting, however, is how much real estate is dedicated to each task on the new Ivy Bridge vs. Sandy Bridge. These die shots (not to scale) show that the almost 2x performance bump in graphics comes at the price of die space. Intel, however, discounts any criticism regarding how much emphasis it placed on graphics over x86 functionality and says just because it looks like more space was expended on graphics doesn’t mean it’s more important.

英特尔Ivy Bridge的CPU开始使用3号头的例子酷睿i3-3220 /酷睿i5-3450 /酷睿i7-3770k

基于22纳米Ivy Bridge处理器比它的前身是相当小的。它有近400万的晶体管是小约25％。然而，更有趣的是多少，房地产是专门为每个任务在新的Ivy Bridge的与Sandy Bridge的。这些模拍摄（不按比例）显示，几乎2倍的性能提升，在图形来自于模空间的价格。然而，英特尔的折扣任何批评意见，它放置在图形的重视程度超过x86功能和说，只是因为它看起来像图形花费更多的空间，并不意味着它更重要的。

Sandy Bridge

Ivy Bridge

Compatibility 兼容性

We’ve long railed against Intel for releasing new sockets with new CPUs (remember the short-lived Socket LGA1156 and Socket 423 and numerous LGA775 versions?), but the company has stepped up to the plate for the Sandy Bridge-to-Ivy Bridge transition. As Intel promised, most LGA1155 boards will support Ivy Bridge procs if the firmware and BIOS are updated to support the chip by the board maker. However, not all chipsets will make the Ivy Bridge cut. Intel has intentionally left out support for the business chipsets Q65, Q67, and B65 while supporting consumer H61, H67, P67, and Z68. Why leave some out? Intel believes the day of an IT shop getting down and dirty and upgrading processors in an office-drone PC are long gone, so there’s just no reason to expend the resources on unnecessary support. Besides getting the latest core technology from Intel, switching to Ivy Bridge on older 6-series boards should also give you PCIe 3.0 support on some slots.

我们早就抨击英特尔推出新的套接字与新的CPU（还记得短命的插槽LGA1156和Socket423和众多的LGA775版本？），但该公司的Sandy Bridge，Ivy Bridge的加强板过渡。作为英特尔的承诺，最LGA1155主板将支持Ivy Bridge的特效，如果固件和BIOS更新，以支持芯片的电路板制造商。然而，并非所有的芯片组将做的Ivy Bridge切断。英特尔有意冷落业务芯片组Q65，Q67和B65的支持，同时支持消费者H61，H67，P67，Z68。为什么要离开了吗？英特尔认为，当天的IT购物越来越脏，升级处理器在办公室无人驾驶飞机PC日子已经一去不复返了，所以没有理由花费的资源上不必要的支持。除了英特尔最新的核心技术，从旧的6系列主板，切换到Ivy Bridge的也应该给你一些插槽的PCIe 3.0的支持。

World’s First Chip with ‘3D’ Transistors 世界上第一个'3 D'晶片的电晶体

We’ve long dubbed Intel the “Master of the Fab.” The company’s prowess in chip fabrication is the envy of the world. Yeah, there was that little thing with the Pentium 4, which hit the process wall like a freight train, but for the most part, Intel’s mastery of chip fabrication has always made its new CPUs a tour de force of technology that makes you wonder if the company doesn’t have a crashed flying saucer hidden at 2200 Mission College Boulevard.

With Ivy Bridge, Intel again amazes with the world’s first use of tri-gate, or 3D, transistors. Also called finFETs, for fin field-effect transistors, the 3D transistors literally rise up off of the die to dramatically reduce power consumption while increasing performance.

In a traditional planar transistor, current flows on a flat surface like a river. A gate, which ostensibly controls that flow, lies across the top of that river with contact only along a small surface. With a finFET, or 3D tri-gate, the flow of power spans a fin that juts from the surface. Instead of just contacting the surface along one dimension, the gate encircles it and makes contact on three sides.

我们早就被称为英特尔的Fab“大师”该公司在芯片制造的实力是全世界羡慕的对象。是啊，有那个小东西的奔腾4，它打的过程墙壁像一列货运火车，但在大多数情况下，英特尔掌握芯片制造一直由它的新的CPU一游德力科技，让你不知道，如果该公司没有在2200使命学院大道隐藏坠毁的飞碟。

随着Ivy Bridge的英特尔再次惊讶与世界上首次使用三栅极，或3D晶体管。也被称为FinFET元件，鳍式场效晶体管，三维晶体管从字面上上升关闭的模具，在提高性能的同时，显着降低功耗。

在传统的平面型晶体管，电流流过，像一条河流，在一个平面上。一个门，表面上控制流量，横跨该河的顶部，只能沿着一个小面的接触。有了一个的finFET，或3D三栅极的电源时，流程跨越从该表面伸出的翅片。而不是仅仅沿一维的表面接触，栅极包围它，三面接触。

What is RAID? 什么是RAID?

RAID

RAID stands for Redundant Array of Inexpensive (Independent) Disks

In most situations you will be using one of the following four levels of RAIDs.

RAID 0
RAID 1
RAID 5
RAID 10 (also known as RAID 1+0)

This article explains the main difference between these raid levels along with an easy to understand diagram.

In all the diagrams mentioned below:

A, B, C, D, E and F – represents blocks
p1, p2, and p3 – represents parity.

RAID LEVEL 0

Following are the key points to remember for RAID level 0.

Minimum 2 disks.
Excellent performance ( as blocks are striped ).
No redundancy ( no mirror, no parity ).
Don’t use this for any critical system.

RAID LEVEL 1

Following are the key points to remember for RAID level 1.

Minimum 2 disks.
Good performance ( no striping. no parity ).
Excellent redundancy ( as blocks are mirrored ).

RAID LEVEL 5

Following are the key points to remember for RAID level 5.

Minimum 3 disks.
Good performance ( as blocks are striped ).
Good redundancy ( distributed parity ).
Best cost effective option providing both performance and redundancy. Use this for DB that is heavily read oriented. Write operations will be slow.

RAID LEVEL 10 （1+0）

Following are the key points to remember for RAID level 10.

Minimum 4 disks.
This is also called as “stripe of mirrors”
Excellent redundancy ( as blocks are mirrored )
Excellent performance ( as blocks are striped )
If you can afford the dollar, this is the BEST option for any mission critical applications (especially databases).
