One, SSD (solid State hard disk) is what side sacred
SSD is mainly divided into the following two categories:
SSD based on Flash: Flash chips are used as storage media, which is what we usually call SSDs. Its appearance can be made into a variety of touch samples, such as: Notebook
The following switch from Baidu:Recently in preparation for testing, you need to see which machines are mounted SSD hard drives, Google has seen a lot of methods, but all foggy, do not know how to determine. SSD hard disk seems to use the SCSI interface, so according to the name of the
SSD solid-state hard drive How to optimize the use of solid-state hard drives more slowly how to do?
Today, this article mainly with the introduction of SSD solid State hard drive opt
libaio-Direct = 1
RW = read indicates random reading, BS = 4 K indicates 4 K reading each time, and filename indicates the corresponding partition. Here I am/dev/sda6, direct = 1 indicates traversing the Linux Cache
We will test the sequential read, random read, sequential write, and random write speeds of SATA hard disks, SAS hard disks, and SSD
Mechanical hard disk is not limited to read and write times, but the mechanical structure has the service life. and solid-state hard disk in theory, the life is really shorter than the mechanical hard disk, but the actual use of the current solid state drive normal service life has been up to 5-10 years, and because th

PCI-E Interface Solid State Drive
SSD products using the Pci-e interface are relatively small, and the prices of products using this interface are more expensive.

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
This article from http://ssd.zol.com.cn/575/5753057.htmlIn the use of SSD, some users may encounter the computer accidentally power down or crash and forced power outage, the system is abnormal, scan the SSD and found a bad block, and then a hurry to stomp even want to return to the factory repair.In fact, the solid state drive after the bad block is not a seriou
With the price of SSD solid-state hard drives down, later assembled computers to use SSD solid-state hard drive will become mainstream, at present, SSD solid-state hard disk capacity is
"Ideas for solving problems"
When the hard disk appears unable to format, partition, the general method is to initialize the operation. For mechanical hard disk generally using the method of low lattice, but now SSD hard disk and traditional mechanical hard
Key points for using SSD
SSD usage basically does not need to optimize, only the following several places need to note:
1, on the AMD series of Chip motherboards, Intel's SSD performance may be reduced, so you can choose the third party company's products.
2, the Win7 system will be shut off can save a large part of the
that stability is the most important thing.
The/home partition is assigned to the mechanical hard disk. It is a single disk. Because I have 8 GB of memory, there is no need to divide the swap partition, select the following boot drive as the efi partition. You must select this one. Otherwise, the boot will fail after installation... (Personal experience ...)
After the installation is complete, Do not updat
Landlord office computer, originally only configured a piece of mechanical hard disk, with always very uncomfortable, so persuaded the leader to add a block SSD SSD.The operation is as follows:1, the PE under the partition format of the new solid-state drive, the original mechanical hard disk of the C-disk ghost backup
Simple Optimization of SSD hard drive on Ubuntu
1. Set the correct mounting option and enable TRIM.
After Linux is installed, this is very important.
To maintain long-term stability and speed, SSD needs to enable TRIM, which enables SSD to truly erase the materials marked on
Dell is still making different improvements to its most popular netbook Mini10, in addition to the 6-core battery option launched a few weeks ago. In 7th day of this month, the Mini 10 version of the customized Ubuntu system and SSD hard drive was launched, starting at $399. The Ubuntu Mini10 system also provides additional h
solid-state drives in the reading and writing speed significantly less than the other three, the other three versions of SSD solid-state hard disk read and write speed is not large, so the SSD is not full capacity, the faster the speed, In the 64GB and 128GB SSD, the latter speed is obvious, but more than 128GB capaci
Background:ThinkPad X250 Open, shutdown slow unbearable, start Samsung SSD 850 EVO solid state hard drive.

First, the image fileClonezilla to a large hard drive.And then, use GParted to reset the partition size.If not installed, enter the command: sudo apt-get install gpartedRun gparted must require root login, the problem comes. You may not be logged in, prompting you for the wrong password.If you do not forget the root password, the general reason is that the root user does not start, the command: Sudo-i can start it.It seems there is nothing to say, the
Whether for backup or forensics, the cloning of an encrypted hard drive can be accomplished easily using the DD, or disk dump, tool that comes with all POSIX-based operating systems. as a raw disk writer, DD takes all of the information on the hard drive,Bit by bit, and clones it in identical form on another disk. the
