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 hard disk, micro-hard disk, memory card, USB flash
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 drive letter is not to be judged. The last group of Eric God told LSSCSI Tools
Lenovo ThinkPad E420 installed SSD to the CD-ROM drive bit, the BIOS can not find, PE to find SSD.
Download old peaches PE version installed to U disk, start with U disk, enter WinPE, install system to SSD hard drive, reboot, BIOS can't find
look at the love machine bottom and instructions, find the machine model, and then on Baidu a check will know. Of course, if it is convenient, you can also take down the hard drive to see whether the SATA interface. In the figure below, the left side is the first generation of SATA serial port, Speed 150mb/s. On the right is PATA, the IDE interface disk:
Trick Two, check the Love Machine disk interface type, the correct choice of upgrade
, so the system will be caught in the repeated error correction, but can not repair the dead loop, eventually causing the system to think that the block address is damaged (bad block), but The SSD itself does not remap the physical block address corresponding to these logical block addresses (LBA), so this failure occurs, but the actual storage unit is not corrupted.Some of the new SSD users, encountered th
How to optimize SSD solid-state drive in Win8 system
One, AHCI hard disk mode can improve hard disk performance, determine your solid state drive is running in AHCI mode, specific can be installed in the motherboard BIOS in front of the system set up!
Second, turn on the TRIM function to reduce disk wipe
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 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
For more information about how to use an ssd hard drive to accelerate mysqlindex, see www.javaarch.netjiago ushiindex.htm? If the data volume is large and the ssd capacity is not large, you can save the index data to the ssd to store the table data on the old hard disk .? So how can we make mysql build index on
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
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 spe
flash chips). SSD interface specification and definition, function and use of the same as the ordinary hard disk, in the product shape and size is also consistent with the ordinary hard disk. The new generation of SSDs generally uses the SATA-2 interface. But its cost is higher.One. IDEAn abbreviation for the IDE (Integrated Drive Electronics Integrated driver Electronics), which is intended to refer to th
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 hard disks in sequence.
Sequential read
Test command: FIO-name iops-RW = read-BS = 4 K-runtime
share with you the key points of three settings for SSD drives
The key to opening AHCI is:
AHCI, all called Serial ATA Advanced Host Controller Interface (serial ATA Advanced Master Interface)
The potential acceleration capability of SATA drives, which can increase the read/write speed of 30% hard disk. When installing a solid-state drive, turn on AHCI to give full play to hard
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 there is no mechanical structure, not afraid of collisions, fall, power outages, so small part of the view that the actual use of solid s
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!
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 update the system, first optimize:
Cp/etc/fstab. b
"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 drive is different, low lattice on solid-state hard disk meaningless. Because the low lattice refers to the rewriting of the disk interleaving factor,
Because of work, sometimes two computers are needed to work, and most people engaged in development are those pursuing computer performance, so the laptop is naturally not light, not to mention the two.
I have been suffering from two computers for more than half a year, and finally made up my mind to install a system into a mobile SSD, carrying a non-hard drive computer and adding two mobile SSDS to reduce
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 hard disk space.
3, virtual memory, 4
