low, but the speed is slow. Each MLC unit is 2bit, a whole lot more than the SLC. However, due to the large number of data stored in each MLC storage unit, the structure is relatively complex, the probability of error will increase and must be corrected, this action causes its performance significantly lag behind the structure of the simple SLC flash memory. In addition, the advantage of SLC flash memory is up to 100,000 times, 10 times times higher than MLC Flash. In addition, in order to ensu
Reference: http://blog.csdn.net/tianlesoftware/article/details/6009110The main types of hard disk interfaces currently available are IDE, SATA, SCSI, SAS, FC, and so on.The IDE is commonly known as the port, SATA is commonly known as the serial port, both of the hard disk is the PC and low-end server common hard disk.SCSI is the abbreviation for "Small computer system dedicated interface", which is the hard disk with this interface.SAS is the
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.
Understanding SCSI Hard drives:
Every time the SCSI disk is released with a new specification, the SCSI drive then supports the new specification, making the SCSI hard drive a leader in SCSI
hard Disk Interface
The current hard disk interface type is not much, mainly IDE, SCSI, SATA three kinds. Many times the IDE replaces the Ultra ATA, many people are accustomed to the Ultra ATA hard disk is called IDE hard disk, but need to explain that the concept of the IDE is greater than ata--in principle all hard drive integrated controller design belongs to IDE,
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
Many people are not unfamiliar with the installation of Windows 2000, and it is true that there is no difficulty in performing Windows 2000 Setup.exe, upgrades, or direct installations from Windows 98, for the vast majority of users who use IDE hard disks. However, if your computer is a graphics workstation using a SCSI hard drive, it might be a different story.
My Computer is a typical example,
compatible with the PATA device by using a multi-purpose chipset or serial-parallel converter. Because SATA and PATA can use the same drive, you do not need to upgrade the operating system or perform other changes.
5. You do not need to set the jumper of the Master/Slave disk for Sata. The BIOS will number it in the order of 1, 2, and 3. This depends on the SATA connector to which the drive is connected
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
Configure the SCSI tape drive-Linux Enterprise Application-Linux server application information on sunbench iseserver. The following is a detailed description. Not every place that runs Solaris Operating System has backup solution resources, and they do not even need these resources, these backup solutions include automatic replacement of expensive tapes, Tape libraries, or Tape Silo. Generally, you only ne
Not every place running Solaris operating System has the resources to backup the solution, and they don't even need those resources, such as expensive tape-changer, tape library, or Tape Silo. What is usually needed is a backup or ufsdump of the root file system, an important database, or a small development entry code. In these cases, external devices such as SCSI DDS tape drives are usually sufficient.
The following information is useful for config
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
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
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
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!
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
