sas drive vs ssd

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

According to the order list, the HP rx2660 minicomputers in various cities are configured with 4 146 gb sas 10 k 2.5 inch hard disks. When the operating system is installed, two disks are automatically made into RAID 1, the principle is to prioritize hard disks with a large slot number (from left to right, such as 1, 2, 3, 4, 5, 6, 7, and 8 ). Check whether the host's built-in hard drive has been made into

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

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

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!

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

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

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

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 small, and the price than mechanical hard drive to have no advantage, compared to ordinar

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 operation, extend the flash life of solid sta

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 the chip during non-peak read/write times. T

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 and restore to a new solid-state drive;2. Re

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 hard drive options, including 32 GB and

To the introduction of solid-state drives, compared to the old mechanical hard drive, SSD solid state hard disk is said to be the same as the rocket speed, the installation of solid state hard drive after the Win7 system, whether the boot or operation has a quality upgrade, but many friends may not know, the use of solid-state drives there are some need to know t

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 capacity SSD
