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 serious problem, the following the author of this q

Latency of next-generation SSD controller based on low-density Inspection Author: Stephen BatesLatency Variability In the previous blog, I talked about how the Error Correction Code (ECCS) in the enterprise-level SSD controller is being converted to Low-Density Parity Check (Low-Density Parity Check. This article also implies that this conversion will have a profound impact on the latency in the next-genera

compatibility with Sata hard disks. SAS interface technology is backward compatible with Sata. In terms of interface standards, Sata is a sub-standard of SAS. Therefore, SAS controllers can directly control SATA hard disks, but SAS cannot be directly used in Sata environments, because the SATA controller cannot control the SAS Hard Disk SSD SSD is a technology that discards traditional magnetic me

I bought my first SSD more than 5 years ago (late), for my white MacBook Core2duo 2.0 Ghz. It May is needless to say that my MacBook ran faster than many MacBook Pro's at that time. The look on peoples faces when they saw my MacBook boot faster than their MacBook Pro is unforgettable.By, time I was also experimenting with running 2 x 8GB CompactFlash with SATA converters in RAID-0 mode in my complete Ly silent (but old and under-clocked) Pentium 3 Lin

I updated my old ThinkPad t410i laptop six months ago and purchased the Intel SSD 330i 240G in the Amazon sea in the United States. PS: The purchase price of USD 129.99, now the latest 335i 240G almost to USD 200, SSD true value. ) Recently found in the Windows 8 64bit operating system, the password need to wait until 1-2 minutes to enter the system, long wait for Microsoft's loading, sleep wake up after t

1. The master chip is the core of SSD and determines the performance and stability. Mainly include Intel, JMF, Samsung, Indilloud, among which intel and Samsung are the leader, indilloud is the new expensive, and JMF is mainly oriented to low-end markets. 2. the cache chip assists the master chip in data processing to improve and stabilize performance. Some low-end products will save the cache dram chip for cost reasons. 3. NAND Flash chips mainly inc

Disk defragmentation is the Disk Cleanup optimization tool with Windows, when the computer does not install other optimization software, you can directly use Disk Cleanup to solve the miscellaneous files in the hard drive, to ensure the life of the hard disk, but also to improve the operating efficiency of the computer machine. But in the Win7 system, there are many partners want to know that SSD solid-state hard disk cleaning? Here is a small weave t

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! SSD structure is relatively simple, there is no rotating disc, ma

Let's look at the difference between SSD and traditional mechanical hard drives. The following figure can be seen, the traditional mechanical hard disk by the disc, magnetic head, rotating shaft, control motor and other parts, working disc rotation, magnetic head positioning in the disc at the designated location for reading and writing operations, in a sense and the structure of the old phonograph similar. The advantages of traditional hard disk are

Introduction Another good feature in SQL Server 2014 is that SSD can be virtualized into a portion of the memory for the SQL server data page buffer. By using SSD to expand the buffer-pool, a large number of random iops can be carried by SSD, thus greatly reducing random iops and page-out for data pages. SSD as buf

How to choose mechanical hard disk and SSD The giants of the tide we all see in the eyes of pain in the heart, after all, they are accompanied us through a lot of years old brand. And for consumers, in the end should buy large-capacity mobile hard disk products good or fast technology strong (mobile) solid-state drives good? Why did the traditional mechanical hard disk "fall"?
