In RAID 1, write access is generally slower than read access. This is because data must be duplicated on two drives during a write operation, which requires more time than reading from either drive, where data can be accessed simultaneously. In contrast, read operations can take advantage of both drives, allowing for faster data retrieval. Thus, while RAID 1 offers redundancy for data protection, it does not enhance write performance.
Reducing access and read time. Providing redundancy.
RAID technology uses multiple disk drives to achieve either fault tolerance or an increase in read and write performance.
Access time is the time it takes for the processor to access the device to read or write to / from it. To put it in more human terms: Which is faster, a train that takes 60 minutes to reach its destination, or a train that takes 70 minutes to reach its destination? The first one, obviously. The access time of 60ns will be faster than access time of 70ns
Read, write, execute, and functions in software objects.
cl3 CL - CAS Latency (column access strobe) refers to the number of clock cycles taken to read or write a column of data off a memory module. The lower the latency, the faster the read/write. RL - Row access strobe Latency (RAS Latency), similarlly, measures cycles taken to read\write a row of data.
It depends on which RAID you mean: software or hardware. For hardware RAID read manual for your motherboard, for software RAID read software help.
First of all, its 'meant'. Now, to answer your question: Faster speed = faster read = faster access.

Name says major difference between both. by the way Software RAID is created using feature provided by Operating System or any special software, but Hardware RAID is created using Hardware RAID controller Card. When you create RAID you are adding overheads to read and write operations. If you create software RAID and your server is too busy or you have many read and write operations you will see there is impact on performance. When you create HARDWARE RAID you will use dedicated controller with processor and some cache. This will not create overhead for your OS and you will find better performance. Software RAID will save some money for you but Hardware RAID will provide you value addition.

RAID is short for Random Array of Independent Disks and is used to manage how data is stored on multiple hard drives on ones computer. Its purpose is to improve read and write speed.
Hard drive speeds of 7200rpm allow for it to read/write/copy data faster, but this doesn't necessarily mean it will open programs faster. If you want to run programs faster, upgrade your computer's RAM (random access memory or usually just called memory).
