The comprehensive performance aspect (data security and speed aspect), certainly is the RAID5 is good, the data reads aspect, the RAID1 is fastest, the data security aspect, the RAID1 is best, the data writes aspect, RAID0 fastest. RAID5 combines these advantages. Understanding Disk Array RAIDFirst, function1 High speed access to disk (speed-up):
Let the SSD speed fly. Solid state HDD Optimization techniques Daquan However, the other aspects of SSDs are obvious, so it has become the necessary hardware for most users installed. In terms of usage, SSD is slightly different from the traditional HDD, and it is necessary to go through a series of settings if the 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
Use the DD command in Linux to test the read/write speed of USB and SSD hard disks.Disk Drive Speed The disk drive speed is measured by the amount of read/write data per unit of time. The DD command is a simple command line tool that can read and write any data block on the disk and measure the read/write
In terms of overall performance (data security and speed), RAID5 is certainly better; in terms of Data Reading, raid1 is the fastest; in terms of data security, raid1 is the best; in terms of data writing, raid0 is the fastest.
