The data interface of the hard disk is mainly IDE (PATA), SATA, SCSI, SAS, optical fiber and so on. Among them, SCSI, SAS and fiber and other interfaces are mainly used for servers and workstations, for desktop-grade products, mainly PATA and SATA-based, Pata is what we often say the 80-pin IDE interface, currently has PATA100 and PATA133 as the mainstream products, but in SATA2 ( SATA 3gb/s) interface HDD has been gradually fading out of the market under large-scale popularization. Therefore, f
capacity of 160GB and 250GB, with the wide use of vertical recording technology, hard disk capacity has increased, the world's largest single disk capacity reached 1TB, and 400GB and 320GB, such as large capacity has been in the market everywhere, 320GB product market has been quite mature, The price is also very reasonable. (currently on the market, the minimum capacity of hard disk 80GB, the average sing
should also have similar performance, but GP100 and GP104 in the double precision unit circuit is very different, so the size of the transistor compared to GTX 980 of the 5.2 billion will not increase by as much as a small number of people guessing about 708 billion transistors, the core area of 300-350mm2 around. (Update: The number of transistors is 7.2 billion, the core area is still uncertain.) )
thanks to advanced technology, GTX 1080 video card core frequency is very high, the base has
Ghost HDD Pair CopyAdvantages: Full 100%-copy, including the original operating system can also be used. After the new hard copy is finished, it can be plugged in directly to the computer. Minimum consumption time.Difficulty: For the first operation Ghost to copy of the new, need to strictly control the picture step tutorial. Failure to do so may result in irreversible loss of the original master data.Step One: Open the "to Disk" copy option(1) Preferred to open Ghost tool, enter the interface,
start and end copies of all commands and can easily test the commands and save them at the same time in the script.

disk. If you use a four block 80GB hard disk set to build RAID0 mode, then the disk capacity will be 320GB. In terms of speed, the speed of each individual piece of hard disk is exactly the same. The biggest drawback is that any piece of hard disk failure, the entire system will be destroyed, reliability is only a single piece of hard disk 1/n.RAID1 Technology-Mirror (mirroring)RAID1 is called disk mirroring, the principle is to mirror the data of on
First, capacity
The size of the mobile hard disk capacity is the first choice for many people, usually in GB or TB units, the current market mainstream mobile hard disk capacity has 320GB, 500GB, 1TB, 2TB and so on. The size of the capacity is directly related to the user's storage needs, the choice of mobile hard disk capacity, should be based on their actual needs and product price to decide.
Second, interface type

At the beginning of 2008, we were also happy to launch a variety of 2.5-inch 250GB disks for the mobile platform. In the first quarter of 2009, Seagate (the main product of promotional products) first released the 5400.6 500GB 2.5-inch disk. While there is a big gap between TB capacity and 3.5-inch disks on the desktop platform, it's good news for laptop users to have more storage space. The current mainstream notebook computer, or retail market, 250GB, 320G
Many users in the use of MHDD detection hard drive bad way, there will be some confusion, in the selection of the hard drive serial number that step, you will find that the size of the hard disk is not changed very large, that is, small, in short, is in the detection of hard disk capacity of the size of the hard disk
