If I have a single big capacity hard drive then why to use RAID instead of Hard drives?
RAID Recovery Frequently Asked Questions - FAQRAID (Redundant Array of Inexpensive Disks) systems are faster and more durable than single large hard disk drives. A RAID system stripes or mirrors your data across multiple hard disk drives. Therefore, when you access your data, all the disks are working at the same time, giving a major increase in speed. The RAID hardware controller also contains a large memory cache which dramatically increases performance.
Related QuestionsI have mirrored/RAID hard drives. Won't that protect me from viruses or data loss?
Support - Frequently Asked QuestionsNo. Mirrored hardware only protects you from a hardware failure. Since 90% of data loss is due to data corruption or user error, mirrored equipment offers no protection. This is because corrupt data is instantly written to the mirror equipment. The only way to protect your data is by having a backlog of backups to restore from.

supportCreating an array will erase all data on existing drives. You must save or back up data on all drives before using them in a new array configuration. The rebuild can fail because of a bad sector on the source drive. If this happens try the rebuild again using the "Force Continue on Source Errors" (in 3DM) or the "Ignore ECC" (in the CLI) option. After the rebuild completes you should run a file system check.

Question 2: How large a capacity of hard disk drive can NT support?
Frequently Asked QuestionsAnswer: NT can view a maximum partition size of 2 terabytes (or 2,199,023,255,552 bytes), however there are limitations that restrict you well below this number. FAT has internal limits of 4 GB due to the fact that it uses 16-bit fields to store file sizes, 2^16 is 65,536 with a cluster size of 64 KB gives us the 4 GB. HPFS uses 32-bit fields and can therefore handle greater sized disks, but the largest single file size is 4 GB.

Video Domain Products - Video ShieldThe total space needed on the hard drive is a function of number of frames, number of events, video resolution(QCIF,CIF or FULL), and number of cameras involved. If I set for camera number one 100 Frames in CIF with interval of 1 sec and total number of events will be 100 then the calculation will be: 100x20x100=200,000KB= 200MB of space only for camera number one.

Related QuestionsHow do I know what the capacity of my iPod's hard drive is?
iPod Accessories FAQsMost hard disk producers compute disk mass this method: 1 MB = 1 million bytes. A 5 GB hard disk, as a result, is one that grips 5 billion bytes. Computers, as well as the Macintosh and iPod, gauge disk mass this method: 1 MB = 1,048,576 bytes. The disparity in these two computations is what causes the disk to come into view as 4.6 GB or 9.2 GB on a computer, but in fact be a 5-billion byte or 10-billion byte hard disk. For larger iPods multiply 4.6 by the real augment in mass e.g.

Related QuestionsWhy do you use RAID 1 instead of RAID 5?
Xssist™ Group Pte. Ltd. (Singapore) Frequently Asked Q...RAID 1 has better performance compared to RAID 5, in particular, the write performance is much better. As web and email servers does a lot of writes, to log files, email spools etc, RAID 5 is not suitable for the server. In terms of redundancy, RAID 5 has 1 parity drive in an array (of possibly 7 drives). With a failure of 1 drive, the array performance is badly degraded. This may lead to much higher IO waits, and the server will be unresponsive.
Related QuestionsHow do I avoid hard drive crash and maintain the portable / external hard drives?
ATMT Hardware |Hard drives are delicate machines, they are prone to vibration and shock especially when they are powered because they are spinning at very high speed (7200 RPM), vibration and shock can cause the reading head dip into the magnetic surface, which may damage the reading head as well as the magnetic surface (bad sectors). The golden rule: Do NOT move the portable external hard drives once they are powered; and move them only if the power is off.
Related QuestionsI have no need for RAID at this time. Can the RocketRAID 404 support single drive configurations?
HighPoint-Support-FAQYes - RAID is optional, not required. The card is capable of supporting RAID and non-RAID drive configurations. Aside from a physical hard disk problem, the most common cause of array loss are loose power or IDE cables. A failing or under-powered power supply can also lead to this problem. If the drives do not power on and "spin" up correctly during bootup, the RAID controller may not detect one or more of the drives - this may result in a broken array.
Related QuestionsWhy does my hard drive report less capacity than indicated on the drive's label?
ATMT Hardware |Hard drive manufacturers market drives in terms of decimal (base 10) capacity. In decimal notation, one megabyte (MB) is equal to 1,000,000 bytes, and one Gigabyte (GB) is equal to 1,000,000,000 bytes. Programs such as FDISK, system BIOS, and Windows use the binary (base 2) numbering system. In the binary numbering system, one megabyte is equal to 1,048,576 bytes, and one gigabyte is equal to 1,073,741,824 bytes. Simply put, decimal and binary translates to the same amount of storage capacity.
