How many different raid levels are there?
There were originally five different RAID levels. However, you can use a number of hard drives to create more raid levels, although this may affect performance.
What companies offer RAID 0 recovery services?
Data recovery services offers this service. They have offices in many different cities. RAID services is a hardware based data recovery solution when hard drives and motherboards go haywire.
How long do hard drives last?
Hard drives last for many years
What is raid support?
RAID stands for "Redundant Array of Inexpensive/Independent Disks". RAID can increase performance and/or data redundancy and/or capacity. There are many different RAID types, the most common being RAID 0 (stripe), RAID 1 (mirror) and RAID 5 (stripe with parity).RAID works by combining two or more hard disks.In a RAID 0 (stripe) array, data is split equally between the number of disks in the array. For example, when a 2 MB file is written to a RAID 0 array with two hard drives, the file is split in to two parts and 1 MB of data is written to each hard drive. This increases capacity and performance, but sharply decreases redundancy since only one of the drives needs to fail for all information to be lost.In a RAID 1 (mirror) array, a complete copy is written to each hard drive in the array. Capacity and performance stay the same, but redundancy is increased. As long as one drive works, you will not lose data.In a RAID 5 (stripe with parity) array, you need at least three hard drives. Files are split up to all but one of the drives (similar to RAID 0) and a parity bit is written to the last drive. This increases performance, capacity and redundancy. Performance is not as good as RAID 0, but still better than RAID 1. Redundancy is not as good as RAID 1, but is still quite reliable. Capacity is the sum of all but one of the drives.There are other RAID levels, but they are not as common.RAID support simply means that whatever device is being described supports RAID. Nearly anything supports RAID. The only computer component that "RAID support" would be relevant to would be a computer motherboard or an IDE or SATA controller.
What kind of software is available for RAID recovery?
There are multiple software’s available for recovering data from RAID but as RAID is a complex structure and recovering data from Corrupted RAID is a complex and time-consuming task so you should rely on a software tested and recommended by Data Recovery Specialists. One of such software is Stellar Data Recovery Technician that recovers lost or inaccessible data from RAID 0, RAID 5 and RAID 6 drives. This software is a complete solution with advanced features to recover files, photos, videos, emails etc. from Windows-based hard drives, external media and RAID array. You can try this tool for free and the tool can also be used in scenarios if probable RAID construction fails.

RAID stands for "Redundant Array of Inexpensive/Independent Disks". RAID works by combining two or more hard drives. It can increase performance and/or data redundancy and/or capacity. There are many different RAID types, the most common being RAID 0 (stripe), RAID 1 (mirror) and RAID 5 (stripe with parity).In a RAID 0 (stripe) array, data is split equally between the number of disks in the array. For example, when a 2 MB file is written to a RAID 0 array with two hard drives, the file is split in to two parts and 1 MB of data is written to each hard drive. This increases capacity and performance, but sharply decreases redundancy since only one of the drives needs to fail for all information to be lost.Performance = Drive Speed * Number of DrivesCapacity = Drive Size * Number of DrivesRedundancy allows for no drives to fail.In a RAID 1 (mirror) array, a complete copy is written to each hard drive in the array. Capacity and performance stay the same, but redundancy is increased. As long as one drive works, you will not lose data.Performance = Drive SpeedCapacity = Drive SizeRedundancy allows for all but one drive to fail.In a RAID 5 (stripe with parity) array, you need at least three hard drives. Files are split up to all but one of the drives (similar to RAID 0) and a parity bit is written to the last drive. This increases performance, capacity and redundancy. Performance is not as good as RAID 0, but still better than RAID 1. Redundancy is not as good as RAID 1, but is still quite reliable.Performance = Drive Speed * (Number of Drives - 1) (Theoretical)Capacity = Drive Size * (Number of Drives - 1)Redundancy allows for one drive to fail.There are other RAID levels, but they are not as common.The main benefit of using a RAID array is data redundancy and/or performance.Non-commercial (home) users and enthusiasts wanting a very large increase in performance (theoretically multiples of the number of drives used) usually go for RAID 0 since they often are not too worried about drive failure and they enjoy the larger drive capacities that it provides.Small businesses who only need cheap redundancy usually go for RAID 1. If one drive fails, the drive can be replaced and the mirror array restored.Larger businesses or those needing file/database performance go for RAID 5. They can afford the price of an extra drive and a more expensive RAID controller. RAID 5 provides high performance with large capacities while still maintaining data redundancy and is the most desirable in a business or enterprise environment.There are some other options for RAID such as RAID 10 or RAID 01.RAID 10 features two separate RAID 0 arrays which are then mirrored in a RAID 1 array.RAID 01 is the opposite, with two separate RAID 1 arrays which are then striped with a RAID 0 array.There are other non-standard RAID levels, but most are rather uncommon.Alternatively, there is also drive spanning (aka JBOD), but this provides no extra redundancy or performance. Drives are "glued", if you will, end to end.The benefits of each RAID level vary. The type of RAID used depend on the job it must fulfill.
A computer store sold a total of 300 items last monthThe store sold six times as many hard drives as they did CD-ROM drivesand half as many floppy drives as hard drivesBased on this informationhow?
240 hard drives, 20 floppy drives and 40 CD-ROM drives.
What is RAID discs?
There are no RAID "DISCS". RAID (Redundent Array of Independent Disks) is a method of storing data on separate hard drives in order to either increase data transfer speed or to allow for recovery of data in case of a hard drive failure. There are many different types of RAID configuration which I'm not going to go into here.Answer--Redundant Array of Independent Discs Lets start with the basics. R.A.I.D. Redundant Array of Independent Discs. In the old days it also used to mean Redundant Array of Inexpensive Discs. A RAID system is a collection of hard drives joined together using a level definition (see levels below). There are many uses for it. First it can be used to stripe drives together to give more overall access speed (level 0). Second it can be used mirror drives (level 1). Third it can be used to increase uptime of your overall storage by striping drives together and then keeping parity data, if a drive should fail the system keeps operating (level 5). Most people use level 5 for the uptime purposes and its ability to join together 16 drives, giving a large storage block. Read about the levels below and see which one suits you best.
Where can I find the best deal for computer hard drive?
Bestbuy.com has many great deals on many of the leading hard drives on the market today. Additionally, I'd suggest looking at solid slate drives (SSD) over the traditional hard drives.
How did you synchronize 2 hard drives?
It is possbile under a program called RAID. Do some research on it, cause there is RAID 0, RAID 1, etc. But basically your hard drive is set up to write data to both hard drives at the same time. Or, you could make an exact copy of your hard drive using the program from Ghost, and copy it on the second hard drive.

In my opinion, the best thing to do for a print server, if anything at all, is add more system RAM. This will help the server spool documents if you have many clients printing large files and help prevent excessive paging.If you are having a specific problem with your print server, please explain it in the discussion page and we may be able to help you further.
