HP Smart Array H240ar

RAID stands for Redundant Array of Independent Disks
If you need to achieve high reliability and efficiency in data storage and protection, you should buy RAID Controller HP Smart Array H240ar 12Gb/s cards and enhanced performance of your HDDs and SSDs. With used RAID Controller HP Smart Array H240ar cards bought from Ref Group Indonesia will protect your data from malware providing security with this back up option. You get access to all the options based on transfer rates, RAID levels, cache, form factors, etc. We can offer quite a wide choice of RAID cards from multiple brands at reasonable prices so that you could handle your business requirements.
RAID cards improve the storage and drive performance by keeping data on diverse disks, allowing overlapping of I/O (input/output) operations in a balanced manner, thus improving their performance.
There were only 6 RAID Levels defined officially but as time advances more level types has been added. Thus, here we will be going to discuss standard RAID levels only.
1. RAID 0
This type of RAID uses data striping. Data processing speed is increased because the available data is evenly distributed across multiple disks. This layer has no redundancy or fault tolerance as only striping is implemented without mirroring and parity.
2. RAID 1
The RAID 1 level implements data mirroring only, without striping and parity. Data is typically duplicated to another disk or disks. This layer provides redundancy, but not performance or fault tolerance.
3. RAID 2
Here the data is striped into bits (not in block ) and written on multiple drives. Along with striping, the parity bits are also used for forwarding Error Correction generally called FEC.
4. RAID 3
it uses a dedicated disk for parity. The parity bytes are determined for each row of data. The read speed is quite good and it has resistance to damage to one disk.
This type is preferred where a very small number of users want to access huge data, otherwise, it is not preferred at all.
5. RAID 4
This type is also like RAID 3 but the difference is that data is striped into blocks instead of bytes with a dedicated parity disk. As it has parity bits therefore in case of any loss, we could recover the data by using appropriate parity methods. It is also rarely used for practical implementation.
6. RAID 5
This type of RAID is most commonly preferred for file and application servers. This RAID type can withstand a single drive failure condition
5. RAID 6
This type is very similar to RAID 5 but the slight difference is in storing parity bits, otherwise, all the architecture is the same. The one parity bit is written two times on two separate drives instead of a single drive. Thus, it can provide an additional level of redundancy than RAID 5.
If you’re a professional or hobbyist who works with a lot of large files, like HD video, music, or other design projects, then the speed and reliability of RAID is perfect for you.
