Best-In-Class Data Protection & Storage Efficiency
Delivering Best-In-Class Surveillance Recording to SMBs
RAID = various methods of distributing data across the hard drives to maximize storage reliability
or to enable the system to perform as quickly and efficiently as possible
RAID
Customize Your GVR3550 with one of three different RAID versions
to offer the data protection and storage efficiency that best suits
your surveillance needs

16. Recording Solutions
Best-In-Its-Class Data Protection & Storage Efficiency
Delivering Best-In-Class Surveillance Recording to SMBs
+ Maximizes Data Reliability (crash-proof)
- Lowers Total Storage Space
Mirrors the same data to 2 different hard drives
Mirroring the same data across multiple hard drives ensure storage
reliability/redundancy and offers the system 2 locations to access the same
data incase 1 hard drive may be in use at a future time or in case 1 HDD fails
+ Fastest Performance
- Corruption of 1 HDD Corrupts Full Video Sequence
Breaks a recording into chucks & distributes these
chunks of video across 2 different HDDs
System loads/writes chunks of a recording simultaneously rather than in
1 longer chunk
+ Maximizes Data Reliability & System Speed
- Lowers Total Storage Space
Mirrors data and distributes mirrored data in chunks
across different HDDs
Ensure data security because mirroring duplicates all your data. It's fast
because the data is striped across two or more disks, meaning chunks of
data can be read and written to different disks simultaneously.
