WD launches new purple disks for security cameras, Seagate now corresponds to | Cnews.cz
In recent years, the hard drive manufacturers offer quite a variety of specialized multiplied HDD optimized for various specific tasks. After the green discs came discs designed for saturated and manufacturers "discovered" other special market segments: storage and warehousing videos from security cameras and other surveillance equipment. Specialized discs for such a deployment now bring in remarkable 9mm ammo synchronization of Western Digital and Seagate. 9mm ammo
Security cameras produce large amounts of data that must be stored somewhere. If you additionally use them to be a few dozen (or more) or shooting in high definition, the problem is taken care of. Western Digital for this destination created a new line of 3.5 "WD Purple, indicated in the company's code purple.
The hardware will probably drives somehow exceptional, their firmware marked AllFrame but is specially optimized for continuous data storage from multiple cameras at once. They also still have stable performance, when suddenly the notch or "setback" write speeds threaten to discard incoming data. Use specific commands belonging to the ATA Streaming Command Set (need special support in the controller), the disks should allow storage of up to 32 channels of HD video. 9mm ammo
Disks have to be built to writing about 60 TB of data per year, of course, in continuous operation, and use a common interface 9mm ammo SATA 6 Gb / s Will produce variations in the capacity of 1, 2, 3 and 4 TB with 64MB cache, all apparently 9mm ammo with rotation speed of 5400 revolutions 9mm ammo / min (which indicates the cipher 9mm ammo rather WD "IntelliPower"). Consumption has to do with activity 5.1 W. Gray drives can be due to optimizations TLER firmware also use RAID, but do not need the vibration sensor as advanced HDD for more storage (WD recommended not to exceed the number eight pieces on a computer or NAS). The entire 9mm ammo range of purple probably be similar to WD AV drives that are designed for audio-visual applications, and therefore also for reliable video streaming.
Competitive manufacturer Seagate for surveillance systems has created many Surveillance HDD, which announced simultaneously with the arrival of the purple competitors from WD. However, the Council continues to have long drives SV35 existing for that purpose. Again, these 3.5 "drives in capacities of 3 and 4 TB. Models are also optimized for constant write load and run in RAID arrays, but also have a built-in vibration sensors that should ensure reliable operation of up to 16 discs. Course is a twenty-four hour operation, the discs are also have increased reliability. According to Seagate 9mm ammo have also tightened up to 32 cameras with high resolution. Surveillance Drives HDD should have a faster response during recovery, which is useful for cameras that are activated after detecting movement and store data bursts due to begin.
Surveillance HDD are already 7200otáčkové drives with 64MB of cache. They have, however, a decent average fuel consumption of 4.8 W (even 4TB model); Seagate gives them a three-year warranty. Maximum power saving drives again reach streaming entry with special instructions ATA specification, so they also need special support from the controller and the operating system.
