The difference between Seagate HDD enterprise grade and surveillance grade is as follows:
1. Exos enterprise hard drive:
7200rpm, hard disk designed for disk array, 120W mean time between failures, specially added vibration compensation mechanism, effectively eliminate the resonance generated by multiple disks (resonance will cause considerable damage to the hard disk, it is recommended to use NS hard disk for RAID applications with more than 4 disks ); It has good stability and provides 7×24 continuous data reading and writing; it has the ability of data verification, and verifies the correctness and integrity of data by “reading after writing” data, and provides dynamic energy-saving technology, which is more suitable for application in disk array.
2. Special disk for surveillance monitoring:
7200rpm, designed for the harsh environment of DVR monitoring applications, the average time between failures is 100W hours, the low starting current is 2/3 of the AS disk (ordinary disk), and it can still work normally when the temperature is above 75 degrees; it supports 24 hours of continuous work, It is mainly used in hard disk video recorders, focusing more on low voltage and low power consumption. It is not as good as enterprise hard disks in terms of data read and write speed and data fault tolerance, and there is no data verification mechanism. Compared with enterprise-level hard disks, the failure rate of monitoring disks is relatively high, and project maintenance is troublesome.
Just look at the model. Seagate is divided into ordinary (home use) (DM), surveillance (VX), SSHD hybrid hard drive (DX) and enterprise (NM).
Seagate HDD is a product of Seagate Corporation and a representative work of Seagate. Seagate was the first company to bring to market technologies such as Perpendicular Recording, hardware-based full-disk encryption and hybrid hard drives that enable your digital life, whether from your home, handheld, car or office.
Continuously investing in the development of new technologies to increase performance, speed, and areal density (the ability to store more data in less space).
As digital content such as music, videos, photos and games become more and more part of people’s daily lives, static data storage is becoming obsolete. In today’s on-demand world, access, share and protect your digital content with dynamic storage solutions that give you the freedom to work, create and interact anytime, anywhere.
Seagate Hard Drive Model Nomenclature
Take Seagate 1.5TB ST31500341AS as an example
ST 3 1500 3 4 1 AS
- 1 2 3 4 5 6 7
- ST is naturally the abbreviation of Seagate, which means Seagate;
- 3 means a 3.5-inch desktop hard drive, and 9 means a 2.5-inch notebook hard drive;
- 1500 naturally has a capacity of 1500GB; needless to say;
- This bit refers to the cache number of the hard disk. In the 7200.11 hard disk, 3 means 32M, 6 means 16M, and 8 means 8M. However, in other series, the power of 2 is also used to indicate the cache size. For example, 3 means 2 Cubic 8M, 4 means 16M, 5 means 32M, 7200.12 series ST3500418AS is this way of representation, the cache is 16M;
- This number refers to the number of discs. There are 1 disc, 2 discs, 3 discs and 4 discs. Naturally, the fewer discs, the better the performance;
- The 1 here is the OEM version number, which may also correspond to factors such as the place of origin, and has no effect on the performance and other parameters of the hard disk;
- The last AS refers to the SATA interface, and SV/AV refers to the enterprise-level SATA and PATA hard disk, NS refers to the enterprise-level ES.2 hard disk, and CS refers to the Pipeline HD series audio-visual hard disk, low power consumption noise
When purchasing an enterprise-level hard disk, you can consult the customer service staff, and they will provide professional answers. Below are some sample model numbers for Seagate Enterprise Hard Drives.
