At the end of last year, the range of our devices was replenished with a new line, SkyHawk AI . These drives were created to work in video surveillance systems with support for artificial intelligence. Today we want to tell you in detail about its flagship model - Seagate ST16000VE000 c 16 TB of memory. Only one such specialized HDD can store a month of recordings from 15 surveillance cameras recording round-the-clock video in Full HD resolution at a speed of 25 frames per second.
Just a decade ago, a circuit of the same 15 CCTV cameras was the level of a large industrial enterprise or a protected area of a court, government or some other institution of special importance. Today, 15 cameras can belong to the microbusiness, which controls the warehouse and office, a fitness center or a small store. That is, this is no longer a luxury, but a means of video fixation, a utilitarian part of physical security. But there are no less problems: gigabytes of good quality video need to be recorded and stored somewhere, and this is also a key security element - otherwise why all these cameras?Appearance
In the appearance of hard drives it is difficult to come up with something fundamentally new. The form factor of the device is 3.5 ”, the case is made of aluminum, the top cover is flat, with a large marking sticker:
Bottom - a no less flat black surface, a quarter of which is the external board of the device. There are 4 mounting holes.
A weld seam runs around the entire perimeter, ensuring perfect filling tightness - it will not work to penetrate inside at home. And there’s no reason - except out of curiosity, out of boredom, or for getting expensive souvenirs (although visually there are the same “pancakes” as in other discs).
On each side there are three screw holes - the drive can be installed in any basket, even in a short one.
At the request of workers (from commentsto the previous review) we give more exact sizes:
On the front side there is a marking sticker with the serial number of the drive - so that you can easily find the desired drive in the NAS stack.Using
If you have only one camera hanging somewhere in the corridor, then even in this case you’ll have to store the recorded video somewhere (we don’t consider cloud services in this case - the storage of the video lies with the owners).To understand the scale, we turn to the table, which shows the approximate size of 1 hour of video recording with a fixed bitrate (with a very approximate comparison):It turns out that in the case of the mentioned camera, almost any drive will do, at least for 500 GB - there will be enough space for almost a week of continuous recording in good quality (and if you write using a motion sensor, then for longer). And if you use even the simplest SkyHawk drive (8 TB), it will close the need for video storage for months or years.But of course, when developing the SkyHawk series of disks, I meant a slightly different video surveillance, on a larger scale. Entrances, shops, manufactures, factories, government agencies - all these (and many others) scenarios that use tens or hundreds of high-definition cameras with various settings and technologies. In order for video from them to go continuously through professional devices, it is recorded on multi-disk arrays and reliably stored for a long time. All this is the native element for SkyHawk.Here, instead of an abstract plate, it is better to use our calculatorwhich has more input settings and more accurate output. Just specify the desired parameters (number of cameras / recording quality from them / number of hours of recording per day and days for storage / codec) and get the size of the occupied data: So, moving the sliders, we find out that the hero of today's review (16 TB SkyHawk AI) is enough for storing video from 15 cameras for a month, which will record around the clock in FullHD quality at a frequency of 25 frames per second (count, movie). // (!) (!) (!) - exclamation points for self-placement in the previous sentence.
15 cameras is, for example, an apartment building, in which 2 cameras hang on each of the 7 entrances - a completely protected perimeter with the ability to dive into the video archive for a month. SkyHawk AI is sharpened for round-the-clock operation in video surveillance systems, with a load of up to 550 TB per year - this is almost three times more than standard disks for video surveillance. And if there is a need for higher workloads, we recommend using enterprise-grade Seagate drives (for example, Exos, a review of which was on our blog).Of course, all these cameras will not be connected directly to the hard drive, but through a rather expensive NVR / XVR / *** - a device that will do the rest of the work: organize the archive and access to it, backup, process video streams (detect people, cars , face recognition, ...) etc. Not all devices, even from eminent brands, have support for drives of such a large volume, but there are already many to choose from: from the world leader Hikvision (for example, in the I-series, Super NVR and DeepInMind NVR lines) to the less well-known Dahua, TVT or Uniview . Up to 16 SkyHawk discs can be installed in HikVision devices - just imagine this setup and its capabilities.
Hikvision SuperNVR and Hikvision DeepMind NVR* * *Let's get back to our disk. The spindle speed is 7200 rpm - the golden mean, which provides the device with the necessary performance for working with video. As well as durability and low noise. You can see the noise values on the plate, but there are the values for the disk “on the table” - in fact, the disk will be hidden in the NAS / NVR or in the bowels of the system unit, where there will be no noise and vibration from it.High-speed measurements were made in the well-established utility HD Tune Pro version 5.70. All screenshots are clickable.Linear reading - from 120 to 266 MB / s with an average value of 209 MB / s, similar values when writing. Random access time is in the range of 11.6 - 13 ms for reading and tenths of milliseconds for writing - a good result, largely thanks to a separate cache.Read: Write: All Seagate SkyHawk AI series drives have a 256 MB cache - a solid size, but in this case it plays a special role. A new version of the ImagePerfect AI algorithm , which optimizes video streaming, guarantees the absence of missing frames in recordings, and minimizes data errors, is sewn into the disk firmware . The algorithm is based on the technology of multi-level caching (MTC, Multi-Tier Caching) and provides:
- Around the clock receiving video streams from 64 HD cameras.
- High speed streaming.
- No missing frames (due to error correction and data reconstruction algorithms).
- High image integrity.
- Support for the ATA-8 Streaming instruction set (for data transfer, priority is given to time rather than data integrity, which allows the host to request delivery of data for a certain time), optimized for processing large sequential arrays of data specific to video files.
You can learn more about the operation of the technology at this link , and visually look at this video:In the document at the link above, you can also find out more about the operation of AcuTrac technology, which provides stable performance and reliability even in conditions of strong vibration.Also on board is SkyHawk Health Management (SHM) - special software developed in conjunction with Hikvision (for systems with NVR OS 4.0) - SMART on steroids, which went beyond the industry standard. The technology monitors and analyzes data about the health and health of the drive, which can help prevent potential problems in time.Specifications Seagate SkyHawk AI
The SkyHawk AI lineup includes devices with volumes of 8, 10, 12, 14 and 16 TB. In addition to the volume, they differ only in weight, number of plates, power consumption and a slightly lower maximum constant data rate for the outer diameter (for younger models).→ Detailed comparison chart of the Seagate SkyHawk AI lineup→ White paper for Seagate SkyHawk AI 16 TBKey FeaturesCommon parameters: Seagate SkyHawk AI
