The Vess A2230 12TB 6-Bay NVR from Promise Technology is built to offer high levels of performance for IP video surveillance and is well-suited for small deployments such as retail stores, clinics, classrooms and gas stations. It supports up to 35 IP cameras, is powered by a 2.0 GHz Intel Celeron J1900 Quad-Core processor and 8GB of DDR3 RAM and has a capacity of 12TB that is split over six 2TB SATA 3.5" hard drives, each of which utilizes one of the NVR's six drive bays. A 64GB mSATA SSD is built-in and hosts the operating system and there are also two Gigabit Ethernet ports, four USB 3.0 ports, two USB 2.0 ports, HDMI and VGA video outputs, three RS-232 serial ports and support for RAID 0, 1, 1E, 3, 5, 6, 10 (0+1), 30 and 50. For those who wish to increase the storage capacity of this NVR, expansion is possible through iSCSI and multiple JBOD expansion enclosures. The supported operating systems are 64-bit editions of Windows Embedded Standard 7 Runtime (WS7P) and Windows 10 and this NVR is powered by an internal 250W power supply that runs using 100~240 VAC at 50-60 Hz.

Vess NVR appliances reduce support and equipment costs because there is no separate RAID storage unit to manage, eliminating the need for a server, controller cards, external cables and a separate storage enclosure. Additionally, Vess NVR appliances reduce interoperability conflicts caused when integrating different hardware.

Vess NVR appliances are compatible with a range of IP cameras and VMS from vendors including Aimetis, Axxonsoft, CamIQ, CSVi, Digifort, Genetec, OnSSI, SeeTec, Sony and Milestone.

An SDK library is provided for VMS UI and management integration. Plus, Vess supports the Milestone VMS plug-in enabling it to be managed via the XProtect interface. Additionally, you can easily expand via iSCSI by adding Promise external storage.

A collection of unique features designed to provide a high level of service and overcome performance bottlenecks to allow Vess NVRs to handle a higher number of IP cameras.

Predictive Playback - utilizes idle recording times to monitor read patterns to predict where the next playback will be needed so the hard disk drives are not competing with the workload of the system.

Remote Active Service - proactively detects when the PSU, controllers, or HDDs are going into critical condition and automatically notifies Promise support so the customer can be contacted, spare parts can be sent out, or the unit can be powered up after an outage. All of these are vitally important in environments that cannot risk downtime.

Sequential Pattern Recording - eliminates heavy workloads caused by random write patterns by monitoring recording patterns, collecting data in the cache buffer and only writing data to the drive once a full stripe is ready. This creates a sequential recording pattern which offers smooth performance.

With just a few clicks of the Promise online planning tool, you can get the whole picture of what you need for your project, including the NVR and storage requirements, how to configure the servers and storage and see a topology of the interconnecting systems with the most popular and recommended settings.

Q: 10. What is the read/write speed of this model running at RAID-0? I want to buy a working RAID running at RAID-0 and a backup RAID running at RAID-6.

A: Preconfigured in Raid 5 (w/Blackmagic speed test) I got 828 write and 834 read. Once in Raid 10 (and walked through by tech support leaving all settings, sector sizes etc. in default) the test revealed 589 write and 629 read. I read in one of the reviews here that someone got 1,200 overall in Raid 5! I've got the latest Mac Pro w/processor 3.5 GHz 6-Core Intel Xeon E5, Memory 64 GB 1866 MHz DDR3 ECC, Thunderbolt 2... Don't know how they got that speed... Also, sorry I didn't answer your question about Raid 0 or Raid 6 speed. I saw people chiming in otherwise, and noticed at the moment this is the only speed related post here.
