About this deal

ATA streaming support enables recordings from up to 64 HD cameras for smooth, uninterrupted footage SSHDcombinethe latest NAND flash technology as used by SSD’swith a traditional hard drivefor a compact blend of capacity and speeds up to 5× faster than typical hard drives. SSHDdrives offer faster software and gameloading/installationtimes plus overall faster transfer speeds. We also test power consumption and temperature. Power consumption will vary with drive performance, RPM, and more, and it’s important to look at four different cases: maximum power draw, average power draw, idle power draw, and workload efficiency. Power usage can add up with multiple drives. Temperature is also an important metric for hard drives, as overheating is a common cause of failure, particularly during sustained workloads. SkyHawk Health Management actively helps protect your surveillance storage by focusing on prevention, intervention, and recovery options. Included is RAID RapidRebuild, which provides 3x faster volume rebuilds over traditional RAID rebuilds The majority of NAS‘drives’ come with a minimum3 yearwarranty, with some of the Pro models such as the Seagate IronWolf Procomingwith a2 yeardata recovery plan ( Seagate Rescue Data Recovery).

MTBF specifications are based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions: workload of 90TB/year and drive temperature of 40°C. Derating of MTBF will occur above these parameters, up to 65°C drive temperature. MTBF does not predict an individual drive’s reliability and does not constitute a warranty. With an MTBF of up to 1 million hours 3, WD Purple drives are engineered for mainstream surveillance DVRs and NVRs that operate 24/7. With tarnish-resistant components 7 and support in storage systems with more than eight drive bays 4, WD Purple drives deliver reliable operation even in harsh environments. Standard Hard Drives –have multiple uses but are designed for everyday storage and often used for computers and additional external memory. Available in 2.5” and 3.5” drives giving you the ability to upgrade your PC, laptopand even your games console. Finance is only available to permanent UK residents aged >18, subject to status, terms and conditions apply.

M hours MTBF, 3-year limited warranty represents an improved total cost of ownership (TCO) with reduced maintenance costs

The actual styles of cameras you use will have an impact on which Hard Drive you choose. For instance, if you have HD cameras with sound and audio, you will need more storage space. Best Hard Drive for CCTV DVR Reviewed

Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred ✕ (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations. Single stream at 3.2Mbps (1080p, H.265, 25 fps) for WD22PURZ, WD33PURZ, WD42PURZ, WD43PURZ, WD60PURZ, WD62PURZ, WD63PURZ, WD64PURZ, WD84PURZ and 2.6Mbps (720p, H.265, 25 fps) for WD10PURZ, WD20PURZ, WD30PURZ, WD40PURZ. Results may vary depending on camera resolution, file format, frames per second, software, system settings, video quality, and other factors. Unparalleled data protection with included 3-year Rescue Data Recovery Services plan, helping protect important video data with Seagate's in-house data recovery services

RV sensors built in allow drives to maintain performance in multi-bay systems, giving customers the flexibility to scale their systems when more storage is needed

What is an AV drive?

ImagePerfect firmware is designed to ensure seamless video footage capture in 24x7 surveillance workloads that record video from 64 HD cameras NAShard drives are specially designed for reliable, high volume, cool and quiet, 24/7 operation. They offer optimum compatibility and are perfect for home users, small offices or even larger companies looking to store high volumes of data in one location. An AV (Audio Visual) drive is basically a hard drive. But, unlike its standard HDD cousins, an AV is designed to be capable of streaming audio and video content 24 hours a day. They can also deliver a greater reliability than standard desktop drives. Here at Ebuyer.com you will find AV drives from both Seagate and Western Digital the leading brands in hard drive technology. The drives are available in both 2.5 inch and 3.5 inch form factors, with up to 6TB of storage. AV drives for surveillance

Seagate Firecuda‘drives’ are perfect for your SSHDapplications and as with desktop HDD’s, SSHDareavailable in 2.5” and 3.5” options. There may be a whole plethora of factors that affect your decision making process when it comes to choosing a Hard Drive for your DVR. To make this simpler for you, here are a few things to consider when deciding: Price Range The most common use for hard drives, though, is simple file transfers. Our DiskBench test estimates transfer performance with a real-world workload that is useful for calculating how long a transfer could take. Hard drives have consistent performance and will hit their maximum sustained speed at QD1 with large enough I/O, which is illustrated in our ATTO benchmark results. This is particularly useful for showing differences in technology and capacity as drives get bigger and faster. Your CCTV system will often have a few different moving components, however, connecting a DVR is one of the most important parts to installing your CCTV. Without a DVR you will not be recording anything, so your system will be rendered useless, aside from being a physical deterrent.
