Hard drive sizes keep increasing (up to 18TB announced recently) but what hard drive sizes do integrators most typically use?

~200 integrators responded:

What hard drive size do you most commonly use? Why that size and not larger or smaller hard drives?

In this report, we share detailed findings and key themes related to the most common specific hard drive sizes integrators use.

This is the successor to Video Surveillance Hard Drive Size Statistics 2018 and Video Surveillance Hard Drive Size Statistics 2016.

Some NVRs do not like drives larger than a specific size, often 8Tb due to the heat larger drives give off.

I believe a 20Tb drive is being announced at CES and will be available shortly.

This lines up with what I'm seeing. We don't order anything under 4TB for typical storage any more and we are testing 18/20TB HDD's for certification now.

Isn't there a trade-off with using larger drive sizes in RAID configurations? I believe I was told that the RAID recovery process time is greatly increased with very large hard drives.

Is NVR performance reduced, even slightly, during the RAID recovery process?

I know this is a bit off-topic, but can someone tell me about SSDs in Surveillance camera market? I understand that SSDs are a minor recording media. When/How do you use SSDs in the surveillance market?What are the biggest barriers? Price?

We do not use SSDs for video storage. If the directory and/or archiver are on separate servers we will use SSD in RAID 1 to mirror the OS and VMS thus providing redundancy within the server. There is a small RAID in the archiver usually 2 - 4 spinning drives to store video before is it moved to the storage appliances.

Not recommended. SSDs read and write very fast but have a finite number of write cycles as the cells degrade every time they are written to. Once an SSD fails, its data is pretty much unrecoverable. Cost per TB is also typically not economical.

No one ever complains about having too much bandwidth, too many pixels, too much storage or too much room in a conduit.

On the flip side, increasingly people will not pay much for more. For example, for most people are perfectly happy with home bandwidth of say 30/10 and will not pay much, if any, of a premium for 100 / 20, etc.

Years ago that was different when one was dealing with dial-up, ISD, low speed DSL, etc.

Well I recall a contractor decided not to break a 2" conduit and insert a junction box at the bottom of a riser. Instead they drilled a hole into a 90° elbow and fished the cable through the hole. Fortunately there was enough room in the conduit that other cables were not damaged by the drill bit. Unfortunately for the contractor, I noticed this and they had to pull and re-fish all cables, replace the 90 and insert a JB for the rogue cable.

keep your eyes open!

We have switched over to Coldstore which does not require a RAID rated or WD RED drives. This has resulted in significant savings, in 5 yrs running 6TB drives we have experienced 1 drive failure (another drive failed DOA out of the box). Total 182 drives in the array.

The Coldstore system now supports 16TB drives! using 14 of the 15 bays in a Coldstore Pro 3U (sequential overlapping write) we can get 224TB storage in 3U @ 60 watts power consumption.

Contrary to Hyper-converged rumours, we have not experienced drive failures due to spin up/down for writing and have not experienced lags in video retrieval requests.

I'm curious to know what brands and models people prefer for surveillance drives. I know there are surveillance-specific drives but are they really better for the task?

My preferred brand for decades has been Western Digital. I've had issues with Seagates and bad sectors.
