Hard Drive - WD Purple or?

I would go with the purple drive as it's specifically made for surveillance applications. Size depends on your storage requirements and the type of recording you will be doing. I.E continuous, event, scheduled etc. You can use a storage calculator to estimate how many days of retrieval you will have based on how you plan to record. I get about 7 days worth with 8 cameras recording continuous on a 3TB HD, just to give you an idea.

Technically you could use any drive and it'll still work, even an SSD would.
From what I have seen on numerous builds people just run drives specifically for the purpose, so either WD purple, or Seagate surveillance. They do cost a bit more than some other drives so it's up to you to decide. If you have drives laying around doing nothing you could use them if you want to save a bit of money.
Download the 'Tools' from Hikvision website, they have a storage calculator that will tell you the drive size needed for a time goal or how much footage you can store in a given drive size.

i also run reds as i couldn't get purple locally and needed drives fast. so far so good!
The Seagate Surveillance seem identical in price to the WD Purples. Maybe I will go with a 3TB Purple for now.
If I go with 2 drives on a 7616, can the second drive be configured as a backup for the first, or would it only be used when space was up on the first one?

I dropped on quite nicely.
An online store has an eBay store as well and had an email from a cash back website on Thursday that between 4-10pm there was 20% off everything on eBay with voucher code!!
Never seen an eBay code before
But I managed to pick up 2 new WD purple 3TB drives for £68 each!!!
£85 was the cheapest I'd seen them anywhere
I dont think you'd even get a desktop drive that price
Needless to say I was well chuffed
So today I was setting up a new DVR and was able to run some performance data using the Samsung SSD tool. I installed an SSD for the OS, and installed a 3tb WD purple. I then reformatted the original 500gb Toshiba drive and set it up for video storage also.
Running the numbers of course the SSD smoked everything else in a major way, but the purple drive was slower than the basic toshiba OEM drive in all but one important aspect. Write speed. You can tell these are tuned for write speeds in surveillance applications!
850 evo SSD - MB seq read speed 549, write 529, random read iops 96,000, write iops 86,000
Toshiba 500 - MB seq read speed 177, write 212, random read iops 688, write iops 312
3tb WD Purple - MB seq read speed 164, write 128, random read iops 518, write iops 749
The random writes are the important ones for recording video and it is double the performance there, while slower in applications the drive is not designed for. But really I want a monster SSD......

Guess I deserved that one! Just debating whether it's worth putting SD cards in. I like the thought that if something did happen and the theif took the NVR to eliminate footage that I had some other form of backup.

After which I assume it just overwrites?

If its a Chinese 2032F you are planning to use SD cards in just be aware there seems to be reports of issues with SD card recording.
Most are getting it initially setup, but once setup it's good.
Mine's been good for a month now.
