I can't think of any reason to use SSDs for storage (as opposed to the OS). Speed isn't really an advantage, density is.

Same here. We used to upgrade the OS drive on our old pc based systems we built in house, but that is no longer the preferred route. Boot would be extremely fast which was ideal for minimizing downtime. For storage, I see no benefit.
I have considered it with the Samsung SM863 drives.
Let me explain the thought process:
- 5.6TB of SSD storage for 100 cameras over three or four days
- Every two days, the data would be moved to an archive server (hard disk based) without the main server breaking a sweat
- Ultra fast NVR and the SSDs would have a life expectancy of 7 years with H.264 compression
The reason we did not do it - cost. Each 960GB SSD is around $600-$700 and it was just easier to use mechanical drives for bulk storage. The SM863's have a 6,160TB lifetime write and are among the few SSDs that can handle a surveillance application long-term.
Ask this question again in 3-4 years and I am almost certain that SSDs will narrow the gap for $/GB and will be used for higher-end systems.

I recently "built" our own NVR that has 4 ports of POE on board plus a dual nic. with Ubuntu and running Spectrum. We use this for small systems 4-8 cameras and use an SSD in it. Typically these systems are in homes, and the clients want ultra fast/smooth playback and that's what you get with an SSD. When you scrub video on your iPhone or the Client remotely, it flys. We use 250GB SSD's for 4 camera installs and 480GB for 8 cameras and get about 3 weeks of storage using 4MP cameras and H.264+ recording 24/7, low res on no motion, high res on motion activation. Another reason we use SSD's is that a standard HDD won't fit lol.
On our servers for larger systems we use SSD for OS drive.
Except for mobile applications, no. Our OS drive is almost always SSD. I think this will flip in the next few years.
Write cycles on enterprise grade SSD drives are high enough now for video recording. The cost is high, so I wouldn't want to use it for long term archives.
I was going to use SSD for the realtime video storage on a busy Milestone Corporate server but after Milestones latest release added a feature to use RAM for that storage there's no longer a need.

I would stick with WD Purple drives or something similar to that; though I have started using SSD for the cache, I am sure it lowers the lifespan but it help minimize errors on the larger systems
Anybody tried out the new Intel Enterprise SSD drives for short term video storage?
Intel SSD P4600 3.2TB
SSD non-volatile state works better for certain jobs. They pay more, but in places like open warehouses and shops where it gets dusty and lots of air issues, its worth it. Especially if space is limited
