6TB Hard Drive For Surveillance? New Seagate Release
Apprerently Seagate has announced it's first 6 TB HDD.
The Enterprise Capacity drive has these features:
- 7,200rpm spin speed,
- 2, 3, 4, 5 and 6TB capacity points,
- 128MB cache,
- encryption option with Secure Instant Erase or SED FIPS 140-2 option,
- SAS 12Gbit/s and SATA 6Gbit/s interface options and
- a 25 per cent increase in areal density.
Seagate says its neat new drive can be used for:
- hyperscale applications,
- high-capacity RAID storage,
- mainstream enterprise external storage arrays (SAN, NAS, DAS),
- cloud data centres—replicated bulk data storage,
- enterprise backup and restore—D2D, virtual tape and
- Centralised surveillance.

Hitachi already relased 6Tb hard drives in 2013. They are hermetically sealed filled with Helium, allowing them to run at lower power, cooler, and increased capacity. In addition, they now can be liquid cooled - immersed in liquid. That could be very beneficial for disaster recovery in case of flood, fire supression system activation, spilled coke, etc...
Hopefully the competition for 6Tb drives will lower prices so they are practical.
See Ultrastar He6.

Of course they don't mention how "well" the drives work in those applications. You can tow a 25ft boat with a Ford Escape, doesn't mean it's going to do it very well or as well as a F250.
I wouldn't use such a large drive. Depending on what your storing this could be years of data.
Raid 5 rebuilds will now take 2 weeks ;)
The other new thing on these drives to watch for is called "advanced format sector" which is a 4K sector size instead of the historical 512 byte one.
The trick in this is whether or not 512 is native or emulated...and how the OS and hardware subsystems support the 4K part.
We are still evaluating the performance of these drives in our storage offerings.
