Seagate NAS drives including ST4000VN000 - now on HCL
There is only one thread on the entire forum about this drive. Has anyone installed these drives? There is a paucity of 4 Tb drives on the HCL. Edit: now whole series is on HCL Hopefully good a...
Seagate, Western Digital, and Toshiba are the three that are left. Though HGST appears to be operating somewhat independently from the rest of WDC.
Of course the SSD is the most interesting tech trend with 1 TB drives becoming available this year. And although the RNxxx line explicitly supports SSD drives, there are none on the compatibility list for the RN1xx, and only one SSD on the list for the others. And that one is only 250 GB.
With traditional drives, PMR is the current dominant recording technology - though Seagate apparently is shipping a variant (SMR) in some drives. Getting to higher storage densities will require shifting to something new, there is a summary of some of the possibilities here: http://www.forbes.com/sites/tomcoughlin ... sk-drives/ So there are some technology differences between drives, that that will probably increase over the next 5 years as some of these new approaches get commercialized.
But I agree that the recording technology, number of platters, etc. doesn't really matter to the NAS. The controller response to bad sectors, head parking times, amount of vibration, tolerance to vibration, and peak power use are the main things that do matter.
