Who are we?

We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

We are one. We are legion. And we're trying really hard not to forget.

Remember Seagate’s Dual Actuator HDDs? They’re Back, in SATA Form (www.youtube.com)

What do you think of dual actuator hard drives? I never knew these even existed...

Here's a quick summary of the vid for those who want a TL;DW:

Dual actuator drives are a single drive with two actuator arms inside
These arms have their own platters, each with access to half of the drive's capacity
The SAS version shows up as two separate drives: one for each actuator
The SATA version shows up as a single drive, however can be partitioned at a specific LBA near the middle to use both actuators independently
Linux kernel updated to support these drives better when queuing commands
Capable of saturating a 5gbit SATA link

Personally, my concern is RAID setups, particularly in a SAS config. Will filesystems like ZFS and BTRFS know that two storage devices are the same physical drive... aside from that, and concern about more mechanical parts, this looks exciting especially for sequential speed throughput!

Timd to update your criteria, friend. Seagate hasn't been top of the failure stack for like 8 years now. The 3TB scandal era is long since passed. Now it's WD who has been shitting on quality control, sending out faulty SSD's that wipe user data, bait-and-switching HDD customers with a cheaper, much worse performing technology (SMR) WITHOUT TELLING THEM, them basically blowing corporate raspberries at everyone when people complain.

While i agree they were the best, HGST also hasn't even existed as a non-WD product for years....
