https://www.overclock3d.net/news/storage/seagate_s_hamr_and_dual-actuator_mach_2_hdds_are_ready_for_prime_time/1 2019 is set to be a big year for Seagate, who plans to unleash two new technologies that will prove critical to the long-term success of HDD storage, both in terms of storage performance and when it comes to data volume. First up is Seagate's HAMR (Heat Assisted Magnetic Recording) technology, which will enable the company to release 16TB drives in the first half of this year. Beyond that, H2 of 2019 will see Seagate release their first dual-actuator (Mach.2) HDDs, which are designed to deliver up to 500MB/s sequential read speeds and up to 160 IOPS. Seagate is also planning to release HAMR HDDs with capacities of up to 24TB, a 50% improvement over this year's HDDs, delivering 3TB of capacity per platter to create 20TB drives over eight spinning disks. In 2024, Seagate plans to release 48TB HDDs, showcasing the future storage potential of HAMR-based HDDs, but this also highlights why the company's MACH.2 technology is also needed, as increased storage capacity without a boost to overall read/write performance will create issues of mechanical storage drives moving forward. What's the point in having a huge HDD if the data inside becomes further confined by read/write limitations. So there is still life left in mechanical hard drives in my personal opinion at least for the next few years.

This is impressive news, but I wonder about reliability and longevity.

hard disks have boosted the cache a lot and it has made a spectacular difference over older disks
my recently acquired 4TB disk can keep up with SATA SSD drives

Your current 4TB HDD can keep up with a SSD in what way?

I copied a bunch of games from an SSD recently to the 4TB disk and I was surprised at how fast it copied them
I was seeing Windows show 500 MB/s at times which is very eye opening
It seems that the large cache can leverage track writes very quickly, even small files did not slow the copy process much

If I can get a 16TB drive I would probably pick up one or two just for data storage. I have a pretty large collection of photos and while it would be overkill for size I really don't need a SSD for them.

right now now 14TB are as big as NewEgg has available
I backup photos to BD and store them in binders in case I want them for some reason

Run a Crystal Disk Mark test on your drives and post the results.

Nothing is stooping you from posting pictures of the results.

You can simply post the Crystal Disk Mark test result pictures, no website review link needed. quote removed by Cool GTX

Stop using binders and store them on spindles. I've lost hundreds of BD's in the last decade because the markings from the binders adhered themselves to the disc making them unreadable. And I literally mean hundreds, if not close to a thousand. Discs that have been stored on spindles are fine. I've had a BD-R since they have come out, so I speak from real world experience. I also used to be a mod at cdfreaks.com back in the day.
