Some fun facts:
1) SATA has been around for 19 years, while the lifespan of PATA was about 22 years (first drives started shipping in 1986 and by 2008 SATA took over about 99% of the market).
2) The original speed of PATA was 8,3MB/s and was bumped up to 33, 66, 100 and 133MB/s during its lifetime. That's a 16x increase. SATA's transfer speed increase so far is only 4x. (theoretically, if we consider the latest SAS-4 standard, we could stretch it to 16x, as it uses the same cable, but otherwise no SATA drives will benefit from such a fast SAS controller, and SAS drives won't be recognized by a SATA controller)

Let’s get the history correct here: SATA replaced ATA-5/6, it was only called parallel ATA posthumously. Even the term ATA, or AT attached storage, wasn’t used much, as everyone just called them IDE drives. PATA was never a standard: the 40 pin ATA cable, and the various PIO and UDMA modes were standards that rode over the basic ATA interface. An interface which started life as nothing more than an arbitrated bridge interface to the 16 bit IBM PC AT ISA bus (thus the name AT-attachment interface), as the core drive controller was located on the drives logic board (thus the name IDE, for integrated drive electronics).

Been awhile since a video hit 100% for me. I think SATA is one of those standards that has earned a permanent place in computing. It links legacy with constant future upgrades. My main laptop came with one 500gb m. 2 nvme stick, one empty m. 2 slot AND a 2.5 SATA bay😁. I slapped another 500gb nvme stick and a 1tb 2.5 in that sucker. I now can store everything from three previous household computer onto one laptop, keeping everything nice and separated 😌. Sometimes, it's just the simple things...

The section on PCIe lanes misses an important detail. On a lot of consumer CPUs there is 16x for the GPU, 4x for the first NVMe slot, and then any other NVMe slots are taken off the chipset. Since the chipset handles SATA and the extra lanes for the extra NVMe drives, the bandwidth there is limited to either the interconnect speed (SATA or NVMe), or the chipset to CPU link. However, generally unless you are connecting NVMe via PCIe riser cards, adding more NVMe directly to your motherboard generally doesn't interfere with your GPU speeds. Of course exceptions apply, and check the manual, but in most of the time you don't need to worry about filling up your motherboard's NVMe slots.

PATA died to SATA. Not anything else. SATA is much easier to deal with in many ways. The mechanical drives are the same. Only difference is the controller and the cables. PATA cables were thick ribbon cables and a PATA connection was limited to 2 drives, which needed jumpers set. In the space of a single PATA port on a MB, you get 6 SATA ports. There were usually 2 PATA ports, for a total of 4 drives. Moving to SATA allowed the space for ports to be cut in half on the MB, along with adding 2 more mechanical drives to the system, and then some MBs added 2 more SATA ports for a total of 8.
It's kind of like saying a MB got faded away because of newer MBs. It's true, but you still have a MB.
Many home systems don't need mechanical drives anymore. They've moved to large volume data storage, and for that they're still king. With 20TB drives now, 4 SATA ports give 80TB of storage. Somehow I don't see that being economical for a home user within the next 10 years if you move that to NVMe, that is 80TB of storage.
I don't see SATA ports going away anytime soon.
And, let's remember that the typical NVMe drive isn't really accessible. It sits between the GPU and CPU, or is under the GPU. This means you typically have to take off a CPU cooler to get to it, or remove the GPU, or both.

I was an early adopter of PCI-E SSD (it was an actual PCIE card called a RevoDrive by OCZ). The speeds were incredible for OS/primary drive use, even moreso than the SATA SSDs I had tried up to that point. I'm happy to see that boot drives are now commonly PCI-E powered via NVME and attached without using a proper PCIE slot (even if it uses lanes). But IMO, there is no reason to use more than one NVME. Additonal storeage shoud be via SATA, either SSD for fast secondary access or mechanical hard drives for large media files, backups, etc.

PATA went away not because of SSDs (it took them years to become cheap and common enough to justify any industry-wide changes) - it went away because every hard drive manufacturer moved to SATA, as it's a cheaper standard to implement, had better performance than PATA and was easier for users to deal with (fewer pins to bend and also no jumpers to set the drive role in the "chain"). It also had massive implications on the SMB server business, since you suddenly could manufacture cheaper servers using SATA instead of SCSI and fit a lot more disks per chassis with somewhat decent performance. This is exactly the same reason that not long after, SCSI went away and got replaced by SAS, also known as Serial Attached SCSI.
