Win Does HDDs necessarily transfer to 4Kn format for play H264/265+10bit ?
#1
I have several HDDs of "WD Ultrastar DC HC550 18TB 7200RPM"
As I know its default format is 512e, which is use for old operatopn system.
Since most videos are popular coded by H264(x265+HEVC)+10bit, Kodi also support it for a long time.
If I transfer my WD HC550 from 512e to 4Kn, will it be more efficiency for H265+10bit when Kodi play it? 
Such as smoothly play H265+10bit with madVR?

My hardware:
Intel i7 10th (10700k)
Kingstone DDR4 16GB 
ROG Maximus XIII Hero(Z590 chipset)
Asus Geforce RTX 3060Ti 8GOC(Support HDMI 2.1)
Intel SSD (Win10 ltsc) *1set
WD HC550 (Video files of H265+10bit) * 3sets 

Software
Win10 Ltsc
Kodi v20.2 (Nexus) with skin Aeon MQ9

TV: LG 75QNEDSQA 
AMP: DENON AVR-X1700H 
HDMI: FIBBR Pro2 2.0(21Gbps) x2

any halfway recent HDD should be fast enough to play any video file, independent of the sector size

hard drives only need to be as fast as the original optical disc which isn't very fast

or to get detailed

it only needs to read the file at (or just a little above for caching) the total file bitrate, the most bitrate i have seen in any movie so far is 90Mbps, add 1.5Mbps for the audio stream and you're still well below 100Mbps

an SATA interface is rated a 6Gbps (6000Mbps) and an average magnetic drive will read 640Mbps and an SSD at 1.6Gbps (1600Mbps)

by the time the hard drive is bottlenecking a video file the video decoding hardware (CPU/GPU) will just be incapable of playing it any way


(i took the disk speeds from this page https://tekie.com/blog/hardware/ssd-vs-h...eliability but i concur with their results)

I've not had a single piece of consumer-level media that has required speeds that a single SATA-connected HDD can't deliver.

Every time someone asks if a hard drive is 'fast enough for some sorta media file', it's telling that they have no idea how utterly slow an optical drive is compared to even the worst hard drive, but the optical disc is still fine.
