Compatibility of Seagate IronWolfPro 10TB HDD with SATA3 PC and Seeking Fast 1-2TB Disk Alternatives

I found something like this:

Seagate IronWolfPro server disk, 3.5``, 10TB, SATA / 600, 7200RPM, 256MB cache - ST10000NE0004.

In HDTune it has max. 247.5 MB / s / min. 210.7 MB / s
The average HDT is 240.7 MB / s
ATTO says that reading 252.645 MB / s and writing 246.271 MB / s

Will this drive work with a regular PC that has sata3?

Question 2: I am looking for a 1> 2TB disk which is extremely fast. I do not know what to choose. Searching I came across IronWolf but they don't have smaller ones and this one stands at PLN 1800.

I have ssd. Unfortunately small. (Sandisk Plus, 120GB). Bought 2 months ago. I also have 750GB 2.5 5400 8M from a laptop (sata2) and some old 3.5 "250GB 7200 8M which I removed from the old decoder . The first one is 4 years old and unfortunately he is too muddy. The second one from the decoder is better but it is still too small.
The space used on all drives is: 345GB, 205GB, 110GB of which the last 110GB is just ssd. 345 + 205 + 110 = 660GB. The cheapest SSD 500GB is about 650 PLN. Unfortunately, I will not be able to afford this year. The second thing is that ssd quickly loses its properties.
When brought from the store read / write seq. it was much bigger now:


On the 250GB disk I have Windows 10 Pro because after all it has faster reading like this 2.5 from a laptop:



and this drops to even 50MB / s on the last partition:


I saw that on many server disks the reading flies at the level of 200-250MB / s and if on the current 70MB / s this Windows is working, then 200-250MB / s will work several times better.
Another thing is that it stores a mass of data. For the price of cheap ssd) 500GB) PLN 650 I really have two specific hdd disks.
I just don't know what the difference is between a server and a regular disk.

The last thing is that, for example, many Microsoft programs will not be installed on other drives, even if you want it so badly. An example is Visual Studio Community 2017. The selected partition, e.g. D: \ VSC \ will install less than 4GB with ... well ... with 65GB! The whole package for C ++ / C / JAVA / NET and several others is 105GB, selected ones are 65GB and less will not be. Too early I thought about replacing the ssd (I had 60GB). If I knew, I would take a 250GB minimum.
As of today, I won't allow myself such expensive news. In two months I replaced cpu + mb + ram + monitor + vga + power supply and a lot of others. The sum total went almost PLN 3,000. Now I am looking for something quite normal, i.e. a disc min. 500GB - max. 1TB.
I also noticed that the smaller the older. Older and worse and probably will end up with some 2/3TB but I don't need one for the bank.

You say some Seagates have a reading of over 200MB / s. That much would be enough.

I got a computer from the company so out of date.
