Best SSD/HDD for my usage!!

Hi, i'm interesting in upgrading my Storage from my system.

Currently, i have 2 HDD.

1) Samsung HD502I , 500GB, golden one, 7 years old (and i'm sure its more older!) . Here i have my SO and games from Steam/Origin.
2) FUJITSU MJA2160BH G2, 160gb (almost 2 years old). here i have Ubuntu installed for the university, working fine at today (its from a dead netbook, but, its something!)

Well, like you can see, they're old, working at 5400RPM and with sata from old generation.

Now, my idea was buy a SSD (120-128gb) for ONLY SO (Installing W10), and a 1TB from HDD. (gaming, movies, series)

List of SSD (120gb) avaiable in my country -Argentina- (from cheaper to extensive).
Kingston V300
SanDisk Plus
adata SP550
Sandisk Z400
Corsair Force Lee
Intel 535
Samsung EVO 850.
Samsung PRO 850.
Notes: Samsung EVO almost cost the double of the KingstonV300, PRO cost 2.5x price of KingstonV300.

HDD:
Well, there is not a 'lot' of HDD here, all avaiable are WD (red, black, purple, blue), but i think the best HDD from my system will be a Blue or Black, no? Will they work at the same performance? (Mainly i want 7200 RPM i dont care the noise)
Also, there is a Seagate which cost a lot cheaper.

Mainly the SSD i want is for faster SO work, I see the best one for me is the adata SP550 (because it have almost have the same read speed as Samsung EVO) but, i want to hear some opinions here, and which is better for me!

Thanks you community!
 
I would not go for an Adata SSD drive.

I can tell you about the Kingston V300 drives though since I have used one as the OS drive and for a few other programs.

The maximum read and write speeds you get are 450 MBps
It will boot fully boot windows OS to the desktop in about 11 seconds.
And reduce load times for other programs.

I have been running mine for two years and have not had any sort of errors or breakdown of the SSD drive it`s self, and consider it very reliable.
The drive gets used every single day, and the performance has not decreased.

I have three Seagate 1 TB drives also in the system used for data storage.
Not one of them has failed on me or had any sort of error again with two years of use.
All 7200 rpm drives and compared to some drives they are pretty quiet at 7200 spin
Speeds anyway.
