Reddit mentions of Seagate 1000GB Serial ATA IIINew Retail, ST1000LM048New Retail)

As long as it is a SATA 2.5 inch HDD you should be fine. You could upgrade to an SSD if you really wanted to. I found this drive which is cheaper and faster than all of the drives you have listed.

An SSD would improve battery life, speed and longevity of you laptop. It will make it feel like brand new. I would recommend a Samsung 850 EVO either 250 GB or 500 GB capacity.

I personally upgraded my Mid 2012 MacBook to an SSD ant the boot time went down to seconds. If you prefer more storage and cheaper options then go for the HDD.

Wrong. Some 2.5" drives are 11mm (or more) thick and will not fit in the PS4. Like this one for instance : https://www.amazon.co.uk/Seagate-BarraCuda-Internal-Drive-Factor/dp/B01LXCE9W9

That will not fit internally to the PS4, even though its a 2.5" drive. I'd guess that it needs extra platters to give the extra space, so had to be thicker.

Thus one would fit fine as its only 7mm thick https://www.amazon.co.uk/Seagate-BarraCuda-Internal-Drive-Factor/dp/B01LY3Q201

I'd recommend Seagate Barracuda. Give me a moment to find the link.

Quoto /u/iamAVRG . Magari non serve essere scienziati per una build, però

• ho cercato l'hdd che consigli tu e su Amazon (5400 rpm <- lol, 8 MB cache <- lol, 340 GB <- lol, SATA2 <- lol) lo trovo a quasi €50 e, tra le robe che consiglia Amazon, vedo questo (5400 rpm <- lol, 128 MB cache, 1 TB, SATA3) a qualche € in meno. E cercando si trovano probabilmente cose migliori allo stesso prezzo
  
  
• su trovaprezzi il prezzo minimo per una 1070 è sui €380, l'utente ha detto che non vuole i dettagli ad ultra e non deve fare chissà che robe pesanti, quindi una 1050 (da <€150) basta e avanza... oddio, magari non avanza, però vedo che a me basta una HD7770 del '15-'18 per giocare a TW3, dettagli medio-bassi a 20-25fps, e su GPUUB vedo che la 1050 è un bel passo avanti, quindi direi che probabilmente ci giochi TW3 (su Toms dicono che stai sui 60fps con la 1050)
  
  
• ha detto che ha l'SSD quindi consigliare di prendere un SSD è un po' bizzarro (ma forse stavi solo confermando all'OP che un SSD è buona cosa)
  
  
• PSU e case con PSU integrato (tbh non sapevo neanche vendessero case con psu integrato, ma tant'è)

Here is the link to how to install it again
