Make sure your motherboards will support the SSD. Check in your BIOS that your motherboard supports AHCI & your SATA interfaces support 6gb speed.
Yes, had one for years. Would never go back to spinning disk now. My main PC, which has a very high end SSD in it, boots up from button press to windows in under 3 seconds.
Make sure you keep a good copy of your drives contents to hand and backup regularly. I have two go belly up on me in the last few months, Western Digital Blue 500GB and a SanDisk 250GB. I have only ever had one spinning hard drive fail on me in 25 years.
If you have an m.2 slot on your Motherboard, I'd recommend using that. Make sure it's an NVME m.2 though, not SATA m.2
Yep, then use that. It won't make a huge difference to real life performance, but it's a lot more aesthetically pleasing and it will make a small difference to performance at least.
Nothing, they were in a case nicely separated from the mobo and any heat. I have got 10 year old hard drives in the same system so I can't really comment about my other SSD's longevity as I have only had them in for 2 1/2 years.
Funny, I was thinking of the same upgrade earlier in the week. Does anyone know if I'd be able to image a same sized traditional HD onto SSD to save the ball-ache of installing everything again?
Yes. Western Digital let you download Acronis Clone software if you have a WD drive. Or there's Macrium Reflect which I have also used.
