I want to get a SSD 500 gb for Sony Vaio-71614M, I am willing to spend between 20 and 50 euros. If possible a SSD with a SLC memory.
Do you guys have any advice or product recomendation?
I would be careful with the Intel SSD's, don't be fooled by cheaper prices, we've had many Intel SSD's fail at work or that claim to have a high TBW (Terabytes written over the life of the drive) but have a shorter lifespan. Sounds like you want a cheap SSD option for your laptop, I've loved my Silicon Power SSD that I bought off of Amazon: https://www.amazon.com/Silicon-Power-Performance-Internal-SP512GBSS3A55S25/dp/B07997QV4Z
