Why are you assuming that he needs to go and spend that extra cash on some PC component? This is not a new build thread and he is not asking suggestion for a few build as far as I can see. The Thread starter is only asking for opinion on two SSD's both of which are under 4.5k. One of those choices included an used Intel SSD from some enterprise. So, I can only assume that the price point is important to him. You are suggesting an option that is at a 20-25% higher price point. Nothing wrong in suggesting, but you are trying to portray it as the only option he has..
And btw, the crucial MX500 was available for 4.6k odd when I last checked.
Warranty wise, Corsair has the best after sales support in India. Both times I had to RMA by Corsair SSD's, I was given brand new replacements within 2 days.
I don't know where Samsung stands on that front for SSD's. Its one thing to have a 5 year warranty and a completely different thing for that after sales to be good which very few brands in India have. What is their after sales for SSD like and do they issue brand new replacements are refurbished units and what is the wait time?
I am myself currently running a Sandisk Extreme Pro 480GB bought from US and it does have global warranty, but never had reason to avail. I am planning to get a Samsung 970 Evo 500GB NVMe for my new build, but It will also likely be from US without warranty given the bad pricing in India.
You are just making far too many assumptions that don't necessarily hold true. There are a lot of casual users out there who don't necessarily game or into VM's and development tools,. but still have a 100 GB audio/video library and only a single drive keep everything. You are assuming that everybody can install a secondary hard disk for extra storage. What about people who are on a laptop? You forgot that people can install SSD's into laptops? It is not too uncommon for people to buy a cheap SSD and extra RAM to add a new lease of life into an aging laptop.
Disk Space is something that can always be made use of regardless of type of user. Throughput is not something that can always be used.
