For me the answer for this is: use what you need. For example consider raid. On my desktop I have an mdadm raid level mirror. It is only a desktop used for some task at home (testing, coding...). Why buy a valid controller like areca or (as suggested on a discussion, maybe on reddit) an HBA to make a simple raid? I don't need an HBA or an high value controller on my i7-2600k. Then the consideration should be "if you need high disk I/O perfomances and a lot of space buy the right hardware."
For example there are a great number of small offices that need of little nas. There are cheap products that can perform well this operation but these are not valid hardware. I'm not a fan of this solution types but many technician install them because the committent says "oh please, drop the price". If for a small office, a technician must get a 1000/1500 $ for a server to serve as nas, he will not work. I have seen this type of product on lan with 120 hosts with a deadly performances.

For my personal use I would replace that Drive asap.
- There is no warranty for it anymore (time since buy)
- You can't buy it new anymore (discontinued)
- There are more reliable drives available.
I'd go for a Samsung Evo 850, that will give you five years of warranty.
But, it's your drive, you make the decissions.
- Yamaban.
Thank you for your suggestion.
What do you think about Corsair Neutron XTi 240 MLC?
Amazing. He suggested you definitely reliable drive (Samsung). Reliable in my boot too. You ask his opinion about yet another Corsair. One by Corsair failed on you already. So, you should have better knowledge about Corsair's SSD reliability, right?
Sorry to sound sour, it just amuses me how people keep buying things made by the same company whose products already failed on them. This is what creates the problem: keeps companies manufacturing bad hardware exist.

Sorry, but my 2 ssds corsair does not report error and works fine, with good performances and without realloc. These disks are not failed. Yes, they are failing but these are old driver and this is a desktop under raid. Consider that these drive are 5 years old, for me this is not bad ssd brand, there are best brand but corsair is not too bad.
Now, Yamaban had suggested samsung because this is the best choice. This does not exclude that there are other products (that can be less reliable and less performant at lower cost) that for my case are good enough. Corsair neutron has also 5 years of warrenty.

If you are AMD user and your old AMD cpu died, You think that AMD must burn due to a cpu failure? Great. I'm with you in the case where you buy a disk and after 3/6 months it fails (and this can happen also with very good brand) and this is not the case. Backblaze must burn all brand because many disks fails....
Now about bad hardware manufacturing companies it's another problem. These companies point to low cost consumer, due the fact that not anyone can get the best hardware due to money. An example? Corsair LE 480 GB (100$) vs Samsung SSD Serie 850 Pro 512GB (260$). 850 Pro is better, but more expensive, and Corsair LE has 3 year of warrenty. Maybe an user can spend his money for a vga or a better cpu. These bad companies permit some users to get hw for less money without a great expecation for cheapest use case and their ability to pay.
Yes, indeed, I'm with you on that. Market is driven by low budget (ignorant - not to offend, but to just qualify in insight into hardware) consumer. Which indeed leads to "fake raid" chips (aka "software" raid), and many other bad things. I sometimes have to deal with what students have ordered themselves. Hence excessive attitude. As they order before they hear from me: "pricegrabber is an enemy in choosing reliable hardware". Then all leads to downtime, someone has to spend time on repairing the darn thing. Whereas, if one pays mere 15% more and gets good hardware, future losses (including human time which is very expensive) can be avoided. Alas, SSD difference in hand is larger that 15%, hence probably nobody will dare to help with advice. If there is good advice that is. I for one did go with Samsung SSD...

Than if these cheap companies must not exist, the user must not use a new technology (at lower cost)? The IT gap.
Sorry, my (m.)2 cents.
