Yes ! are right. but not really if you belong to Pakistan / India / Bangladesh etc. So i try to describe the reason why System pulled SSD is much better then any new one. 
All new SSD's came here from china. however it is Samsung or Kingston or SanDisk. all are specially made with low quality for these countries due to low market prices. 
at the other side the system pulled SSD's are specially made for branded systems which shipped from UK / USA. and those SSD's passed many survival tests. and long live and gives you more better results on random sq test read write. after an years. even more better then a new one like Laxer, kingdian, Kingston, etc ..

I undesrstand your reasoning there, but you should pay attention to the part that said:

I agree!.. But not only that, I would also advise against buying second-hand SSD devices. SSD devices, unlike HDDs, degrade faster especially when not used carefully : it's generally advised to always keep sufficient free space on SSDs to keep the Write Amplification Factor (WAF) as low as possible.

SSDs not properly used during operations wears off quickly due to high WAF values. It's a side-effect of how SSD technology works... check  Do SSDs Degrade Over Time – Part 2 on how that works.

Thus buying highly reputable second-hand SSD device brand doesn't guarantee you a decently functioning SSD if it was used carelessly in its previous 1/2/3/.. years  of operations... You can, indeed, stumble upon a decent SSD that's still able to deliver a decent performance... BUT I expect it to be the exception rather than the rule...

Hence why I advised against buying second-hand SSD devices where ever you're located..

I have a TC-SUNBOW 480 GB SSD model: X3-480GB. I rarely use it though but it didn't fail, yet. I even used it once in a PS4. However the speeds of course are more or less like SATA II. Still faster than HDDs in some / most cases though. It simply lacks the trust to be put into real productional use.

Thanks for that input @Mashiro

I've just run a search on that TC-SUNBOW X3 model, nothing interesting came up except:
> random Reddit discussions on it, like these ones:
https://www.reddit.com/r/buildapc/commen...od_or_bad/
https://www.reddit.com/r/thinkpad/commen...ssd_brand/
> a Youtube video casting doubt about the company itself
https://www.youtube.com/watch?v=nNXertLCQ-Q
> a listing of TC-SUNBOW products on newegg.com
https://www.newegg.com/TC-SUNBOW/BrandStore/ID-206804
etc...

Not one professional review of any products of their products though... Thus it would seem that you're right in not trusting it with your data!
