Warranties & Guarantees - They are an indication of the faith manufacturers have in their product, that's all. They mean close to, or absolutely, zero when it comes to your data.
SSDs sold on Chinese retail/wholesale sites are cheap for a reason, they frequently use sub-standard components, are DRAM-less (slow), QC is questionable, and you have little to zero chance of getting any rectification under warranty in a decent time frame, (if at all) ... but
... they are cheap, fast read storage for data you don't care about and as such they have their place if you recognise them as such
.Just a note here:
I have nothing against these Chinese sites, most of my stuff comes from them but you have to know what you are getting and set your expectations accordingly, (mine are non-existent).
As I said, I have a few of these cheap SSDs and they're great as a fast USB drive, game drive, or anywhere else I don't care what happens to the data, (even though I just installed one in a security NVR).
If you want known reliability, (and a warranty that might actually mean something), then you basically need to purchase brand name products from Samsung EVO, SanDisk Ultra, WD Blue, Kingston, Crucial MX, Seagate , Toshiba, etc - if all you are interested in is specs then look at what they offer to see what you should be looking for.
1TB Samsung EVO or QVO SSDs can now be had for <AU$200 (~US$140) if you look around - your main problem is you live on an island and I would think that shipping costs are going to be a big factor in any decent SSD/HDD you buy online or locally.
