I've also had to deal with their lack of Canadian RMA for 2 SSDs. Had to go back and forth with them and trying to convince Amazon and the Amazon seller to replace the defective drives.

Not buying any more Samsung memory products due to their essential non existent warranty in Canada

Took about 5 months of endless back and forth to get them to replace a defective SSD in Australia too, despite very clear consumer law guarantees here obligating them to help. Absolutely hopeless company to deal with.

Buy through Memory Express if you've got a store nearby, just need to keep the receipt for the warranty period. They have a price matching policy for items that have the same SKU as well.

MemEx is an authorized dealer so they'll take it back and send it back to Samsung for warranty work if you buy from them.

Seems like an abbreviation for a USD$400B+ company that manufactures SSDs, but with the commenter not specifically mentioning (presume, smartly, to avoid SLAPP lawsuit/libel).

Could be Seagate and SanDisk too ...

I expected this to be SanDisk. I bought one USB from them and after a few writes it locked itself from writing further.

Apparently I'm not alone and the only fix is to throw the thing away.
