Struggling to get 20MB/s sequential write. Their TBW count is low so it's not an issue of excessive write cycles. I've searched around and established they are just really bad SSDs. They also don't support SMART self-tests, which seems like a really cheap thing to do. I'm further confident that the problem lies with these SSDs because there is a pair of much better SSDs in there and they perform as I would expect. However, the use case for this storage is for lower cost so it's not an option to just buy more of those. So, could anyone suggest a decent low end (consumer/prosumer market) SSD model that is known to work well without terrible firmware bugs under Linux, preferably with power loss protection? Low write endurance is fine. Capacity of 4TB ideally. Thanks, Andy
