Which SSDs do people rely on? Considering PLP (power loss protection), write endurance/DWPD (no QLC), and other bugs that affect ZFS especially? It is hard to find options that do these things well for <$100/TB, with lower-end datacenter options (e.g., Samsung PM9A3) costing maybe double what you see in a lot of builds.
- nightfly 1y agoZFS isn't more effected by those, your just more likely to notice them with ZFS. You'll probably never notice write endurance issues on a home NAS
- privatelypublic 1y agoQLC isn't an issue for consumer NAS- are 'you' seriously going to write 160GB/day, every day?
- magicalhippo 1y agoQLC have quite the write performance cliff though, which could be an issue during use or when rebuilding the array. Just something to be aware of.
- dwood_dev 1y agoThe 2.5Gbe network writes against a RAID-Z1 config of 4 drives puts the sustained write speed below that of most QLC drives. Recovery from a lost drive would be slower, for sure.
- privatelypublic 1y agoSame response, basically: take a 1000MB/s drive, it takes 120s before it drops down to 20MB/s... where are you going to source 120gigabytes- on a routine basis. Not saying premium drives dont have their place- but for 95% of people $200/TB ($100 premium over lower tiers) is a waste.
