Maybe not... depends on the workload and performance requirements.

R/W cache may not work how you expect. Please make sure you read the details about it first before spending money.

Please follow the forum rules. Create threads with good titles and postings that have some substance where we clearly understand what you are asking, your title "if have 512g-ram" doesn't help you out at all. I can change the title but just need to know what you are asking. Are you asking for advice on how to configure a cache, asking if you need a cache? Something else? We need to know what version of TrueNAS/FreeNAS you are using and your use case of your system as well. Make it clear to us so we can provide the best advice to you.
