I’d be curious to see how much cooling a SAS HBA would get in there. Looking at Broadcom’s 8 external port offerings, the 9300-8e reports 14.5W typical power consumption, 9400-8e 9.5W, and 9500-8e only 6.1W. If you were considering one of these, definitely seems it’d be worth dropping the money on the newest model of HBA.

I’m definitely curious, would only personally need it to be NAS + Plex server for which either of the CPUs they’re offering is a bit overkill, but it’s nice that it fits a decent amount of RAM, and you’re not forced to choose between adding storage or networking.

Single-sided drives can be up to 4TB though, no?

To expand on @doeknius_gloek’s comment, those categories usually directly correlate to a range of DWPD (endurance) figures. I’m most familiar with buying servers from Dell, but other brands are pretty similar.

Usually, the split is something like this:

• Read-intensive (RI): 0.8 - 1.2 DWPD (commonly used for file servers and the likes, where data is relatively static)
• Mixed-use (MU): 3 - 5 DWPD (normal for databases or cache servers, where data is changing relatively frequently)
• Write-intensive (WI): ≥10 DPWD (for massive databases, heavily-used write cache devices like ZFS ZIL/SLOG devices, that sort of thing)

(Consumer SSDs frequently have endurances only in the 0.1 - 0.3 DWPD range for comparison, and I’ve seen as low as 0.05)

You’ll also find these tiers roughly line up with the SSDs that expose different capacities while having the same amount of flash inside; where a consumer drive would be 512GB, an enterprise RI would be 480GB, and a MU/WI only 400GB. Similarly 1TB/960GB/800GB, 2TB/1.92TB/1.6TB, etc.

If you only get a TBW figure, just divide by the capacity and the length of the warranty. For instance a 1.92TB 1DWPD with 5y warranty might list 3.5PBW.
