Discussion Hello from a storage enthusiast with a new (to me) SAS project!

[fohot42001]

Hi everyone,

A friend pointed me to this forum, saying it's the best place for in-depth hardware discussions, so I'm excited to join the community!

My name is fohot42001, and I've been tinkering with servers and enterprise hardware for a few years now. I mostly focus on building homelabs and resurrecting retired enterprise gear. I'm always knee-deep in something, whether it's setting up a Proxmox cluster or messing around with ZFS.

I just picked up a piece for my latest project that I'm pretty stoked about: a SAS 12Gbps SSD 480GB MU 2.5-Inch drive. I'm planning to use it as a fast cache or log drive in my Dell PowerEdge server.

I have a couple of questions I'm hoping the experts here can help with:

1. Controller Compatibility: I know 12Gbps SAS is backward compatible with 6Gbps, but will I see a significant real-world performance hit if my HBA (an LSI 9207-8i) is only 6Gbps? Or should I really be looking for a proper 12Gbps HBA to unlock its full potential?
2. Drive Longevity: This is a used enterprise drive. For those of you who have used similar refurbished SAS SSDs, how has their health and endurance been in your experience? Any tips on what to look out for?
3. Use Case: Given that it's "only" 480GB, what do you think is the ideal use for a drive like this in a homelab? SLOG? ZIL? Hyper-V cache? I'm open to suggestions!

I'm looking forward to learning from you all and contributing where I can. Thanks for having me!

Best,
