Greetings,
I am interested in any good rackable JBOD enclosures people in the community are using.
I'd like to know things like:
I am currently using an HP MSA70 (25 2.5" drive bays, connected to an LSI SAS controller via SFF-8088). It has it's built-in expander allowing the 25 drives, and supports pass-through, so you can connect two of these in series I believe (using HP P800 or other supported cards, need clarification on using LSI, though I suspect it doesn't care).
Pros of the MSA70:
I'd like to know if you can stuff consumer 4TB drives in HP 3.5" sleds and jam those in there?
I am curious is anyone has tried this?
Scope of this discussion/interest
This isn't a 'Should you use external?' discussion; It's a 'You're doing external, so which products are the best options and known to be working well' discussion.
I am interested in options for adding drives when you have no more capacity in your case. I'd like not to see arguments of external versus internal (such as high capacity SuperMicros). I think that should be a separate discussion if it should be discussed.

I'd like to know things like:
- What external enclosures are you using?
- If you're using SAS or SATA in your enclosure?
- The connectivity method you're using (SFF-8088, etc.)?
- The type of drives you're using (Consumer drives or new enterprise/ebay enterprise)?

Pros of the MSA70:
- Drive density is OK. 25 in 2U (there's probably products that do better, but are they as cheap?)
- eBay cost is decent-ish (~$250)
- Everything (drives) is hot-swappable assuming you have a good controller, no downtime
- Cabling is minimal with single SFF-8088
- Plenty of used spindles everywhere (SAS and SATA)
- 2.5" drives are more expensive for much less capacity than consumer drives
- You'll need more drives for capacity unless you buy really expensive ones, though that can lead to better performance in certain cases
