Once upon a time I would have bought this in an instant...

Limitations - I'm not sure they support a drive size larger than 2TB,

I'm pretty sure I read someone with 2TB drives stacked in it - it could have been from a previous Ebay listing.

Ha - look at this thread

I was more looking at 3GB/s as a limit which implies it will have the usual >3tb issues as well.

hum, if we change the HBA, maybe less limitations?

J4500 are based on LSI expanders (x36). With an good LSI card, connected with 4*3Gbps (yes, JBOD -> HBA = 4*Uplink speed, i've already a lot of dell/custom racks in 4*6Gbps with one SAS cable), so... 12Gbps.

And then, maybe 4/6/8/10/12.. TBs drive will be working, i don't think SAS expanders are limited based on disk model, no? :/

If I remember correctly Sas1 (between hba and HDD/SSD) uses 32bit for adressing. With 512b Block Sizes you are Limited to 2tb , with native 4k Block Sizes to 16tb HDD/ssd.

Signaling is still an issue.

If you had a maximum of 2TB drives that gives you 288TB of capacity, or a single 24-bay full of 12TB drives worth. You have less drives to deal with, newer components, and 24-bay enclosures are inexpensive these days.
