Hi Tim,

thanks to you and the others for answering.

Good to know. This really opens up the possibility of buying 3 or 4TB
Hitachi drives. At least the 4TB Hitachi drives are 4k (512b emulated)
drives according to the latest news.

It has actually.

So what you are saying is that something like this will do the trick?


If I interpret this correctly I get a SFF-8087 to SFF-8088 bracket, connect
the 4 port LSI SFF-8077 to that bracket, then get a cable for this JBOD and
throw in 4 drives? This would leave me with four additional HDDs without any
SAS expander hassle. I had not come across these JBODs. Thanks a million for
the hint.

Do we agree that for a home NAS box a Hitachi Deskstar (not explicitly being
a server SATA drive) will suffice despite potential TLER problems? I was
thinking about Hitachi Deskstar 5k3000 drives. The 4TB seemingly came out
but are rather expensive in comparisonŠ

Kind regards,
