No, see the video i pointed you to... it's part of the SAS-3 spec, and also SATA 3.3 spec. the 3.3V was never really used by HDDs, even when available on old SATA power connectors. the new spec has reallocated 1 of the 3 3.3V pins for "power disable" so you can use software to hard reset a hard drive; saves data center operators from sending someone out to a rack to unplug a drive.so is this only only HGST sata hdd and sas drives? i mean if it's the new industry standard, then why are all the current psu still have 3.3v pin 3? are psu manufacturers behind the curve?
Why is a lot of psu manufacturers still have 3.3v wires to their cables?No, see the video i pointed you to... it's part of the SAS-3 spec, and also SATA 3.3 spec. the 3.3V was never really used by HDDs, even when available on old SATA power connectors. the new spec has reallocated 1 of the 3 3.3V pins for "power disable" so you can use software to hard reset a hard drive; saves data center operators from sending someone out to a rack to unplug a drive.
because this is all a relatively new change for the consumer space (SATA 3.3), but even in the server space (SAS-3), server backplanes haven't provided 3.3V as far as I can remember...Why is a lot of psu manufacturers still have 3.3v wires to their cables?
what's the brand/model of the SAS HDD?Spin right up after pin 1-3 covered but stiill not recognized by adaptec 31605... will have to try on another adapter
HGST Ultrastar 7K6000 HUS726040AL5210 4TB SAS 128MB 12Gb/s 7.2K 3.5" Lot of 10 | eBaywhat's the brand/model of the SAS HDD?
If you're comfortable running a live usb/cd boot Linux distro, I just fixed up my HDD testing script 'bht' to support SAS drives:I need to run complete surface write and read test on them to verify . i guess that will more than double their smart stats after i do that? ;(
the only other thing is that hd sentinel is not free.... $29 for the pro ver..... but it will let you run multiple HDDs test at once. Anyone knows of a free surface test app that will work with sas drives?
what is cheap to you? 6Gbps options are plentiful and can be found between $20-$50. Are you looking for SAS HBA? or SAS RAID? Anything with LSI chipsets SAS2008/2108/2208/2308 should do it, depending on if you want HBA or HW RAID.good cheap 8gb or 12gb at least 8 port sas controller recommendation anyone?
cheap as in less than $40...how about these: sas 6gb 8 port | eBayIf you're comfortable running a live usb/cd boot Linux distro, I just fixed up my HDD testing script 'bht' to support SAS drives:

It runs badblocks on all the hard drives, which runs 4 different pattern write/read/verify tests across the entire disk.

12Gbps SAS is usually more expensive... the cheapest I've seen is around $70...
so, for your price range, and wanting HW RAID, I would look at controllers based on LSI SAS2108 chipset. Things like LSI 9260-8i, Dell H700, IBM M5015, etc. You might also need a battery, cache module, and some of them require a "key" to get fully featured RAID.

you recommend anything on that page? it needs to use the sff 8087 cable .... would like to have raid 5 also if possible.
Yes, I believe they work in non-Dell systems, but some times you need to apply tape to pins B5/B6. I mostly have used these cross-flashed to LSI IT mode firmware though. Also, they do not support HW RAID 5.has anyone got these dell perc h200 h310 to work in a system that's not dell?
yeah, if you just want a cheap HBA card instead of a RAID card, there are plenty of options:if i just need a simple controller to just use 8 independent sas drive with no raid would something like perc h310 be good enough?
