Does a SAS to USB adapter exist connecting a SAS drive to a desktop PC for short term needs?

Is there a way to connect a SAS hard drive to (preferably external) USB A or some other way to format it as a stand alone drive / wipe it / etc?  NOT trying to read data from when it was in a server / connected to raid controller, etc.  Looking to start new with the drive.

I have something like this for SATA.  Looking for something like this but for SAS:

I'd rather be able to connect to the external USB, but would you think this would work?  The description says 'Allows you to connect a SAS hard drive to a SATA controller that supports SAS drives'.  Any idea if most dell optiplex desktops support sas drives?

Reading the reviews for that item on amazon , it seems no, desktops don't handle SAS drives.

So what's the cheapest SAS controller and is there one that connects via USB?  Yes, totally not what SAS is inteneded for (many drives, RAID). I am just looking to be able to wipe / format / write new to it as a JBOD... and bunch being one : )

Interesting question, indeed usb-sas doesn't exist.
And i found similar cables like you did.

LSI makes PCIe adapters for SAS , like 9211 ~$110,-- on amazon...
This does require a cableset and drive bays. ... probably not a high performance solution.

So you will need some PC chassis to handle the internal only connections. & powersupply to the drives
Dr. KlahnPrincipal Software EngineerCommented:
The last time I went looking for one (three months ago, a similar question was posted) I was unable to find a USB adapter that would handle SAS drives.  An El Cheapo PCI or PCIe SAS adapter is probably the way to go.

That previous discussion is at the link below:

Regarding SAS drives on SATA adapters, so far as I know this does not work.  The other way around (SATA drives on SAS adapters) does work on some adapters.

Such a thing can't ever exist.  It would not be economically viable to produce, and I know for a fact no chipset exists.

thanks guys!  OK, next step, along what you were saying Dr. Klahn.

What's the cheapest SAS controller card that will work in a Dell Optiplex 780 mini tower (full size cards WOULD fit).

Here's a picture of the mobo.  I tried looking at Dell specs for the MT 780 to see what you'd call those slots...  And got confused. It uses the integrated to the mobo video output.  I see 4 connectors there in the expansion slot area.  All are empty now.
You can pick up a used SAS controller on ebay for $25.  Just make sure it is a JBOD, non-RAID, and has appropriate cabling).   Yo should get the LSI branded one not the Dell, HP, or IBM branded. That way you will not have issues with firmware & drivers.

david - thanks.  but 'just'  : )

seems the ones I saw say raid.  I would have thought they all can do jbod.  It's raid that might not be doable? (ie, it specifically CANT'T say it does RAID?

And any of those connectors on the boards will fit the PCI slots I have?.

and appropriate cabling - just make sure then end in SAS connector? I was reading something about battery pack. Is that for power or to retain settings? If for settings, I don't need that.
No, the ones that do RAID typically carve out a few MB starting at physical block 0. That makes them unacceptable because you don't have access to the entire disk.  Look for LSI MPT-class controllers that use the "IT" class firmware.

Here is one for a whole $16

Any of the 3801 will work fine. Find one with the right bus interface.  In fact any 38xx family controller is going to be non-RAID,  and they make controllers that even work with PCI-X buses.

Dell Optiplex 780 mini tower

What a coincidence, I'm sitting six feet away from one.  The "MT" configuration motherboard has one black PCI Express and two white PCI slots.  Any PCI Express card of width 4 or less will work in the PCI Express slot.  Any PCI card will work in the PCI slots.

Be sure to get an adapter card that has drivers available for your target operating system.  SAS was targeted at servers and it is not out of the realm of possibility that there might not be drivers for "consumer" versions of Windows.

Watch out for power supply issues.  The Opti780 power supply is very weak for a system built not that long ago.  Quoting myself from a page on the subject:

The Crappie Power Supply (Not My Kettle Of Fish)

Now (discounting problem #3 below) the power supply in the 780 isn't really all that bad.  I've seen worse, although not recently.  However, this system was sold into the business market.  Admittedly the low end of that market, but nonetheless in such systems one reasonably expects a decent power supply and this one just falls short of that mark.

I figure it would have cost about $5 more in manufacturing to have installed a decent power supply.  That extra investment would have eliminated all the issues below.
TCPS: It's Underpowered

A 250 watt power supply was well under the standard of 350 watts even in 2010.  This one isn't even 250 watts, it's 240.

The motherboard and BIOS support Core 2 Quad CPUs, but 780s generally shipped with Core 2 Duos.  One reason is that the system is borderline hungry for power.  Upgrading a Core 2 Duo E5400 (2.7 GHz, 65 watts) to a Core 2 Quad Q6600 (2.4 GHz, 105 watts) means that CPU power consumption goes from a third of the power supply to nearly half of it.

That doesn't leave much power left over for other components - the motherboard itself, the memory, the CD drive and the disk drive.  And very little for an add-in GPU.  Which brings us to ...
TCPS: It's Underconnected

It's pretty much "tough luck" as far as installing anything that uses Molex connectors.  There aren't any.

Likewise, there's no installing a GPU that needs external power – not even the slightest amount of external power.  There is no way to install anything requiring auxiliary GPU power.  That restricts the selection of add-in GPUs to very basic units that can satisfy their power requirements from the PCI Express socket.
