Not too difficult, power connector on sata scuppered my score !

It tells me that I may have a bad bookmark when I hit your VOTE button. This is even worse that the questions that have different numbering than the answers.

No wthat was an entertaining quiz

(I got the SATA power connector question wrong; said it was SAS) What amazed me is that nearly 10% (9%) of us thought that SATA ("Serial Advanced Technology [AT] Attachment") was parallel (even though ATA was retro-named to PATA ("Parallel...") just to emphasize that distinction), and 14% thought SAS was parallel (even though SAS means "Serial Attached SCSI [Small Computer System Interface]")!

Not bad, considering I've never seen SAS...

I thought the IDE interface was developed by Conner Peripherals? I remember when our company bought some Intel 386 66Mhz Compaq PCs with 80MB Conner hard drives and 1 MB RAM for $10K (ouch); they were state of the art for personal computers at the time.

I thought about spelling out all the acronyms, but worried it would give this questions away.

Connor developed the 3.5" form factor for hard drives.

When I saw "Traditional" I though "Obsolete" and expected to see MFM/RLL too!

my first encounter with SCSI was with a 50 pin cable 2GB HDD and 3x CDROM

It would be scary if you had to know those as a contemporary IT professional. :0

"Run Length Limited" or "Modified Frequency Modulation" wouldn't give much away... ;-)

My first encounter with SCSI was with a 50-pin ribbon cable to a 52MB (yes, Mega) hard drive, and a 25-pin DB-25 connector to an external 2x CDROM drive. This was on my Amiga A2000HD system.

Why did you have to bring that up? Now I remember the External SCSI connectors (and the effing Traveler) for the Zip and Jaz drives, something I'd managed to forget for over a decade. X-(
