Translation of Geek-speak please.

Every few years I take the notion to build another machine
and must relearn the wheel.
Is EIDE the same a UDMA?
What is UDMA in relation to SATA?
Are connectors different for SATA and EIDE?
Thanks

UDMA is the related to the electronic speed (as opposed to the physical
speed - RPM) of the drives: the ultra DMA 33 protocol supports burst mode
data transfer rates of twice the original IDE drives. UDMA 66 is twice that
again, etc.

EIDE (enhanced integrated device electronics) drives are parallel interface,
and do not use the same connectors as SATA (serial drives).

 

No,
EIDE = E-IDE = Enhanced IDE
UDMA = U-DMA = Ultra DMA

I dont know

Yes,
S-ATA has only some pinns for data and power.
E-IDE (P-ATA, Parallell ATA) has 40 pinns to data-transfer
and 4 pinns to power.

All different - parallel vs serial

Yes..

PC Guide is one place that has a discussion of official terms vs old
marketing terms

EIDE is a marketing term by Western Digital. There are 6 UDMA modes
0-5 corresponding to various ATA/ATAPI 4-6

SATA is the new kid on the block - for serial ATA as opposed to the
older ATA/IDE which is now called parallel ATA.

There's also a table in the wiki for the various ata/s 1-7 vs udma vs
eide http://en.wikipedia.org/wiki/Advanced_Technology_Attachment

 

It isn't.

as EIDE drives advanced the UDMA speeds went 33/66/100 and 133

Visit http://www.pcguide.com if you need some training. There is a lot
of info there but you can peruse the table of contents or do searches to
find your topic.

 

Thanks I've already Googled all terms but don't have the time
to read all 15,657 articles on the subject.
Came here hoping someone would have a succinct
definition of the terms.

You got them. So say thanks. And you still should read up on the new tech
before deciding what to put in your new box.

 

www.pcguide.com is *not* Google. I did see that the author hasn't
updated his site yet to include information regarding SATA (serial ATA).
