Piccolo was a ~60MB, Fixed Block Architecture drive.
Aka the model 3310, iirc...

Nope, just your average 1" high 3.5' drives. It were the black ones
with the shiny gold band that existed of two halfs split through the
middle, vertically down the length of the drive with an adhesive cop-
per strip sealing the gap between the two halfs all around the drive.
They had a hole the size of a perforator hole in the body, next to
the serpentine channel cutout that formed the breather hole. Both
were covered with the same piece of clear thick adhesive plastic.
The headbeam was directly under that and you could see it move
when it was traversing the platters.
Later drives with case revision K-# 10 and above didn't have it anymore.
The same case was used on an even earlier drive, the 0662 iirc.
And no, Bigotwitch, they weren't Seacrates at all.
Manufactured by IBM Singapore Pte Ltd.

Piccolo was an 8" 64.5MB hard drive; six platters. The Piccolo was
the 62PC (I don't believe it was the 3310 - didn't all 33XXs have variable
blocks?) and came out in 1979. I believe it was only used as an embedded
drive, though ISTR it being used in the 308x service processor
(essentially a pair of 4361s under the hood). Lynn Wheeler over on AFC
would know for sure.

Wrong again. That drive you describe is an old 540 MB IDE
LOL Of course they were Seagates since they were the only manufacturer to
produce reliable drives at the time. The IBM drives during that era were a
major embarrassment.

More than 20 years ago I remember seeing low capacity (5MB, 10MB,
20MB) Corvus HDs that had clear covers. One advantage was that you
could see the divot marks resulting from head-to-disc contact.
However, I would think that such cosmetic frills in today's high
speed, high temperature HDs would be silly. Instead I'd be wanting as
much metal as possible to dissipate the heat.

Once upon a million years ago I put a clear plate on top of what
at the time was then a top-of-the-line 340 MB Seagate IDE drive -
and I know I was far from the first DIYer to do it because I got
the tip from, IIRC, a "Byte" magazine article.
Turned out to be a real yawner after watching the drive work for
2 or 3 seconds. I'm sure a lot of people are going to buy the
new clear-topped Raptors and after 3 seconds start thinking "I
paid an extra $50 for /this/ ?"

I've seen cases that are made of pure transparent acryllic. It might be
more impressive in one of these types of cases, where you can see the
entire guts of the system through the case. And yes, they're lit up
with blue-green lights.

Strictly speaking, SATA drives makes sence only for people who
are making a RAID array, because only in this case you would max
out the bandwidth of EIDE. Otherwise extra bandwidth that SATA offers
just goes unused.
Of cause another advantage of SATA is the nice sleek cable, that allows
for example to have an external HD that is on the same bus with internal
HDs, and improves air circulation. But I am not sure you would be ready
to pay the difference of price between EIDE and SATA just for that.

What price difference ? These days they often cost the same at
my most frequent vendor, www.ncix.ca. When aren't the same the
price difference is usually only 1% or 2% - and the IDE drive is
just as likely to be the one that costs a little more.

Clueless nonsense. SATA is point-to-point. There is only one drive per port.
Nope. Not possible with just (SATA) drives.
The only possibility to max out a SATA port is through an external RAID
controller that combines the bandwidth of the individual internal SATA
drive ports or SCSI or IDE buses into an external single SATA connection.
As is the case with all interfaces.
No interface is designed to be a bottleneck from start.
Utterly clueless.

Hi,
In 1980 and 1981, we worked with some of the Shugart hard drives.
They were rackmount and came in 15 MB and 30 MB sizes. The platters
were about 15" and the whole platter side of the drive had a clear
cover. Anybody remember those? Actually, I guess this is a little off
topic since they weren't IBM hardware. We used them for rackmount
Point-Of-Sale systems with a custom board containing an embedded 8080,
some prom, some RAM and I/O. Later we went to the rackmount S-100 CP/M
and MP/M systems.
