BS - tell me this in 7 years.
The "Olde" Hitachi ~music~ HDD has 2400 DAYS (olde Hitachi ... before IBM "deathstar's)
of operation with NO re-allocated sectors.
It was throw into a dumpster from a second story window 5 years ago.
My first SSD (sandisk) had thousands of bad sectors and died in a year.
My samsung SSD has a couple already and still works ... but this
is normal for it.
SSD's will be perfected in a few years .... maybe with some quantum
"help" ???

That Hitachi I have still works, its like 7-8 years old but its just really corrupted/bad sectors.
I don't know WD Blue's you could get for pretty good deals. I can imagine the Blacks are just as nice. Just kinda picked one really. Only a little over a year old no problem's at all.
I didn't want to go Seagate because everyone is saying yeah they are dieing and ****.

Firmware is the key , even the newer HDD's will try to "be easy" on any
one sector in a high use environment.
Seagate and WD are BOTH becoming POS ,unless you buy a 5400rpm drive -
Variable RPM drive ....
that is made (and warren-teed) for 1 million MTBF -5 years.
You now pay a premium for what used to be standard.
Go for a single/dual platter - lower capacity drive. I would rather have
4 - 1/2TB , or 2 -TB drives than 1 - 2 TB drives.
Also , try to find a non -chinese made HDD !!

Shame on me...
...I was just kidding around about leaving the
seminar with the book, cross town book fair,
arrest--5000 comedians out of work and that
was my feeble attempt at humor, I won't quick my day job.
Remind me next time to park my writers imagination at the door,
especially after a few cocktails during weekend rest and relaxation.
Now that I've gotten that out of the way, in reference to the second book
from the Gutenberg Press, please find the pop up on the attached page:
thumbnail and link as follows:
Euclid's Geometry with Pop Up
I placed the pink triangles behind the sides so they would
show up better when scanned in.
This was also from Tufte (ibid.).
I hadn't thought about the moire effects in years.
Tufte was discussing the line per inch included with
Chartographic Relief and how Swiss maps are so excellent.
The reason for bringing this up to begin with was the fact that
video and audio are forever linked as the Moving Picture Expert Group (MPEG)
include both video and audio compression schemes. Dithering used to be a graphic
type function.
So, if we are doing these things with are audio, it might be helpful to understand
where these things came from. Once in the digital realm it's all 0s and 1s.

Working on real problems? Doing real experiments to see what's important and what's not? And then working on the real problems? Refusing to be associated with frauds and nuts? Earning the respect of serious engineers and scientists through integrity and real achievement?
Nah, that's CRAZY talk. Sorry, what was I thinking?
yes. fake it in a computer = blue screen. Only CD cannot fake it.
Computer data files will be corrected to perfect every time. Not so with CD which cannot go back and reread but it doesnt have to as it wont crash or go blue if it can be filled-in or faked now and then.

Just to make sure that I am understanding Esperado correctly,
when you mentioned that you were doing and insert edit
right for the following example?
Track length: (10)
----------
Track length to be inserted at 3rd point: (2)
**
New track result: (12)
---**-------
This is where your decks make the dull sound depending on the
settings right?
I know this is rather late in the discussion but just wanted to make sure
as there are only about 65350 posts here and if have to do something sometimes
it takes a while to catch up.
Thank you for your understanding.

Where it does get complicated is if interference from the digital circuitry in the CD player is impacting the analogue side of things in any fashion. The more C1 errors, the more digital chatter, and hence potentially poorer sound if overall engineering is not up to scratch - hence the overly engineered CD transports having a positive influence on perceived SQ, in many cases.
I'm reminded of a "boom box" I bought to replace one that had only a tuner and a cassette player. The cassette player having failed in my 1991 Honda, I wanted something to play music on road trips besides the car's tuner, but the inverter I bought had so much noise in the AC output that it rendered the tuner/cassette player boom box incredibly noisy. Batteries were an option but they didn't last long playing cassettes.
So I had high hopes for the new boom box with CD player. Things were fine if I started a CD when the car was stationary. But if I tried to change a disc when I was on the road, it refused to play. The vehicle vibration was too much for the tracking servo ever to get a lock. How much work the error correction circuitry was doing when the disc played after being started with a stopped car I have no idea, but it may have been a bunch.

SSD's do the same thing as Hdd's. Nand can only be written to X times ,
then a sector is bad and marked.
Since a SSD sector can not be written to as many times as a mechanical one ,
the SSD firmware will randomize the writes so no one sector gets "assaulted"
too often.
SSD firmware is almost a mini operating system.
But ... at the buffer RAM output , only perfect data emerges (or you get
a perfect blue screen).

What about written once and X read backs. How does it stand up?
davada,
I may be wrong but from what I understand it is only the rewriting of the same cell that has a limit, not just playing back the same cell over and over. I don't recall if it is something like 500 writes before a cell is toast but it is something like that. I don't think if you write to the drive and keep retrieving that same information without change that there is a problem.

That is my turn to do not understand what you said.
Let me-try to explain my point. During years, like everybody, i believe, i was fighting to have all the instruments with all their presence in the mix. We used to add instruments little by little, one after the others to construct the scene. Bass +drums first, then rhythm guitar etc... More you add instruments (tracks) during this preparation, and more their presence (liveness) are affected. (more or less depending of the studio). During years, i thought that was some kind of mask effect, or inter-modulation. That obliged to work on the tonal correctors to compensate this and recover the sound we wanted. I mean an instrument, perfect in solo, sounding duller in the mix when everything together.
One day, i had the idea to compare the same track, on my desk, routed alone in a stereo bus with the same, but together with 32 muted slices added in an other stereo bus. The difference was obvious to everybody asked to give their opinion. Later, i replaced the original OPAs of the stereo bus of this big CALREC mixing desk of my studio by OP260s. The same test made no difference, this time (apart noise difference).And, cherry on the cake, the separation was better between all instruments, more air, more easy listening.
Now, i'm may-be wrong on my supposition of the causes of all this, but i don't think.
Anyway, digital desks solved this issue (despite others corrector side).

hehe, i had build in my car a very efficient suspension (really floating) under my minidisk player at this time for the same reason. (Four cylindrical springs dumped with plastic foam inside.)
No more drops, even on pavement.
Makes sense to me - the OP260 has diamond buffer output stage, fairly unusual in an opamp which means its PSRR when loaded holds up better. Page9 of the DS shows its HF (20k and up) PSRR is several dB better than any VFB amp with a 10MHz GBW (like 5534). Also worthy of note is this plot shows the loaded PSRR (2.5k feedback resistor mentioned).
