right now iam really frustrated. I bought a ipod classic 6th gen 80gb as defective. The hdd is surely broken. I also bought a Kingspec SSD 128gb (KSD-ZF18.1-128MJ).

The SSD is recognized in the diagnosticmode but on startup i got the red x. Is my purpose even possible or may be anything else broke??? Many thanks and sorry for my bad english ;)

How do you know the HDD is broken? It could be the logic board problem. If it works with another good HDD, then you can conclude the problem with the HDD. But if the problem is with the logic board, then anything you do for the drive (HDD or SSD) won't work.

You didn't mention anything about connecting the iPod to iTunes after the hard drive swap. Did you put it in recovery and connected it the the computer and see if iTunes can see it?

I thought the hdd is broken, because it wasn't recognized in the diagnostic mode (failed to open device) and i don't felt it spinning. When i set the ipod in recovery mode the ipod is recognized by itunes. It says to restore and after that the ipod restarts and end up with the red x. So i ordered a Supertalent SSD today and check if it will work. Many thanks for your replies!

Can someone who successfully installed the SSD confirm if copying files to the SSD is much faster than copying files to HDD?

Thanks

i just tried installing an msata into a 7th gen and it was a no go. tried many formating types 

FAT32 5 times twice from a mac

NTFS

Extended Journaled

It shouldn't be.. You are bottlenecked by USB bandwidth not hard drive speed when you are copying files to the IPod.

When using the iPod, seek time and latency are among the main advantages of the SSD, and that's harder to quantify since you're usually comparing fractions of seconds to fractions of seconds; it's easier to say the iPod feels faster with an SSD on board, even though the basic functions (navigating menus, listening to music) aren't affected by the type of drive installed.

There could be lots of explanations for that. USB 2.0 speeds are 60MB/s. I couldn't find the specs on the stock Ipod HDD, but I found found a cheap Toshiba replacement drive that was 52 MB/s at 3600 RPM, the stock HDDs are 4200, so the transfers speeds on the stock HDD should be just above USB 2.0 speeds. The difference in time could be computer related, or could be because of fragmentation, or maybe the HDD really is slower than the USB, who knows. Theoretical throughputs are theoretical. Honestly though, since USB 2.0 is involved, probably transfer speeds shouldn't really be factored in to the SDD decision because they won't be sped up very much.

I completely agree with the second part of your post. Well said. Also, I feel as though not having to worry about shock is a big big advantage. Battery should be better. These HDDs are so slow that I really don't know how much difference there is in battery life. I'm sure there's information in this thread about it.

I'm not trying to argue with you . They were also done 2 weeks apart. You could have had other processes running in the background. Your antivirus or Windows could have been updating in the background. You could have had other devices using the same USB header.  

I'm quite thoroughly frustrated at this point. I obtained two "non-functioning" 256gb Duradrive ZT2 drives. The drives wouldn't detect under Windows, however some investigation on Linux found a corrupted MBR. I secure erased both drives, and re-initialized them with a fresh MBR. I then installed both drives into the same iPod Classic, neither drive gets past the Red X, both drives detect fine, and both drives list their serial number. Neither drive lists SMART information (though I don't think they are supposed to) From there, I decided that it was likely due to the lack of a proper partition structure on the drives, so I went ahead and DD'd the contents of the stock hard drive to the SSD; the iPod stays on the Apple logo a lot longer for the first boot afterward, but then goes to the Red X again. I'm thinking this could be due to that I never put the ipod in windows mode, nor did I rockbox it first.
Any pointers on where I should head? What else might I be able to try?
I understand that the OP states that the 256gb drives are 5v, however as other users have confirmed, as well as Supertalent and their Datasheet says: These are 3.3v drives. The iPod is providing sufficient voltage for the drive to come online - the detection of the drive and its serial number are evidence of that. Also, this is a *brand new* iPod; the stock HDD still works when I put it back in, so the issue is specifically with the SSDs. I'm willing to try pretty much anything.

I think you should have someone with an iPod video try one of the drives, there's a chance it has something to do with your iPod being an iPod classic.

Dang, I have two spare 6g iPod classic motherboards, and a 7g iPod classic but no iPod video parts. And unfortunately, I don't know of anyone around these parts with an iPod video that would be willing to let me tinker with it. I'm gonna try rockboxing it and see if I can get rockbox to boot with one of the drives installed. I may end up tinkering around with a hex editor or look into the emcore code to see if I can circumvent what I think is causing the iPod classic's to not recognize ssd's. I have a feeling the lack of SMART reporting on *most* 1.8" drives may have a lot to do with this.
