Earlier this year I thought I would try one of those ipod classics upgraded to a 256gb sd card, so I bought one from ebay. it was great for about 3 months, then it went crazy, the cover art was all garbled, and none of the albums would play. I tried a reformat in tunes and a resync. Now on some albums, in the middle of a song playing, it will stop and skip to the next two tracks. so it seems that this ipod is somewhat permanently messed up or corrupted. I see others on ebay, many with sd cards, and a few with ssd drives. Is there a difference in reliability between ssd based and sd card based ipods? which is better? or maybe the original hard drives are the best, should I try a ssd based one, or go back to the 160 gb original hard drive based one? I keep reading about how flash memory is more reliable than the hard drives in these ipods, but in my experince so far, the hard drive seems faster and more reliable. I am a bit dissapointed with flash drive based ipod so far, I only got about 3-4 months of good use out of mine, and now while it will play, it is unpredicable when or what screwy thing it will do next. I am not sure whether to try a ssd based one or not.
