^^^^ Good analysis. The prices have to come down and the reliability proven before I would leave a technology which works for one I am not sure of and is way more expensive.
As it stands now from the tech journals discussing HD to SSD plug-in replacements, the way flash storage works is very different than HD protocol standards now in place, and the translation mechanism for SSD to work consistently into HD sockets is problematic as NO standard protocol for doing this exists.
This leaves the method of translation to the flash device manufacture and from what I can tell it is a struggle without dedicated proven interface ICs specialized for this task. This means the SSD plug-in equivalent may or may not work so reliably under
all conditions now expected of HD standardized products on the market.
So it may be wise at least for the less technically inclined among us with limited budgets to let the engineers and OEM market prove the practicality and reliability of such converted storage devices and see what the market brings.
For tapers having backup decks for doing parallel recordings to fully test a SSD converted deck while not risking the recording, this thread might be read by many with interest to know what does consistently work well with SD-744T/Edirol R-4 PRO 4-channel, and the two KORG DSD models.
So hope to have this discussion continue with more SSD device conversion postings both of woe/triumph from DIY tapers, and the deck makers trying out HD-to-SSD conversions.
