Re: [LUG] Bah! Disks! Bah!

 

Quoting Max Siegieda <maxsiegieda@xxxxxxxxxxxxxx>:

Aha, that's my cue! There are a few methods of cutting the price of larger
SSDs although they are somewhat risky. Remember the
manufacturing efficiency boosting method of making a high end product then
lopping bits off? It's in use with SSDs too, for example there's a certain
Kingston drive that uses exactly the same controlling hardware as the very
nice Intel X-25M 80GB (which tend to cost about £175 iirc) however it has
half the NAND chips meaning slower speeds and lower capacities. It is
possible to buy these chips from places such as Digi-key and
surface-mount-solder them back on giving you the high grade SSD for £125.

Interesting, shame my soldering skills are how can I put it... non existant. I'm sure anyone good at soldering though with the right kit could possibly manage it.

If that seems a bit too risky and you have the time you could always create
your own controller chip using an FPGA with plenty of pins, a friend of mine
was looking into it for creating a physical RAM drive and it seemed like the
process was transferable, using his chip switching method where only one
chip is addressed at a time it would be possible to have hugely extendable
drives for the price of a cable and some flash memory which was iirc £9.50
per 8GB chip and £20 per 16GB chip, the only issue is of course that random
reads/writes suffer a bit but a decent cache can solve that.

Again, over my head, I'd have thought that would be one for the DC Hardware list. I've looked at FPGA programming but it looks a tad too complicated for me (although I do like some of the stuff which has been done with FPGA's such as building a Commodore 64 and Amiga on a chip). I believe Jeri Ellsworth was responsible for the C64 on an FPGA, I remember a couple of years back watching an interesting interview/Q&A session with her where she discussed it all.
