To piggy back on that, many controllers have different amounts of background garbage collection. I second the OWC recommendation. With good garbage collection and keeping say 10% free, you should be very happy with performance over time. That also said, you can saturate your ata 66 bus with a fast compact flash card, so a cheap IDE to cf adapter and cf cards may be a cheaper way to go with similar performance. For heavy use, I would still think OWC.
None of that advice is from experience. Just from prior research I've done when considering buying a used cube for fun...

Thanks.
I was peeking towards a Samsung 830 series SSD. It does _not_ use a Sandforce
controller, but—if you believe some reviews out there—something very similar.

My understanding is that garbage collection is something completely different
than ATA Trim. I.e. garbage collection also “optimizes” garbage. If a bit is
not zero on the media, then it is ultimately also optimzed, whereas SATA Trim
can be seen as the second half of the rent: it tells the controller which
“used” bits can be irgnored when optimizing all the data bits (what is called
“garbage collection”).
If only I could be certain that I got this right…

I used a CF (compact flash) card with one of these IDE to CF adapters in my G3
B&W. It was fun, but it also was a bit of a slowdown, even on the slow IDE bus
the G3 B&W has. Maybe it is also because I used a slow CF card… Anyway, I
“upgraded” to a SATA-to-IDE adapter: I’ve had a spare 2.5″ SATA drive that was
eager for some use. :-)
With flash other than SSDs the problem is, that—like e.g. CF—it doesn’t have
ATA Trim or Garbage Collection at all. When in heavy use (meaning that a lot
of files will be moved/copied/deleted) it will most likely wear out, equals
slow down, quite rapitly…
On my G3 B&W the CF was always half empty and I didn’t do a lot of file
moving, so this didn’t happen…

I really appreciate OWC as a good quality brand. That said, I don’t own a
single OWC item, with the one exception that I happen to have a 1.4 GHz G4
Accelerator card (that I don’t use that much really).
For the most part, they (OWC) use what is available out there. To use any
other SSD with a Sandforce controller is the same difference IMHO.
> None of that advice is from experience.
Thanks for your good judgement on this! It helped me get my intentions
clearer.
If I’d choose now I’d most likely go for a Samsung 830 series SSD…
unfortunately I’ve decided to wait a bit more until the prices drop further…
and then I’ll buy two SSDs at once: one for the Cube, and one for my tower
(which is an AMD powered PC).
Thanks, both of you!

If you should ever do get a Cube: it is really an awesome peace of technology!
What really “breaks” its brilliancy is a loud 3.5″ HDD (like the original
one). But this can nowerdays be easily fixed…

In my experience, TRIM is not a must when you leave around 15%-20% free
space. If it gets too laggy, you should simply reformart the HDD.
This said, I had an Intel X25-M operating for 18 months without TRIM
support before performance dropped noticeably.
