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. http://www.hardwaresecrets.com/article/Samsung-830-Series-256-GB-SSD- Review/1631/7 ---------- Original message ---------- Subject: Re: SSD?

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… > 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. 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… > For heavy use, I > would still think OWC. 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! Cheers, Andreas aka Mac User #330250 p.s. > Just from prior research I've done > when considering buying a used cube for fun... 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… -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
