I'm going to run Windows 7, and I want to have room for some games, Office, Photoshop, etc. I think a 128GB drive would probably work OK, but it would definitely be nice to have some extra space. I have heard that Samsung's drives are more reliable than the Sandforce-based OCZs, but with the Agility having 2 times the capacity of the Samsung for only ~90 bucks more, it's very tempting. I know that the Samsung is supposed to be faster with sequential read/write stuff, but I don't know how much of a difference that would make in real-world usage. I also know that 256GB-class drives are typically faster than 128GB-class drives anyway, so...
I am using an Intel 120gb SSD. With windows 7 64 bit, 6-8 games, and 4gb of photos, I am using 85gb.
My plan was to wait until I filled it up before doing anything, feeling that SSD prices will drop . So far, It has lasted longer than I thought.
I don't know if I will get a second SSD for overflow, get a second 510 120gb for raid-0, or put the old in a laptop, and get whatever is new.
I am using the 510 series, but I can not tell the difference in performance compared th the earlier gen2 X25-M 80gb drive.
In random access, and low queue rates, all SSD's perform similarly. That is what the os does mostly. Today, I am not planning to chase high synthetic benchmarks.
The Samsung 830 is the successor to the wildly successful Samsung 470. The 470 has an absolutely stellar track record. There were no major issues or problems. So far it looks like the 830 is going to be just as good as the 470. Both ssd's are Samsung designs with their their own in-house controllers, flash, and components. It looks like Samsung got it right both times.
