SSD vs. HDD

[LonezWolf1991]

Does anyone know if Lion enables TRIM for Non-Apple SSDs?

I wholeheartedly agree that SSDs are orders of magnitude faster than HDD's- I'm just not sure the performance gain on RAID 0 would be that big, if any, considering the differentiation is the elimination of seek time and thus the boosting of IOPS, not raw speed (although SSDs do well there too).

There isn't really a significant price advantage to multiple smaller ones, also, you're talking about big bucks when you're doing more than 200GB of SSD storage in the first place. I like the two drive system, as for now, it provides me with the speed I desire for relatively minimal cost and large storage. At the current prices, it would be downright wasteful to have a large iTunes library and photo collection on an SSD. VMs, the OS, and applications, however, benefit hugely from the SSD.

Yep - pretty much agree. Although when you look at SSD prices for 240GB, compared to 480GB - they seem way more expensive. At least to my research as of 7/24/11. I can buy two 240's for about $800 compared to one 480 at about $1,100 - so buying two actually saves you a bit - plus you get the speed benefit if using RAID 0.

I'm running a few VMs and the SSDs really shine here as well - like you mentioned. All in all its the best $800 I've ever spent on a computer upgrade.
