Playing the price drop game is a never ending one. Instead, look for sales events during special sales (New Year, Easter, Christmas, etc.) - here we look for Black Friday (day after Thanksgiving) deals; always superb deals!
With the current price drops and rebates offered, I think now is a good time to buy. Don't use RAID 0 for any type of long term storage as one failed drive will lose all of your data. RAID 0 is best for high-speed temporary storage, such as video editing.
hmm should i get an 80gig RevoDrive (1st gen) instead? It's $254, i would use it as my boot drive. would i get a performance increase compared to the Vertex 2 if i mostly need it for processing data in Excel.
If you are interested in a raid array and faster speeds, then you may want to consider PCI-e based ssd's instead. The PCI-e based ssd's are available with multiple ssd's in a raid 0 array one on card. The drives fit in either a PCI-e x16, x8, or x4 slot on a motherboard.
There is one more thing I should mention. There are some motherboards that have only two PCI-e x16 slots but no x8 or x4 slots. The PCI-e x16 slots are backward compatible with x8 and x4 devices. As long as you only use the primary x16 slot it has all 16 lanes available for the primary slot. That primary slot is usually for a video card. However, if you add a second device such as a video card for Crossfire or SLI or a video card and a ssd, then both x16 slots are reduced to only 8 lanes each. Both slots have to share 16 lanes. The video cards will suffer a slight performance hit of about 2% to 5%. There may also be motherboards with more than two PCI-e x16 slots that also reduce the number of lanes available from 16 to 8 if mutiple devices are used. Please check your motherboard manual or manufacturer's web site for more information about your specific motherboard. Hopefully you'll have all 16 lanes available in all the PCI-e x16 slots.
*** NOTE - I looked at your motherboard specifications. You're in luck. A PCI-e based ssd with multiple drives in Raid 0 wil definitely work providing either your secondary PCI-e x16_2 slot or your PCI-e x8 slot is free.
We should see the release of new ssd's with improved performance between now and May. The prices of older models should be dropping. The new drives would still command a premium price. I've looked at industry forecasts. I don't expect a drastic drop in prices of new drives until the year 2015.
Your original question was about purchasing an OCZ Vertex 2 ssd.
I was just over at the OCZ web site and forums. OCZ changed from 34nm to 25nm NAND in their Vertex 2 series ssd's without any sort of press release or major announcements. In addition OCZ did not change the model name, product number, or description to reflect the switch. The Vertex 2 is still SATA II (3 Gb/s) too. Seems the 25nm NAND drives are not performing to customer expectations. I got the impression the new 25nm Vertex 2 performed worse than the original 34nm Vertex 2. OCZ may have been first to market with ssd's using 25nm NAND but that's all they can claim.
Intel on the other hand has simply delayed introducing ssd's with the new 25nm NAND. They are still working on manufacturing production quality 25nm NAND. The new Intel 510 series that will be introduced later this month will use the 34nm NAND. Looks like Intel is playing it safe and sticking with reliable components for the time being.
