Sorry John, I think you're mistaken there. On a raid card solid series performs almost like core, cache is integrated in raid card, on-disk cache makes zero difference. Only difference is the theoretical 20-30mb/s for peak bandwidth (they're rated 200 vs 170 or something).

Edit it's 230 vs 170, sorry 'bout that, but still these are theory numbers. I can get my 4x170 no prob when benching with the raid card, but in PCM05 I get about 80 To be clear I have a core V2, not a solid.

core, solid, all the same JMicron which fails at 4k random write; PCMark05 XP startup IS random read/write; Indilinx controller with latest OCZ firmware on the Vertex is massively better than JMicron SSDs;

got any data to back up your claim? theoretical bandwidth means nothing, PCMark05 HDD is all about random mixed read/write IO; raw sequential speeds tell us nothing hence the specs don't matter;

RAW data, random 4k write:
- X25-M 23mb/s
- Vertex 6.47mb/s
- JMicron Core/Solid V1/V2: 0.02mb/s

Vertex is 323x times faster than Core/Solid SSD, Intel X25-M is 1150x times faster

that's because XP startup is a random read/write 4k benchmark, where JMicron drives suck compared to Vertex/Intel

SINGLE vertex PCM05: 78mb/s http://hwbot.org/result.do?resultId=836355
imagine 4 of them in RAID 0

so u say that intel's one is best for the benching part ?

X25-E is faster still SLC vs MLC;
but are we looking at price or not?

fastest is Software RAM DISK if you must now; but impossible at this time to load OS on there... maybe in the future
6000mb/s read speeds

yes and then the vertex wins by miles .

These numbers mean nothing when you don't test with a raid card. Everyone knows that jmicron is a culprit when used standalone. There have been ZERO reports of stuttering when the solid/core drives are used with a hardware raid controller WITH CACHE.

please quote me where I talk about stuttering?
single vertex reaches 80~100mb/s in XP startup test
two in raid double of that, 4x of them in RAID without MFT who knows
cache can only help so much...

anyway, for benching, to answer Blind's answer: most affordable and fastest is ACARD (€350) with 4~8gb DDR2 (€80~120). Buying a RAID card (€350) and 3~4x 30gb Vertex will be more expensive, not necessarily faster.

I don't dispute this, but have you already forgotten about Massman's troubles with single/double Core V2's in PC05 ? There wasn't any scaling at all... this has nothing to do with 4k random read/write, but is a SSD scaling problem in PC05.

he didn't use a dedicated PCIe card
