SSD idea

[Cerulean]

What if they made a performance, scratchdisk, and ramdisk SSD that contained a couple hundred or so 16/32/64/128MB chips in RAID0? I'm sure they could accomplish this if they use a small enough capacity for a small enough physical size per chip..

That would be very bad for writing since the block size would be too large. Also this would be extremely expensive. And a new controller would need to be made specifically for this.

A couple hundred chips in raid0...

Yeah that's not asking for failure or anything.

Yup, sounds like a terrible idea. Just buy more RAM, create RAMDisk.

The Intel SSDs have 10 parallel flash channels, meaning it is like a RAID0 of 10 SSDs. This can be seen nicely in benchmarks like AS SSD; where the random read QD64 is ~8-10 times higher than the qd=1, which can only use one channel at a time.

You mean like Intel's Turbo Memory from 2005?

No the X25-M 80GB and 160GB; theX25-V has 5 flash channels.

I'd imagine there will be a scaling problem, rather than reliability.

Sure speeds will be faster, but the controller has to work that much harder erasing, writing a new block, writing error correction code, checking that the write was successful. That's just a single write.
