Seagate supposedly has a hybrid hard drive in the works -- along with Samsung (for certain). All the remaining manufacturers will likely have hybrid magnetic platter / flash memory hard drives as well.
Actually, I was talking about SSD drives based solely on flash memory. Some of the architectural differences in flash-based SSDs could end up being drives based on:
1.) Pure premium speed NAND flash memory (expensive),
2.) A mix of premium grade NAND flash memory and slower "cheap" NAND flash memory with an intelligent storage controller using HSM (hierarchical storage management) techniques to keep performance optimal,
3.) A mix of premium grade NAND flash memory and premium grade (or slow "cheap") NOR flash memory with an intelligent storage controller using HSM (hierarchical storage management) techniques to keep performance optimal.
Once these flash-memory-based SSDs start coming out in volume, they will get dissected.
...resulting in a slightly MORE affordable SS drive. :smurf:
Yes Seagate & Samsung have announced intent to ship hybrid drives in time for Vista, with Samsung more bullish on the possibility of using up to 4GB of NAND.
Neither 2 or 3 are likely (particularly 3 since NOR is basically like the CRT, at the EOL stage as tech moves on).
Premium? Not in mass production. Mass production, like with faster CF cards for ever increasing MP digicam's increase over time, decrease in price over time. Same will happen for flash based computer drives, it's just a matter of when?
Performance of the PQI 32MB (as well as the 64GB I would guess) linked to above is not anywhere near DDR2 battery backup, RAM drives. But they aren't designed as such. These are laptop speed (well as fast as the fastest current 7.2k laptop) SDD, with attributes more than just speed that make for ideal use in laptops. Samsung is quoting 58/32 RW for STR.

Only test I've seen, which is quite incomplete, would be for the Samsung laptop, and PCWorld's test of the
32GB Samsung stating only STR figures. (Engadget has the rumored OEM quantity price on the 32GB @$900 in Asian markets).
Ah the debate continues on longivity, check out the comments in this link, lol:

Almost forgot, Tom's Hard, did a wider range comparison btw HDD & the new 32GB Samsung:

Personally, I'd rather take my chances with RAID0 SSD's, if I had the choice btw that and HDD's. If SSD's are using HDD storage structures, I wonder if that they leads to file structure corruption problems we have with HDD tech, or is this a function of moving parts in the HDD? Haven't seen any discussion of that yet.
