Still, 20k RPM is insanely fast. Ridiculously over priced when the final production is done? | | | Distinguished Member with 12,058 posts. | | Join Date: Apr 2007 Location: England, UK :) Experience: Advanced | | If we use that... do you think we might dont need RAM |  | Distinguished Member with 9,749 posts. | | Join Date: Apr 2006 Location: Pittsburgh, PA Experience: Mac Addict | | About time they start speeding up hard drives rather than just making them bigger.

| You can't be serious, SSDs have a long way to come. They cost upwards of 20 times hard drives for their minuscule storage capacities and have limited write cycles. Not to mention you could build a RAID array that's faster and larger an SSD drive for less money.

I'm not sure about that one. SSDs are pretty darn fast, and I'm not sure even a well-maintained RAID5 or 10 could match those read speeds. What's especially hot is SSD RAID arrays. Talk about fast!
Even so, you're right -- SSDs are crazy expensive for a little bit of space. But, I think that will change, and change quickly as manufacturing over the next year. |  | Moderator with 90,153 posts. | | Join Date: Oct 2002 Location: South Eastern PA, USA Experience: Advanced age & experience | | They still need to address the limited write cycles, I can see this being an issue in the coming days.  Writing to the FAT or MFT continually for a disk being updated all the time can probably quickly count up to the maximum write cycles for FLASH memory. | | | Distinguished Member with 9,749 posts. | | Join Date: Apr 2006 Location: Pittsburgh, PA Experience: Mac Addict | | Quote:

#10 | Another achille's heel i could see with SSD devices is that when they die, they die. Meaning that if sectors start to go and the device fails, there are no recovery tools to try to pick off what you can from that drive. That evolution will give new meaning to the word "backup". Although if they can do what JohnWill has stated and solve the write cycle problem, i do not think those things will ever die as it eliminates mechanical parts.

#11 | All of the designs use "wear leveling" logic to avoid continual writing to one spot on the disk. However, until these units get some running time under their belt, I'll remain cautious |  THIS THREAD HAS EXPIRED.
