Fast Hard Drive?
- Thread starter gnome

Depends what you are doing with them, the read times are fast and the access times blow away any mechanical hard drives.Quote from gnome:
They're expensive and none faster... probably slower because of the flash overhead like USB drives.
If you want to compare performance aspects of different drives why don't you just go to StorageReview.com?

You sure those benches apply in the real world? Whenever I copy folders of data from hard drive to a USB flash drive, it's lots slower than copying to another hard drive or even a different folder on the same drive. And SSDs are just bigger flash drives.
Quote from Sparohok:
Flash totally owns hard drives in every way except price, and even that's "... changing fast.
USB flash drives aren't designed for performance. For one thing, USB is dog slow. A purpose built flash drive on a proper IO bus is a totally different animal.

In spite of your conviction for SSD, I've yet to read a review which claims they are as fast as magnetic drives... but I'll keep an open ear. The below is from a Wiki page about advantages and disadvantage of SSDs....
"... Limited write cycles. Typical Flash storage will typically wear out after 100,000-300,000 write cycles, while high endurance Flash storage is often marketed with endurance of 1-5 million write cycles (many log files, file allocation tables, and other commonly used parts of the file system exceed this over the lifetime of a computer). Special file systems or firmware designs can mitigate this problem by spreading writes over the entire device, rather than rewriting files in place. [3]
"...Slow random write speeds - as erase blocks on SSDs generally are quite large, they're far slower than conventional disks for random writes [4]..."
And from a Cybernet article...
"... Here are some of the things that may not be so lovable about solid state drives.
* Price - Currently around $25 per GB compared to about $0.25 per GB for mechanical drives.
* Slower write time - Around 18 MB/s compared to over 50 MB/s for hard drives.
* Lower recoverability - After an SSD fails it is nearly impossible to recover any of the data.
* Vulnerable - An abrupt powerloss, magnetic fields and electric/static charges could have more of an effect on an SSD compared to normal HDDâs.
Something to remember about Raptors (if you care) is that they are noisy little suckers compared with slower drives.

Samsung Reveals High-performance 64 GB SATA II SSDs
Monday, 05 November 2007
The 64GB SATA II SSD is based on Samsungâs cutting-edge NAND technology with dramatically improved performance specs that are taking system performance to a whole new level of efficiency,â stated Jim Elliot, who is the director of marketing for the NAND flash Department of Samsung Semiconductor inc.
Samsung has unveiled a Solid State Drive aimed at high-end PC and server storage markets. Up until now, the SSD options available to the average person were mostly for the mobile market. This is due to the enormous power saving advantages of not having moving parts. SSDs typically use a third as much power as their physical motion counterparts, which saves battery power while performing about the same. These new drives use slightly more power than its predecessors (0.7 W vs 0.4 w), but perform up to five times as fast as normal 1.8" HDDs.
As with each previous incarnation from the NAND flash leaders, the new 64 GB drive has improved greatly in almost all areas. The new technology has some amazing specifications that will give any techie butterflies. With sequential write speeds of 100 MBps and read speeds of 120 MBps, these new drives blow away the fastest consumer grade devices of today. The rest of PATA/SATA market sustains approximately 50-80 MBps read/write rates.
