Meaning I have to benchmark the vertex in order to know if it's 25nm or 34nm?

The benchmark score seems similar with this... http://www.ocztechnologyforum.com/forum/sh...life-operationsDid you clean install the Windows ? Installed Intel Rapid Storage? What's the transfer rate when you copy big file ? |

Installed Intel Rapid Storage? What's the transfer rate when you copy big file ? Yes Yes 27~28 mb/second for 7.84gb file Ok. I've found out that FW 1.28 = 25nm chip. Maybe that's the cause of the slow rate  This post has been edited by XiuKeong: Feb 16 2011, 03:50 AM |

Is that speed by using USB 2.0 ?
What if transfer inside the SSD ?
Try the ATTO benchmark ?

Ah, missed the atto link...
Yours is the 25nm, then ?

Haven't done much research on F60..
Usually its the Intel X25-M G2 or the old Vertex 2...
Kingston V series eat more power than hdd...
How much the storage recognized from 60GB ?

Since most of my read/write is on the stock HDD from my laptop. This post has been edited by XiuKeong: Feb 16 2011, 04:12 AM |

Seems like 6GB is reserved...
You install both drive to your Acer and take out the optical drive ?

I guess its this issue.. QUOTE Drives are now shipping with 25nm NAND. This is the next die shrink the industry has been preparing to move to. One effect of the die shrink is the traces being closer together. Because of this the NAND is not as robust as the previous generation in regards to the voltage needed for writes and erases. This made necessary a reduction in the rated P/E cycles. The most common P/E cycle rating being 3000 now instead of the previous 5000.
To still provide a drive with a reasonable life expectation the amount of NAND set aside for over-provisioning has been increased by a few GB. So, for instance on a 120GB drive, if you see an unformatted capacity of 115GB this is perfectly normal.
Any questions concerning the move to 25NM NAND as it relates to drive size should be asked in this thread. Any new threads started related to this will be closed with a link posted to this thread. Also, please remember this is the support section of the forum. If you have a suggestion or complaint about the use of 25nm NAND use the appropriate section of the forum for those posts. Any post of a non-technical nature in this thread will be removed. Thanks. http://www.guru3d.com/news/ocz-vertex-2-wi...eported-slower/ |

XiuKeong have SSD now.   By the way, I'm wondering, Kingston ValueRams: PC3-8500 DDR3-1066MHZ SODIMM KVR1066D3S7/2G= PC3-10600 DDR3-1333MHZ SODIMM KVR1333D3S9/2G= Is there any difference? Oh yeah, XiuKeong, How's your SSD? Fast as hell? Darn yummy.  |

No difference, 1333Mhz will downclock to 1066Mhz since that is the one supported by your CPU..
Unless the 1333Mhz is the same price with 1066Mhz one, no need to pay extra for 1333Mhz...
