CHING請教你一下
點解channel少一半 write會差咁遠 但read又冇乜分別?
可以以vertex 2例子說明 我搵唔返 ...

點計寫入次數? 用一日 (8hr) 上網大慨用幾多"次數"?

這個問題你要問OCZ了，不過25nm的初版是界乎3k-5k P/E cycle，而且V3使用的是2Xnm NAND (可以是25nm也可 ...

OCZ在資料公佈方面一向都很閃縮

thx ching
不過我想問 因為channel的問題 而令新的變慢
為甚麼write會慢接近一倍 而read只是慢少少?

因為OCZ出貨量都不算少，亦由於NAND Flash價格每日的浮動很大(期貨市場...)，所以OCZ的Flash可以來自不同的供應商。所以OCZ先寫2Xnm，唔係寫28nm (因為如果用25nm的話就好像欺騙消費者)。

Currently OCZ ships drives with NAND from four different companies: Intel, Micron, Spectek and Hynix. The Intel and Micron stuff is available in both 34nm and 25nm flavors, Spectek is strictly 34nm and Hynix is 32nm.

Each NAND supplier has its own list of parts with their own list of specifications. While they're generally comparable in terms of reliability and performance, there is some variance not just on the NAND side but how controllers interact with the aforementioned NAND.

Approximately 90% of what OCZ ships in the Vertex 2 and 3 is using Intel or Micron NAND. Those two tend to be the most interchangeable as they physically come from the same plant. Intel/Micron have also been on the forefront of driving new process technologies so it makes sense to ship as much of that stuff as you can given the promise of lower costs.

如果你指SandForce controller的資料的話，我個人覺得SF比Intel公佈得更多。

多謝支持。

因為其實一直以來好多網友都擔心SSD壽命的問題，所以才想開post一次過回答。
