係咪淨係用Default個setting就行4k架喇?

WD 20EARS default is 4KB per sector, while 20EADS is still 512B.

the HDD is just made denser. all you're doing is picking the correct hardware setup for formatting that's all, it's not a choice for more/less space/performance

can i still get the same capacity if i use 512b formatting?

it wouldn't work.

basically it's like a computer asking you whether you put in a DVD or a CD to burn data, and you just pick the right one. picking the wrong'd only mean the whole thing doesn't work. there's no performance/memory/HDD space enhancement that can be done via formatting.

Formatting呢樣野係HDD生產果時已經定左, 唔到你揀
轉左4K Formatting最主要原因係降低生產成本

如果你當佢512Bytes Cluster黎用, align唔正, 會令效能不正常地差

如果你是使用 Windows Vista 或 Windows 7 來 Create Partition,那麼 Partition 就已經跟 4K Sector 吻合了。Windows XP 的 Partition 就跟 4K Sector 並不吻合,所以要執行 WD Align 令到 Partition 調整到跟 4K Sector 吻合。

將來的硬碟全部都會是 4K Sector,據我所知,2011 年開始其他硬碟廠商也會陸續推出 4K Sector 的硬碟,其中一個最重要的原因是因為目前 512 byte Sector 的硬碟的容量無法超越 2 TiB。所以,將來容量更大的硬碟就必定要用 4K Sector 了。現時 Western Digital 推出這些硬碟可能就是「試水」,大概也有著強迫那些 Partition 或 Clone Software 的軟件商修改它們的軟件和 4K Sector 兼容的意思。
