根據個人用了十餘組NAS的經驗: 1.如果是工作群組在用的NAS,或者是使用頻繁的NAS,或者是有組建RAID的NAS的話,使用NAS專用硬碟要好的多。用普通硬碟的話就算不故障也常會發生RAID軟失敗(要把硬碟拉出再插回重建)。 2.如果你的硬碟是半冷儲存(放大量影片或A片,沒有太重要),存取率低,也不組建RAID的話,用便宜的普通硬碟就行了。畢竟一個 Bay 也挺貴的,硬碟四年左右就可以拉掉換更大容量的替換版本了。
SSD (solid state drive) is way to go. NAS is still HDD that has moving part inside. although higher in price, SSD is much more reliable, making it a more cost-effective storage device. SSD has much higher reading / writing access speed too.
