參考一下 Anandtech 的測試

我直接節錄此篇文章中關於 C300 vs M4 的描述，其實最早M4剛上市就被發現了：
"The C300 is nothing new, we reviewed this drive last year. I still don't have a 128GB version of the updated m4, however as we discovered in our review of the 256GB m4, performance isn't necessarily better than the C300. In many cases the m4 is actually slower than the C300."
事實上 2011 年新一代 SSD 真正比起自家 SSD 上一代更快得只有以 OCZ Vertex3 為代表的 Sandforce 2200 家族 .......Intel, Crucial 自家新一代產品並沒比上一代產品明顯變快，但新一代產品過段時間良率拉起來會變便宜
