版上的各位大大請教一個問題
小弟最近買進一只Patriot SSD 愛國者牌子的固態硬碟

還請各位大大指教該如何去判斷

16G SLC 報價14.80美金,16G MLC 報價3.85美金
市面上隨便一款16G SSD都是SLC FLASH報價的10倍...光看報價要怎麼估算?
同容量比較貴的就是SLC?
哎....
沒想到你連MByte跟Mbit都分不清阿.....
dram exchange上面寫的很清楚..
16Gb 2G*8 average $13 -> 這裡指的是16Gbit, 也就是我們常講的2GB(麻煩除以8好嗎?)
照這樣估計, 樓主買的32GB SSD, 若是SLC, 光Flash成本就要$13*16 = $208
RAID chip+Flash controller +SATA bridge+PCB+Housing 至少$40
這樣總成本約$248, 樓主以$300買入, 原廠加通路毛利只有20%, 這實在很難.....
我有找到另一網路購物賣相同的東西,網址如下:

不知道是什麼文,但它其中的規格中有寫到
POPIS 32GB Patriot Extreme Perform. SSD disk 2.5" SATA:
* Extreme Performance (EP) Solid State Disk (SSD)
* založený na flash pamětech (žádné pohyblivé části)
* ultra rychlý a odolný

* rozhraní SATA I/ II
* podpora RAID
* rozměry 100.2 x 69 x 9.5mm
* hmotnost 88g
* shock resistance 1500G/ 0.5ms
* napájení 5V

所以我在想買到的此SSD應該是SLC顆粒的,不知道對不對
還請不吝賜教,謝謝~~~
