其實只是吃飽閒閒剛好看到對面B站關注的UP主剛好更新了相關的影片
https://www.bilibili.com/video/BV19f4y1U76J
(簡體字PTSD者勿入)
以下是影片重點:
一開始跑HDtune
SN750 1T 全碟寫入穩1.6 GB/s
SN550 1T 全碟寫入穩87x MB/s
因為懷疑WD有沒有對HDtune做優化
作者用了極度暴力的總計885GB的"正當防衛"壓縮包進行大容量壓力測試
SN750 1TB
剛開始寫入在1.5 GB/s浮動
中間全程在1.6 GB/s浮動(論暖身重要性)
最後快結束回到1.5GB/s抖動
最終溫度達到71~73度(無散熱片)
SN550 1TB
全程穩定835 MB/s
溫度57度(無散熱片)
作者還不信用手去摸XD
結論就是WD大概也拿到了外星科技了吧(誤
以下個人優缺點總結都是針對1TB版本
(目前市面上大部份都是1TB性能最強 2TB或更小容量反而性能衰退)
優點:
1. 保證原廠快閃記憶體(WD旗下SanDisk)
不用擔心不同批換料(某自家嚴選顆粒/美光/紫光抽抽樂)
2. 五年保
3. SN750效能不錯 溫度也不錯(需散熱片) 價格也比三星便宜不少
4. SN550效能不差 溫度低 價格便宜 同價位性能優於SATA和PCIE QLC渣渣
缺點:
1. SN750其實也不便宜 差不多要台幣5k多
2. SN550無DRAM 有些人會介意
打這麼多其實只是想騙點P幣
沒有拿到WD半毛錢
只有自費裝了SN750 1T和SN550 1T體驗玩遊戲時心靈速度感的提升
(X570通道多就是能為所欲為 能裝兩條滿效能的PCIE SSD)
上次版上吹了一波SN550
某屋SN550 500G有一陣子賣到缺貨XD
看看過陣子SN550會不會和MX500平起平坐吧~
