標題: [閒聊] 三星970EVO Plus換料和快取外速度砍半
時間: Wed Aug 25 18:10:04 2021
不清楚台灣有沒有開始賣新版
這兩天對岸也開始發現三星970 EVO PLUS偷改版(TLC PCIE 3.0x4)
主要以下幾點
1. 換包裝 原本是橫版改直版
2. 韌體版本從2B開頭變3B
3. SLC模擬快取從42G暴增至118G
4. 料號由MZVLB1T0HBLR改為MZVL21T0HBLU
5. 主控已無鳳凰LOGO
6. 快取外速度由1.6GB/s砍至800MB/s
官網介紹也有人去爬記錄檔發現三星偷改
1. 原版強調用自家鳳凰主控 新版則是曖昧的in-house(自有)主控
2. 原版有寫出快取外速度 新版皆已移除 只有英文版有一小段漏網之魚
Sequential and random write performance was measured with Intelligent
TurboWrite technology being activated. The sequential write performances for
the portion of data exceeding over Intelligent TurboWrite buffer size are:
400 MB/s for 250GB, 900 MB/s for 500GB, 1700 MB/s for 1TB and 1750 MB/s for
2TB. The random write performances for the portion of data exceeding over
Intelligent TurboWrite buffer size (tested with QD 32 Thread 4) are: 100,000
IOPS for 250GB, 200,000 IOPS for 500GB, 400,000 IOPS for 1TB and 420,000 IOPS
for 2TB. Performance may vary depending on SSD’s firmware, system hardware &
configuration and other factors.
3. 其他順序/4k寫入等數據介紹目前無更動

硬要說就是SLC快取加大
快取外速度砍半對普通使用者無感
只有搬運大量資料和跑分時才會有感
970EVO Plus新版影響不如SN550(快取太小)影響嚴重
只是業界領頭羊也這樣偷偷摸摸就很微妙了
