标题: [闲聊] 三星970EVO Plus换料和快取外速度砍半
时间: Wed Aug 25 18:10:04 2021
不清楚台湾有没有开始卖新版
这两天对岸也开始发现三星970 EVO PLUS偷改版(TLC PCIE 3.0x4)
主要以下几点
1. 换包装 原本是横版改直版
2. 韧体版本从2B开头变3B
3. SLC模拟快取从42G暴增至118G
4. 料号由MZVLB1T0HBLR改为MZVL21T0HBLU
5. 主控已无凤凰LOGO
6. 快取外速度由1.6GB/s砍至800MB/s
官网介绍也有人去爬记录档发现三星偷改
1. 原版强调用自家凤凰主控 新版则是暧昧的in-house(自有)主控
2. 原版有写出快取外速度 新版皆已移除 只有英文版有一小段漏网之鱼
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. 其他顺序/4k写入等数据介绍目前无更动

硬要说就是SLC快取加大
快取外速度砍半对普通使用者无感
只有搬运大量资料和跑分时才会有感
970EVO Plus新版影响不如SN550(快取太小)影响严重
只是业界领头羊也这样偷偷摸摸就很微妙了
