sasuke

自己睇路...
係咪又係時候要瘋狂搶舊版SSD...但Amazon Black Friday未到...點算

幾時到980pro同SN850 最高階呢兩款都開始換料???

重點:  the two revisions performed similarly in a real-world copy test with a 154GB video file. The old version has a smaller SLC cache, but a higher sustained write performance. Although the new version's SLC cache is 173% bigger, it offers 47% lower sustained write performance.

重點唔係

On hardware level, the original 970 Evo Plus employs Samsung's Phoenix controller (S4LR020) and 92-layer 3D TLC NAND flash with the K9DUGY8J5B-DCK0 identifier. The new 970 Evo Plus, on the other hand, utilizes the Elpis controller (S4LV003).

For those not familiar with Samsung SSDs, the Elpis controller is the one that powers Samsung's 980 Pro SSD. Although the Elpis controller is designed for the PCIe 4.0 x4 interface, it's also backwards compatible with the PCIe 3.0 x4 standard, which is why Samsung can recycle it for the 970 Evo Plus. Basically, the new 970 Evo Plus is like a 980 Pro, but without the PCIe 4.0 speeds.

我就覺得好多過壞

As per the result, the old version started at 1,750 MBps and eventually dropped down to 1,500 MBps after the 40GB mark. On the new version, the drive steadily performed at 2,500 MBps, but once the 115GB SLC cache was exhuasted, the SSD fell to 800 MBps. This represented a 47% performance hit.

舊版40GB 後跌速, 新版115GB後跌速
睇下自己有無咁多115GB file要抄?

    According to the YouTuber's findings, the new version with the Elpis controller runs warmer than the old version with the Phoenix controller.

速續+大size 舊好d
隨機4k 新好d
極限速度下 溫度 尖鋒 舊8x度  新9x度
idle下 舊5x度 新4x度 (無打錯，一般人pc 用相信新會好d，因為唔係長期尖鋒)

我覺得無需要特登買舊(甚至我想 將條2t 換新..... 不過都係等下pro/sn850 平再算 實在)

本來諗住買Transcend 220S 2TB ，咁都係等多陣買新版 970 EVO+ 好囉
