$26,980,SN700 4TB 價格則是 $23,990。不過這 10 條大約就是 24 萬了,遠超過 NAS 本體的價格。 <figure style="clear:both;"> <div role="button" tabindex="0"> <div style="margin-left:auto;"><picture><source sizes="(min-resolution:

OS:Microsoft Windows 11 22H2 在 CrystalDiskMark 中,設定測試為五次 4GiB。最佳效能的設定下,循序讀取速度超過 3,395MB/s,與標示差不多。循序寫入 3,106MB/s,也與標示相當。混合讀寫速度能到 2,679MB/s,相當不錯。 接著在 CrystalDiskMark 中,同樣設定測試為五次 4GiB,改為在真實世界的設定。循序讀取速度略為下降到 2,565MB/s,循序寫入速度則維持在 3,000MB/s 以上,混合讀寫速度為 1,749MB/s。比較意外的是在這項測試中,讀取速度略比寫入低一些。 在 ATTO Disk Benchmark 中,在 16KB 以上寫入速度都在 2.88GB/s 以上,讀取在 256KB 以上也都在 3.00GB/s 以上。在小的 I/O Size 上,相較一般消費級的 PCIe Gen3 x4 SSD 來說高出非常多,甚至在這個區間的寫入,表現還比讀取優異。 在 PCMark 10 當中,在 Full System Drive Benchmark 得到 1,809。 在 AIDA64 Disk Benchmark 中的 Linear Read,Block Size 設為 8MB。速度表現非常穩定,都在 2,700MB/s 以上,非常平穩。全碟讀取平均值為 2,809MB/s,容量為 3,726.0GB。 在 AIDA64 Disk Benchmark 中的 Linear Write,Block Size 設為 8MB。前面 4% 一小段,換算約 150GB,寫入速度能在 2,300MB/s 以上。接著掉到 2,000MB/s 左右,一路平穩到結束。在 TLC 顆粒的產品來說算是相當好的,到後期沒有因為 Cache 用盡而明顯掉速。也因此寫入速度平均值達到 2,014.0MB/s 的好成績,甚至與許多 PCIe Gen4 x4 TLC NAND Flash 的 SSD 差不多。 WD Red SN700 4TB 的確比目前 PCIe Gen3 x4 的消費級 4TB SSD 還要貴上三、四倍。除了從規格表上可以看到官方標示的耐寫壽命較大多 TLC SSD 還要高數倍,從 AIDA64 的全碟寫入也可以看到,其寫入速度雖然不是頂著 3,000MB/s 跑,但可以讓全碟維持在 2,000MB/s 以上一路到底。這點也相當不容易,基本上 QLC SSD 都無法達到這個等級,TLC SSD 很多也做不到。不虧是主打 NAS 使用的 SSD,在這方面的表現著實出色。
手上總共 10 條 WD Red SN700 4TB,其中 8 條搭配 ASUSTOR FS6712X,共 32TB 容量,建立一套 All Flash NAS。
