西数发布SN350绿盘SSD：寿命令人绝望

日前，西部数据发布SN350系列绿盘SSD。

既然是绿盘，肯定主打低价，这批M.2 2280固态盘容量分别是240GB、480GB和960GB，定价43.99美元（约合283元）、54.99美元和99.99美元。

价格倒是不贵，但官方并未给出颗粒详情，只是从写入寿命判断，大概率是QLC。960GB的总写入字节数80TBW，480GB总写入字节数60TBW，240GB总写入字节数为40TBW，参考3年质保时间，960GB的每日全盘写入次数居然还不到0.1次……

性能方面，因为走的是PCIe 3.0 x4通道，最高连续读取为2400MB/s、最大连续写入为1900MB/s，随机读速最高340K IOPS，随机写速最高380K IOPS。

考虑到蓝盘SSD 250GB的写入寿命就高达150TBW，预算足够的话，绿盘SSD还是三思入手。
