奇亞幣挖礦熱潮不減,更多SSD製造商下修TBW寫入總量保固
https://www.techbang.com/posts/87436
幾個月前開始大熱的奇亞幣(Chia)挖礦熱潮,迅速推升了包括 SSD 和 HDD 在內的大容量儲存硬碟的價格。與此同時,短時間大量的資料寫入量,也讓硬碟製造商意識到現有的保固已經必須要修改,即便這麼做也讓許多普通消費者感到忿忿不平。
各家SSD的規格書裡,都會依各容量標註寫入總量(Total Bytes Written,TBW),也有廠商稱之為保證持久率。TBW值越大,表示固態硬碟(SSD)愈耐操寫,就可以活的愈久。舉例而言,一個 SSD 的TBW為500TB,消費者就知道,這個SSD在無法使用前,至少可寫入500TB的總資料量。
近日,有外媒對多家 SSD 製造商的保固條件進行了一番對比。結果發現,許多廠商都已經默默調低了 TBW 的數值,顯然是為了防止挖礦大戶們在普遍的五年保固期內,提前耗盡TBW然後反過來要求保固。
而對於一般正常使用這些 SSD 的消費者來說,基本上在一般使用的情況下,是不大可能達到廠商規定的 TBW 最大限制的。
比方說,以PNY(必恩威)為例,他們近日就在新政策中下調了 TBW 數值,以下就是外媒列出的比較表。
而 PNY 也在回覆 Tom's Hardware 詢問降低TBW值的原因,做出了回應。他們表示,主要基於兩個原因:首先,使用高速消費級 SSD 進行 Chia 挖礦的需求出現;其次,是整個產業目前正面臨著的 NAND 供應的短缺。
PNY 的新版質保政策已於 2021 年 5 月 17 日在官網公告,並且在 CS3030 系列 SSD 的規格表中標明。
先前,影馳科技(GALAX)也在官網上發布了一個警告資訊,表示如果消費者「濫用儲存產品」將耗盡此類硬體的寫入總量(TBW),進而導致售後拒絕保固。
綜合以上的說法,隨著以奇亞幣(Chia)為代表加密挖礦熱度持續增長,後續也許有更多 SSD 製造商選擇對自身更加有利的保固政策。
