三星此次發佈的 SSD 有兩個系列
840 Pro 主打高性能市場，使用的是 21nm Toogle MLC 快閃記憶體，容量最大 512 GB
840 系列主打主流市場，容量最大為 500GB
但是卻是用 21nm Toggle 2.0 TLC 快閃記憶體，這在 SSD 廠商中算是比少見的情況
TLC 快閃記憶體目前大都用在隨身碟上，用在 SSD 的上並不多
TLC 與 SLC、MLC 相比每 cell 單元可以儲存 3 位元資料，這樣一來容量會大大增加
但是寫入速度、可靠性也會下降
價格方面，840 Pro 系列的 64GB 為 99.99 美元
128GB 為 149.99 美元，256GB 為 269.99 美元，512GB 為 599.99 美元
840 系列相對來說便宜一些，容量從 120GB 起跳，售價為 109.99 美元
250GB 為 199.99 美元，500GB 為 449.99 美元
三星 840 和 840 Pro 系列將在 10 月 15 日正式發售
