- #42 [呀金], 21-02-22 22:15呢個係技術性問題,跟製程同設計亦有關係,容量越高代表每個cell越細越密/阻隔層越薄,漏電機會越大。這也跟半導體廠商的技術亦有關係。

- #39 [呀金], 21-02-22 17:06Flash 利用電荷儲存在cell內來分別0同1,但電荷會慢慢流失,需要通電好讓內部firmware進行refresh補充電荷至高水平。
長期不通電會令電荷流失,到了一個低水平之後,就算再通電,firmware也無辦法判斷之前儲存的是0還是1,咁data就永遠失去。 - #38 [kennycwc], 21-02-22 13:30ssd 太耐無通電會乜都無哂.......>>>

The level of charge in each cell must be kept within certain thresholds to maintain data integrity. Unfortunately, charge leaks from flash cells over time, and if too much charge is lost then the data stored will also be lost.
During normal operation, the flash drive firmware routinely refreshes the cells to restore lost charge. However, when the flash is not powered the state of charge will naturally degrade with time. The rate of charge loss, and sensitivity of the flash to that loss, is impacted by the flash structure, amount of flash wear (number of P/E cycles performed on the cell), and the storage temperature. Flash Cell Endurance specifications usually assume a minimum data retention duration of 12 months at the end of drive life.
For other durations, a Storage Time Factor (STF) can be used to adjust the Drive Endurance equation. The STF is measured as a ratio of time as compared to the standard 12 months. For example, if a 36-month storage duration is desired the STF would be 3 (36 months / 12 months). - #36 [明天的明天], 21-02-22 12:30ssd 太耐無通電會乜都無哂.................但USB手指太耐唔搵佢, 又係會唔見左...................................
- #35 [呀金], 21-02-22 12:24USB手指同SSD入面都係用同類memory chip,係controller 不同。
手指用於external,SSD主要用在internal。

邊種穩陣啲?

呢兩日執屋,有4隻IDE HDD,三隻80G 一隻30G。 - #32 [BB1668], 21-02-22 11:26部老爺叉陸零仲行緊隻20G硬喋!
- #31 [Lilaclee], 21-02-22 09:42#30,
17G,放4套AV都可以 - #30 [lym], 21-02-22 09:22古物

online大量高清backup,應該係其它絕版珍藏! - #27 [呀金], 21-02-13 16:20三上xx mp4檔案,網友可能有backup,可以大家share番,唔算太珍貴。
- #26 [vxair], 21-02-13 16:14>>>>>>有啲嘢真係好珍貴好有紀念價值
唔通係三上xx mp4檔案? Kakakka - #25 [呀金], 21-02-13 15:51Krell 兄,
無辦法啦,有啲嘢真係好珍貴好有紀念價值,有錢都買唔番。三隻ext HDD 有限錢,分分鍾平過一部手機,計落其實好值得的。 - #24 [kenhks], 21-02-13 15:45過年前啱啱買咗1TB SSD
- #23 [ich], 21-02-13 15:33#22
重要文件有三個 offlinebackups係正常.再好D加埋雲端及其中一個physical backup放在另一地方.
