插落部腦度等好耐先load到出嚟， 抄啲電影檔落去播放嗰陣時 窒下窒下。 行曬磁碟重組修復 都係冇乜改善是否隻hard disk就嚟壞

SMR碟係咁

SMR碟係咁, 唔可以重組
佢窒既話, 你應該插住佢唔用, 由佢自己整理下
越write野落去會越窒, 甚至freeze

Trim下佢唔好disconnect等佢自己重組

你USB Mass Storage而非UASP Mode都得?

I have a Seagate 2.5" 4TB (ST4000LM024-2AN17V), a non-stop write of 3TB of data without "窒下窒下", very smooth. Suggest to quick format your hdd, then re-copy several video files (very large ones) to test it again.
I've been using that 4TB SMR for daily backup (with add/change/delete operations) for nearly 3 years. Read/write speed reduces (from 11XMB/s to 6XMB/s) as time goes by. I would perform a quick format once every 4 months to refresh the hdd to like new (11xMB/s) performance. Of course, it needs more than 24 hours to re-copy everything again (redo a full backup).
IMO, the effect of quick format is much better than those so-called disk optimisation/trim operations.

SATA 新Version 已經加左SMR HDD（當然HDD都要支持呢個新協定）可以用TRIM Free返D位出來，drfgui 用reTRIM通知HDD主動回收空位
原來已經出左

你第二段內容肯定是誤導人，使用TRIM和reTRIM 通知隻HDD主動回收空間, 就等如SSD Garbage Collection
舊版SMR抄爆碟，速度回不過來。
新SMR 只由其它HDD抄data過來，跟本可以不用defrag，不過。。。前提是不要要裝得太滿隻HDD （視乎裝什麼大小FILES)

I think my 4TB 2.5" SMR was the so-called "舊版". It doesn't support trim command, I suppose. And I've no idea about those "新版" SMR.
The 2nd paragraph was the actual user experience (3 years of use, no kidding).
1. Day one, read/write speed was 11x/11x MB/s
2. After months of use (with plenty of add/change/delete operations and hdd was nearly full), read/write speed reduced to 6x/6x MB/s
3. quick format the hdd, read/write speed was back to 11x/11x MB/s
4. redo full backup (more than 3TB of data)
I've performed the above steps for more than 10 times during the past 3 years.
Regarding the point "舊版SMR抄爆碟，速度回不過來", it seems it doesn't apply to my case. And the "quick format" would always resurrect the hdd.

一次過寫入一大堆data係冇問題既
前提係真係純加data
而唔係不停又delete又加
否則速度跌落單位數MB/sec
quick format其實已經足夠還原SMR HDD速度, 唔使理TRIM唔TRIM
TRIM只係用黎改善平時delete file既處理, 減少越用越慢既情況

Yes! As mentioned, I've been using 'quick format' to refresh the hdd for years. As my old version SMR doesn't support TRIM, 'quick format' is the only way to resolve SMR drawback.
Someone mentioned "誤導", may be someone doesn't know that 'quick format' can refresh SMR hdd

1TB 2TB 呢啲細容量 HDD 無錢賺
遲早全部細容量嘅硬碟都係 SMR
無得避

If SMR is a matter of concern, we could go for 1TB/2TB SSD (price drops gradually, it should be more affordable as time goes by). For large capacity storage, I think HDD is still the king.

發現時未死得哂,仲可以讀寫,去買左隻新既返黎諗住BACKUP,點知巳經copy唔到file出黎,
買過4,5隻死雞外置一直都無事,點知一死就死最新買果隻,好彩未過保養
