   我覺得唔好係硬碟讀寫緊時侯玩震機就應該好長命，致於BT/斷電，暫時沒絕對證明，會快Ｄ ＫＯ 或者長命Ｄ

UNITEK Y-3355 does not support most of the smart tools out there!  The only smart tool that works (so far) is the one from https://www.hdsentinel.com/.  Even so, features related to idle timeout were not supported.

幾部NAS 用過幾十隻左右既harddisk, NAS 係行7x 24, 結果係隻隻唔一樣, 有啲用足6-8年都冇未死, 有啲死完RMA換一排再死, 所以係唔係長行就唔死.

結論都係長開少開都冇保證, 唔好晒精神, 索性backup多一兩份就最實際

My 3355 was local hong good (warranty provided by 升科國際 http://www.centuryfield.com/) and it has been running at 24/7 for more than 3 years, very stable.  

Regarding your "抄file一陣會自己斷線, 但好快又connect ...", I had an ICYDOCK 2-bay enclosure (ICYRaid MB662U3-2S R1) suffering exactly the same problem.  After checking this and that, I have returned it to local agent.  It was mostly likely chipset issue.

Is your 3355 local hong good or taobao stock?  Assuming your USB 3 port, cable and power supply are normal (usually), I suspect there is something wrong with the chipset of your batch

Tried the latest version of smartctl. Y-3355 accepts the timeout command without error (it needs an extra parameter -dsat).

-----> Command without -dsat :
smartctl -a /dev/pd4
or
smartctl -s standby,60 pd4

-----> Output :
smartctl 7.1 2019-12-30 r5022 [x86_64-w64-mingw32-w10-1909] (sf-7.1-1)

/dev/pd4: USB bridge [0x152d:0x0539] type is ambiguous: '[unsupported]' or 'sat'
Please specify device type with the -d option.

Use smartctl -h to get a usage summary


-----> command with -dsat :
smartctl -s standby,60 pd4 -dsat

-----> output :
smartctl 7.1 2019-12-30 r5022 [x86_64-w64-mingw32-w10-1909] (sf-7.1-1)

=== START OF ENABLE/DISABLE COMMANDS SECTION ===
Standby timer set to 60 (00:05:00 or vendor-specific)


Even the command works (it seems), it just won't spin down (意見接受, 態度照舊 ).  It keeps running and running and running.  Anyway, I like the way it is, never spin down.  I had a WD hard drive that spinned up and down many times a day for months, at the end the Load and Unload cycle count exceeded the threshold of 300,000

"Each time hard drive enters sleep mode and resumes normal working mode the head and hard drive's wear more rapidly."
