其實而家差唔多所有Seagate Backup Plus 2.5" 都係SMR, 但會行Hybrid Mode,
即是好似 TLC SSD 開 SLC Cache咁, 會有PMR 同SMR Track, 所以寫入速度會拍得住 PMR 碟
但耐用度就唔會及得 PMR 碟啦

綜合兩個POST 即係死雞可以遠離.
2.5 2TB 以上全部SMR.
3.5 8TB USB Archive model SMR.

WD 唔大過12TB 都不用擔心. 可以放心使用

死雞連2TB 都係SMR, 因為成年前以經係轉左用 7mm 2.5" HDD
WD 4TB 好似都係SMR, 因為之前2.5 用 PMR 最叻嘅係三叔做到單碟 667GB,
而WD 4TB 應係 15mm 5碟x800GB

As far as I know, no matter which brand, all 2.5" portable hdds at 4tb or above ... they are SMR

As I need a 4tb portable for backup purpose, got no choice, still bought the seagate backup plus.

If 3tb is ok, I would go for adata

Yes, the read/write speed is ok

Regarding durability, we just dunno yet.  Anyway, Seagate Backup Plus 2.5" has 3 years of warranty.
