想買USB手指 容量係64G  睇中SanDisk Ultra CZ48 or Ultra Fit CZ43

Extreme CZ80 is SSD. that is why it is super fast.

CZ80 is good, fast and stable, but exterior casing is pretty flimsy, you won't want to subject it to harsh conditions or rough use

Also note that CZ80 has separate USB2 and USB3 controllers and that the latter could fail if not treated carefully (as exemplified by early batches a few years back)

CZ80 好易死
我有個 （美版） 64gb
用3個月  
死左。完全認唔到

RMA翻個 （大陸版）
用四個月半死
Usb3.0 controller 壞左。  最多行到USB 2.1 mode 換三四部電腦都上唔到USB 3.0

唯一好處系RMA 幾方便

Sandisk Extreme CZ80 32GB owner here, bent the USB plug by accident, after that only work in USB 2.0 port.

Taken it apart to have a look inside, the USB 3.0 plug broken into 2 pieces, the two main soldering support were broken.

我之前隻 fit 64g 用了不夠6個月瓜咗，可能read / write data時太熱燒咗（因為fit比較短所以散熱全在chips之上），i⋯⋯

如果真係要快唔好買USB 手指了, 買隻256GB SSD + 2.5" to USB 3.0 case
Copy 平均有250MB - 300MB

之前仲浪費咁多錢來買64GB(4隻) 甚至 128GB(2隻) 手指, 而家256GB + Case 都平過, 又耐用過 D 128GB 手指。
手指的優勢係Size 細及細容量都係便宜

    case 用邊隻好？大摡幾錢？我都想買隻。

而家市面可以買既選擇唔多。

用過Transcend 銀色case (貴過$100 dd), Orico Case ($80-100)
Transcend 要上螺絲, 但涑度快10%左右。Orico 換 2.5" HDD / SSD 好方便, 唔好處係慢少少

Can't use TRIM under such circumstances
Once data is filled up, SSD performance will drop
Reformatting won't work until TRIM command is run (and that SSD need to be directly connected to SATA)

    what about those Sandisk SSD usb stick. these sticks have SSD controller, nand and USB 3.0 to SATA converter.

so they will drop speed as well?

SSD to USB有兩種。速度，穩定，價錢 (1) > (2a > 2b> 2c)
你自己上網check 價啦

1. M2 SATA type + NGFF to USB adapter， 呢種最貴，最快，最細size
eg. M6E, SM951(SATA)

2. SATA SSD + 2.5" HDD to USB adapter， SATA SSD主要以controller 來分穩定，效能
a. Marvell controller, Crucial MX200, Adata SP920, Plextor M6S
b. Silicon motion controller, Transcend 370, crucial BX100, PNY Optima SSD
c. Phison S8 controller, Silicon power s60
