I was gonna buy a external hard drive but remembered I have 4 free USB's from a while back. They are 128gb each and do sequential 140MB/s read and 50MB/s write random is pretty bad at 10MB/s read and 5MB/s write but are probably still better than a harddrive. If put in 4 way raid 0 I'd presume I would get an at least 2x speed uplift but does anyone know of any issues I might run into doing this? I have watched some videos and people do have random freezes in game sometimes but in their case they had slow random writes on their particular USB (0.035MB/s random write from one video). Am I at higher risk of losing data vs a hard drive or ssd?
Would gaming on 4 USB's in raid 0 be fine?
No, get a cheap SATA SSD instead.
