Hello guys-i want to say that this hard disk is currently is in use by me in my beast pc , I have 2tb version of this , this hard dist is faster than , normal wd blue hard disk because it is used in CCTV cameras hub, this hard disk have capibility of running for years , without stopping it because as I said it is used for CCTV camera. Storage hubs , its read and write speed is a lot faster than normal hard disks, but it is a bit more expensive than WD blue , and you can easily trust this company because this is one of the best companies for storage solutions. I also use its external hard drive for on the go use. Thanx guys have a nice day , iam also attaching some pics must see.
