My previous 6TB (WD60EFRX) hard drive failed in my DS718+ 2 hard drive NAS. After quite a bit of research, i found that this particular one was an acceptable replacement for the failed drive. I had no issues testing it, installing it, or using it and it has worked great. I've had it for about 1 month now. I have since ordered a 2nd one to have it available in case of abother hard drive failure. This one replaced a WD60EFRX- 68L0BN1
I would recommend this to a friend!
