Either is fine but use western digital purples.
But if you purchase with us we do offer the warranty and it comes installed.
i'll be calling or email you to place order.
if i install a drive(s) does the DVR still have a warranty but not the drives?
comparing drive prices today.
i see seagate is shipping 8TB drives for 260.0usd. they aren't the western digital "NAS purple" types though. a "WD 4TB purple" can be had for 186.0usd
thanks for the help, talk with you tomorrow
