there is bottleneck with this HDD


11 months ago.

Good bang for buck. Suit Linux desktops or as part of a storage group. Will be the weak point for Windows 10 updates and other heavy laods on even the oldest hardware. Could do with a GiB of Cache. Entry level SSD is 9 times the cost. Much less noise than Velociraptors, just be aware these can be a bottleneck on Windows.
