The 64MB cache keeps the hard drive running smoothly when activity is high. The trade-offs as you go higher in storage capacity are not worth it as of 2013. For example, the 3TB drives typically have slower access time than this drive.
As critical as I can be at times, it is difficult to knock this hard drive. Nothing negative to report here.
Do not buy just for storage capacity alone. Always think of the speed of performance (access time, transfer rates, etc.). If they made a similar drive with more than 64MB cache I may have bought it instead.
