![]() ![]() The power consumption while idling is around 4.04 W and in operation around 6.84 Watt for the 4 TB model, while we can see the largest power consumption for the 10 TB with 7.22 Watt during idling and 9.48 W at operation. Depending the capacity, the hard drives are having typical transfer speeds of 232 MB/s (the 4 TB model), up to 281 MB/s (the 18 TB model). Capacities of 4 TB up to 12 TB are coming with a 256 MB of buffer and the HDDs with capacities of 14 TB up to 18 TB are having a 512MB of buffer size. Then they have the 6 TB, 8 TB, 10 TB, 12 TB, 14 TB, 16 TB & 18 TB capacities. The 4 TB (the one we review) is the lowest one. Toshiba releases this hard drive in 8 different capacities. In fact, it is so high performing HDD that if Toshiba hadn’t announced that this is a NAS hard disk drive, we would thing that it is a desktop one. This amount of buffer memory along with the 7200 RPMs boosts the N300’s performance to the maximum. The hard drive we review has a massive 256MB of cache memory for buffering. The vibration compensation of the RV ensures high reliability and the longevity of the HDD. Toshiba has also attached to the drive various sensors that detect even the slightest shock and as such their advanced control and sensing technology in coordination with the built-in Rotational Vibration (RV) sensor, dampens all the vibration wear and tear on the HD. Just from that analogy, we can easily understand that the Toshiba 4TB N300 HDD is intended to be on the more professional grade category of HDDs.Īs a NAS hard drive it is optimized for reliability featuring a 1 million hours mean time between failures (MTBF) and it also has endurance with workloads of up to 180 TB per year in a 24/7 operation environment. The same can be seen with Western Digital where their Red Plus model is at 5400 RPMs but when you go for the WD Red Pro edition you get a 7200 RPMs HDD. An example is the Seagate Ironwolf that runs at 5900 RPMs unless you have the Ironwolf Pro model that runs at 7200 RPM. Strangely enough, as a NAS drive it has rotational speed of 7200 RPMs, something that you don’t usually see in the most common NAS HDDs unless they are the Pro versions. This drive is optimized by Toshiba for NAS use and it is certified for 24 hour x 7 days the week operation. ![]()
