Western Digital has announced a new 4 TB model in its range, the WD Black 4TB. Like all models in the Black series, the engine of this hard drive runs at 7200 rpm.
This is not the first 4TB model, but this is the first consumer model running at that speed. With an advertised price of $339, the price per GB is quite high compared to other models in the range. The WD4001FAEX– its name – has a SATA 6 Gbit/s interfaced and has 64 MB of cache. With a consumption of 10.4 W, the hard disk consumes a little more than the average, and it is obviously noisy: 29 dBA at idle and 34 dBA in operation. For comparison, a “Green” model is announced at 6 W and 24/29 dBA.
The speed of the hard drive still brings two advantages: access time obviously lower than that of a “Green” hard disk but also rates a little higher: Western Digital announces 154 MB/s for this model.
Note that the company does not indicate the number of hard disk platters.
