Toshiba Announces MN-Series HDDs: Up to 8TB

I have bought nothing but Toshiba drives in the last few years—their X300 series represents a pretty great value, especially the 5TB model, which hovers at around $150. While I have had zero issues with any of mine, the company is releasing a new series of enterprise-y drives that presumably last longer (Toshiba has even published the MTBF for these, which was somewhat of a secret with the X300s). I wish they would offer a new line of 5400 RPM drives, though, since less people are buying hard disks for speed these days and could do without the increased noise and heat of 7200 RPM.

The Toshiba MN-series family includes 4 TB, 6 TB and 8 TB models with a SATA 6 Gb/s interface (note that the higher-end model supports the SATA 3.3, whereas the others are compliant with the SATA 3.1). The HDDs feature 7200 RPM spindle speed, are equipped with 128 MB buffers, and use rotational vibration (RV) sensors that detect and compensate for transient vibrations in multi-bay NAS and server environments - this aims to ensure that the drives deliver consistent performance. Speaking of performance, Toshiba declares up to 230 MB/s sustained data transfer rate as well as 4.17 ms average latency time for the top-of-the-line 8 TB model.
