Toshiba Launches 7,278 rpm 2.5-inch HDD Series with 7 mm Height

[btarunr]

Toshiba Corporation today announced that it will expand its family of small form factor 2.5-inch HDDs with a new series that packs up to 500GB of data storage into a unit with a height of just 7mm. The new "MQ01ACF" series will start shipping from August 30.

The "MQ01ACF" series is Toshiba's first 7,278rpm, 2.5-inch product with a 7 mm height. The series offers two models: the "MQ01ACF050" with a recording capacity of 500 GB and the 320 GB "MQ01ACF032". A maximum internal transfer rate of 1,850 Mbit/s is realized by improvement to linear recording density and the 7,278 rpm rotational speed. Implementation of the 6 Gbit/s SATA interface also boosts data transfer rates over those of current models.



The slim "MQ01ACF" series is suitable for laptops and ultra-thin notebooks, especially for high-end PCs offering high speed data processing.

Capacities:

• MQ01ACF050: 500 GB
• MQ01ACF032: 320 GB

This is actually really sweet.

7278rpm seems strange.
usually, the rpm should be 7200.

Yes, but that's how they made the driver quicker.

i think the performance is realized by high density more than rpm.
High rpm improves seeking time.

Well, the article says otherwise, but I'm no engineer.

The density is in fact where the biggest gains are. The 7278 rpm spindle speed is an oddball (if not some typo), speed for some unknown reason. 2.5" drives are horribly slow even at 7200 rpm compared to a 3.5" drive. That's why SSDs make such a huge performance improvement in laptops.

Maybe somehow it's create synchronous situations?

2.5" drives should be faster than 3.5" drives that's why Velociraptors are beneficial.

 

[RejZoR]

No, i want a 7293,8 RPM drive!

must be noisy as f* like all 2.5" hdd's with 7k2rpm :/

Here's a secret: 7200RPM drives don't run at 7200RPM.

The max speed is ~7280rpm, but is never constant.

My old Velociraptor 10K rpm drive is dead silent...

Actually the 2.5 drives are slower than 3.5 ones. Is all about physics. Velociraptors are faster because they have 10K rpm, better heads and CPUs inside...
