Toshiba Corp. has finally started to sell its 2.5” hard disk drive with extreme 3TB capacity in retail. The drive is not compatible with the vast majority of mobile personal computers, but can be installed into servers and network area storage (NAS) systems.
The Toshiba MQ03ABB300 hard disk drive with 3TB capacity is based on four perpendicular magnetic recording (PMR) 750GB platters produced by Showa Denko K.K. (SDK). The HDD features 5400rpm spindle speed, 16MB cache, Serial ATA-6Gb/s interface, 512e advanced format and 5.56ms average latency time. The drive is very power efficient for its capacity: it typical power consumption is 1.7W, whereas its idle power consumption is 0.7W.
Since the hard disk drive relies on four magnetic platters, it is 15mm thick – two times thicker than mainstream 2.5”/7mm HDDs – and cannot be installed into contemporary laptops. Toshiba positions its MQ03ABB300 as an ultimate solution for various storage systems that rely on 2.5” HDDs.
Toshiba introduced the record 3TB 2.5” hard disk drive in January and started to sample it with select customers in May. At present, the drive is used inside Toshiba’s Canvio Connect II 3TB as well as Western Digital’s My Passport Ultra external HDDs. This week the 3TB hard drive finally showed up in Japanese retail and is available for ¥22800 ($189, £125), reports Akiba PC Hotline. It is noteworthy that the pure drive costs more than external storage solutions on its base, which are available for $150 – $170 in the U.S.
Although Toshiba’s MQ03ABB300 continues to be a unique HDD, there is also a 4TB 2.5”/15mm HDD model from Seagate Technology (which are sold under Samsung brand). The latter is used inside portable external storage devices only, whereas Toshiba’s product can be “officially” used everywhere as the company designed it with NAS (and vibrations) in mind.
While the Toshiba 3TB 2.5” hard drive yet has to make it to the U.K., it is possible to buy Western Digital My Passport Ultra 3TB external HDD for £123.95 inc VAT. The Samsung M3 4TB external drive is available for £149.95 inc VAT.

KitGuru Says: If you own a NAS that uses 2.5” drives and is compatible with 15mm HDDs, then it is now possible to upgrade its capacity with the Toshiba MQ03ABB300 hard disk drives. They are not exactly affordable, but they are unique and designed for NAS environments, which means enhanced durability and reliability.
It’s dimensions look very similar to a 2TB Toshiba drive I currently use for my steam library… I hope this means that their 2TB drives will now be a sensible fatness.

So, Samsung’s M9T 2TB laptop drive is only 9.5mm thick, which is the standard thickness for laptop drives. But has 3 platters. So why didn’t Toshiba make their 3TB laptop drive be 12.5mm thick? that should be enough for 4 platters, since, the industry has shifted 1 platter laptop drives from 7mm thick to 5mm thick. 2 platter drives from 9.5mm thick to 7mm thick, and 3 platter drive from being 12.5mm thick to now 9.5mm thick (like the Samsung M9T).
Also, Seagate must be using 5 platters to get 4TB in a 2.5″ drive, yet their drive is 15mm thick too, indicating further that Toshiba could have put it in the 12.5mm form factor, so it could be used in some laptops, like the Asus G50VT and others and also the optical bay of laptops with the hard drive caddy.
And now Seagate has developed a 1TB/platter 7mm thick laptop drive, so 2TB at 7mm. Could be 3TB at 9.5mm or 4TB at 12.5mm.
Is there a NAS with 4 bays that is only 2.5″ (no 3.5″, so less bulky than a standard NAS) and 4TB / 15mm compatible? checked google, qnap and synology, no luck there…the only real option for small NAS and large space is limited to 12.5mm drives (3TB drives) and the ds416slim, at this moment. Are there any alternatives? Or will I have to wait until 12.5mm 4TB drives will come out?
