Thanks to advances in manufacturing and 4 KB sectors, we finally have 2.5" hard drives with 500 GB per platter and a notebook-friendly 9.5 mm Z-height. Thanks to their high data density, even power-friendly 5400 RPM drives offer impressive transfer rates.

Toshiba MQ01ABDxxx (MQ01ABD100)

We've seen Toshiba focus on physically small drives for quite some time, and the company offers more models in this segment than any other hard drive vendor. Searching Toshiba's website for 2.5" client-oriented drives turns up an astounding 41 product families. So, we tried sorting the disks according to five use cases: computing, consumer electronics, multimedia/video, automotive, and industrial. Even then, we still had a difficult time finding the right product among the mass of candidates. Computing alone is so general that it doesn't really help us narrow down the field at all.

The MQ01ABDxxx family appears in three of the five applications: computing, consumer electronics, and multimedia. According to Toshiba, its MQ01ABDxxx is optimized for quiet, energy-efficient operation, and should be well-suited for use in mobile PCs, desktop PCs, game consoles, and DVRs.

With a spindle speed of 5400 RPM and a data cache just 8 MB-large, maximizing transfer rate wasn’t a major design criteria. The MQ01ABDxxx-series sports a 3 Gb/s SATA interface complemented by Advanced Format support, which presents 512-byte sectors to the operating system as it internally uses 4 KB sectors.

We're testing the flagship MQ01ABD100, which has a capacity of 1 TB and costs about $94 online. Although it's not the only 9.5 mm-high 1 TB drive we have on-hand, cramming that much data onto two platters still is a major technical achievement. As we already pointed out, a 12.5 mm three-platter disk simply doesn't fit into the hard drive bays of most notebooks.

The Toshiba MQ01ABD100 packs a whopping 744 Gb into one square inch of magnetic media, the highest data density in our test. Meanwhile the 1 TB Hitachi Travelstar 5K1000 has a slightly lower, yet still impressive, data density at 694 Gb per square inch.

Performance

Despite the fact that it's primarily positioned as a quiet, power-saving storage product, the Toshiba MQ01ABD100 demonstrates impressive results in our h2benchw benchmark. With an average read/write rate of 89 MB/s, it pulls ahead of the Hitachi Travelstar 5K1000 by a slim margin. Other drives capable of similar performance include Seagate's Momentus XT and Western Digital's Scorpio Blue WD10JPVT. Not unexpectedly, this Toshiba MQ01ABD100 loses in a direct comparison to 7200 RPM disks like Hitachi's Travelstar 7K750.

Toshiba specifies an access time rating of 12 ms, but our measurements come in significantly higher than that at 17.8 ms (read) and 21.3 ms (write). Being the slowest of our four new test candidates, we wonder if there is some correlation with this disk's high data density? Even still, although its access times look really slow, that's probably not particularly relevant to the target markets this drive is intended to satisfy.

An average of 0.5 W in our idle power draw test is beaten only by Western Digital's Scorpio Blue and Seagate Momentus XT. The maximum power draw is just 2.9 W, which confirms the MQ01ABD100 as a “green” drive.

    "9.5 mm Z-height."

    Isn't that like saying 9.5 mm "vertical height".
    There is no X-height or Y-height :-)

    theconsolegamerWestern Digital and Seagate deceiving Hitachi and Samsung consumers since The Hitachi and Samsung drives are still manufactured in the same factories they were before.. just cause ownership changes doesn't mean performance or features and characteristics of the drives are going to change right away.. that will take time to happen, and who is to say if they will change for the better or worse..

    Z-axis is height in any system I am aware of.

  • Two hitachi drives have failed for me in the past year, i've got one Samsung drive that's been running for over two years(no issues) and a scorpio black that's much better. I don't know if it's just me but I don't really trust Hitachi HDD's anymore

    Some of these drives are sold not only as low power but also as low noise options so I think a noise benchmark would have also been useful.

    I actually have a Western Digital Scorpio Blue WD10JVPT as the data storage drive in my desktop PC (I use a 64GB SSD as my boot drive) and the reason I went for it is exactly this, i.e. low noise, and I can say that it does deliver on that. It is clearly slower than my old 1TB 3.5" Samsung HDD at 7200RPM with 32MB of cache but I must say that it is noticeably quieter. And the noise difference comes in two flavors, on the one hand the actual noise generated by the drive motor which is clearly noticeable on a 3.5" 7200RPM drive but much less so on a 2.5" 5400RPM, and on the other hand in terms of the drive vibrations which are then passed onto the case to create a very disturbing humming noise even through the rubber vibration insulators I had installed on my old 3.5".

    you sir have no experience in the real world or in business i see. try being a business analyst. first thing to change is the staff like within 6 weeks and still goes on for 6 months to 2 years, then the thinking which is also why alot of staff who can't cope or disagree are gone. while doing all the contracts for everything are evaluated and everything that can be cut to help pay for the acquisition is gutted as much as is still profitable, that means whole segments can and typically are sold off if the buyer has a cheaper solution already implemented in such types of acquisition deals. supply contracts are bought out or cancelled if they don't meet profitability requirements ASAP.

    so what you said isn't true because what happens in reality is not only does the staff change almost immediately if they are not superior in EVERY WAY (cost most importantly) parts and materials are changed very quickly if they are not superior in EVERY WAY (cost most importantly) any segment that can be cut to improve profitability is cut.

    typically 30-66% of a bought out company gets cut as it is duplicate of what the buying company already has and can supply and or make already. i have seen as much as 90% get cut and as little as 10% cut.

    when dealing with american companies, labor force seems to be the most change made due to costs. i have seen labor forces that were 300-500% more cost effective for the work they get done cut due to labor costs as it meant less billable hours and profitability in squeezing a client for. those are some of the saddest things i have seen happen after an evaluation. i have also seen the same thing happen to products that were superior gutted down just so some one else can say they made the best on the market with out ever having to improve their product, change their ways or spend more money countless times.

    the aim of buying out another company in the same business in a bad economy is to eliminate competition and or buy them for their IP/patents, not to spend more money in a bad economy, i don't think that can be stressed enough companies are just fighting to stay in business in a bad economy.

    I am afraid I do not agree with your view. In the current economy many mergers and acquisitions are made in order to consolidate a business and to increase the market share. If say you have 20% of the market and the company you are buying has 10% of the market you don't close down it's manufacturing capacities just to get rid of competition. If you do that you run the risk of not being able to deliver the capacity that you are supposed to deliver to your clients because you can't possibly increase the production in your own facilities to make up for the 10% you close down. Also, most companies these days are listed on the stock market and the fundamental aspect of such a company is that year on year it has to deliver growth to its shareholders. In a bad economy it is difficult to achieve organic growth and many businesses resort to mergers and acquisitions to deliver that growth although quite often that is more on paper that in actual fact. Also, in the case of companies in the HDD business the bulk of the production facilities are already base in low income economies such as China, Thailand, etc. and as such it is simply not possible to reduce the production costs even further through a reduction in the cost of labor.

    The one situation when you would buy off a competitor just to close it down is when there is an excess production capacity on the market which is driving down prices. In that situation you would try to reduce the level of supply so that you can get an increase in prices. However, in the HDD business that's not the case as production levels have only just recovered to the levels they were at before the floods in Thailand which took out a number of large HDD facilities and created major shortages on the market. This means there is hardly an excess in production capacity so it does not make business sense to close down facilities that have just been restarted. Plus, these acquisitions have been made for a cost which is not negligible and it is unlikely that cost can be offset by an increase in prices generated by a shortage in supply.

    Anyway, there's a lot more I can explain in terms of business policies and so on but I just don't have the time so in short I agree with techcurious in saying that right now the facilities that have been taken over are still producing drives and will still do for a while. That is not to say that will still be the case in few years time but that is definitely the case at the moment.
