Benchmark Results: Streaming Reads/Writes And 4 KB Random Reads/Writes
Hitachi's Travelstar 7K750 handles streaming workloads best. However, it's trailed quite closely by Western Digital's Scorpio Blue WD5000LPVT and Toshiba's MQ01ABD100. Although the Hitachi Travelstar 5K1000 falls further behind, it's still no slouch when it comes to streaming.
Typically, disks with high spindle speeds and low access times shine in random read/write tests. However, the three 5400 RPM disks take the lead compared to our lone 7200 RPM sample in Iometer's random read/write test.
Western Digital's Scorpio Blue WD5000LPVT is the fastest, followed by mid-range performances from Hitachi's Travelstar 5K1000 and Toshiba's MQ01ABD100, with the Travelstar 7K750 finishing last, despite its 7200 RPM spindle.
Isn't that like saying 9.5 mm "vertical height".
There is no X-height or Y-height :-)
Z-axis is height in any system I am aware of.
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.
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.
