In recent times, one of the hard drives in my PC started to present problems. The software Crystaldiskinfo began to display a status of “Alert”. Some s.m.a.r.t attributes. were not good and, worse, were having constant modifications, especially when the HD was very active.
Only the “Alert” It would be a cause for concern, But besides the HD started to present read errors, those in which the CRC does not confer. Bad sectors began popping up.
All the important data of this HD had backup, but keep losing files periodically and having to restore backup was not pleasant. The operating system is not in HD, but on it are my photos, videos, ROMs, games, the archives of the blog here and a few other items.
I decided it was time to make a upgrade. The faulty HD is a Seagate, ST2000DM001 model of 2.0 TB and 7200 RPM. Lately I've been having a lot of problems with Seagate. I tend to be loyal to certain brands, My HDs have always been of Quantum, until it was acquired by Maxtor and I started using Maxtor. Por fim, a Maxtor was acquired by Seagate and I started using Seagate. As the quality seems to have fallen over the year and with these changes, I thought it was time to go to another brand.
Unfortunately, in Brazil the options aren't very tired. Seagate has the most and are the cheapest. I would like to find a HD Hitachi, It has a reputation for being very good, but I couldn't find. My second option was to Western Digital, Since I have multiple external HDs that mark that never gave problems. So that was my choice.
I've always preferred hard drives of 7200 RPM, due to the increased speed. Today, as my OS and my programs are on SSD, the 7200 RPM are no longer as important, but still were desirable because this HD I too low my torrents, including ROMs, CHDS, and EXTRAs of MAME. Check for torrents, of DATs, rebuild sets, and everything is very expensive in terms of disk access.
The HD in trouble was 2.0 TB, but also I thought I'd have the opportunity to increase a little the size. With 3.0 TB already guarantee extra space as the amount of pictures and videos increase.
The Western Digital HD ideal for this situation would be some of the line Black. They have 7200 rpm and guarantee 5 years, being the top from WD for desktops. However they have fairly high cost and also are scarce in Brazil. What else I found were the lines Purple and Red, which are geared towards security systems and in, respectively, This is not the case. I found also some line Drives Green, desktop line of hard drives with 5400 RPM, ou something, Since Western Digital marketing always hid that information, preferring to use the name “IntelliPower”.
And what is Intellipower? WD responds:
IntelliPower is a balance between rotation speed, transfer rate and caching algorithms, designed to deliver both significant power savings as robust performance. Furthermore, GreenPower drives consume less current during startup, which allows more units rotate simultaneously and, consequently, the systems are faster and more accessible.
Yeah, said said and didn't say anything. And recently the WD decided to merge the rows Blue and Green. Stopped with the nonsense of Intellipower and began to show the actual rotation speed of the HDs. Here's the info on their website:
WD is helping to make the choice of their customers the right drive for your desktop and laptop easier. During the next few months will occur a fusion between the WD Green 5400 RPM with hard drives 3,5 inches (with capacity of up to 6 TB) and the WD Blue 7200 RPM with hard drives 3,5 inches (with capacity of up to 1 TB) which will be sold together under the brand name WD Blue. Product availability depends on each Distributor. See the specifications of the model above for more information about the expanded line.
They said they wanted to facilitate, But having different speeds on the same Hard line doesn't strike me as a big help. The fact is anyone who wants high capacity on Blue line, will have to settle for 5400 RPM, because the hard drives of 7200 rpm has a maximum 1.0 TB. Who want high capacity and high speed will have to go to the line Black same.
I opted then at HD Western Digital WD Green 3.0TB WD30EZRX. Is a model that a few days after it's gone from the WD Web site, but everything indicates that now he is the WD30EZRZ the line Blue, because the spec is the same, except for the speed of rotation which is now listed as being of 5400 RPM instead of the enigmatic “IntelliPower”. The warranty remains of 2 years. Both also have 64 MB of cache memory and both use SATA interface 3.
I received my HD Western Digital WD Green 3.0TB WD30EZRX sealed in anti-static plastic. The seal of the importer appears “7200 RPM”, but desconsiderei this information is clearly wrong.
Installed or HD Western Digital WD Green 3.0TB WD30EZRX, before starting the data transfer I ran some tests with the Crystaldiskinfo and using the CrystalDiskMark, and here's the data I got with them. Screens and transcripts:

Transfer so the data and everything is working perfectly so far. No more alerts of Crystaldiskinfo and no more bad sectors information.
