Those are good numbers
Runs cool. 5 degrees less than my 2 TB WD Black
3 year Warranty
Cons: Not easy to find the info that indicates which security systems
are designed to take full advantage of the Purple lines features. The average Joe might not even think to look.
Fully compatible with only very expensive pro or rich guy surveillance systems
3 year warranty. I know I have it in Pros too.
Other Thoughts: Everywhere I go there are cameras recording data which means big sales for the camera makers and thus the storage industry. WD is attempting to get their share of this market with their Purple line of drives. The "tag" WD uses that makes these drives surveillance specific is termed "Allframe". The advantage of the AllFrame technology is possible only with host controller support. The vendor must be on the WD compatibility list to take advantage of the surveillance-specific features in the Purple drives.
On WD's compatibility page is a list of 27 vendors and the models that support Purple. Most of the names on the list
are not familiar to me. I started searching Newegg. Newegg has ~130 vendors listed under the heading:
Security & Surveillance > Video Monitoring Kits / All in One Systems. I selected at random just a couple; Geovision and QNAP, to see if what I was thinking was correct. I was thinking that the qualified vendors are more then likely "professional"
vendors. By professional I mean anything that doesn't have to do with home or very small business security. If price tag
has anything to do with my theory then I am born out. The QNAP offerings range in price from $982 to $4,902. I am not spending that to protect my home or very small business. If I am a large, well heeled company then my budget may allow for that but for my home, not happening.
What the people that do the reviews on Newegg ARE buying range in the $200 to $300 area. LaView, a popular well reviewed vendor is not on the WD compatibility list. Neither is 7modo, Night Owl and many more. This means that the Purple may not be money well spent for home surveillance.
Is it money well spent for essential video security recording for large business? Maybe if reduction of frame loss,
improved playback and an increased number of drive bays supported is important.
The first data I concern myself with when shopping hard drives is rotational speed. 7200 or 5400? WD has obfuscated,
for reasons I can only speculate on but won't, rotational speed with the "Intellipower" designation for the Purple drives RPM. HWInfo 64 reports the RPM's as 5400 which is plenty fast enough for the purpose of this drive, namely video surveillance.
I am using this drive to store all my video: Home movies, DVD's, Blu-Ray's, etc., etc. In almost of month of use it has been flawless for local and wireless networked viewing.
This is a very good drive. If you are a large company interested in quality surveillance then there is no better choice according to the data sheets. If you're a small company or homeowner on a $300 budget you will probably not be able to take advantage of the primary selling feature
of this drive. BUT that does NOT mean you are making an incorrect choice as I wrote this is a solid HD.
If you just want a large fast drive to store and access video this is a very good choice.
This review is from: Zalman ZM-MC1 Multi-connector PS to Add Fan
Two fan speed options
Probably won't break during use
Cons: Software can't monitor fan speed when fans attached to this
Other Thoughts: I received this item many years ago with a Zalman purchase but never needed to use it so I just tossed it in the dongle drawer. My backup computer's fans were louder then I wanted so I was looking to buy a fan control. None of the products thrilled me. I recalled this part. My mobo has only one 3 pin fan connector so I had to use 4 pin molex power for the case fans. Using this and the 5 v lead the fans spin slow enough that they are barely audible. A good choiceREAD FULL REVIEW
Pros: Good Price
Thermal Grease INCLUDED
Fits as advertised
Pretty Darn Quiet
The power cable is not too long so it doesn't get caught up in other fans
Cons: I can't think of a one
Other Thoughts: I wanted a CPU fan that was quieter then what I had on my AM2. At this low price this model was worth a shot. I have had several Zalman CPU coolers over the years and did not regretted buying Zalman. I still don't. The install was a breeze.
Consider what you want the cooler to do. If it is just to be silent this is a good choice. It won't cool your i7 Humpa Humpa gaming rig CPU though
