I've got a WD Green already, but might be getting a Purple because the price is good.

Can I use a WD purple as a regular desktop HDD or put it in my home server? I've looked on userbenchmark and it says it gets about 150MB tops for both read and right, but my WD Green is only 100MB~ both, which I'm fine with. It's only really gotta fill a gigabit speed. But even then, this drive is more for temp cheap storage. Will find out if I need to expand much more then 1TB.

Thanks,

when I bought my array, I opted to pay extra for the reds. they ran super cool and I've never had an issue with speed on 300/300

The WD Purples are designed for surveillance use only and do not have any error correction to avoid loosing a video feed. If you try to use it for data storage, you run the chance of loosing or corrupting some data. Using it in a server is pretty much guarantees the RAID will break.

The WD Reds are intended for use in RAIDs. The regular Reds don't get the best reviews. The Red Pros are better but cost more.

The 5400rpm Blues are much better suited for regular data storage than the Purples and Reds. Before I went all SSD, I used them (and their predecessors, the Greens) for backup drives. Since my desktop machine runs 24/7, I preferred to use the WD blacks for their more robust construction and the five year warranty. However, for temporary storage, the Blue would be your best choice.

Ended up buying a Seagate 2tb BarraCuda, early May. Can't remember why I chose it, but it was probably because it was the cheapest under a certain price. Hopefully it will hold me off for a good while and I can look into killing off some of my IDE drives.
