RAID0 RED RE4 BLUE or BLACK 1TB??

post #1 of 2
Thread Starter 
Alright I need some help here.... What HDD is faster for sequential speeds in 2x RAID0? RED, RE4, BLUE or BLACK??

The reason I need help is because I'm confused, so....

RED is made for RAID, has 3 year warranty but is 5400 rpm, however.... I've seen a few reviews that show that it beats BLACK witch is a 7200 rpm HDD. I know RED is a single 1tb platter but really... is it faster? can someone confirm this?

BLUE, 2 Year warranty thinking.gif, 7200rpm HDD, not made for RAID, 1TB platter, so I can see how it beats BLACK in sequential.

RE4, made for raid, 5 year warranty, enterprise grade, 7200 rpm, close to BLACK performance? I donno.... and do I REALLY need these??

Black, 5 year warranty, faster then RED, BLUE, RE4? on speeds that I don't care, I only need high sequential speed. No model has a 1TB Platter as far as I know.


So..... apparently, RED and BLUE are faster then Black in sequential speeds but witch is faster? RED or BLUE? and for raid, do I really need a "made for raid" HDD? are the BLUE or BLACK not going to last long in RAID or something? other then TLER what other advantages is there with the RED?

What about reliability? does the warranty mean something? how reliable is the BLUE HDD?

I'm not sure about the RE4s at all, but Blues approach SSD speeds in RAID 0. In fact, two of them can sustain over 350MB/s up to halfway into the capacity. If you meed speed but not too much space, you can short-stroke them to further increase speed. Reds, given their rotational speeds are around 70% as fast as Blues since both use the same platter densities. Here's the proportion for 1TB drives, solve for X: 5400/7200 = X/100 so 5400/72 = X. Go from there; I am on my phone and refuse to do division in my head. Reds just have firmware that helps them out if there's an error in the array but are intended for NASes, not performance PCs.

Warranty doesn't mean anything from what I can see. My SSD has a two year warranty (or three? Can't remember) and the Pro model has five. The Pro seems no more or less reliable. Likewise, the Blues are quite durable, probably more so than the Blacks. Fewer platters means the mechanical parts move less mass (less stress) and have fewer points to fail.
