Question about Western Digital Hard Drives

post #1 of 10
Thread Starter 
Could anyone tell me if there is any performance difference in the following Hard drives..

WD Black
WD XE
WD SE
WD RE

I know the XE, SE, RE and targeted at business or pro consumers but I am wondering if there is any real difference in the transfer rates??

SE and RE for maximum storage space and maximum robustness. There is XE if you don't care as much about storage but you want maximum performance. Also the robustness of the (XE) drive is better then the other 2 with a 2 million hour meantime between failure

Basically:
  • RE: Pure raid drive with all bells and whistles (business grade)
  • SE: A cheaper version of the RE (more towards consumers)
  • XE: Less storage but way higher performance
  • Black: Consumer grade performance disk

Thanks that helps some, I wonder if there is enough difference to sort of justify the cost??

Maybe when you are building a big array I can see myself buying a SE drive, €5-10 cheaper per drive really adds up and reliability wise it's nearly the same as a RED.
As for the XE drive I don't really see a use for it when building a ordinary NAS... I don't know allot when it comes to storage so I don't know in what kind of situation you would want to trade the storage for performance. (maybe direct video editing)

One thing you have the keep in mind is that these offer a longer warranty then the ordinary drives like the black, green, blue so at least you know they are made to last longer.

Probably for the same reasons people buy VelociRaptors? From what I can see, the WD Xe is just the enterprise SAS 6Gb/s version of the VelociRaptor. Plus, it's 2.5" so you can pack them pretty densely. I remember seeing the 1U (or maybe 2U?) server in the office and it holds 8 2.5" drives. Practically inaudible, too.

Seriously, though, unless you need to run like 24 of these in a 4U case with hotswap or something for a 24/7 RAID array, I wouldn't bother. Besides, I'm not even sure if you can use SAS drives on regular SATA controllers. SATA drives on SAS controller yes but I don't think you can do it the other way around.

that is no problem as I have 2 LSI Raid Cards that are SAS or SATA biggrin.gif just need drives now. trying to decide best performance for the dollar...

Western Digital Launches WD Se Hard Drive Lineup for Datacenters and High-end NAS Units



From the above article, I don't think the WD Se is designed for 24/7 operation. It really does appear to be targeted more towards data centers utilizing replication rather than traditional RAID systems. That said, the Se seems to be a better option than the Blacks (and are priced similarly to boot). Obviously, the Re is better and the Xe is the best performance-wise. Newegg prices are as follows:

WD Black 2TB $160
WD Se 2TB $160
WD Re 2TB SAS $250

WD Black 4TB $300
WD Se 4TB $290
WD Re 4TB SAS $430

WD Xe 300GB $195

Really is up to you to decide whether the price premium's worth it. Pure performance though, obviously an SSD is better. Actually, I can't really think of any good reason to get the WD Xe 300TB for consumer applications when you can just buy a Samsung 840 Pro 256GB or similar for the same price.

Yes you are right about that and I am really considering either the 1 TB Black or the 1TB RE..
