I'm building a new server from scratch, so I'm trying to figure out the best drives to buy.  Right now I have some Samsung Green drives, couple Seagate, and WD Red.  I'm looking at 12 drives to start (10 DRU, 2 PPU) and move to 24 drives (20 DRU, 4 PPU).  I am assuming a 5-to-1 DRU/PPU ratio is a good ratio.

Right now it looks like there is a $30 premium to go from WD Green to WD Red, and a $60 premium to go from WD Red to WD Black.

For performance on a budget it appears the WD Green are the way to go for the DRU, and WD Black for PPU. (10 @ $190, 2 @ $280 = $2460)
For a price/performance mix, WD Red for DRU, and WD Black for PPU. (10 @ $220, 2 @ $280 = $2760)  $300 increase from Budget
For all-in performance WD Black all the way. (12 @ $280 = $3360)  $900 increase from Budget, $600 from Price/Performance

Anyone had any experience with the Hybrid drives?  Did we get some data from shaun.arundell?  I'd like to put some hard numbers along side the costs to see if the performance justifies the cost increases.


Server HW: Norco RPC-4220 | Supermicro X7SPA-H-D525 | 4GB Mushkin SO-DIMM DDR3 1333 | LSI 9201-16i | Corsair TX650 | 64GB Corsair Vertex2 SSD (OS)
Server OS: Windows 7 64bit Pro
FlexRAID RAID-F 2.0 Update 12, Cruise Control [SnapShot RAID], 9 DRUs (9x3TB), 2 PPU (2x3TB)

you could also replace the Blacks with Red Pro or Se if they cost about the same. you get similar performance with better reliability rating. But in general I think the 5400RPM DRU with 7200RPM PPU is the best price/performance mix.

Regarding hybrid drives, remember that the SSD part doesn't act as a landing disk but stores the most commonly accessed data, so this would only be of benefit if you are doing lots of reading of the same data.
