SSD arent good of servers?

post #1 of 6
Thread Starter 
the IOPS would be very beneficial for companys and servers also their speeds.

price wont be much of an issue. but longevity would. so would the current SSDs be a good idea for server/company use? vertex 2. over a lifespan of 5-10 years?

I have just a piece of insight, you should search further; it should work with excellent results if you take 2 precautions. The idea is that what would matter is to have SSDs that have low write amplification (and sandforce's vertex 2 are very good at this) and spare space as much as possible. Sandforce enterprise drives have if I remember correctly around 27% of the flash in spare area (unallocated), while consumer drives like the Vertex 2 have only 10%. If you buy a consumer drive and use it in a sever environment when creating the partition you shouldn't allocate all free space, you should leave about 15% unallocated.
The last thing I wanted to say is you should try to buy an SSD with 34nm NAND and not with 25nm NAND; the 34nm flash lasts twice as much (10k writes vs 5k writes for the 25nm), but I think the current Vertex 2 ships with 25nm. Corsair's Force SSDs still ship with 34nm flash; another good option for an enterprise SSD would be the Intel X25M which is cheap(ish), 34nm, low write amplification and can run a similar number of IOPS as a Sandforce drive.

would the high stress environment wear out the SSD prematurely? we would nee quite a few in raid 5. around 2tb worth...

As with all servers..... We need to the know the usage/workload before any recommendations. For enterprise use, I would not use consumer parts. OCZ sells the Vertex Pro (SLC) and Ex (MLC) models which contain a super capacitor in case of sudden power lose and they allocate greater space for wearing.


MLC SSDs can substain 3000-5000 P/E cycles. Depending on the number of writes daily, that may mean 1 year or 10 years. SLC SSD can substain 50,000-100,000 P/E cycles.

Can't you also do SLC SSD's, the ones that go into the PCI-e Slots and do 500+ MB/s, those don't wear out do they?

If money isn't a problem you should get this
http://www.newegg.com/Product/Produc...82E16820227581

Its way expensive, but i don't think that one will wear out at all, although im not sure.

they have 2TB one's like that, and that one is cheaper, but its MLC, the one that wears out.

INFO ON SSD'S SLC v MLC: http://forum.notebookreview.com/hard...lc-vs-mlc.html

i found that after posting, and im not sure if its 100% accurate, but if SLC drives can last in excess of 150 years with 100gb of writing a day, then that probably isn't such a bad deal for a business.
