What workload are you talking about?
If there are loads of small random writes then you need to buy a drive like the X25-E or the new 710 Series.
The 710 Series is priced at ~$700-$750 per 100GB and is available in 100GB, 200GB and 300GB capacity.
(price based on 4K NOK ex.vat for the 100GB and a 5.5 exchange rate)
