As to pricing I'm right there with you in that if they charge the same per GB I won't be happy with that. But the drives haven't even been officially released and they'll be around for one to three years on the market so I'll continue to adjust my view of them as facts develop.
As for the advertised write speed of 160mb/s, it was on some news sites late last year (around September), they reported that Intel claimed a write speed of 160mb/s on their new G3 SSDs.
Yes and the tested unit is not the one that would achieve that speed. You have to buy the highest capacity drive in the series to get the maximum advertised speed.
It's the same dirty secret with the OCZ SSDs and the Crucial SSDs and every other brand. Take these to examples
Corsair Performance 3
480MB/s read, 320MB/s write for 256GB model
410MB/s read, 210MB/s write for 128GB model
365MB/s read, 110MB/s write for 64GB model
C400 Performance to compare vs above
415MB/s read, 260MB/s write for 512GB model
415MB/s read, 260MB/s write for 256GB model
415MB/s read, 175MB/s write for 128GB model
415MB/s read, 95MB/s write for 64GB model
The Corsair loses speed on reads and writes as the capacity drops. The C400 loses speed only on writes and only when capacity drops below 256GB.
Where will Intel 320 Series stop dropping/gaining speed as the capacity changes? I don't know but I'm guessing based on the picture of the 80GB PCB that the 160, 300, and 600GB will all have the same performance unless Intel throttles one or more capacities. Assuming 160 is the max speed there will be a drop in speed for each capacity below that with 160 being faster than 120 being faster than 80.
By comparison lets add some other older SSDs
Manufacturer specs on maximum sequential write speeds compared to Actual test results for Sequential Write speeds:
Drive Spec Test
X25-M G2 160GB 100MB/s 101.2
X25-M G2 120GB 100MB/s ~101 same as 160GB within margin of error
X25-M G2 80GB 70MB/s 81.6
X25-V G2 40GB 35MB/s 37.7
C300 256GB 215MB/s 203.0
C300 128GB 140MB/s 131.1
C300 64GB 70MB/s 71.0
Corsair F120 275MB/s 136.6 or 214.8
Corsair F40 270MB/s 72.5 or 210.4
In those cases the tested drives from Corsair and Crucial tested worse than advertised and Intel tested better than advertised. The catch is we don't have per capacity specs for the 80GB 320 Series SSD to know if it is testing equal to, above, or below advertised specs.
So yes the quick review of the 80GB model doesn't meet the leaked specs for the entire line of 320 SSDs. That isn't a surprise. Just wait a few days until someone reviews the 300GB model or the 160GB model and see how much faster it is or wait for Intel to post the official specs and compare those.
