Have any reviews of the lower capacity 320s appeared yet? I haven't seen anything myself, beyond a table on the
AnandTech review which shows that the 160 GB version does have reduced performance specs. (And worse for the 120 GB.)
I haven't seen any reviews of the lower capacity Intel 320 series SSDs yet but did find some Xbench results for two for the smaller sizes at MacRumors:
Code:
Capacity(GB) 300 160 120 160(X25M)
Sequential(MB/s)
Uncached_Write[4K blocks] 221 164 134 107

Uncached_Read[4K blocks] 36 35 35 49
Uncached_Read[256K blocks] 208 211 206 204
Random(MB/s)

Intel 320 SSD (X25-M G3 Postville Refresh) Released!These are only indicative since they were run by different users on different hardware but they do suggest the following about the performance by size:
*Sequential reads are fairly constant across the different sizes
*Sequential writes diminish significantly for the smaller sizes, although all remain above the 160GB X25M
*Random reads are fairly consistent across the different sizes but all are below the 160GB X25M
*Random writes remain fairly constant across the different sizes for 4K blocks but all are below the 160GB X25M, while for the 256K blocks the performance dimishes significantly for the smaller drives but all remain above the 160GB X25M
Not being a SSD expert I'd be interested in the thoughts of those who are (e.g. dhanson865) but my impression is that based on performance, one should pay less per GB for the 320 Series relative to the comparable X25M drives. Since this hasn't happened yet, I'd either buy a X25M drive if I needed one now or wait for the 320 Series prices to drop...
