Intel X25-M G2: Dissected and Performance Previewby Anand Lal Shimpi on July 22, 2009 6:00 PM EST

For the most part, Intel doesn't let anyone else manufacture drives using its controller (the lone exception being Kingston). Indilinx and Samsung however both sell their controllers and designs to many other vendors, who then repackage them and sell them as their own SSDs. The table below is a decoder ring of the drives I tested and their equivalents in the marketplace:
|Drive||Controller||The Same As|
|Patriot Torqx||Indilinx Barefoot (MLC)|| |
Corsair Extreme Series X128
|OCZ Agility||Indilinx Barefoot (non Samsung MLC)||N/A|
|OCZ Vertex EX||Indilinx Barefoot (SLC)||SuperTalent UltraDrive LE|
|OCZ Summit||Samsung RBB (MLC)||Corsair Performance Series P256|
While I used the Torqx from Patriot as my Indilinx MLC drive, it's the same drive and uses the same firmware as OCZ's famed Vertex drive or the new Cosair Extreme Series SSD. The only exception on this list is the OCZ Agility. The Agility uses the same Barefoot controller as the Torqx, Vertex, UltraDrive ME and Corsair X series, but it uses non-Samsung flash memory to lower cost. The Agility currently ships with either Toshiba or Intel flash, but should be roughly the same performance as the other Indilinx MLC drives.
I included the SLC drives as a reference point, but for desktop use they are overkill. Not only is their firmware not optimized for desktop usage patterns, but they are far more expensive on a cost-per-GB basis.
All of the drives used the latest firmwares at the time of publication.
The table below is the pricing comparison I went through yesterday:
|Drive||NAND Capacity||Cost per GB||Price|
|Intel X25-M (34nm)||80GB||$2.81||$225|
|Intel X25-M (34nm)||160GB||$2.75||$440|
|OCZ Vertex (Indilinx)||64GB||$3.41||$218|
|OCZ Vertex (Indilinx)||128GB||$3.00||$385|
|Patriot Torqx (Indilinx)||64GB||$3.48||$223|
|Patriot Torqx (Indilinx)||128GB||$2.85||$365|
|OCZ Agility (Indilinx, non-Samsung Flash)||64GB||$2.77||$177|
|OCZ Agility (Indilinx, non-Samsung Flash)||128GB||$2.57||$329|
|OCZ Summit (Samsung)||128GB||$3.04||$389|
The new 34nm drives were supposed to start shipping yesterday, but I've yet to see them available online. It's also worth mentioning that Intel doesn't give out street pricing, only 1,000 unit pricing. The street price of the X25-M G2 drives could be higher at first, similar to what we saw with the 1st gen drives, eventually leveling off below the 1Ku pricing.
