This Just In: OCZ's Vertex 3 MAX IOPS 120GB, The New Mid-Range King?

I mentioned in our Mid-Range SSD Roundup that most SSD vendors like sampling the best balance of capacity/performance when it comes to SSD review samples. For the SandForce SF-2281 with 25nm NAND that just happens to be 240GB. Unfortunately there's a pretty big fall off in performance when going from 240GB to 120GB due to the decrease in total number of NAND die (8GB per die x 32 die vs. 16 die). I've explained this all before here.

Enter OCZ's MAX IOPS drive. Using 32nm Toshiba Toggle NAND instead of 25nm IMFT ONFI 2.x NAND the die capacity drops to 4GB, which means you get twice as many die per NAND device. The end result? 240GB Vertex 3 performance for slightly more than 120GB Vertex 3 pricing.

 

I ordered the 120GB MAX IOPS drive at the beginning of the week and just got it in yesterday so I've only had a small amount of time to test with it thus far. Check out the 120GB MAX IOPS drive vs. the Intel SSD 510 in Bench using our 2011 storage test suite. Expect the full review in the coming days.

The 2011 Mid-Range SSD Roundup: 120GB Agility 3, Intel 510 and More Compared

A year ago whenever I'd request an SSD for review I'd usually get a 128GB drive built using 3x nm 4GB 2-bit MLC NAND die. These days the standard review capacity is twice that as most drives ship with 25nm NAND, using 8GB die. Seeing a bunch of scores for 240GB+ drives however is frustrating to all involved. At these capacities you're almost always looking at two die per NAND device, which has significant performance benefits due to interleaving. Most SSD controllers have eight NAND channels and with sixteen NAND deviecs with two die per device that's four NAND die that the controller can interleave access between for each channel. The 128GB drives by comparison halve the number of NAND, which only allows the controller to interleave requests among two die.


How read interleaving works on a single channel

Not only are these 240GB+ drives the best case performance you'd see from a particular SSD, they are also very expensive. At around $2/GB you're looking at over $500 for a high end 240GB+ SSD. I've spent the past few weeks gathering modern SSDs with 128GB of NAND on-board to provide a look at a more balanced point in the price/capacity spectrum.

OWC Mercury EXTREME Pro 6G 120GB SSD Review

Legit Storage Reviews

OWC does SSD's 6Gbps Style

It wasn't that long ago we had a look at the beta OCZ Vertex 3 drives with the next generation SandForce controller on board. Those are just now hitting the shelves and it's been a bit surprising that no other SandForce 6Gbps drives have made their way into the market (although Corsair just announced their new Force Series 3 lineup). Finally, someone else has stepped up. Other World Computing (OWC), most notably known as a retailer and manufacturer of Mac related hardware and software including memory, hard drives, accessories, etc. has the Mercury brand which is uniquely theirs and used across an array of products. Their latest offering is the Mercury EXTREME Pro 6G line of solid state drives featuring the SF-2200 controller and a 6Gbps interface.

OWC Mercury Extreme Pro 6G

Available in 120 GB, 240 GB and 480 GB capacities, they are priced at $319.99, $579.99 and $1799.99 respectively. As with the all other SandForce controlled drives, they support TRIM and idle garbage collection and don't rely on a cache for data buffering as you'll see when we take a look inside the case. Speaking of TRIM, since OWC caters to the Mac crowd, OS X Lion is rumored to support TRIM although there is conflicting reports on whether or not this will work with drives outside of Apple's build offerings. I can say that for the current OS X version (10.xxx) there is a way to enable TRIM by running this free app and I can confirm that this works admirably as I have been using it on a SandForce based SSD with a unibody MacBook Pro. Obviously, this is not sanctioned by Apple so use at your own risk.

OWC Mercury Extreme Pro 6G

The drive we received was a pre-production model and the sticker shows that it has RC1_3.0.0 firmware which is not the final version. The exterior and branding should not change and is composed of an attractive blue aluminum case which might pair up nicely with other blue components like our ASUS P8P67 Deluxe board.

The front sticker sports a small American flag icon that signifies that the drives are designed and assembled in the USA albeit with a mix of domestic and imported parts. For more on these parts, let's have a look inside.
