We reported on Intel's SSD 330 weeks ago, but today is the official announcement of the drive and its availability in the channel. Unlike previous 300 series drives, the 330 isn't based on Intel's own controller - it's the second SandForce SF-2281 drive in Intel's lineup.

The 330 differs from the SandForce based Intel SSD 520 in a couple of key areas. The 330 uses lower p/e count NAND (still Intel 25nm MLC) compared to the 520, reducing Intel's rated lifespan from 5 years of 20GB of writes per day to 3 years under the same workload. Intel's ratings have historically been conservative, so I'd expect that the 330 would last much longer than 3 years for the vast majority of workloads - particularly based on previous calculations on the topic. With a 3 year usable lifespan rating however, Intel dropped the limited warranty on the 330 to 3 years as well.

All of this results in a significant reduction in price compared to the 520:

SSD Pricing Comparison
  60/64GB 120GB/128GB 180GB
Crucial m4 $79.99 $154.99  
Intel SSD 520 $109.99 $184.99 $289.99
Intel SSD 330 $89 $149 $234
Kingston HyperX 3K   $169.99  
Samsung SSD 830 $94.99 $174.99  
OCZ Vertex 3 $98.99 $159.99  
OCZ Vertex 4   $179.99  

In fact, the Intel SSD 330 appears to be the cheapest SF-2281 drive on the market today. Interestingly enough it's only available at three capacities (60, 120 & 180GB), while the Intel SSD 320 was available in far more models going all the way up to 600GB.

Performance ratings are down compared to the Intel SSD 520, although it's not clear whether these are artificial limits or not:

Intel SSD 520 vs. 330
  Intel SSD 520 120GB Intel SSD 330 120GB
Capacity 120GB 120GB
Controller SF-2281 SF-2281
Random Read Performance (Up to) 25K IOPS 22.5K IOPS
Random Write Performance (Up to) 40K IOPS 33K IOPS
Sequential Read Performance (Up to) 550 MB/s 500 MB/s
Sequential Write Performance (Up to) 500 MB/s 450 MB/s
Warranty 5 years 3 years
Price $184 $149

Presumably Intel's SSD 330 uses a similar custom firmware solution to the SSD 520, which should hopefully keep it safe from any SF-2281 related BSOD or other instability.

    Do you plan to review the Mushkin Chronos SSD anytime soon? Reply

    The Mushkin have been doing pretty good with SSD's, I personally have one and I chose it after reading a lot about all of the brands.

    I think it really should be considered in Anandtech in general.

    Note: do not run a cloned drive with original in Windows system (Windows doesn't know how to respond and deletes a boot.ini file)

    amazon priced 330 series 120GB at $128 and now for a week they are putting $145! can I expect a price correction(reduction) anytime soon? Reply

    Just did a new build this weekend with the 180G version and it BSODed with the PC at idle. Ran it with a Sabertooh z77 and i7-3770. So far only one BSOD, but scandisk did find some issues and fixed it. Reply
