NAND Flash and Value
The SSD 320 is the first Intel drive to use 25-nanometer NAND Flash, a significant die shrink over the 34nm memory used in the X25-M. With the smaller dies, Intel saves money on production costs, savings the company says it is passing along to consumers VGP-BPS13 and OEMs.
The drive comes in capacities of 40, 80, 120, 160, 300, VGP-BPS13A/Q and 600GB with Intel prices of $89, $159, $209, $289, $529, and $1,069, respectively. Those prices are roughly in line with the street prices of competitors such as the OCZ Vertex 2 ($209 for the 120GB) and the Samsung 470 Series ($249 for 128GB, $499 for 256GB). However, if retailers offer any discounts off of Intel's prices, the SSD 320 could be a huge bargain
Technology and Features
With the launch of the SSD 320, Intel has updated its controller, with the goal of dramatically improving performance, particularly write speeds. However, the drive does not take advantage of the new SATA 6Gb/s interface that just become available on notebooks for the first time with the release of Intel's 2nd Generation Core Series processors VGP-BPS13A/B and chipsets in January 2011. This means that the SSD 320 will work with these newer notebooks, but it won't achieve the groundbreaking speeds of Intel's new SSD 510 (starting at $369 for 120GB). That drive is designed specifically for SATA 6Gb/s and promises speeds nearly twice those of the SSD 310.
In addition to faster performance, the SSD 310 offers improved security VGP-BPS13/B and reliability. Out of the box, the drive supports 128-bit AES encryption, allowing you to set a password for the drive that will prevent its data from being accessed if its ever stolen. It also keeps your data saved, even in the event that your computer loses power before it has a chance to shut down and clear the drive's cache.
Synthetic Tests
To get a baseline idea of what to expect we ran the SSD 310 through CrystalDiskMark 3.1, a synthetic benchmark that measures theoretical read VGP-BPS13B/B and write performance. However, before testing, Intel warned us that a theoretical test such as CrystalDiskMark might not show off the drive's best write performance because it doesn't "exercise the device long enough to reach its steady state."
Verdict
The Intel SSD 320 returns Intel to its rightful place amongst the performance leaders in the mainstream SSD category. Though the drive trailed competitors from Samsung, OCZ, VGP-BPS13B/Q and Crucial on many of our tests, it was usually within just a few milliseconds of the leader. Whether you're buying the drive as an upgrade or getting a brand new notebook with an Intel SSD 320 inside, you can buy with the confidence that that you're getting a fast performer that's comparable to the best SATA 3Gb/s drives on the market.
If your notebook is one of the new systems that has SATA 6Gb/s ports, you should definitely choose a drive like the Intel SSD 510 or OCZ Vertex 3 that takes full advanage of that interface. If you are shopping for a mainstream SSD upgrade, the Samsung 470 series offers slightly better overall performance, but the Intel SSD 320 should be near the top of your list because of its strong combination of security, reliability, VGP-BPS13A/S and performance.
