Second-Gen SandForce: Seven 120 GB SSDs Rounded Up

The popularity of SandForce's first-gen controller is translating to a lot of traction with its 6 Gb/s offering. Five SSD vendors sent us seven 120 GB models based on the second-gen logic. What makes them different? An extensive benchmark suite tells all.

If you're on a limited budget, there are ways to take advantage of the benefits of SSDs without breaking the bank. Platforms like Intel's Z68 Express pave the way for SSD caching. The caveat is that a good SSD delivers incredible read and write performance. Caching only really exposes the solid-state technology's advantage in read speed, though. Because data must be kept synchronized between the SSD and hard drive, writes hover around the disk's best effort instead. That's why we consistently recommend you manage your storage space manually. The ideal setup involves a large-enough SSD for your OS and apps, while a separate hard drive is used to store all of your movies, music, and pictures. But what's a "large-enough" SSD?

A 64-bit copy of Windows 7 consumes nearly 16 GB. With Office 2010, Photoshop CS5, WinRAR, Adobe Acrobat, Crysis 2, World of Warcraft: Cataclysm, and Call of Duty: Modern Warfare 2 all installed, you're looking at more than what a 90 GB SSD can handle. If you want to enjoy the performance of an SSD without sweating capacity (and not fall back on caching), you should make 120 GB your target instead. 

Regardless of the vendor from which you buy your drive, today's most popular performance-oriented SSDs are powered by controllers from either Intel, Marvell, or SandForce. The first two sit at the heart of Intel's SSD 320 lineup, the SSD 510 family, and Crucial's m4 portfolio (we have a top-to-bottom exploration of the m4 coming up soon). Everything else seems to be driven by SandForce's logic. The company partners with a number of different vendors that leverage its technology, making it relatively easy to set up a roundup of SSDs based on the newer SF-2200 controller.

Keeping It Real

Now, here's the thing. When we review new SSDs, most vendors want to ship us the fastest model available, which is usually in the 240 GB range, with 256 GB of raw NAND flash. Unfortunately, those drives are also prohibitively expensive for most enthusiasts. They're also not representative of the performance offered by smaller drives. The ones most folks end up buying when they shop for SSDs. 

And so we sent out invitations to all of SandForce's partners, seeking 120 GB models that we knew would be more realistic to power users trying to divide up budget between fast processors and capable graphics subsystems. The seven drives in today's roundup represent a response from almost every single one. Notably missing are Kingston, which isn't quite ready with its drive yet, and OWC, which turned down our request for a 120 GB sample.

The drives that remain fall short of the performance specifications presented in OCZ's Vertex 3: Second-Generation SandForce For The Masses. However, there's no question that these 120 GB versions are still super-fast. How, exactly, do five different companies differentiate drives based on the same controller hardware? It all comes down to NAND technology and firmware. Here's what we're working with today:

    I still think a 60 GB SSD is more than enough for the AVERAGE user. Personally, I keep all my games on my hard drive because it is of little consequence whether they launch in 3 seconds or 6 seconds from the hard drive.

    Seriously, who cares?

    How about some information on Win7 and osx boot times : )

    Just reasoning from theoretical read speeds and my own experience with a Patriot Inferno using the Sandforce 1220 controller, the Patriot reads about 2 1/2 to 3 times faster than my 1 TB Seagate Barracuda. So the new Sandforce SSDs will boot Windows 7 approximately 5 to 6 times faster than the most modern hard dives can.

    Until SSD's get closer to $1/gb, I won't be buying these anytime soon. I like the technology, but just can't seem to want to spend $2/gb for these.
    I also agree that 60gb's is a pretty good size for most people, as long as you have a data drive to use for music, movies, etc.

    Right on the button, lunyone!

    Absolutely ANYONE can find a 60 GB SSD for less than $100 and COMPLETELY change the nature of their PC! And it is pretty hard for the average user and reader of Tom's to saturate that 60 GBs using what 99% of us use for games and applications. Toss everything else on the hard drive and you are golden!

    ... i have the OCZ Vertex 3 120Gb for 2 months now... thx 4 the review... now i know, i made the right decision...
  • randomstar
    I have to wonder, does windows Vista really take advantage of SSD correctly or do you have to go to win7?
    Asking, because I pulled a WD Scorpio and repalced it with a OCZ Vertex 2 90 GB. and see almost negligable performance increase, even on a clean load.

    I picked up an ocz agility 3. I run it on a sata II connection, on a nvidia chipset. My benchmark results are very similar to these so my initial worries are for the most part, gone. In the near future, I'll probably give it to my mother though, and opt for a larger vertex 3, maybe max iops version or something. idk. Until I graduate to a sata III connection, the agility is more than agile for my needs.

    Thank you for this article.

    (I just wish I wasn't colorblind, some of those charts gets confusing lol)

    my brother bought a 120gb SSD and so i got his 64gb SSD and teamed it with mine making a raid 0 SSD of 120gb about..which goes smoothly..

    After 1 year of use, with windows ultimate x64, office, cs5, corel suite, loads of documents and way even more programs installed (2-3 favourite games) , i still have 30gb free space.

    So yes i agree, 120gb SSD is fine for a home/power user of windows 7.
  • beetlejuicegr
    Ohh forgot...
    as a pc service proffesional, i installed many many 64gb ssds to point of sales PCs (you know the touch screen PCs used for taking your phone order on your favourite fast food).
    It is the best thing happened to these massively used POS. Heat went off, speed is perfect! Most of these machines use a single file data especially if the interface is made on Access :)
