Cost / Performance Shootout at the SSD Corral

"It’s no secret that replacing your notebook’s hard drive with a solid state disk can dramatically transform your computing experience. With even last year’s SSDs, tasks such as opening large files or starting bulky applications take mere moments to complete. And if you own a notebook powered by one of Intel’s 2nd Generation Core Series CPUs, you’re in for a whole new world of fast, courtesy of SATA III, a high-speed interface Intel included in its new chipsets starting in 2011."

One of the secrets of enhancing computer performance is to remove bottlenecks, and a few years ago the biggest (and cheapest) way to gain added performance was to add memory. Today, memory seems to be no longer an issue, so we've moved on to the venerable hard drive as the point where data flow slows down. As SSD prices drop, expect to see the hard drive start to go the way of other past drives, and be replaced all or in part by solid state drives. We already are starting to see hybrid (multi-drive) systems, where the boot (OS and programs) drive is an SSD, and day-to-day data is still stored on a spinning drive.

This review tests SATA III SSDs from Samsung, Intel, OCZ and Patriot, and they also do an interesting comparison on cost per gigabyte, ranging from $1.53 (OCZ 240GB) to $2.31 (Intel 120GB). Retail prices are expected to be lower. Their comparison hard drive was a 500GB 7,200rpm model, but at a significantly lower cost per GB. The tests are interesting, and the SSDs perform as expected, with Samsung's 830 winning the shootout (cost today $229 for 128GB and $429 for 256GB).

Please note that these performance tests were done on laptops with Intel's current chipsets (supporting SATA III). Older systems will not see this performance.

Is Upgrading Your Old Computer With an SSD Worth It?

"It's a foregone conclusion that SSDs are must-haves in performance-oriented PCs, but our testing reveals that solid-state drives are reasonable upgrades in older mainstream machines, too. We build three old boxes to gauge the impact of an SSD on each."

There are only a few Web sites out there that I trust to tackle thorny questions with the scientific rigour that would make a molecular biologist proud, and Tom's Hardware is one of those sites. They post a fascinating question: is it worth it to put an SSD in an old computer? They reach all the way back to a typical system from 2005, equipped with a 300 GB Samsung hard drive that benchmarked at 54 Mbps, and move forward from there to several newer generations. Their conclusions? SSDs rock performance, even on an older system. The catch though is the price tag; if you need a lot of storage, it starts to make less sense to put an expensive SSD in an older system. One option is to use a smaller, less expensive SSD for the boot drive, then use a large hard drive for mass storage.

Personally, after years of multi-drive, multi-partition setups, I've enjoyed the simplified approach of a single partition, single drive setup on most of my PCs and have resisted going to an SSD until the price on 200+ GB drives comes down. I might re-evaluate that on my next build...we'll see.

Have you installed an SSD in an older computer? Was the performance increase noticeable?

New And Improved X25-M For Your Solid State Pleasure

"While Intel is sampling 25nm MLC NAND today it's unclear whether or not we'll see drives available this year. I've heard that there's still a lot of tuning that needs to be done on the 25nm process before we get to production quality NAND. The third generation drives will be available somewhere in the Q4 2010 - Q1 2011 timeframe in capacities ranging from 40GB (X25-V) all the way up to 600GB."

Wait, did they say 600GB SSD? Is it true that SSDs might just start reaching similar capacities as traditional hard drives? Yes, you can get hard drives that hit 2TB, but for most people, they usually end up with something around 320-500GB with a new computer. One still expects a premium for SSD, but with these larger capacities, and hopefully, increased popularity, we might see some economies of scale going on and making an SSD a more standard purchase for a computer. Even if these new fangled SSDs become more cost effective, I would probably stick with traditional hard drives for storage or archival purposes. At least until 600GB becomes 2TB.
