Could An SSD Be The Best Upgrade For Your Old PC?

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.

Benchmark Results: Random Read/Write

Thanks to solid-state technology's responsiveness, the difference between SSDs and mechanical storage is even larger in random 512 KB transfers. Let's have a look at what happens when we use 4 KB reads and writes, rather than 512 KB pieces of data.

The SSD is roughly 40x faster than the hard drives when it comes to 4 KB random read operations, achieving 14-18 MB/s instead of 0.5 MB/s. This is the case for individual I/O requests. We expect that when you start to pile on pending commands, the situation becomes even more pronounced.

Now we’re seeing 130x to 210x more performance from the SSDs. The hard drives still deliver between 0.6 and 0.9 MB/s of effective throughput, while the SSDs move 130 MB/s in our 4 KB random read test. When it comes to writes the gap closes a bit. However, it's still the difference between night and day: 0.6-1.1 MB/s for the hard drives versus 75 MB/s on the SSD.

    SSD is just too exaggerated, yes it is faster than HDD and may be more reliable but that doesn't justify its price.

    Waiting until it is price gets reasonable.

    The conclusions we're drawing relate to the mainstream folks trying to get more life from an already-aging box

    since its for mainstream, i would have liked a subjective test where some 'average' folks, doing 'average' tasks, would use the machines with/without SSD's, and rate the perceived speed on a scale of 1=10.
    those should have been included as well. most people "feel" the speed, rather than benchmark it.

  • Can you run gaming/photoshop/actual applications instead of benchmarks?

  • Please do a test with a Pentium 3 + KingSpec PATA SSD.
    I'm very curious about the results. My Dell Lat C400 is chugging along just fine on Windows 7 but I believe a SSD would greatly improve performance.

  • I recently bought a Transcend 32GB SSD to be my Boot Drive in my 5+yr old system- Athlon64 3200+ (Venice) S939 , Gigabyte GA-K8N51PVMT-9 ( Geforce 6150), 2 Gb DDR400, WIN7 SP1.
    I do not see that the SATA controller mentions AHCI in the device manager tab, however when I run the TRIM check commnand through CMD, it returns a "enabled" reply. Also,have made the necessary registry changes to ensure that AHCI is enabled. There is however no option in the MB bios to set AHCI.

    So is my drive configured with TRIM enabled or not?

  • buxx I wish I knew the answer to your question too. I have a Dell Dimension XPS600 which I would love to put an SSD into, just as this article suggests. However I can't find any mention of AHCI in the BIOS, manuals or anywhere on the web. Hard to say if it's present, but you would guess not, if they don't mention it... right?

    I think that if you're trying to get more legs out of an older system, a SSD is definitely a great way to do that. Especially with laptops from the past four years -- a Core 2 Duo processor in a laptop still isn't fast, but a decent SSD will make it feel like a new system (at least in my experience) and then some. I think trying to make your Pentium 4 system better with some solid state storage is a lost cause however.

    How much is reasonable? A 64GB Crucial M4 is $105... that's pretty damn reasonable to me. For that kind of money you could get a low-end mobo, an Athlon X4, or 16GB of DDR3. Upgrades don't get much more reasonable than that. But if you already have a decent, if older system, installing an SSD will make it feel like a brand new system should for the least amount of money.

    I installed an SSD in my netbook with an 1.6ghz atom processor and it really sped things up. The computer went from unusable to fine for casual usage.

    Predictable outcome but informative article non the less. My only concern is that since you talked about mainstream pc, i didn't see any amd equipped system. This is not about AMD vs. Intel it's about storage controller performance. Thinking back, most builds I did back in the 2004 - 2006 time frame where based off nvidia + amd. This article would have painted a more complete picture if it had taken into consideration the other half of the pc landscape. In theory i guess you can argue that yes, if it is AHCI enabled then it "should" be the same outcome as the ICH scenario ... but is it for a fact?

    Maybe Tom's can do double blind subjective tests like they do in Mythbusters.

    Spend 10 mins doing office/internet stuff on each config without knowing which is which and rank them by speed subjectively.
