As mentioned elsewhere I have one ordered and got shipping notice today, so there's a fair chance I'll get to play with it on the weekend.

On spec, it is essentially half of a X25-M 80GB drive for about half the price. I'm using this article as a reference for its performance vs the X25-M 80GB.

Sequential read: 184 vs 256 MB/s. The 80Gb is a bit faster, but not double, as I guess the SATA interface is limiting.
Sequential write: 42 vs 82 MB/s. This is a general weakness of Intel SSDs anyway, and halving it here doesn't help. You wouldn't want to copy big files too often to this...
Random write: 35 vs 39 MB/s. This is where I think the drive will make the difference.This blows away any conventional magnetic device.
Random read: 61 vs 64 MB/s. Again no great difference here between the drives, and they should be magnitudes faster than rotating drives.

I wont list all the rest, but their more scenario based benchmarks generally show a narrow performance difference between the two SSDs.

My usage will be in an Acer netbook, which came with a conventional 120GB SATA hard disk, on which I use Vista as the main OS for a few reasons: XP power management support sucks, I had a spare Vista licence lying around, and Win7 was still in beta phase at the time. Vista responsiveness isn't bad once it had booted, although it still seems to be doing a lot of disk access for no apparent reason at times. The Atom CPU isn't the fastest, but outside of photoshop plugins it is fast enough. I had upgraded the ram to 1.5GB which is adequate as I run it with minimal additional processes. That leaves the old fashioned disk as the remaining bottleneck.

When it arrives, I'll be sure to run before and after benchmarks of some sort to show what change it makes.

What will I do with the hard disk? I'll probably stick it in my PS3 as the original 60GB fills rather quickly with game "installs".

You can also get a Scythe Kamazo 2 SATA enclosure, which basically transforms your old drive into a portable USB harddrive. The best thing is it's price, they go for around 6 euros here :lol:

I'll probably be buying the 80 GB X25-M G2 around the start of next month (paycheck woo!), so I will, too, report my findings.

I already have a 40GB PATA 2.5 inch USB drive. I find I never use it though, as flash drives are cheap and much smaller.

In a way I hope the SSD wont speed up the netbook too much, else it might make my main desktop feel too slow and I'll be tempted to upgrade that too.

Damn that was fast delivery. Ordered about 2pm yesterday on ebay. Just picked it up from work warehouse on way back from lunch. It might help that the courier depot is around the corner from here...

The retail box is really tiny. I guess I shouldn't be surprised, but it's about the size of a 4 or so CD jewel cases stacked.

Guess I'll do the "before" benchmarks now before I try to swap over tonight.

You'll notice the difference in load and startup times.


Nothing like loading CSS before anyone else and spawn kill the other players without them knowing. :twisted:

Not on a netbook with atom processor and integrated graphics I wont :D

Giving the OS an update now, gotta uninstall unnecessary stuff to reduce the amount to copy, then run the "before" benchmarks.

So far I have planned:
System power consumption (idle desktop)
Boot time (after POST to logon screen)
Crystalmark
Atto
HDTach
The built windows experience subscore.

Anything else I've forgotten?

Still setting up the system...

I don't see any relevance in running 3DMark Vantage, isn't it more a graphical/CPU test? Plus the trial version seems crippled to run once only. Also, power usage was more for a comparison of the two drives. Maybe disk under load is worth a look too, but I'm not sure how best to exercise that. The power usage of the rest should be constant.

Maybe the swap file being faster will help. I dunno.

Also, if you are going from 32 bits to 64 you should notice a cpu performance increase.

I'm not changing the OS, and couldn't anyway since Atom doesn't do 64.

Still waiting for a defrag to finish before I take the baseline measurements...

Ok, I'm not finishing this tonight.

Some "before" figures to get the ball rolling.

Power consumption, battery full, mains powered, USB mouse and wired network connected:
Desktop idle 11W
Atto running: 16W
Boot time: 32s
Windows disk subscore: 5.4

Crystalmark, Atto and HDtach screenshots will follow when I have the "after" results too. I need to find a way to do a disk transfer copy, - anyone know of free utilities that can do that easily? Want to avoid doing a clean reinstall.

The results are in!

To recap, an Acer Aspire One ZG5 netbook was used. It has been upgraded to 1.5GB of ram previously and has Windows Vista Home Premium 32-bit installed. At the time of testing it had a wired network connection and a USB mouse connected. Mains powered with battery fully charged. The hard disk had a defrag run before testing.

The original hard disk is a Seagate Momentus 5400.4 120 GB drive.
I copied the partition over to the Intel X25-V 50 GB SSD and after a quick repair to get it bootable again, repeated the benchmarks.

When the SSD was installed, I ran the trim tool between each benchmark run even though it shouldn't be necessary. Even at this stage, SMART reports I've only done 33GB of writes to the drive. I've almost used 0.01% of the drive life already!

Values listed in order of "before" and "after".

Power consumption at idle desktop: 11W vs 12W. It went up! I was hoping the SSD would be able to employ smarter power saving compared to an idle spinning disk. I guess not.

Windows Vista boot from post screen disappearance to logon screen background showing. 32s vs 29s. Around 10% improvement. Not really noticeable. I was hoping for a bit more there.

Windows Experience Index disk score: 5.4 vs 5.9 - not sure if this means anything really... yes, it went up.

Onto the synthetic benchmarks:

Image
This shows a typical mechanical hard disk response, with a higher transfer rate of over 65MB/s at the start, dropping off under 35 MB/s at the end, averaging 54 MB/s. Random access an unremarkable 15.7ms.

Image
The SSD does what it is supposed to. Quite consistent speeds through the whole range, averaging 104 MB/s. Almost double the sustained read speed! Random access 0.2ms - a huge improvement again.

Image Image
The CrystalDiskMark shows a similar pattern, although also giving us write information. A little caution needs to be applied to the hard disk results, since it is not known where on the disk it might have been reading, so the sequential rates may be anywhere in the range shown previously by HDTach.

As I saw in review benchmarks, here we see the Intel SSD's weakness, sustained write speed is about 75% of the indicated hard disk rate. But it easily beats it in all other cases. Faster reads and writes, particularly as the side and randomness increases.

Image Image
Here are the Atto results, run with default settings. Do note the horizontal scale is different. This shows a similar result to earlier. The hard disk ramps up to its limit which is the same for both reads and writes. The SSD again shows lower absolute maximum write speed, but at smaller transfer sizes it retains the lead, as it does in any read condition.

I haven't used it much yet. Is it faster? Yes, maybe. Is it "wow" faster? No. Maybe a SSD aware OS like Win7 will help, so I think I might try installing that for a test spin.

Edit: Win7 benchmarks were near enough the same as on Vista. The system idle power consumption again dropped to 11W. Boot time was over 41 seconds. Don't know why it would take so long for a patched up fresh install... back to Vista I go.
