Read Transfer Performance

Read Transfer Performance

The throughput of 115 MB/s is a new record. It is especially interesting to see that it only drops to a minimum of 112 MB/s, while all mechanical hard drives deliver slower data transfer once you move from the faster outer sectors to the inner sectors of the rotating platters. A Western Digital VelociRaptor provides slightly better maximum transfer rates, but its minimum transfer speed drops to only 65 MB/s. While this is still a great result, it cannot compare to the flash SSDs.
Write Transfer Performance

A write speed of 120 MB/s is a result that might have been stimulated by the Adaptec controller’s cache memory. However, the data transfer diagram clearly shows that this drive maintains this high throughput.
PCMark05 Application Performance

File write performance competes with the throughput of the WD VelociRaptor, which is excellent for a flash-based hard drive. However, the Memoright drive is also 10x more expensive than the VelociRaptor.

Obviously, Mtron’s Flash SSD still is quicker when it comes to starting Windows XP. Yet, Memoright is the second fastest and more than twice as fast as any other mechanical hard drive.

The key here is that SSDs are optimum for big retailers & enthusiasts, because of the lower failure rate compared to mechanical drives means less hardware failure and RMA and tech support calls. For us, its performance based. Dell and others will flock to these when the pricepoint hits home, and as soon as they jump on, drives will sell in such volume that new plants will have to be made and we'll need SATA-1000 before long.
Anyone whose been in the industry professionally and watched tech roll out over the years can see the writing on the wall, SSDs will dominate at least the "bootdrive" sector within two years. It might take longer to ramp up capacity for the "data" drives for home users, but its coming, and every process shrink to a smaller fab makes capacity go up exponentially.
The ONLY, and I mean only, area where ssd drives will get consumer exposure will be in the laptop sector, simply because of the size/power requirements. For that to happen, ssd prices will need to fall "tenfold" and conventional hard drives will need to die out, which won't happen any time soon.
Desktops will will continue to use conventional hard disks for at least the next 5-10 years as they will go down in price and increase in capacities. Sata III 6gbps and newer pmr technologies will keep the traditional hard drive alive for a long time yet.
Servers may transition into a hybrid environment with both ssd and conventional drives, but with the cost of raid now so affordable (controllers incorporated into chipsets) and the fact that traditional fast (velociraptor) and beefy (terabyte) drives will ALWAYS be cheaper than the ssd variants - it's going to be a hard sell.
I'm not saying ssd is bad, but for those who don't have 5-digit monthly income, it is merely a toy for the rich. Sure, prices will eventually fall, but until you can sell the technology for 25 cents/gig or better, it will remain insignificant.
| geralt : SSDs have weakness in random writes and reads. Unfortunately this was not tested here. |
A mix of SSDs and HDDs will probably be the best solution for a long time. They each have their strengths depending on usage patterns. As soon as SSDs become more economical, mixed setups will quickly become the norm. I would have a couple of SSDs in a RAID 0 config to boot on and load applications off of, but I would have a some HDDs in a RAID setup for mass storage.
I really can't wait to build my next system. Gone is the day where I reuse a harddrive on a new build, and the new computer seems only as fast as the old one due to the HDD bottleneck.
As someone else commented on I am HORRIBLY disappointed that Tom's didn't test random writes and reads. If they actually didn't that is, I haven't finished the article but wanted to respond to the "clown" guy. I've noticed a lot of stuff like that with tech sites and it makes me wonder what kind of enticements these guys have to talk up a given product. Please do a follow up with random read&write tests.
as fas as the size goes. there is only a small amount of XP/Vista that needs benefits from super fast access. Your application and it's data are usually the best canidates for super fast storage.
/And yes show us the random access tests since you do talk about OS storage.
Give me a break. Maybe years from now but that's not exactly news. Anyway, when it finally happens this specific model will not be the one to do it. It may end up being an entirely different technology that ends the HDD if SSD's don't drop in price fast enough.
Drop the sensationalism, start labeling both the X and Y axis of your graphs like professionals, and try to regain some journalistic integrity.
Toms is going downhill fast.
In fact, even if the 32gb ssd drive was $300, I would still have a hard time justifying the cost for such little space. 128GB at $300-$500 and I MAY think about buying one or more of these.

This has about the same marketing hype as ddr3 compared to ddr2.
I could care less about access times.
I am not paying their prices for a 32gig "SSD".
It is just not worth the money.
