First Thoughts
We think Solid State Drives have an excellent future ahead of them. We are in the early stages of testing drives designed for the more performance oriented consumer market under an operating system (Vista) designed for them. However, we are still impressed with the overall performance of the Super Talent SSD16GB25/25M Flash Drive considering its design limitations for the target commercial and industrial markets.
Our limited testing shows both the strengths and weaknesses of this particular drive. Considering the read and write speeds are limited to around 25 MB/sec, the drive was forced to rely upon its superior access and random read rates to generate very competitive scores in our gaming and Windows XP operating system tests. However, we do see one of the major weaknesses of this drive being tested in a consumer centric test such as encoding where the write performance was up to four times slower than the hard disk. We expect these results to improve greatly with the consumer based drives, especially under Vista. In the meantime, the Super Talent SSD16GB25/25M is perfectly suited for its commercial or industrial target markets.
For now, the strengths of the technology behind Solid State Drives are significant for the portable market and eventually could be for the desktop market in specialized uses such as general office machines or portable workstations. The failure rates of the drive should be significantly lower since the drive has no moving parts; it can withstand extreme vibration and shock rates, and is designed for a wide variety of environmental conditions. There are other advantages as well.
Unlike the typical hard drive which has read access times in the 11ms range, most SSD products have access times less than a 1ms with the newer consumer drives being around .12ms at this time. This extremely low latency can significantly improve system resume times and random file access speeds when compared to a hard drive. A hard drive requires a motor, bearings, and moving head components that result in additional heat, power usage, and noise when compared to a SSD. Since the SSD does not have any moving parts it generates less heat, uses up to 80% less power, and is totally silent. Other benefits include improved data integrity, especially during power failures, power surges, or physical shock to the drive. The performance of the drive is fixed and remains stable over a long period of time unlike a hard drive that is subject to file fragmentation and slower access rates over time as the drive is filled up.
Of course, with strengths come weaknesses. The major weakness at this time is the cost of SSD products. The average cost at this time is $17 per GB of storage compared to as little as $0.25 per GB for hard drives. Also, overall performance of the SSD is dependent upon the NAND memory utilized and more importantly, the flash controller design at this juncture. We are just now seeing flash controllers and supporting software designs that can offer similar performance to a typical 7200rpm hard drive in most applications. This is one area that we expect to see improve significantly and quickly over the next nine months based upon our discussions with the manufacturers.
These weaknesses will diminish over time, especially with NAND memory decreasing in price by 40% per year based on current averages. We doubt the SSD product will make significant headway into the desktop market over the next three years due to the continued explosion of storage space requirements for digital entertainment. However, we do see it becoming a relatively significant part of the portable market over the same time period along with exceptionally fast double digit growth into the commercial and industrial markets.
We want to thank Super Talent again for providing our first benchmark-stable SSD sample and we look forward to their entry into the consumer market later this year. Until then, if you are a road warrior who is constantly afraid of losing data and can live with limited capacities, you might want to take a look at the consumer SSD products. And for those who are bound to ask, we only had a single drive for testing so we were unable to perform any RAID tests at this time, not to mention that definitely isn't the target market of this particular SSD. We hope to take a look at RAID performance of the consumer SSDs in the future, though the cost of such a configuration is likely to be prohibitive to all but the most affluent of users.

Your post wreaks of arrogance, assuming that everyone uses a computer just as you do.For heavy gamers who also want to encode files there is no perfect solution currently. If you put a 4 disk SSD raid array together it would likely be faster than regular hard drives in its transfer rate and its seek times are faster too. Thus its faster for games and faster for encoding files.
Sure, it's 2000 bucks today... but within 6 months I guarantee you will be able to get 4 ssd's for 1000 or less. Maybe not 16GB each but 4 8gb disks is plenty.
Plus some people don't care about cost, they care about speed. If you care about cost you arn't buying even 1 of these. These are meant for the power user... and a power user would raid these things if it drastically increased performance. We don't know if it does though because there are no tests of it.

Um... there are RAID 0/1 SSD solutions out there. People that review these SSD's should open them up and check what's on the board.Really, you need to know what type of flash and the controller(s) are used in order to understand the drive. It could be using MLC flash that is used in consumer USB pen drives or SD cards. It's cheaper than the SLC, but carries a 5K or 10K write/erase cycle limit per block. SLC is up to 100K.
Still, 100K*16GB gets you about 2 years with this drive if you write 25MB/s straight for 2 years. Wearing out is not a problem that HDD can avoid. The mechanical parts, especially the spindle, of your HDD has a life span. You probably don't write 25MB/s for 60*60*24*365=3,153,600 s/year. If you did, I think your drive would probably not last as long as you think it would. I am sorry, people in the embedded systems market spend the money on flash SSDs because the data is safer than HDDs. Less moving parts vs. no moving parts.
There are also companies that make SD/CF RAID solutions. Let's not get upset because this is a embedded systems solution that is being shifted into the consumer market. We should try to really understand what is being done rather than shoot off speculations.

Totally agree. In some cases the environment cannot use mechanical HD because of the temperature or altitude, or high shock. There is no choice but to use flash.For consumer, the main advantage is power saving, heat, and noise. So there is no advantage for desktop yet, but for ultra portable laptop it is good. If you want performance, you have to pay, and you probably won't be using a large one because you will be optimizing your application (i.e. a database server with 8GB of data with mainly read cycles, and has to be fast) with lots of ram and dedicated processors to begin with. It targets people that uses laptop in remote location that battery life and portability means everything, but they don't waste their battery playing solitary or mp3s, but take survey with equipments, mobile registration offices for emergency response, word processing on a 12 hr flight, military/police setting up check points, etc. They would rather buy more expensive laptops than hauling a diesel generator around.
Just like porn, if you don't get it, it is not for you.

Why were there no Web server or Database benchmarks to show off where SSDs really shine?dm0r - Monday, May 7, 2007 - link
Obviously the first SSD will be more weak in performance agains traditionals Hard Drives.SSD will be improved a lot because its a very recent tecnology, but this drives are a exelent choice for laptops and UMPC's because of its low power consuption, generates low heat and makes no noise, thanks to literally abandon mechanics.Good review Gary!

Actually, these are not the first SSD drives, and some of the first were actually much faster.SSD has been around a lot longer than people think, this are just 'consumer greade', in that they support consumer grade interfaces. Besides all that, there are people such as myself, who do not even consider NAND drives SSD to begin with. In our world, SSD uses static ram, that is much faster, and capable of handling much faster transfers, and do not suffer from this read / write cycle MTBF issue (per se). These types of SSD's however, would not retain any data after the power is turned off, and would require a battery (or some form of electrical current) to do so. So, in this one respect, they are inferior, but superior in most other aspects.

What's EDD?
tirouspsss - Monday, May 7, 2007 - link
the article doesnt surprise me in terms of performance, dunno why but for some reason i had this inclination that ssds werent going to be all that (at least for now).. & the 100K write/read cycle has always bothered me - i just dont trust it.For JW:
"Besides, with the rate of progress it's likely that in the future SSDs will get replaced every couple of years just like today's HDDs."
what do u mean BESIDES??? this ISNT a good thing. werent u saying the ssd is good for 10yrs etc? so y should they get replaced so quick then? plus its bad for the environment, is it not?
Chriz - Monday, May 7, 2007 - link
I think Jared meant that for consumers using SSDs, they would still replace them every couple years just like HDD's because newer ones would be larger and better performance.JarredWalton - Monday, May 7, 2007 - link
Yup. I worked at a large corporation where we had a million dollar RAID setup for the main servers. Some huge box with 72 15K SCSI drives in it. After about four years, every old drive in there (which was running fine) was yanked out and replaced. Why? Because the new drives were faster, even with RAID 5 + hot spare there was concern that multiple drive failures would results in a loss of data, and for a location that generates something like several million dollars worth of product movement every day they couldn't risk any loss of data. So they upgraded all the old drives to new drives just to be safe, and the new drives were also a bit faster. For that type of market, the replacement costs of hardware are nothing compared to the potential for lost revenue.
