I propose to discuss the advantages and disadvantages of these discs in comparison with the railway.

access time, read \\ recording speed, the noise characteristics, temperature, form factor, wear resistance, impact resistance, lifespan and of course price.

At the moment, there are models with 80 GB. and most recently appeared on the 160GB model. at a speed of reading \\ record 70 megabytes per second, which can have a serious competitor to the usual magnetic disk, this think that this topic should be discussed and actively.

I'll try later to make a table of advantages \\ shortcomings.
26.02.2007 17:30:00
Cons - price, the volume, the number of write cycles. All the time.
Pros - everything else
26.02.2007 18:39:00
Currently HDD / Flash ~ 1/35 price ratio. I think the commercial value of the SSD will come at a ratio of ~ 1/10. . . 1/5. With falling prices for flash memory every year ~ 80% and the HDD ~ 25% this value IMHO come through at least 3 years. So it is too early to establish such a branch
ZY. Sam looking forward

If tomorrow all the majors dumped at retail such discs at affordable prices, the price of flash modules soar to the level of the year before, which will inevitably affect the prices of the discs themselves. So it is for their mass implementation is not ready to semiconductor industry - it can not provide the required volumes, and will not be able in the near future. It is one thing to issue cards by 1 GB for 15 bucks or 8 GB 90, and another mass of 64-128 GB drives At least 500-600. Flash memory does not grow in the forest

26.02.2007 20:46:00

on a cycle of work, the nanotubes will soon introduce 22 nm process technology. and a minimum volume of 100 GB.

step has been taken, of course, I also think that issued the samples will be very uzkospetsilizirovannoe direction, for example in the military field, but the nemenee can be calculated that even at the moment 80Gb flash memory has a retail price of $ 600, add to this "FREE technology "UDMA integrated in the controller allows us to get 70 megabytes for writing and reading something. . . . SSD drives in deskoptnyh machines is not a myth, but a very near future.

A proizvodstennyh AC I think enough that would satisfy the market, every year the demand for flash cards is growing by approximately 30%, and analysts prozvoditeley many companies are thinking about the trends in sales growth.

About that speech and that seems to be on paper, it is 600 uev, and a year and 300 may, but actually, if major firms run it in a series of massive, the price sharply poidёt up. It is something like a feedback system - the reason depends on the result. If we trace the dynamics of prices of flash memory, it would be an interesting pattern: in the annual cycle, there are 2 peaks: in July and in November, when prices grow by 20-30%, and then drops sharply. What do you think why?
I do not know the exact infoy by date, but if you believe that what they write on this resource ( www. Dramexchange. Com) , the significant expansion of capacities by building new factories, will happen during 2008, therefore expect an increase in volumes production of memory modules with all the favorable consequences can be in 2009. I think more or less mass to penetrate first SSD in laptops (about 30%) in 2010.
In general, I think that the HDD proshuschestvuyut blezhayshie at least 15-20 years, and eventually move into the niche, which is now occupied by streamers or matrix printers - slow, but cheap. And that will come to replace them, I do not even dare to imagine. It can flash may optics can holography, or maybe something more. . . While more chances in flushes, but I think that is not exactly nand

I think vintostroiteli little may prevent SSD-builders. After all, in fact STO - this is a great flash drive, the price of which depends entirely on memory prices. Besides the production of SSD it is much easier and cheaper - do not have any clean rooms, high-precision machine tools, compliance small qlt for mechanics and so on... This can work out a lot of small, on the scale of the industry, businesses. Actually what we see now in the production of flash drives and memory cards. In principle, the only vintostroitelnaya firm that can prevent the development of SSc -.. It's Samsung that is to produce more than half of the entire memory. But for them the production of flash memory is an oil well, which only further zahleschet if STO will mass-produce. So they better put one on your body vintostroitelny branch, what will set itself as a stick in the wheels
Prevent SSD can only deficits in memory and other words of its price, but it's a matter of time. But all these flaws technology associated with the number of write cycles will correct as soon as baks gigabaksy profits.

The company Super Talent Technology has announced a series of SSDs (Solid State Disk, SSD), connected to the PC via interface Serial ATA. Prior to this, in the "arsenal" of the company had a lot of models with IDE connector.

presented "wheels" are available in the form factor of 1, 8 ", 2, 5 'and 3, 5" series includes models with a capacity of 16, 32, 64 and 128 GB Recall that the benefits from the use of such drives several..: . a very low power consumption, high reliability and performance, no noise during operation

complete list of drives Super Talent SSD looks like this:
"SSD16GB18" - 16 GB 1 8-inch SATA SSD
"SSD32GB18" - 32 GB 1 8-inch SATA SSD
"SSD16GB25" - 16 GB 2 5-inch SATA SSD
"SSD32GB25" - 32 GB 2 5-inch SATA SSD
"SSD64GB25" - 64 GB 2 5-inch SATA SSD
"SSD64GB35 "- 64 GB 3, 5-inch SATA SSD
" SSD128G35 "- 128 GB 3, 5-inch SATA SSD

time appearance on the market of new products - April 2007, the price is not yet known.

SanDisk has expanded its offer of SSDs (solid state drive, SSD). The new model of 32 GB is made in the form factor of 2, 5 inches, equipped with interface Serial ATA (SATA) and is designed for laptop computers. We recall two months ago, SanDisk introduced 1, 8-inch SSD for ultraportable notebooks model. Today's novelty is, in fact, is a direct replacement for the 2, 5-inch HDDs used in notebooks, mid-range, that is, models of mass-market segment.

The key advantages of the product manufacturer include high reliability and performance. Regarding the first point, while the average time between failures for the SanDisk SSD is equal to 2 million. Hours, which is about six times greater than that of the currently used hard disks. With picture performance even more gratifying - this indicator SSD more than 100 times greater than hard disk drives. Steady read speed of SanDisk SSD is equal to 67 MB / s, and the input-output operations related to reading a 512-byte random portion may be carried out up to 7000 times per second (IOPS). As a result, according to company estimates, loading Microsoft Windows Vista Enterprise on a laptop equipped with the new drive takes 30 seconds, and the average time to access files is 0, 11 ms. In comparison with conventional notebook hard drive, loads the OS specified within 48 seconds. File access time in this case is 17 ms.

important from the point of view of the users of laptop computers is low power consumption and SanDisk SSD. Compared to hard drives, saving up to 50%, which has a positive effect on the battery life of mobile assistants.

wholesale price of 32-gigabyte, 2, 5-inch drive for notebook manufacturers - $ 350.

with regard to the first point, while the average time between failures for the SanDisk SSD is equal to 2 million. hours, which is about six times greater than that of the currently used hard disks.
As you can see from the operating time, manufacturers are already actively fighting and the price is very real for such disc is even today! SSD exactly will soon go to the masses for the future tverdotelynymi drives.

you understand what the word "record" that before you burn the flash, it is necessary to erase and erase that have flushes per-block, and maybe dig while erasing and writing of one block?
15.03.2007 19:21:00

2 ms, 150 ms
15.03.2007 19:46:00

And now think for:
1. How many times the write speed on the flash is slower than on the HDD:
Input:
3 are recorded on 1KB file, which fall into 3 different blocks of 1 MB on the flash and the HDD.
read speed from a flash and HDD assumed to be 70 mb \\ s, write speed on the HDD 60b = \\ s, seek time 13ms = HDD heads.
Absolutely all real numbers.
algorithm writes to the flash:
1. Read the entire block into a buffer in the computer memory.
2. Save the edited file to the clipboard.
3. Erase the block (1Mb) in flash.
4. Record block from the buffer into a flush.

Povtorit1-4 2 more times.

is easy to calculate that the screw will record these 3 files in about 40ms, because he does not want to erase anything, plus the reading performance of information, where to write the files it is also about stolkozhe, well let just 100ms. For flush
consider yourself, but I'm not thinking I would say that it would be 3 times slower.
way blocks are now longer, the greater the total amount of the chip, the greater the size of one block.
15.03.2007 22:24:00

Voobscheto for erasing the whole point is not considered, 2ms. it is very small. With the rest I can not argue because I do not know before erasing all blocks are read simultaneously or one by one, if the one you are right, if at the same time it is not.
16.03.2007 8:42:00

if there is no time.
A podumate themselves. Or look for the characteristics of solid-state drives for recording.
recently slipped in the news about the tests of SSDs. More
think for the cost of 1 GB. In HDD ~ 10rubley \\ GB (WD 2500) while the flash drive?
16.03.2007 9:34:00

A 32 gig for $ 350 and is not a problem. Take 4 CompactFlash (aka IDE) 8 G. Take the simplest PCI IDE-Raid on 4 discs for $ 10, stick through adapters, build raid-0 and the lead mines. The speed limit will only PCI. Price issue 330-400 + light gemorchik.
PS: IDE has its word to say
16.03.2007 9:51:00

IDE has its word to say

Not much, but a little less than 2 times, moreover, the speed does not drop linearly. Almost half the rate of decrease volume barely noticeable.

and for random access in general tend to zero,
Well, that's just stupidity. Just, random recording on hard disk is much faster than random reads from-behind cache.

And mention MTBF when using flash is not serious. This time may be true, if the flush is simply connected to the power supply.
necessary to bring the number of write cycles. If you hold back, so not everything is so beautiful, like paint.


Et vryatli 133 MB \\ s already limits the speed of RAID0 of 2 disks.

Yeah. Moreover, these restrictions also on all bus devices at once. So that the idea of ​​PCI-Ex. . . fuck knows how many

1. Read the entire block into a buffer in the computer memory.
2. Save the edited file to the clipboard.
3. Erase the block (1Mb) in flash.
4. Record block from the buffer into a flush.

No wheels. The data do not chase back and forth. In USB1 capacity of about 800 KB / s, and write it fits.

Inside the chip is quite real, but not in the computer memory.
16.03.2007 19:23:00

No wheels. The data do not chase back and forth. In USB1 capacity of about 800 KB / s, and write it fits.
Study, study and study again, then a ride.
AGAIN syllables:
a) To record in a flush, all the bits in the write place should be able to 1. (FFH) t. E.
erased b) the flash can not erase a byte, only the unit entirely.
c) Before erasing the block you want to keep available in it useful information.

USB1 and USB2 speed look for yourself.


It does not limit the IDE and PCI.
And what is the IDE faster 133 MB \\ s?

Not much, but a little less than 2 times, moreover, the speed drops linearly. Almost half the volume reduction rate barely noticeable

Yet we can say this: From the beginning of the HDD within the available capacity of solid-state drives HDD constant reading speed \\ recording.

Maybe
combined. But if it were squeezed, the rate would be limited to the interface and so on. Features a computer operation. But it is not - there is still room to grow, at times.
However by analogy. Theoretically, it would be possible to read / write on all sides HDD pancakes at once. Then the rate was increased to almost proportionally to the stop in the interface and overhead costs, and even with a win at the time of positioning the heads on track. However, in reality it is not. Eg. 7200. 10 250 from 3 sides and it is 750 with 8 give almost identical 75-78 MB / s, which is far from the theoretical limit of the SATA-2 ~ 300 (and even a little big brake). These grow from 75 plotosti * turns to one side. They're 4 pieces in a raid-5 reading give a clear almost tripling. The raid 0 might be given and the quadrupling of just dumb to yourself to check
