here is the official "lie" from samsung ... :mad:
maybe mr. bae forgot to tell witch YEAR?!
(this email is from 02-11-2009)

The cache of 256GB SSDs is 128MB.

256GB SSDs will be available for general customers since March.

Please contact our local Branch Office and discuss in detail regarding support.

Deep apology for the inconvenience.

Hi,

I am due to receive my 17" 2.66 MBP with 256GB SSD early this week. I've been reading all the comments on the Toshiba SSD drive I am likely to receive and wanted to be able to help you fill out this table (for my own interest too). Can you tell me how I can help you do this. ie. What software to run, setup conditions etc.

Although I am after the additional speed I decide on a SSD for data safety purposes above anything else - I have dropped many many laptops during my travels. I realize I still have to backup though.

Mc

PS. This is my first Mac (apart from usage of other peoples) so be gentle with me - although I am generally computer proficient. As an aside this switch is HUGE for me. :eek:

The data I've been putting on the table is the manufacturer claimed speeds and specs, not the results of any tests. A test-based chart might offer more real-word information, I just thought it might be a bit much to get into. Thanks though.

One way you can help me is by sending me links to information regarding different SSDs so I can post it.
 
today i spoke to mr. bae (samsung germany), he told me that ALL samsung 256gb ssd's before april '09 are pre-models and therefore not "real" available ..
(and are not on the release standards as they will be from april '09 on ...) ;)

Yes, she told me the same thing. I also got them to send me a SPEC sheet, but Im still waiting on that one. Below is what she told me:

Firdst e-mail:
Dear Mr. [censor]*********[/censor],

Samsung is now under sampling stage for this new product,and I think it can get started its mass production from the May..
PM800 stands for MLC NAND based SSD products.
Let me give you an preliminary data sheet of 256GB as soon as possible.


Sasch, woould you please send the SPEC. to Mr.[censor]******[/censor]?

Second email:
Dear Mr. [censor]******[/censor],

Please contact Mr. Dieter Graf who works at Samsung Semiconductor Vienna office, and he can help you for the SSD.
The 256GB SSD samples are available from the end of March, but it should be followed sample ordering procedure.



Best Regards,

Shane(Soo Han) Bae

Big price drop on 120GB Vertex.

I noticed you dropped the Max Read/Write columns. Are the speeds you have now listed the theoretical maximum possible or the continuous actual speed?

I just used whatever speed the manufacturer gives. About half gave sequential and half gave max speed, so I just put them all under read/write. I wish there was a better way. If anyone has any input, please let me know.

Updated for Vertex 60GB price drop.
 
Thanks

Great idea and thanks for posting. I will check it often as I'm considering an SSD drive. It will help me narrow down what I need.

What they use in current unibody macbook pro samsung 256gb? Which one is best SSD.

What they use in current unibody macbook pro? Which one is best SSD.

Im looking to buy asap but i wanted to make sure that this extra money for samsung 256gb hdd is worth it since seagate just came out with 500gb / 7200rpm hard drive which is beating most of these ssd to dust.

Poor "random write performance" is ailing most of these drive.

Whats/when is the next *major* SSD hd coming up?
 
Tubbymac posted a very informative link on the SSD topic. Here is a rather long, but very informative SSD report.

http://www.anandtech.com/storage/showdoc.aspx?i=3531&p=3

I read the entire thing and I think if your looking to spend $500 to $1000 bucks you should consider reading it. The marketing guys at the various companies all want us, the consumer to buy into these Read/Write speeds. However that is some/most of these claims is bogus BS which is just to get you to buy their SSD drive.

Once you read about the latency and performance decay some of these drives experience you may reconsider how you think about SSD's. I know some of it maybe more technical information than you want to know, but just because drive a is 250 read/150 write does not mean it will out perform a 150 read/70 write speed drive in real world use.

I highly recommend this read to anyone in the market for a SSD drive. I'm glad Tubbymac posted the link, probably just saved me and alot of people who read it headaches and disapointment from buying only based on Read/Write speed.
 
Good work emt1!

I suggest you put in also seek times, about which Anandtech elaborates in the post above.
And in empty price tables you might note which Mac it was spotted in.

If you can find me that information for a significant portion of the drives listed, I'll put it in.
 
Updated with several pretty significant prices drops. Wow, these are getting cheaper by the day!
 
I read an article suggested the OCZ Vertex was a solid buy, more bang for your buck, but the best was the Intel 25M. The writer also said most other SSD's were not worth it though.

He said something like most other SSD's use the JMicron chip which blows and their write speed can fall to below that of a decent 5400RPM HDD when used for a month in the real world.

Write speed is crucial since the OS constantly writes to the drive (small amounts of data, but increased latency in write speed affects overall drive performance).

I say wait another 6 months to a year and SSD's will work out some more of the kinks AND be cheaper.

But I sure would love an SSD in my next computer, which I will be buying soon.

Now, you have OCZ and Patriot (obviously Intel). Patriot came out with some pretty good SSDs write/read wise. I want to know if they have a cache though.

Also, I'm not surprised at the price drops. Its simple supply and demand. Now we have more people wanting to cash in the SSD market, so price lowers...

I am also waiting a couple of months before I buy my SSD. I'll probably end up buying it in October.

I've not been able to find a high speed ExpressCard/34 SSD.

So - is it possible to purchase one of the 2.5" high performance SSD, put it a standard external SATA enclosure, and connect it through an ExpressCard/34 slot?

I want the larger HDD capacity in the MBP but the speed of SSD / SATA for HD video playback.

I've ordered one of these.

I've read much about the small file write problem (stuttering). My plan for this drive is to use it on my work laptop (Windows XP) and work in a Virtual PC from it. I suspect that initially, I will get a very good increase in performance. Whenever the performance drops off too much, I'll simply run a low-level format and start from fresh again.

At this point, I wouldn't entertain the idea of using one as my primary boot partition.

It happens each SSD. Let's hope they come up with a "fix" to it.

This is why I'm only using it as a "working" disk - my main hard drive is the old spinning plates....

I've been using it today and benchmarking/experience shows there's an approximate 20%-30% speed increase in disk access. I've not had any stuttering as yet.

Why are SLC SSD's so much more costly? And will they always be limited to <64GB's?

/SSD nub
Click to expand...

Hi SSD nub ;)
Few things :
SLC uses twice the cells /Gb => twice the price ...
This bars it from being used for storage, hence they positioned as a fastest, unhindered access/transaction devices - which they are.

So I think they'll get bigger over time, but only after they get lot cheaper.
On a contrary MLCs will progress faster in capacities, as they already positioned as a primary boot drives, not just app-specific drives.

I personally will get Intel's MLC, nex gen, around summer/fall'09.
And I don't think I'm realistically going to notice any difference in write performance.

Searching (Spotlight, SQL, etc) is most critical application for me, I rarely shut down apps or reboot.
 
Updated with a few minor price drops and included a new row for the upcoming Corsair SSD, which is making me drool!
