Hi again, SSD experts

I have another question perhaps already answered on this thread, so excuse me in advance (this thread is very huge to search for information).

The write cycle endurance of the current SSDs is unknown for me. I've read that current Flash SSD's have, at least, 1 million write cycles per cell, but the exact number for each manufacturer is also unknown.

Well, can you estimate the average life (in years) of an standard SSD? I plan to use the SSD in the same manner as a traditional hard disk (with heavy usage), installing applications, encoding video (hence creating/deleting several files too), and so on. I don't know if this is recommended or may be dangerous, but I want to configure a laptop with a SSD as the primary hard drive and a hard disk as the second one.

Should I worry about this issue? Can the Samsung/Intel SSDs last at least for 6-7 years?

Thank you

 

Can Intel x18-m G1s get TRIM support?

 

HiddenUser it depends on the brand. Multi Layer Cell (MLC) flash can be erased 10,000 times per cell and Single Layer Cell (SLC) can be erased 100,000 times per cell. A single cell is 1bit for SLC and 2bits for MLC. 8bits make 1byte and there's 4KBytes per flash page, and 512KBytes per flash block.

Intel says if you wrote 20GB/day on their 80GB X25-M Generation2 it will take more than 10yrs before the SSD cannot write anymore data. When a flash cell cannot be erased/written to it is simply write protected. No data loss just the data cannot be changed. The data will then be retained for 10yrs before all power in the cell is degraded/lost like a Sanyo Eneloop NiMH battery. You can find proof of this by look at usb flash drives and reading the data retention lifespan for brand new units. My Verbatim Stor 'n' Go Pro says 10yrs on the packaging. In 10yrs it might cost the same price for a 1TB SSD if not cheaper.

I don't know the life expectancies of other brands but reviewers claim other brands to be much less in years and they also claim that at least the number of erase cycles per cell should hold true for all brands.

 

6-7 years? are you kidding me? The near future SSD technology will easily make the current offerings even from Intel obsolete in THIS YEAR...(you will not be keeping the same system(s) for that long because price/performance and some other economic factors will make it worth it to upgrade at least a few times in that time period.

Seriously, I think the Samsung drives will last that long, their wear leveling algorithms are the best in the business -- thats why they are at the top of the list in reliability/

 

Wow , Is the reliability better than the Intel's?

 

Can anyone recommend a ssd for my asus g73jha1? I could spend hours on web finding this out myself but I am exhausted from reading and browsing the web recently to find the perfect notebook to suit me.

What is the fastest ssd in the 200-350$ range. speed is more important that space in my case but 32gb will be on the tight side. It will mainly be used to watching hidef movies, gaming, browsing, downloading and general use.

And please no spesific brand fanboy suggestions. An honest suggestion from someone with good knowledge what they are talking about would bee much apreiciated.

 

No, they cannot.

 

LOL, whoops! 64, of course.

 

A 80GB G2 Intel would be great for your OS and a few choice applications, and then a HDD of your choice for your movies and other games.

No need for an SSD for movies, even 1080p ones.

 

The 100gb Vertex LE is the fastest SSD in that price range @ $339.

If you are downloading those movies you definitely do not want an Intel SSD because the sequential writes are terrible -- often slower than mechanical HDD's. D/L'ing and transferring movies is mostly large sequential writes.

 

OCZ Vertex Limited Edition drives just die when you hibernate.

i.e. they are absolute junk.

And about downloading film - don't tell me 100-110MB/s (MegaBytes, not MegaBits) aren't enough.

 

He doesn't have a Macbook Pro, afaik it's limited to Nvidia chipsets and the manufacturer has been able to flash those drives and return them useable to Mac owners.

Run Iometer 4k aligned 512k sequential write 3 minute test on Intel SSD and you will be lucky to get 70mb/s. sloooow and not worth upgrading to SSD for his purpose. He said no fanboys!

 

As far as I am aware its not limited to s specific laptop.

Anyway - its a sandforce controller that compresses data - brilliant for data security - 100% useless.
(What do you do if the controller dies?)

This also means that it will be dead slow for things it can't compress.

And speaking about "fanboyism" - if you want to buy an aircraft would you take the one that crashed a few days earlier where the manufacturer said they can repair it?
Surely not.

And 70MB/s are still not slow.

 

I want this 100+ MB/s internet you seem to have.

 

I was just about to jump in with a similar response but you have hit the nail right on the head here... What kind of an aircraft was that anyway?

 

Hi it;s me again ...
I have found one site where they saying about Win 7 Ult 64 Software RAID..
But guys in comments they haven't mention third drive to be needed
One guy talking about before installing OS .. by pressing shift + F10 ..

 

Here you go: http://www.alanjlee.com/blog/a-few-notes-on-windows-7-software-raid/

 

eem i know that web

 

So, out of curiosity, what are the top dogs in 250GB+ department?

 

Indilinx and Samsung have been tried and true.

 

Any specific models I should look out for? I'm still getting tempted to use a larger, slightly slower SSD for a game/storage drive

Even though the Hitachi is more than fast enough. Damned epeen.

 

what about intel? i thought they were good in the whole department of SSD's...

 

I dont think that there is any doubt who the top controller has been since its release; no need to mention it really.

 

Only problem with Intel is the 160 GB is still their largest. That's supposed to change soon. For real this time.

 

Which is why I asked for 250+ GB.

But anyway, Samsung and Indilinx, is it? Any particular rebrand or version that should be ignored or looked at more closely?

 

Yeah, Forge asked for 250+GB, where there is no Intel product currently available. They are all pretty much the same drives, though some use cheaper/variable flash memory (such as OCZ Vertex vs. Agility).

 

Here is a little easter benchmark.

My old Intel SSD - 160GB G2


What's the trick - benchmark in Safe Mode for close to maximum performance.
The text file are speed results from AS SSD Benchmark.

 

Those are great scores that I cannot reach with the same drive... Not far off though...

 

Try in Safe Mode - mine are substantially different when used "Normally" - especially the 4K write values.

This makes me thing the OS is using the drive no matter what when benchmarking.

 

Yup...Virtually identical now tx! Learn something new every day....makes so much sense doesn't it.

 

I first noticed that on WPrime - you're welcome

 

Dual booting Windows 7 and Ubuntu 10.04 on an Intel 160GB G2? What problems would I have with trim, alignments, speed, ect? Right now I have 117GB free. The Ubuntu partition would be small, up to 15GB at the most since I want space in Windows for recordings with Media Center.

 

Nice bench numbers guys! Safe Mode rides again! Sure does make sense. Dave

 

Hey guy's whats up, so what's the best 256 ssd to get currently right now?

 

look these ssds are high end mostly on top
if you want 256 its crucial very expensive

 

Wow the intel g2 160 ssd has less compacicty but more write and read speeds.

 

And Intel G1 is the top scorer?

 

WD Rules! http://www.wdc.com/en/products/Products.asp?DriveID=786

 

Any answer for this question?

 

Hooray. Scored two Intel G2 160GB drives for $369.99 each... less 8% Bing and whatever eBay bucks gives me (2%?).

Need to muscle that Babyhemi out of the marketplace, haha.

And, of course, paid on credit card in case there's any funny business.


EDIT: Retail, by the way.

 

I did some read benchmarks on my two OCZ Vertex 30GB drives today while I was troubleshooting my RAID 0 array on the OCZ Forum. I'm quite pleased with the speeds. For some reason, though, my RAID 0 array only reaches an average of 300MB/s. I've still got my fingers crossed that they'll help me find a solution.

Another thing that seems weird to me is that one of the drives fluctuates a lot between the minimum and maximum, while the other remains fairly constant and doesn't deviate much from the average. Any idea why that would be?




Here are the results from my benchmark on the RAID array, which are not quite where I would expect them.



All of these tests were done with a block size of 8MB instead of the default 64kb. Both of the drives also have the latest firmware (1.5) and were wiped with Sanitary Erase.

 

The top Intel G1s are the Server ones at 32 and 64GB - I think the 64 one is around 900-1000$ - not your average SSD.

 

Ah, okay. Was gonna say, there.

What to do with two spare Intel 160GB G2s, though. I'm entertaining the idea of replacing my 500GB Hitachi with the Intel. Gah.

Or I could turn a nice profit on them. Choices, choices.

 

Use one, sell the other

But definitely keep at least one

 

I can't make anything official, since I don't even have the items in my possession, but I'm thinking something along the lines of $400 buy-it-now on eBay, shipped. I will of course cut a break to an NBR member who wants them, maybe along the line of $380+Bing. Stay tuned.

I already have have an Intel G2 sitting as a boot/program drive in my notebook, next to a 500GB 7k500 for media. Still think I should keep it. I'm really more interested in getting a [slighty] slower 250GB+ at least.

But it's so damned tempting.

 

Hey, looking into buying a SSD, Should I really pay 400$ to get a 160gb Intel G2 or the difference between these and the kingston is not that bad for the price ( I could grab a 128gb kingston for 300$)

 

$400 is a nice price. It's how much I got my current drive for.

Budget allowing, try to stick with Intel.

 

Is it really worth it? 400$ is a big investment :S
