Show us your SSD performance 2

[JerometheGiraff]

What do you mean revisited the Vector later, buy a faster Vector layer and buy a slower SSD for the laptop, today ?

It will depend on the timeframe. If you want to use the Vector in a 6GB system one or two years from now, then I would not buy it today because by that time it will be cheaper and there will be other options. The laptop with a 3GB bus could very well live with a cheaper SSD. This is a good option. I own a Mushkin SSD and it works great.

Any other suggestion, I'd prefer 256GB over 240GB.

So what can I make of this the two readings are from my Ivy Bridge with the Samsung 830 and the laptop with the SanDisk Extreme the Ivy is running an i5K @ 3.4 and the laptop an i5 430M @ 2.27 both with 8GB RAM .

Now I timed them this morning and the laptop booted to start in 16 seconds (using an 8 upgrade) and the Ivy Bridge with 7 booted in 29 seconds so does that mean either the OS is faster or the drive is better?

The 840 is cheaper to buy than the SanDisk and I really wanted to get a 256 for the Ivy Bridge so the SanDisk or the 840?

The fastest boot times I have seen have all been laptops I believe. So, apples and oranges maybe? A Guy

The reboot time is more dependent on motherboard/BIOS features than differing SSD's. Plus, Win 8 boots up faster and the laptop probably has features built in to boot/reboot faster. I would go with the Samsung simply because it doesn't use a Sandforce controller like the SanDisk.....but it is also a faster drive. Look at your 4K and Acc. time numbers on those two drives.....those numbers are the ones that really make a difference in real-world use.

What is the problem or drawback with a "Sandforce controller" ?
Tried looking into this, but can't find any explanations.

Yep that was the only thing that was bothering me a bit was the Sandforce issue anyway the Samsung is cheaper than the SanDisk by about $32 and the one I have hasn't had any problems at all. I get the idea with the rates too they are really significantly faster eh?

Problem at the moment is the dollar and my usual supplier is not selling OCZ or Crucial at the moment so I have no idea on the pricing there. The only other brands are Intel, Fujitsu, and Corsair - which I do like for RAM use (Corsair).

There was a problem with them back around 1st/2nd generation SSD's and it left a bad taste in people's mouths. I originally went with an Intel 520 series SSD(which uses a Sandforce controller tweaked by Intel) for this build, and not 1, but 2 went tits up within the day. I figure if Intel had put 18 months of work into something, and still couldn't make it work, it's just not worth messing with. Also, people were having a fit over Sandforce drives because they put up "crazy" numbers........well, the "crazy" numbers they got in benchmarks were Sequential Read/Writes and they don't mean anything for 99.9% of us. They didn't produce any better Random 4K and Access time numbers than any other decent SSD. There are better controllers that don't have a history of just going bad and bricking the drive for no reason.

Sandforce controllers used a compression algorithm in their process. This allowed a more efficient and faster overall process resulting in excellent bench performance as long as they were working with compressible data. This is why most sandforce based SSDs published ATTO benches as part of their marketing process. However, when faced with incompressible data (example video) the sandforce algorithm lost a considerable amount of its efficiency as evidenced by poor performance in tests such as AS SSD. For most average users the sandforce based SSDs tended to maintain their performance since typical use did not work with large amounts of compressible data. That's one reason amongst many others that companies such as OCZ have developed their own customized SSDs that no longer have this compressed data limitation.

John, I'd go with the Samsung 840 it uses the same DDR2 nand 400Mbs and 3-Core Samsung MDX Controller as the 840 Pro. I have some SanDisk USB stick and they are the slowest ones of the lot. Still ANY SSD would be an improvement over ANY HDD.

 

[A Guy]

I think the real feel speed of any SSD will be relatively the same. A reliable brand would be most important unless you want the best and can afford it. A Guy

So you think the 840 is just as good as the 840 Pro ?

I put an 250GB Regular 840 in a build I did for my Dad, the PC runs awesome. If you are not into numbers then it performs just great.

Thank's for the link, it was an excellent read.

Thinking ahead for future M$ updates and when Win7 expires going to Win8 would it make more sense to get a 256GB over a 128GB ?

I would always say get as big as you can afford Bob, the 240/250/256GB ones seem to be reasonably priced now, in fact around the same price as my first 60GB one a few years back.

It also depends how you are going to use it. 128GB is plenty if you are gonna have a regular HDD for storage and for games if you have loads.

The Samsung Pro 256GB is $215. at NCIX. The OCZ I have now, was $79. when new a year ago, now on newegg it is $190. this I do not understand !

My thought is to buy this one time and not be sorry in a couple of years, thinking back, why did I not get a bigger one. This is one reason why I did not buy the 128GB last week.

Too many SSD beginners get impressed by the big numbers. But what you usually see are sequential transfer times of large blocks. However, for the OS those are completely irrelevant. The numbers to focus on are access time and 4K random R/W speeds because that's what the OS uses most of the time.

A good SSD that is suitable for the OS should have an access time around 0.1ms (as measured with AS SSD) and a 4K transfer time around 100MB/sec (as measured with Atto).

Thanks Gary the 840 it is then when the cash flow is sorted.

You mentioned DDR2 NAND gate chips so does the Pro have a higher DDR NAND gate set in it say DDR3 or simply a faster DDR2?

Quoted for truth. Cannot stress this enough, for an OS drive, the advertised speeds are worthless. Number one factor before buying would be reliability, then performance. Any of the top drives should perform within a few percent of each other so you basically find a brand with a good reputation of being reliable and look to catch one on sale.

While browsing I found this site - probably known about already but if not id quite good .

The SSD Review « The Worlds Dedicated SSD Education and Review Resource | The SSD Review some really good reading for no brainers like me

PS the Guides tab then the SSD database gives al the brands and what controllers they have.
