Write amplification sand force sf 2281 issues

It is hard to believe that SandForce only opened their doors just over a year ago and their impact has changed the way we are looking at solid state drives today.

Earlier this year, I made a statement that I believed SandForce to be in a position to equal those who have made such great impact on computer technology before them, most noteably Intel and Microsoft. I will stand by that and after reading a bit of what we have to offer, you just may understand why.

Its a great illustration to show, not only how SandForce has progressed since their first release in Q1but also what the SF processor is capable of. SandForce has boosted the 4kb random performance to 60, which is going to be great news for those not quite ready for the jump to SATA 3 yet.

It was only a few months back that we started seeing any SSD come into the point area of PCMark Vantage and those SandForce drives seem to have all done it parallel to a firmware refresh or update to which their 4k IOPs performance was given a higher rating.

Although its hard to differentiate from one drive to another with many roadblocked at the max bandwidth, Vantage has been able to establish a new medium where 8 typical user activities are scored by the transfer speeds of the storage device.

Not Just Another SandForce SSD

The simulated tests are then scored and a suite score provided. An IOPS specification of 60, is double that of the SF and there will definitely be an improvement in performance. Both are capable of a maximum 60, iops at 4k random write access.

For the most part, both processors are very similar and capable of capacities up to GB, both now having bit AES encryption and having 8 flash channels with the only difference being that the SF has 16 byte lanes vice 8.

There are no drives set up with this just yet but eventually SF based drives using these processors will not require any over provisioning whatsoever and the user will benefit from total NAND capacity as they do with most other brands of SSDs.

Simply, typical controllers today write the same amount to the flash as they read so its a given that it is going to take longer to write the data.

SandForce has succeeded in maintaining a write amplification of less than 1 which provides benefit to SSD longevity as much as it does performance.The chip features nearly more than double the ONFI channels as an SF, which reflects on the drive's advertise performance numbers: up to 1, MB/s reads with up to 1, MB/s writes; up to , IOPS 4K random reads.

One major performance advantage in the new processors is the ability to read and write data with the same speeds due to a low write amplification rate, according to Smith. Using DuraWrite, SF controllers can compress the actual, physical data written to the Flash to reduce the write amplification factor (the amount of times the data is .

The SandForce SF series has become the unicorn of the SSD industry. For the past two years there has been a lot of hype about the new controller, but Seagate/SandForce has kept missing. Aug 19,  · Amplified. Due to the way data is stored in blocks, with a normal SSD you'd expect much more than 25GB of data to be written to the flash cells, hence the term 'write amplification'.Author: Jeremy Laird. Jun 04,  · SandForce initially released a family split into enterprise (data center) and client (desktop) computing applications. The SF was the enterprise product and the SF the client product.

What we can say, however, is that the 60 and GB SSD s we tested perform right on par with OCZ's Vertex 3, the first SFbased drive we tested almost a year ago.

At the same time, Intel must now contend against the legion of other vendors peddling drives based on similar technology.

Last week we brought you a preview of the OCZ Vertex 3 Pro SSD whose target demographic is the enterprise sector.

Today, we’re following that.
