hmm most probably payload issue
afaik from looking at the AFudos Bios editor for Asus bios
they are all set at 128
when x58 can do 256's on the IOH PCIE lanes
and for raid cards it will support up to 4096 ( although most of them i see are at 512)

guys is this a good SSD? OCZ VERTEX 2 60GB.

Yup.

Its often the ssd used as comparison for the new sandforce drives and crucial C300's

if you could choose between Intel X-25 40GB SSD or the OCZ, which one would you take?

Viewnet is selling Kingston SSDNow V Series 128GB (SNV425-S2/128GB) for RM 780 if you pay in cash.

definitely the ocz
ure comparing a value series 40gb vs a mainline/performance series of ocz

eh still a lousy value series

a SSD cant effect HDD write speed right? I cant use anything much with 40GB right

I don't know if it is this particular SSD I got, the batch or a quiet subpar release, but it doesn't perform as well as my previous one on random access.

nope. and nope.

80gb perhaps. when gen3 comes out, which hopefully adjusted to the price of current 40gb.

SandForce Unveils SF-2000 Series SSD Processors, Enabling Up to 500 MB/s over SATA 6G

SandForce Inc., the pioneer of SSD (Solid State Drive) Processors that enable standard NAND Flash deployment in enterprise, client, and industrial computing applications, today announced the availability of the SF-2000 Family of SSD Processors optimized for SSDs deployed in mission-critical Enterprise and Industrial computing applications. These chips feature a 6 Gigabit-per-second SATA host interface, industry applauded DuraClass Technology, an unprecedented 60,000 sustained random read/write IOPS (Input-output Operations Per Second) and sustained sequential read/write performance of 500 Megabytes per second. In addition to state-of-the-art performance, reliability, security, and Serial-Attached SCSI (SAS) connectivity enhancements, the SF-2000 family supports single-level, multi-level, and enterprise multi-level cell (SLC, MLC, & eMLC) NAND Flash families from all major suppliers with its high-speed ONFi2 and Toggle Flash interface.

"The market for SSDs is poised to experience rapid growth over the next few years,” said Jeff Janukowicz, research manager for Solid State Drives at IDC. “Solutions, such as the SandForce SF-2000 Family of SSD Processors, that enable increased performance and higher reliability in a flexible design will enable SSD vendors to meet the demands of this fast paced market."

The SF-2000 SSD Processor Family addresses the needs of Enterprise and Industrial storage markets with configurations and firmware optimized for each segment. These devices preserve the advantageous SandForce ”DRAM-less” architecture (no DRAM components required) which is optimal for dense and custom tiny form factor native SATA SSDs, in addition to SAS- and PCI Express-based SSDs when integrated with industry-leading RAID and Host-Bus Adapter chips on one card.



Additionally, SF-2000 SSD Processors feature:

* Support for advanced 30nm- and 20nm-class Flash with Asynch/ONFi2/Toggle interfaces with data rates up to 166 Mega Transfers per second
* Enhanced dual-ported SAS bridge support, including non-512-byte sector sizes, e.g., 520, 524, 528, 4K, etc., with Data Integrity Field (DIF) for true Enterprise-class SAS drive behavior and performance
* TCG Enterprise security with selectable multi-banded 256/128-bit AES encryption with line-rate double encryption for data written to the drive
* Advanced ECC engine correcting up to 55 bits per 512-byte sector to assure high data integrity and support for future generations of Flash memory
* Power and performance throttling options to support green computing initiatives
* Industrial temperature support (-40 to +85 degrees Celsius)

“Eighteen months ago, SandForce transformed the data storage industry by being the first company to demonstrate ground-breaking SSD Processor technology that enables MLC flash to be used reliably in enterprise-class SSD applications with world-class performance,” said Michael Raam, President and CEO for SandForce. “We are building on the success of our first generation product now in production with multiple Enterprise OEMs by introducing the SF-2000 family that offers significant feature and performance enhancements for our rapidly expanding customer base of trusted SandForce Driven Enterprise and Industrial SSD manufacturers.”
Live SF-2000 Product Demonstrations At Storage Networking World!
SandForce will demonstrate SF-2000 products at the Storage Networking World Exhibition, booth #413 (Gaylord Texan Hotel, Dallas, Texas, October 11-14). SandForce 2.5-inch SSD reference designs will be on display operating with 30nm-class Flash memory with both ONFi2 and Toggle interfaces. Other products on display in the SandForce booth include unique form factor products from various SandForce Driven SSD manufacturers with SATA, SAS, and PCI Express host interfaces. All SandForce SSD Processors include award-winning DuraClass Technology with features like RAISE to reduce field failures and returns, DuraWrite to optimize MLC endurance in write intensive applications, and a high sustained and balanced read/write performance.

Is this the cheapest one in MY? For a TRIM support SSD, It's quite worthy.

It is the cheapest on a RM/GB basis. But the one I got from Viewnet doesn't perform fully to my expectations.



Benchmarks from the Kingston SSD I bought in May.


I installed Windows XP (no OS TRIM support) and have been using it very roughly since then.


It sure held up pretty well with it's internal TRIM support.


The new Kingston SSD of the same model bought this week. Installed Windows 7 on it.



A snapshot of the biggest difference between the old and the new:



I think the problem is the firmware. The versions reported are different.

the later results looks like abit slow in transfer rate.

You mean the results for my first SSD after 5 months of wear and tear? That is normal for any SSD after they have been "used". But their performance probably will remain stable after that because of TRIM.

Older SSDs without TRIM support will continue to degrade in performance until they perform worse than HDDs. This is the reason why the older version of the Kingston SSDNow V Series 128GB should be boycotted, as it did not have TRIM support.

Also, OSes without TRIM support (eg: Windows XP) should not be used with SSDs that do not have internal TRIM support, which the newer Kingston has.

wow, never expect that the ssd degrade so fast.
merely a 5 months usage, already drop to near hdd performance.

how about SandForce driven SSD? compared to TRIM?

It didn't. The first two screenshots were from May and the next two screenshots were of the same SSD today. In terms of sequential read, it only dropped 6MB/s. In terms of random access, it did also dropped but they're still far more superior to that of HDDs.

First SSD, fresh (May) and used (October):


I expect that the performance of the SSD will maintain about the same as the second screenshot five more months from now, thanks to TRIM.

Second SSD, fresh (October):


Samsung F3 HD103SJ and Western Digital Caviar Green WD10EADS


As you can see, it will take a far more serious performance loss before modern SSDs will perform worse than HDDs.


SandForce SSDs still uses TRIM. SandForce's primary performance advantage comes from that they compress the data and use data deduplication (removing duplicate data) to reduce the number of read and writes significantly.

oops, sorry. i mean this result:
the transfer rate looks like abit slow.

Intel's 3rd Generation X25-M SSD Specs Revealed



*** i think this is disturbing.... for X25M-G2 the drive lifespan is only 15TB max?? assuming for 80GB SSD at 7.5TB writes, that is only abt 96 whole drive rewrites!, i dunno whether this is something to be concerned of or not..

looks like didn't have much improve on transfer rate.
