SSD Terminologies

This post has been edited by jinaun: Aug 4 2010, 07:36 PM

momentus i believe has 4GB SLC for caching reads onli..

so.. for read operations.. it would be theoretically as fast as ssd but writes are still HDD level performance

from what i see, its actually the combination of controller/firmware/flash that determines the performance of the SSD drive

This post has been edited by jinaun: Aug 6 2010, 08:11 AM

use the intel ssd toolbox to check how many GB has already written ..

post ur toolbox smart screen

well.. here is the readout from mine

its a known issue.. you have to completely power down the computer.. cold boot instead of warm reboot

check out corsair forums abt the F series drives randomly disappear upon reboot

are you using the first gen intel ssd?

iirc, 1st gen does not support trim

corsair F series currently may have issues with certain pc conf...

pls check in corsiar forums first prior purchasing..

i think its the same principle is pairing 2 different HDD

the faster drive will have to compensate for the slower drive

i wonder whether trim is supported when using windows buildin raid function...???

i know when using hard/bios initiated raid.. trim will not work

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.

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..

pls check corsair support forums

http://forum.corsair.com/v3/forumdisplay.php?f=188

esp in here http://forum.corsair.com/v3/showthread.php?t=88341

i'm not sure whether its confined to corsair's drives only.. or it effects all sandforce based drives..

This post has been edited by jinaun: Oct 11 2010, 01:31 PM

the manufacturer gives 3 years warranty.. so you should expect at least 3 years lifespan.. but

and iirc patriot gives 10 years on its drives... so typical life should be somewhere between there 10 and 3 years... (just speculation)

but since ssd is quite young in the market... its still hard to say

pls note that the *VTXE* model numbers is not vertex 2 EX series

*VTXEX* is the model numbers for Vertex 2 EX series

and your prices for the Vertex 2 is abit higher than the retail

it will come down

but difficult to predict exactly.. but according to moore's law... semicon prices should be 50% cheaper every 18 months

corsair force series may have some random problems/complains from what i can see from corsair's forums and also computer shops

i'm using intel x25m and so far no problems for me yet.. and its almost a year liao IIRC

bought a Vertex2 for my MBP

noticed that the firmware upgrade size is abt 90MB...

i was beginning to wonder the SSD processor itself is a computer which handles flash management and RW requests from the host OS via some linux/vxworks/uOS

eg.. something like dd-wrt on artheros 9k series NPU

thats y its called ssd processor not ssd controller
