What is the point when drives aren't even hitting 1.5Gb/s, and they definitely aren't even coming close to 3.0Gb/s?

RAID performance with multiple drives?

newtekie1What is the point when drives aren't even hitting 1.5Gb/s, and they definitely aren't even coming close to 3.0Gb/s?

The newer intel SSDs hit way over 1.5Gbps (about 250MB/s read speed) and a faster SATA standard would allow them and others to design an even faster drives, I dread to think how much they would cost though. Hopefully by the time motherboards with SATA 6Gbps are released, SSDs will have come down in price.

1.5 Gbps is equal to 187.5 MB/s

3.0 Gbps is equal to 375 MB/s

SSDs have reached these speeds. BTW there may be improvements with the response time too.

SSDs are coming extremely close close to the limit of 3.0Gb/s. It's not there yet, but it could be. It's more of a preemptive strike. When PATA was the standard, it was getting beat before the newer revisions were out.

HDDs, however, are barely struggling on the 1.5Gb/s SATA. Next gen HDDs will be within the current SSD read/write levels. I actually prefer a HDD to a SDD.

oh joy..my 2x 1TB HDDs just became obselete in theory /cry

I seriously doubt their will ever be a next generation HDD. Due to the fact their is really nothing else they can do to make an individual drive any faster than it already is. Density is being pushed to the max as it is, we already have perpendicular magnetic recording. Really what else can they do? SSD's the sky is the limit, newer faster memory is always right around the corner.

6GPBS = 750MBps. That's fast!!! But I doubt the drives will really do 750MBps.

agree, i give SSD's ~5-10years before they're standard and HDD are to SSD's like CD drives are to DVD drives

Intel's high end SSD drives have not even come close to reaching these speeds. Burst speeds are only hitting 250MB/s, and sustained read speeds are only 230MB/s. No where near the 375MB/s given by SATA 3.0Gb/s. And it is unlikely we will see SSD drives breaking the 375MB/s mark.

I doubt it, SSD drives still have horribly short life spans and that won't change any time soon. I'm not going to pay $500+ for a 32GB drive only to have it fail after a year of use.

hey the best ones are only $300 :p but i hear you i won't buy an SSD until they're prices around 250gb fro 100-120. True SSD's won't change anytime soon, but 5-10years is a good amount of time especially in the computing world.

OMG does this mean I have to upgrade to another motherboard once it arrives? If upgrading is not as easy as BIOS updates I'm going to go nuts!

Depends on price alot too to be fair if there talking stupid money then it wont catch on as much till prices fall

I wish they would come close to the limit of my wallet :cry:

newtekie1What is the point when drives aren't even hitting 1.5Gb/s, and they definitely aren't even coming close to 3.0Gb/s?

the Gb speeds are misleading. they include signaling data. The real speed of SATA-II is 300MB/s, and there most definately are SSD drives out there doing 250MB/s+

Within 2 years, its very obvious that SSD's will be outperforming SATA-II's 300MB/s limit, so if they release SATA-III this year it gives time for PC's to upgrade at the same rate as SSD's.

a lot of people here seem to be focussing too much on the synching of the timing of the current SSD speeds and the interface.
worry less about TODAYS SSD speeds and the interface they use, and instead realise that SSD speeds are increasing incredible fast compared to the interface they use.

SATA 1.5gb/s=2001
SATA 3.0gb/s=2005
SATA 6.0gb/s=2008

as you can see it takes a while for the transmission standard to evolve (although looks to be evolving faster).
SSD's have been around in various forms since the 1990's, with the military and specialist companies enjoying the cutting edge technology of the time compared to disk platter based drives.

compare the SATA spec evolution with the evolution of the SSD speeds. where in just the 1st two years (of "consumer" SSD's), where DELL, Apple and Asus were using them.

the 1st SSD's 2 years ago barely managed 50/25 (read/write).
today, regardless of price, we already have SINGLE (not raid) SSD's that can handle nearly 300Mb/s transfers!

the evolution of the drives is outpacing transfer mechanisms. it seems the tables have turned as for many years single hard drives never approached their interface limits.
this is why the SATA spec can't evolve fast enough for us.

it matters less that it seems to be overkill for TODAY's SSD's and is more about future proofing us. it will be another few years before the storage device interface spec evolves to accommodate us, and by then we can only imagine what speeds we'll be transferring.

insiderRAID performance with multiple drives?

Every SATA drive has the full bandwidth anyway, so it won't matter. Unless you're using multiplexers, which few people actually do. It's only interesting for RAMdrives and future SSD's. Normal harddrives won't get that fast in the coming years.

DanTheBanjomanUnless you're using multiplexers, which few people actually do.

I do! i has a port multiplier.

Anywho, dan is definately right on single drives, except for SSD's. SSD's are definately already 250MB+, and reaching the limits of SATA-II

6GB Burst / peak? So not 100% of the time like most would like to believe haha.

loool
SSDs have already successfully gone past the 375MB/s barrier...
SATA is so slow right now compared to current generation SSDs (only 1 company currently has current gen SSDs, and thats Micron Technology, Intel is still last gen)
They have a current sustained write speed of over 600MB/s. Add another SSD (they are expandable) and get 1100-1200MB/s sustained Writes...
So, its coming in line with Micron's release date for their SSDs (1Q-2Q 09).
Hope ya'll enjoy your el-cheapo Intel SSDs. ;-) Slow pokes.

cough. seen your system specs lately? :nutkick:

Musselscough. seen your system specs lately? :nutkick:

:roll: That shit's funny

Lol, I've been reading this argument since ATA33 vs ATA66 ;)

i think maybe new technology release for ssd maybe like raid give us high bandwidth

This is terrible information. Do not trust.
