The Test
| CPU | Intel Core i7 965 running at 3.2GHz (Turbo & EIST Disabled) |
| Motherboard: | Intel DX58SO (Intel X58) |
| Chipset: | Intel X58 |
| Chipset Drivers: | Intel 9.1.1.1015 + Intel IMSM 8.9 |
| Memory: | Qimonda DDR3-1066 4 x 1GB (7-7-7-20) |
| Video Card: | eVGA GeForce GTX 285 |
| Video Drivers: | NVIDIA ForceWare 190.38 64-bit |
| Desktop Resolution: | 1920 x 1200 |
| OS: | Windows 7 x64 |
Sequential Read/Write Speed
Using the latest build of Iometer I ran a 3 minute long 2MB sequential write test over the entire span of the drive. The results reported are in average MB/s over the entire test length:
I ruined the surprise earlier, but the X25-M G2 160GB can now write at speeds of up to 100MB/s. The 80GB version doesn't get the benefit. The rest of the SSDs are approaching 2x that performance however. The poor Kingston drive is limited by its 5-channel implementation and barely manages more than 40MB/s. This will keep the Kingston SSDNow V series from cannibalizing X25-M sales, while at the same time offering a taste of what good SSDs have to offer at lower price points.
We're nearly tapped out on sequential read speed. The new TRIM firmware appears to drop performance a bit but not much. SATA 6Gbps will be necessary before we can see higher sequential read speeds from a single SSD.
True to Kingston's claims, the SSDNow V 40GB pulls around 170MB/s thanks to its narrower configuration. Not within arm's reach of the more expensive SSDs but still much faster than a mechanical drive.

Ya they had them for about 4 hours in an AM Shell Shocker for $240, which is their MSRP. They also had them for that price for about 8 hours at launch and since then its been gouged as high as $400 for a G2. All the other retailers that are selling for around the $240 MSRP are drop-shipping directly from Intel so they typically don't have stock in-hand and are estimating anywhere from 2-8 weeks for delivery....crimson117 - Monday, October 26, 2009 - link
Amazon has decent prices on these, but shipping time ranges from 2 weeks to 8 weeks.80GB G2 for $244: http://www.amazon.com/Intel-Mainstream-Solid-Retai...">http://www.amazon.com/Intel-Mainstream-...-Retail-...

5 days later now, and Amazon's up to $599 for the 160GB, though they are in stock instead of shipping in several weeks.Exar3342 - Tuesday, October 27, 2009 - link
I bought a G2 80GB yesturday via Amazon from a 3rd party company; was $244.00 (OEM) version. Good times.strikeback03 - Monday, October 26, 2009 - link
With your recommendation to keep at least 20% of a drive as free space, should it be within a partition, or just leave some unpartitioned space on the drive?Anand Lal Shimpi - Monday, October 26, 2009 - link
Either way works, just don't put data on it :)Take care,

Anand: great review.The 40GB 5-channel version has read speeds of 170MB/s. Does this mean that if the 10-channel G2 weren't inhibited by SATA 3Gb/s, it would probably get 340MB/s? Or is there diminishing returns on adding more channels.
Also, any price cuts on the horizon or just stagnating until drives start shipping with SATA 6Gb/s support.

It's possible. All of the high end SSDs are bound by the interface for sequential read speed. I'm not sure how fast the controller could go if it weren't bound by the interface, but over 300MB/s sounds quite likely.Flash prices haven't really gone down lately from what I'm hearing. I don't know of any price cuts on the horizon unfortunately. Next year.
Take care,
Anand

i don't think you will see any price cuts since intel can't make enough G2s.I tend to agree with others regarding SATA 3. If intel is not rushing to enable SATA 3 on their ICH anytime soon, why would they be coming out with SATA 3 devices?

Anand,it's strange to see your
"Is Intel still my overall recommendation? Of course. The random write performance is simply too good to give up and it's only in very specific cases that the 80MB/s sequential write speed hurts you."
of the last review, is now a
"The write speed improvement that the Intel firmware brings to 160GB drives is nice but ultimately highlights a bigger issue: Intel's write speed is unacceptable in today's market."
