The Competitors

For the most part, Intel doesn't let anyone else manufacture drives using its controller (the lone exception being Kingston). Indilinx and Samsung however both sell their controllers and designs to many other vendors, who then repackage them and sell them as their own SSDs. The table below is a decoder ring of the drives I tested and their equivalents in the marketplace:

Drive Controller The Same As
Patriot Torqx Indilinx Barefoot (MLC)

Corsair Extreme Series X128
G.Skill Falcon
OCZ Vertex
SuperTalent UltraDrive ME

OCZ Agility Indilinx Barefoot (non Samsung MLC) N/A
OCZ Vertex EX Indilinx Barefoot (SLC) SuperTalent UltraDrive LE
OCZ Summit Samsung RBB (MLC) Corsair Performance Series P256

 

While I used the Torqx from Patriot as my Indilinx MLC drive, it's the same drive and uses the same firmware as OCZ's famed Vertex drive or the new Cosair Extreme Series SSD. The only exception on this list is the OCZ Agility. The Agility uses the same Barefoot controller as the Torqx, Vertex, UltraDrive ME and Corsair X series, but it uses non-Samsung flash memory to lower cost. The Agility currently ships with either Toshiba or Intel flash, but should be roughly the same performance as the other Indilinx MLC drives.

I included the SLC drives as a reference point, but for desktop use they are overkill. Not only is their firmware not optimized for desktop usage patterns, but they are far more expensive on a cost-per-GB basis.

All of the drives used the latest firmwares at the time of publication.

The Pricing

The table below is the pricing comparison I went through yesterday:

Drive NAND Capacity Cost per GB Price
Intel X25-M (34nm) 80GB $2.81 $225
Intel X25-M (34nm) 160GB $2.75 $440
OCZ Vertex (Indilinx) 64GB $3.41 $218
OCZ Vertex (Indilinx) 128GB $3.00 $385
Patriot Torqx (Indilinx) 64GB $3.48 $223
Patriot Torqx (Indilinx) 128GB $2.85 $365
OCZ Agility (Indilinx, non-Samsung Flash) 64GB $2.77 $177
OCZ Agility (Indilinx, non-Samsung Flash) 128GB $2.57 $329
OCZ Summit (Samsung) 128GB $3.04 $389

 

The new 34nm drives were supposed to start shipping yesterday, but I've yet to see them available online. It's also worth mentioning that Intel doesn't give out street pricing, only 1,000 unit pricing. The street price of the X25-M G2 drives could be higher at first, similar to what we saw with the 1st gen drives, eventually leveling off below the 1Ku pricing.

    Hi, thanks for the great article, although would love to see reviews on the smaller capacity drives (e.g. the 80GB Intel) that most people buy, instead of the expensive ones.

    Also I read terrible reports of unreliability on Intel SSDs (blue screens, incompatibilities). It seems way too risky to me to put any SSD in RAID-0

    Would love a review on the new Crucial SSDs, they just came out this week, have very good read/write rates, they are available NOW on the Crucial website, are quite CHEAP, but there are no reviews yet, not even what controller they use.

    No technology is 100% reliable. Even enterprise hard disks fail quite a lot. Intel's SSD is as reliable any other SSD. I dont think you have to worry on that count.

    I wish intel had bumped up the warranty to 3 years. That would speed up the adoption of ssd.

    I too am disappointed that Intel have failed to improve their sequential write figures when everything else seems to have been.

    What I would like to know is if Intel can do anything with the G2 firmware that will improve sequential write performance without effecting the other numbers? or is this a hardware limitation and as such we will need to wait for the G3 or 34nm SLC drives?

    Also in the real world, where will this sequential write performance bottleneck really affect or be noticable for laptop users? Copying large files to the drive? Unzipping files? or some other task?

    This sort of information would really be useful in deciding whether to go for the new Intel drive or the Vertex in time for Windows 7.

    Out of interest, is there any news on when the OCZ Vertex Turbo drives will be included with these tests?

    Honestly I doubt we'll see significant gains in sequential write performance with this generation. Intel could improve sequential write performance but I believe it would be at the expense of random performance, which for desktop users is a bit more important.

    Copying large files to the drive will be the biggest indication of the limited write speeds compared to the Samsung/Indilinx offerings. Even at 70MB/s the X25-M is faster than any hard drive you'd stick in your notebook, but it's definitely slower than the Vertex/Samsung SSDs.

    In my opinion it's random read/write performance that ultimately matters, as you tend to not copy huge files to such a small drive on a regular basis once you have everything setup.

    I should have the first Vertex Turbo drive by the end of next week.

    Take care,
    Anand

    Personally my feelings on this is that I believe that [medium to large] Sequential Writes are equally as important as [small] Random Writes.
    I have noticed that especially on SSD reviews, the common random write tests are 4kb sized and deemed most important by many.
    I honestly have not seen any one validated bit of information anywhere showing that [small] Random Writes are the highest percentage file IO that desktop PCs write out, in fact it is just the opposite

    Most data files written by common productivity software are almost always larger than 4kb, and most software either performs a backup-rename or write-then-delete so partial file small block update/overwrite is not an issue; with growing web content the browser cache files are getting larger, as is most temp files; and one of the most heavy users of the hard drive is the Windows page file and they are optimized to perform large sequential file writes. See this page: http://blogs.msdn.com/e7/archive/2009/05/05/suppor...">http://blogs.msdn.com/e7/archive/2009/0...nd-q-a-f...

    "Should the Page File be placed on SSDs? Yes."
    "Pagefile.sys reads outnumber pagefile.sys writes by about 40 to 1."
    "Pagefile.sys writes are relatively large, with 62% greater than or equal to 128 KB and 45% being exactly 1 MB in size."

    Personally I am looking for SSDs with higher Sequential Write performance and would welcome some "real world" tests in the many reviews on the Internet since I don't believe that what we are getting is valid information in this regard. For example, 128kb through 1MB writes would give a more valid idea of page file performance on a drive.
    Reviewers need to educate themselves on how the OS works.

    The poor random write performance is likely due to the controller lacking hardware (or having slow hardware) for the MLC ECC calculations. SLC flash doesn't require such heavy ECC, and so the X25-E's don't hit this bottleneck. It's unlikely to be fixed via firmware, though I was personally hoping that they would include it in this new revision of the controller. Reply

    Arrgh, just noticed I put random instead of sequential. Replace "poor random write performance" with "poor sequential write performance". Reply

    Don't know about you, but 70 MB/s is more than enough for me. I'll happily trade sequential write for random write. Especially since the alternatives are so much slower in random write. You'll notice random write performance much more than you will sequential write performance. How many times per day do you copy/move multi-GB files, especially since you're probably only going to use it as a system drive? Maybe a couple times per day? Compare that to the fact that random writes keep happening in the background for as long as you use your computer. Reply

    I've read AnandTech's SSD Anthology and decided to go with the Intel X25-M G1 80GB MLC SSD drive on 2009-06-10 for $314 USD at Newegg. Due to a incompatibility with the nVidia nForce4 chipset I couldn't use the drive and I had to upgrade my entire system early to an Intel Core i7 with Asus P6T Motherboard with X58 and ICH10R. I only got to use the SSD starting in July, 2009 and I've been using it for a month with Windows 7 RC.

    The performance is absolutely fantastic and I think that this upgrade and the troubles were worth it. However now I hear that Intel might not release a firmware upgrade for the Generation 1 drives to enable TRIM support and this seriously pisses me off. On top of this the new G2 drives seems to perform faster for Random Writes. I am contemplating on putting up my G1 drive for sale on eBay now to recoup almost all of the money that I spent on it so I can purchase a G2 drive with TRIM support upgrade potential.

    If Intel would have come out and promissed support for TRIM for the Generation 1 drives I would most likely keep it but unless that happens in the next week or two I'm going to dump this G1 like a hot potato.

    One thing that I would love to know is what is the actual sale date of the G2 drives and what will the street price be for the 80GB model.
