The Plextor M3 (256GB) Review
by Kristian Vättö on April 5, 2012 3:05 AM ESTFinal Words
Let's be frank: I'm surprised. When I first got the Plextor M3, I wasn't expecting much from it. A Marvell based SSD from a smaller, somewhat unknown SSD brand is not too promising. If this had been a SandForce based SSD, then we all know what the performance would be like since all OEMs except Intel use the stock firmware. However, Marvell's controllers require a lot more work as the stock firmware that Marvell provides is in need of work. Having your own firmware team is a must if you plan on competing anywhere other than the low-end market. That requires capital, which can be an obstacle for a small firm. With Plextor being a subsidiary of a massive company, they should have the capital they need, and judging by the peformance results, they do.
The Plextor M3 isn't the fastest drive we have tested, but it comes in very close in many tests. It's clearly the fastest Marvell based SSD and it beats its Marvell siblings quite handily in most metrics. SandForce has been and still is extremely fast, but what Plextor has shown is that Marvell's controllers can keep up with SandForce when equipped with great firmware.
I've only really got two complaints. The first one is Plextor's pricing. I think Plextor may be pricing themselves out of competition in the smaller capacities. While the price difference with other brands in 64GB and 128GB capacities is only about $15 on average, that's quite a lot when put into perspective. In percentages, the 64GB M3 is 16% and the 128GB M3 is 9% more expensive than the other drives on average. If you could save 10% on each component in a new system, most people will opt for pricing over brand name.
| NewEgg Price Comparison (4/2/2012) | ||||
| 64GB | 128GB | 256GB | 512GB | |
| Plextor M3 | $110 | $180 | $340 | $660 |
| Crucial m4 | $88 | $155 | $315 | $630 |
| Intel 520 Series | $110 | $180 | $345 | $800 |
| Samsung 830 Series | $105 | $185 | $300 | $780 |
| OCZ Vertex 3 | $90 | $178 | $340 | $770 |
In my opinion, the M3 would be a lot more attractive if Plextor lowered the prices of 64GB and 128GB models by even $10. 64GB and 128GB capacities are often the most popular capacities right now (as spending $300+ on a single SSD is quite rare), so if you want to be competitive, that's the niche you should focus in. Plextor could even increase the pricing on their higher capacity drives while still remaining competitive. Then again, perhaps Plextor is hoping to skip directly to the more lucrative 256GB and 512GB market, as the lower capacity market is already quite cutthroat.
My second complaint is that reviewing the M3 made me lust for something better, and it's called the M3 Pro. The controller is the same Marvell 88SS9174-BLD2 but Plextor has taken the firmware one step further and this has resulted in better performance. I'm not going to go into detail about the M3 Pro here, but it reportedly provides up to 540MB/s read and 450MB/s write speeds along with random read of 75K IOPS and 69K IOPS random write. Hopefully we will be able to get our hands on a review sample soon.
Overall, Plextor M3 is a good performer - and we didn't notice any issues during our testing. It's fast in every aspect, has good gargabe collection, and isn't too power hungry. There is one big unknown though: Reliability. Current generation Marvell based SSDs in general have been fairly reliable, especially when put against SandForce, but firmware plays such a big role with the Marvell controller that you can't really know for sure.
Compatibility and reliability can take months to months to truly understand, so as always proceed with caution. There are great, known good solutions on the market at competitive prices already so there's no need to take a risk on an SSD before its reliability has been proven.
In any case, it's good to see that Marvell's controller still has legs.

He he, I read the article before the update and it sounded to me like it was written by a 15 year old! Little known Plextor... lolGood thing you updated, but in general when commenting on a company for an article do a little google search in case you are missing something ;)

Just because you can google a company to read about them (Kristian had already done that -- note the paragraph about them being a subsidiary of Shinano Kenshi Corporation), it doesn't mean everyone out there is familiar with the company. I sort of laughed when Kristian said he hadn't head their name until a few months back, but then, there were plenty of companies I wouldn't have known a thing about when I was 17.Kristian Vättö - Thursday, April 5, 2012 - link
My point is that Plextor has not been in the spotlight for years. I was just surprised when the name came up because I seriously had not heard much about them. I consider myself to be pretty updated when it comes to the SSD front but I still had not heard the name Plextor until a few months back. That's why I wrote what I wrote. In SSD context, Plextor can be a new name for many, or at least it was for me :-)I admit that I did not know about their success in the ODD market in the 90s but then again, I was still spoon-fed at that time :-P

On the second page, on the test setup it says "Intel Core i7-2500K." I assume it's an i5 from the 3.3ghz clock?Kristian Vättö - Thursday, April 5, 2012 - link
Yeah, it's an i5. Thanks for the heads up, fixed it :-)BolleY2K - Thursday, April 5, 2012 - link
...are the 5 year warranty and the included version of Acronis True Image, which allows the user to easily clone his existing OS drive to the SSD.These two things are not included in the packages of most other SSDs on the market and in my opinion add to the value of the M3 package, so should be mentioned in the review.
Btw. I own the 128GB and am very pleased with it - easy installation (also due to the included software), good performance and entirely issue free so far. :-)

At least my version did not come with Acronis True Image. The included clone utility is called Echo and is made by NTI. Not that it matters as the tool worked flawlessly when I copied my boot drive to the M3 :-)BolleY2K - Thursday, April 5, 2012 - link
Ah ok - I live in germany and over here you get Acronis. Well, as long as it works, it doesn´t matter how it is called I guess. ;-)I still think these 2 goodies should be mentioned and also kept in mind while discussing the price of the M3. Also the QA of these drives is very good - plextor states 20 hours of testing for every single SSD they ship and a RMA rate of 0,5%.

I picked up a Plextor M3P, and here you get NTI.I went to try it out, and it did not play nice with Acronis which was on my system. After settting it up, the system reboots and loads a linux partition to do the copy operation... well, it didn't work, and then I couldn't get past the linux boot on subsequent restarts.
I could just revert to a clone from a week prior on another SSD, but not everybody has it like that.
The NTI Echo probably works quite well if you don't already have another clone suite installed like acronis.
The M3P is totally bitchin' though.

I got my 256GB M3 for $290 in February and the 128GB often hits $150-$160. Anyway, Thanks for finally doing a review on the M3 and I <3 Toshiba Toggle Nand!!
