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.

In europe plextor is one of the pioneers in the IT industry. They where one of the first to enter the cd-burner market way back in the days. They are generally known in europe to produce some of the finest quality products when in comes to cd-burners and back in the days it was the only burner to own ;)Tor-ErikL - Thursday, April 5, 2012 - link
I'm not surprised that they come up with another good quality product here, they have always been more expensive than others but you always get a good quality product from them.Fujikoma - Thursday, April 5, 2012 - link
The last Plextor optical drive I had broke within months. It was very flimsy and the shipping to have it fixed was more than buying a replacment from another vendor that had the same build quality. Plextor's quality isn't any different than other cheap drive manufacturers even though their price is.Maiyr - Thursday, April 5, 2012 - link
I am still using a PleXCombo 20/10/40-12A. My experience in no way mirrors yours. I got this thing and another drive in 2002/2003 and both are still going strong. No problems.Maiyr

Those were different times.I have two plextor drives:
SCSI UltraPlex 40MAX, the best CD reader ever built.
ATAPI 8/4/32 CD burner. Also a really excellent drive.
Those were "expensive" back then. The ultraplex was $140, the 8/4/32 was ~$90.
After those, drive prices tumbled and Plextor used cheapo OEM drives like everyone else and rebadged them.
Both you and Fukikoma are correct.

Was going to say something similar.It's like how Seagate has had good drives, but they do have bad batches, especially as they're refining their process.
Quality should not be solely determined on the product. How a company responds to a defective, or poorly made product should extend into the definition of quality. It might not be product quality, but quality of the experience is more important.
Like, I might get a bad part off Newegg, but they have great customer service that make it easy to ship it back and receive a replacement or a refund. I know they're only a middle man in the process, but the tradeoff is having a good product with good customer service, that reduces customer hassle.

The thing that makes me wonder what's going on with your post is the way you describe Plextor's quality as not being better than "any other cheap drive". The fact is, there are near a dozen DVD burner brands that cost less than $25 that are reliable pieces of hardware. They are inexpensive, but they aren't cheap.I'm another person with a Plextor drive that's been around for a couple of builds, and will soon go in a third. Do I think it will outlast my LG drive I bought a couple of years later? No, but Plextor help set reliability and top-notch performance standards that are the reasons we have inexpensive and reliable burners now.

ditto: Plextor made one of the best CD-Burner back then (talking only about, just late 1990).note to Mr. Vatto: you could have skipped that the line, we wouldn't know. ;p

Note to our readers: Kristian is 17. When optical drives mattered (in terms of benchmarks), he would have been about 10.Kristian Vättö - Thursday, April 5, 2012 - link
