  • newegg The high-performance stable upgrade The Plextor M3 Pro is designed to be the ultimate notebook performance upgrade. This 128GB SSD comes with random read and write speeds of 75,000/69,000 IOPS and 535/350 MB/s sequential read and write speeds. The latest 24nm synchronous MLC NAND flash modules with Toggle mode support from Toshiba further enhance product reliability. The DDR3 DRAM cache transfers data faster and helps extend lifetime of the product. The drive’s constantly high performance and True Speed-based stability result in outstanding real-world performance releasing the full potential of your notebook.
  • newegg A Superior PC Experience In addition to enhanced performance, the M3 Pro SSD promotes cooler, quieter, and more energy efficient conditions compared to traditional mechanical hard drives. With no moving parts, SSDs provide peace of mind with their superior durability and reliability.
  • newegg Trim Support The M3 Pro SSD offers TRIM support than can be enabled in Windows 7. Designed to maintain the performance of SSD at an optimal level over the lifetime of the drive, TRIM functions by actively deleting invalid data from the SSD’s memory cells to ensure that write operations perform at full speed. Since a memory block must be erased before it can be re-programmed, TRIM improves performance by pro-actively erasing pages containing invalid data, allowing the SSD to write new data without first having to perform a time-consuming erase command.
  • newegg 2.5" to 3.5" Bracket Included The M3 Pro SSD is specifically designed for notebook computers coming in a 2.5-inch hard drive form factor. In addition, the installation kit includes a 2.5" to 3.5" bracket for matching with 3.5” drive bay to extend the storage of your desktop computer.

5 out of 5 eggsM3P another home-run by Plextor

Pros: Consistent performance, easy firmware updates, elegant case and handy bracket. The M3 Pro is not the fastest thing that has graced creation, nor is it the cheapest, but it is plenty quick and always delivers when called upon which is the true value driver here (sorry for the business jargon). No strange pauses or stutters, no wild fluctuations in throughput, no crashing, no BSOD, no crossing fingers hoping the computer will boot or come out of sleep okay. No need to spend every waking moment in a cloud of paranoia. I'm getting into my 30s, so less worry is a big deal nowdays, esp since this thing is on my work computer. Plus, a 5-year warranty and the Plextor name.

Cons: Price premium may be difficult to justify to first-time buyers who are not familiar with Plextor / have not used or owned other Plextor SSDs.

Other Thoughts: I have not used the bundled software. I have also not had to send anything in for warranty work or otherwise contact Plextor customer service. That being said, I have a M2S and a M2P SSD and never had an issue with either. I'm glad to see Plextor appearing on more comparison charts and showing up in reviews. This is not a "me, too" product, so it deserves the attention. My M3P is currently on a 3ware 9750 in a mirror with a M2P since April 2012 and works great.

5 out of 5 eggsThe wait is over!

Pros: Lightning fast
Firmware is a breeze to flash
Small, light, and cool

Cons: Price I guess but you get what you pay for!
Shipped with very old (v1.0) firmware and the flash tool doesn't let you create a bootable thumb drive, CD only. Not a big deal but you'll want to check the firmware and make sure you're up to date (v1.04)

Other Thoughts: Upgraded my 3x Vertex 30GB RAID 0 to this single drive. Wanted to get TRIM back plus add a bit of space and reduce boot times by dropping the RAID screen. Complete success! AS SSD scores went from 237/67 R/W to 221/218 R/W and that is still on SATA 2. If you've been waiting to get into SSD or you jumped into a first gen. model, it's time to upgrade. Anyone with SATA 3 should have this drive, it's great!

5 out of 5 eggsAmazing SSD

Pros: Marvell controller. Probably the fast marvel-driven SSD on the market. Amazing IOPS and sequential reads/writes. DDR3 Cache, 5 year warranty. Server grade toshiba flash memory. Very, very nice enclosure. I have yet to find a picture that does it justice.

Cons: Pricey, but I was definitely willing to pay for the performance it it is well worth it.

Other Thoughts: I have two of these in RAID 0 and they beat my patriot pyro (new sandforce) in every possible way. Solid as a rock, and blazing fast. WEI score of 7.9 with 238 gb of useable memory. They worked out of the box with my Dell Precision M6600 and boot times run at 4-5 seconds from post to desktop. Haven't run any ATTO benchmarks, but I am completely pleased with these SSD's. I have a decent amount of experience with sandforce SSD's and can see why the Marvell controllers have such a strong following. Crucial SSD's are similar but significantly slower, and intel is switching over to sandforce. Shame on them.
