This is a good mSATA SSD for those of you with the proper port. I have the Lenovo y500 and put this into the mSATA port to install the OS on. (I had to get win8 iso and do a clean install). Speeds are great, boot time is in the 10 second range. I'm not sure why this has so little attention on Amazon. This and the Mushkin Atlas are both great choices, but either are way better than the much more popular and outdated Crucial M4.
Benchmarks on TheSSDReview give some good information on these choices.

I had 119/128 gb available after formatting, which is expected.

Worth noting is that the 128 gb model has different speeds than the 256 gb model. The benchmarks display that speeds should be 540/320 read/write for this model. Amazon has the maximum speeds listed probably from Plextor's site(they don't specify model difference), but those only apply to the 256gb model. You can confirm these speeds at any other retailer site NE, TD, or review sites.

I installed this msata SSD in the WWAN slot in a thinkpad x131e. Boot time was improved. The windows experience for disk went to 7.9 on win7. The install was easy. Net: works well.

Details on the Thinkpad x131e install:

Remove the battery. There is a big panel on the bottom of the x131e that covers all common user replaceable parts (memory,network, wwan, msata ssd, hard drive). Loosen three screws on the panel on the bottom of the x131e but leave them in the panel itsself. Then pivot the panel up from the screw end and remove it. Download the thinkpad service manual from lenovo to see a step by step on how to open the bottom. Very simple.

With the bottom open the WWAN slot is directly accessible. The x131e I was modifying had a 4G modem installed in the WWAN slot. That gets removed by lifting straight up on the antenna wires where they attach to the 4G modem. The wires stay in the thinkpad. The WWAN card gets removed by removing one screw and then lifting the 4G modem up at the screw location pivoting at an angle around the slot.

Once the WWAN slot is free insert the Plextor M5M mSATA drive into the WWAN slot at an angle with the contact edge of the card in teh slot and the opposite end higher. Once the card is sliding into the slot lower the other end of the card. When the card is flush to the motherboard screw one screw in the upper right corner (where slot is on the bottom). I used the screw that was holding down the 4G modem I removed, however the Plextor drive comes with two screws in the package. The Lenovo manual says to only use one screw, so that's what I did.

I installed this into a laptop to serve as the OS/app drive while making the included HDD the media/game/backup drive. When I initially installed it, I couldn't install windows to it since the installer didn't even detect the drive. I had to boot into windows (from the HDD) and format the SSD before it was detected by windows.

After getting everything sorted, the SSD has worked beautifully. Windows 8 loads super fast and opening firefox doesn't take painfully long (compared to my old laptop with a 5400rpm hdd)

I bought this as an aftrermarket upgrade for my new Lenovo X230 computer. After installing this and the 8 extra gigs of ram (12 total) my computer is one of the fastest machines I ever seen! It boots from cold to ready-to-go (windows 8) in under 4 seconds! Before I installed this drive and moved the data over to it, (after the memory) it was like 12-15 seconds which is still very good but the machine runs great now, no lagging or waiting for anything (except internet if Im not on a good connection).

Back in the day, Plextor made some amazing optical drives -- the best. And while that may not have at all reflected on the quality of what this product would be, I did like the idea of it.
I purchased this to put in a Drobo 5N in order to speed up transfers of "Hot Cached" files. I believe it does fill that role, but without with / without testing, I can't confirm for sure if it is giving me the huge increase that I would most certainly love to have.
That being said, it is working fine, and if there is any problem -- it is not with this mSata -- overall I am very happy with both the Drobo product, and this role this plays in it.

It was so small than my imagination. Super fast. Super stable. Low heat. You may choice the Crucial m4 but the plextor m5m has higher performance and also higher stability. I won't write a harangue for it. Just let it in your cart, you will never regret.

I bought an Intel NUC unit, and was really excited about how small it was and everything. I paired it up with this zippy little mSata drive and couldn't be happier. Breaths life into the Celeron that is powering the device. VERY low power consumption.

I grabbed this for a fast cache drive for the drobo 5n and it works great. I haven't had any problems with compatibility. I plan on building an Intel NUC with the 256G version because of the great performance I've seen.
