Plextor M5M 256GB Mini-SATA (mSATA) MLC Internal Solid State Drive (SSD) PX-256M5M

Pros: Works fine, very quick drive. I installed it as a boot drive into a Lenovo Y500 notebook, didn't feel like overpaying for their 16GB SSD so I ordered without. Instantly recognized. Boot time is very quick, SATA 6Gb/s and seems to be using most of it. No blue screens or errors. Very solid product. Good size for a boot drive and seems to be at the value price point. I didn't sit there and try to time my boot time from hitting the power button, but the psychedelic Windows logo doesn't finish. Boot also does seem faster than my Workstation which boots from a 256GB Samsung 840 Pro. I did get it from newegg, but at $209.

Cons: Though it never said they were included it would be nice if the package also had 1, maybe dare I say even 2 or 4, M2x3mm screws to secure the drive into the slot. Come on - they cost a whole 20 cents retail and probably 1/2 a cent to manufacture. They cost more to ship than they are worth, and for $200+ people should not have to wait for or initiate a second delivery to be able to close their notebook and use their product.

Overall Review: It took a while to track down the spec for the screws. They are standard and are also used to secure the WLAN cards in the notebooks. Drive is great I would recommend it. Great option for all those stuck with Windows 8 notebooks and have an mSATA slot. Good size for Windows 7 with assorted applications.

Pros: 128GB for just a little over a dollar a gig. Amazing read write speeds. Windows 7 Ultimate x64 boots in approx. 22 seconds including POST.

Cons: If only it were bigger, but otherwise none at all

Overall Review: If you plan on going SSD please take your time with installing and also grab a HDD to store the bulk of your data on. Do not installing the HDD until after you install your OS

Pros: Speed, low voltage compared to some others, which translates into less heat and better battery performance, Doesn't use the Sandforce controller

Cons: None yet

Overall Review: Installed on an Acer M5-481 series touchscreen with Win8. Worked first time w/o issues. 1. Create a backup USB drive with Acer utility. 2. Search web for the service manual, it is out there. 3. Remove all screws from bottom of case. Use something plastic to pry the top from the bottom (you will have to open the screen to get around the hinges). 4. Have someone hold the top cover so you don't have to remove the three cables. Replace the msata with new one and remove the HHD cable from socket and place next to socket so you can reclose the laptop (it won't bott without the screws in place). 5. Boot from recovery USB and install windows. 6. Reopen laptop and reconnect the HDD cable. 7. Reboot, using F12 to boot from Msata. Once there, chill for a minute (HDD was not visible for me). 8. Reboot and enter bios (F2), setting msata as 1st boot device. 9. Done! 10. Optional - get to control panel (disk management) and format the old HHD partition after you have copied everything you need from it.

Pros: CrystalDiskMark Before : Seq : Read 182 MB/s Write 177 MB/s 512K : Read 26 MB/s Write 51.4 MB/s 4K : Read 0.3 MB/s Write 1.3 MB/s Now with Intel Smart Response w/ the mSata: Seq : Read 269 MB/s Write 163 MB/s 512K : Read 224 MB/s Write 164 MB/s 4K : Read 24 MB/s Write 41 MB/s

Cons: None

Pros: Great drive, fast, larger than the Mushkin which has only 240 gigs for the same price, the Crucial M4 256G that was also the same price had slower specs. Was able to buy it for 30.00 off from the original price. Didn't even have to do anything to the Lenovo Y400 that I installed it into, the UEFI bios picked it up right away. I was able to get the software NTI echo and it moved windows 8 over no problem. I cannot confirm at this time if the onekey restore has been affected, I clicked on it and it started up but I didn't go as far as trying to reinstall with it.

Cons: No software included to move data/set up bootable drives like the 2.5 SSD drives do, you should be able to register the drive's SN and download them at the manufacture's website. *Take a hint Plextor and do this, NOW before the others catch on!

Overall Review: So far, so good, Glad I went with Plextor! I know that all mSata drives are considered OEMs but really guys, you should include the software no matter what manufacture you are. I will check back in 6months to a year and let you know how its working still. If you hear from me again its either a really bad or really good product =P

Pros: Small form factor SSD. Works with my Asrock Z87E itx mother board perfectly.

Cons: None that I have seen.

Overall Review: Took advantage of a clean OS SSD install to minimize clutter in my build. No, you can't see it since it is under the mother board. Love it.

Pros: First of all, it now comes with two screws! I read the previous review that mentions no screws included and was trying hard to find those M2X3mm screws. Apparently Plextor is listening to its customers, a good sign! Drive installed in a few minutes, but I have to go to disk manager to format it in order to see the drive. After that, I used Paragon migrate OS to SSD to transfer my OS. Super easy and it takes less than 10 minutes to finish the job. (Even drive letters were changed automatically so the SSD is the local C drive after running the program) I use CrystalDiskMark to measure the speed and it is pretty close to the specs. (>90% of the UP TO speeds claimed)

Cons: Does not come with any instruction, manual, or even a short guide (for upgrading firmware, using tools etc).

Pros: Very reasonably priced. Reliable. Fast. Haven't had a single issue.

Cons: Doesn't come with any screws with which to secure it. I salvaged one from another place in my laptop that I deemed "unnecessary." I'm not sure specifically what type of screws are used, but a quick internet search should get you what you need.

Overall Review: ATTO Disk Benchmark results: Write: 316 MB/s Read: 538 MB/s Advertised speeds: Write: 310 MB/s Read: 540 MB/s Close enough for me!
