Quotes from the Reviews - What People Say about:

Boot

Boot:
"My restart and boot up are ridiculous."
_
"Got a boot error after swapping the disks, ran my Win7 install disk to automatically repair errors..."
_
"No more spin up noises and overall sound from traditional hard drives, boots up scary fast, editing in photoshop has become much less time consuming and just an overall solid piece of technology."
_
"Two important features about the Crucial M550 2.5 7 mm SATA-III 6 GB s 1.0 TB SSD stand out: 1. it has power capacitors typically found in enterprise SSDs so that in the event that Microsoft Windows 8.1 freezes, locks up, or crashes, then it will preserve the power on the SSD for a brief period of time so it is safe to cut the power on your PC without destroying the SSD and rendering your PC unable to boot the operating system, 2. it has RAIN or Redundant Array of Independent NAND technology which acts like RAID-1 to make a bit-perfect duplicate backup of your data including your desktop operating system, installed software applications and settings, and your user data in the event that one or more of the NAND chips fails."
_
"It is very fast boot time is like 10 seconds now it's ridiculous."
_
"Boot times prior to installing the M550 were easily in the 30-45 second span."

_

Read

Read:
"Only problem is now sometimes I can't read the hints and tooltips."
_
"It lasted 5 months.. Read trouble, running slow.."
_
"The second one dead on arrival: Read Error detected by simple checks and after an I O error while restoring my image."
_
"The old hard drives had some scary specs with the read head being so close to the media that was spinning at phenomenal speeds."
_
"Unfortunately, the write speed has never exceeded 430 mb s and read speed never went above 500 mb s."
_
"Read write errors, then total drive failure after 3 days."
_
"I'm using mines in IDE mode for maximum reliability of my PC system and yet it runs really good (approx 270MBs write, 340MBs read)."
_
"Time will tell if the drive will keep this performance consistence over time but I don't think it will degrade for what I have read in other sites."
_
"AS SSD used to benchmarkM4 - connected to onboard Gigabyte GSATA SATA ports(AHCI on) - I get around 150MB s seq read and 50MB s seq writeM4 - now connect to onboard Intel ACHI9 matrix controller (ACHI on) - I get around 264MB s seq read and 65MB s seq writeSo just changing controller gave me speed bump, now to the new M550M550 - connect to onboard Intel ACHI9 matrix controller (AHCI on) - I get around 264MB s seq read and 245MB s seq writeSo, there you have it, M550 results pretty much inline with what has been said online in reviews and tech forums, no speed bump for reads, but writes way better, even on an old system."
_
"The read write speeds are great."
_
"buy it at a good price517mb s read and 477mb s write by ssd benchmark"

_

Windows

Windows:

"After building my powerhouse computer, I had a somewhat disappointing Windows Experience Index score of only 5.9, due to my slow Seagate SATA 3 6GB s 7200 RPM drive dragging down my system."
_
"note: One of the optimizations is to disable windows search... That is ridiculous since I'm not sure how any one who uses a PC most of the day like me can live without windows search!"
_

_
"Worked excellent no problems setting up or installing windows"
