3D NAND Flash for Enhanced Reliability and Power Efficiency

Slim S55 applies the advanced 3D NAND flash that enables higher reliability and better power efficiency than traditional SSDs equipped with 2D NAND flash. Powered by SATA III 6 Gbps interface, the S55 is able to deliver incredibly high transfer speeds that enable short boot time, fast application loading and quick file processing.

Built for Multitasking

Equipped with original controller and selected NAND Flash, the S55 guarantees high stability and longer lifespan. The SSD is ideal for heavy users to process large files and demanding programs.

Multiple Techniques Supported

The S55 is 7mm thin and vibration-proof since it contains no moving parts. Built with Bad Block Management, S.M.A.R.T. monitoring system and ECC technology, the S55 promises higher reliability and data transmission safety.

    Best drive for the money! MUST BUY! 1gb/s read and 775mb/s write in raid0
    MUST BUY!!!! DO NOT PASS THESE UP, and DO NOT LISTEN TO THE BAD REVIEWS - THEY CLEARLY HAVE THEM SET UP IMPROPERLY!!!Ok so first and foremost, anyone claiming speeds arent withing a few megabytes of rated numbers then there is an issue with the way it is set up in YOUR system, and not a reason for a bad review. First, make sure that the drive(s) are AHCI enabled in BIOS, and not set to IDE or some other setting, and if you dont know what that means or dont know how to do it well then thats also not SPs fault and not a reason to give less than 5 stars. Second, make sure that you are using STATA III cables rated to handle 6gb/s transfer speeds (Notice i said "gb/s" and not "GB/s" BIG difference in those abbreviations). Third, make sure that the SSD has T.R.I.M. enabled in OS and lastly, Forth, make sure the drive is properly aligned (and i dont mean when you install it), especially if you clone your OS onto it and use it as your boot drive. If it isnt properly aligned regardless of the rest of the settings youll be lucky to get anything over what a standard HDD transfers at, if that.Now, with that out of the way, these drives are awesome especially for the money. They cost about half what the comparable Samsung drive or Corsair drive costs, yet performs identically. I tested singled drive, and got 535Mb/s R and 515Mb/s W.Then of course i tested them for the real reason i bought 2 (because lets face it why buy 2 and not use in RAID?) and tested the setup in RAID 0, 4k aligned, AHCI, and got 1Gb/s R and 775Mb/s W. WOW. Just a few megs shy of what my Samsung SSDs performed at. Again, better than expected performance for less than half the cost of the bigger brands.4k reads were 300Mb/s which jumped to over 500mb/s at 8k and 161mb/s writes which jumped to ~300mb/s at 8k. After 32k, write performance was sustained at AVERAGE of 550mb/s peaking at 775mb/s and my reads were at 874 meg/s, however 1 more increment up to 64k and reads were sustained at 1gb/s consistently regardless of block size (64k through 4mb)I didnt rate support because i dont use it nor will i in the future, so.... yeah, but im sure they are fine and do what they can within their obvious limits. Hope this review helps someone, anyone, everyone!
