Review on πŸš€ SP 256GB SSD 3D NAND A55: Ultimate Performance Boost SATA III 2.5" Internal Solid State Drive by Joshua Douglas

Revainrating 5 out of 5

The best drive for the money! MUST BUY! Read 1GB/s and write 775MB/s in raid0

MUST BUY! DON'T SKIP THIS AND DON'T LISTEN TO THE BAD REVIEWS - THEY ARE DEFINITELY WRONG! So first of all, anyone who claims that the speed is not up to several megabytes in nominal numbers, then there is a problem with the configuration on YOUR system and no reason for a bad rating. First, make sure the drives are AHCI capable in the BIOS and not set to IDE or some other setting, and if you don't know what that means or don't know how to do it well, then that's the case too not SP's fault and no reason to give less than 5 stars. Second, make sure you're using STATA III cables rated for 6 Gb/s transfer rates (note that "Gb/s" and not "GB/s" is a BIG difference between these acronyms). Third, make sure the SSD has TRIM enabled in the OS, and fourth, make sure the drive is properly oriented (and I don't mean when you install it), especially if you're going to clone your OS to it and use it as a boot drive. . If it doesn't align properly, regardless of the rest of the settings, you're lucky if you get more than a standard hard drive transfer, if that's the case. Now that that's out of the way, these drives are amazing, especially for the money. They cost about half as much as comparable Samsung or Corsair drives, but perform the same. I tested a single drive and got 535Mbps R and 515Mbps W. Then of course I tested them for the reason I bought 2 (because let's be honest why buy 2 and not use in RAID?) and tested the setup in RAID 0, 4k alignment, AHCI, 1Gb/s R and 775 Mb/s W. WOW. Just a few megabytes less than my Samsung SSDs. Again, better than expected performance at less than half the cost of the bigger brands. 4k read speeds were 300Mbps jumping to over 500Mbps at 8k and 161Mbps jumping to 300Mbps. at 8k. After 32KB, write performance was held at AVERAGE 550MB/s peaking at 775MB/s and my read performance at 874MB/s, but 1 more increase to 64KB and read performance became constant at 1GB/s regardless of block kept size (64 KB). via 4mb) I didn't rate the support because I don't use it and won't use it in the future, so. Yes, but I'm sure they're fine and doing their best within their apparent limits. I hope this review helps someone, everyone, everyone!
