  • SP Solid State Drive 256Gb 2.5" SATA III

  • Product Type: Internal Solid State Drive (SSD)
  • Brand: SP (Silicon Power)3
  • Series: Ace A55
  • Capacity: 256GB
  • Form Factor: 2.5-inch (7mm thickness), making it compatible with most laptops and desktops that use standard SATA drives.
  • Interface: SATA III (6Gb/s), backward compatible with SATA II (3Gb/s) and SATA I (1.5Gb/s).
  • NAND Flash Type: 3D TLC (Triple-Level Cell) NAND Flash
  • Controller: Often features a Phison PS3111-S11 or similar entry-level controller.
  • Cache: Utilizes "SLC Cache technology" where a portion of the TLC NAND operates in faster SLC mode to boost peak write performance. It typically does not have a dedicated DRAM cache, instead relying on Host Memory Buffer (HMB).
  • Sequential Read Speed: Up to 560 MB/s (ATTO), around 500 MB/s (CDM).
  • Sequential Write Speed: Up to 530 MB/s (ATTO), around 450 MB/s (CDM).
  • Random Read IOPS (4KB): Varies, but generally competitive for a SATA SSD.
  • Random Write IOPS (4KB): Varies, but generally competitive for a SATA SSD.
  • Endurance (TBW - Total Bytes Written): Typically rated around 125 TBW to 150 TBW for the 256GB model.
  • MTBF (Mean Time Between Failures): 1,500,000 hours.
  • Operating Voltage: 5V
  • Dimensions: 100.0 x 69.9 x 7.0mm
  • Weight: 63g (max.)
  • Key Features:
    • SLC Cache Technology: For enhanced write speeds and longer lifespan.
    • Bad Block Management: Continuously monitors and replaces bad blocks to maintain system health and improve reliability.
    • TRIM Support: Optimizes performance and prolongs lifespan by managing data deletion.
    • Garbage Collection: Automatically reclaims unused memory space.
    • S.M.A.R.T. Monitoring System: Allows users to monitor the drive's health status.
    • ECC (Error Correction Code) Technology: Ensures reliable data transmission.
    • Shock & Vibration Proof: No moving parts, making it more resilient than traditional HDDs.
    • Low Power Consumption: Contributes to longer battery life in laptops.
    • SP Toolbox Software: Free-downloadable software for monitoring SSD health, running performance tests, and checking detailed information.
    • RAID Ready & NCQ (Native Command Queuing) Compatible.
  • Warranty: Typically 3 years limited warranty.
  • Model Number (example): SP256GBSS3A55S25
