Two silver 2.5 inch SATA SSDs side by side

Gigastone Corporation

Gigastone Corporation 2-Pack 1TB SATA 2.5" internal SSD

SKU CH-X23W-0TJAS

Two 1 TB SATA 2.5" drives with 3D NAND deliver up to 520 MB/s read and 480 MB/s write for faster boots and app loads in laptops or desktops

  • Total capacity1 TB
  • Sequential read speedUp to 520 MB/s
  • Sequential write speedUp to 480 MB/s
  • Interface typeSATA III
  • Form factor2.5 in (6.35 cm)
  • Product typeInternal Solid State Drive (SSD)

Model 1TB (2 Pack)

  • Boots and loads faster with read speeds up to 520 MB/s
  • 3D NAND with SLC cache delivers sustained performance and longevity
  • 7 mm 2.5″ form factor fits laptops, desktops and ultra-slim notebooks
  • Shock and vibration resistant with no moving parts for silent operation
  • Rated for 500 TB written and 1,500,000 hours MTBF

Two-drive kit for desktops and laptops

This pack contains two 1TB 2.5-inch solid-state drives built with 3D NAND. They connect through the SATA interface and fit standard 7mm bays in notebooks, ultra-slim notebooks and desktop PCs. The drives are intended as a direct replacement for mechanical hard disks in consumer systems.

7mm metal chassis and SATA connectors

The 2.5-inch form factor measures 7mm thick and uses the standard SATA data and power connectors found in most laptops and desktops. No heatsink is fitted, so the drives sit flush in tight bays. Shock and vibration resistance protect data when the machine is moved, and the lack of moving parts keeps operation silent.

SATA bandwidth and endurance limits

Sequential transfers peak at 520 MB/s read and 480 MB/s write, which is the practical ceiling of the SATA link. Random 4KB performance reaches 95,000 read and 90,000 write IOPS. The drives are rated for 500 TBW and a 1.5 million hour MTBF, with idle power as low as 30 mW and active power averaging 2.5W up to a 4.0W maximum.

Questions about this item

What real-world speed does the SATA III 6 Gb/s interface cap at on this 1 TB drive?

Sequential read reaches 520 MB/s and sequential write reaches 480 MB/s, which is the practical ceiling of the SATA III link on this model.

Will the 7 mm 2.5" form factor fit my ultra-slim notebook?

Yes, the 7 mm (0.28 in) height matches the standard 2.5" bay used in most ultra-slim notebooks and desktops.

How do I install the drive and what step do people often miss?

Connect the SATA data and power cables, secure the drive in the 2.5" bay, then initialise and format the new volume in Disk Management before use.
