Two matte black 2.5 inch SSDs side by side

Gigastone Corporation

Gigastone Corporation 8400 Game Turbo 2-Pack 256GB internal SSD

SKU CH-1R5Q-MDEPB

Two 256 GB SATA internal SSDs deliver up to 540 MB/s reads with 3D NAND and SLC cache for faster boot and load times

  • Device TypeInternal Solid State Drive (SSD)
  • Used ForConsumer
  • Form Factor2.5"
  • Capacity512GB (256GBx2)
  • Memory Components3D NAND
  • InterfaceSATA III

Options 256GB (2 Pack)

  • Sequential read up to 540 MB/s cuts boot and load times
  • 3D NAND with SLC cache delivers sustained speed and drive longevity
  • 7 mm 2.5″ form factor fits laptops, desktops and ultra-slim notebooks
  • 128 TB written endurance and 1,500,000 hour MTBF back long-term reliability
  • Two 256 GB drives give 512 GB total capacity in one pack

Two-Drive Kit for Everyday Upgrades

This two-drive kit delivers 512GB total capacity using a pair of 256GB 2.5-inch SATA SSDs. Designed for consumers who want faster boot and load times, the drives suit laptops, desktops and ultra-slim notebooks with a 7mm drive bay.

SATA III Throughput Ceiling

The SATA III interface caps real-world sequential transfer at roughly 540 MB/s read and 480 MB/s write. Random 4K performance reaches 95000 IOPS read and 90000 IOPS write, so the drives saturate the link before the controller becomes a bottleneck.

128 TBW Endurance Rating

Each drive is rated for 128 terabytes written and a 1.5-million-hour MTBF, using 3D NAND with an SLC cache layer. That endurance figure is the primary guide for deciding whether the kit matches your workload.

Questions about this item

Should I pick the 256 GB single drive or the 2-pack for 512 GB total?

The listing is a 2-pack of 256 GB drives giving 512 GB combined capacity, so you receive two separate 2.5 inch SATA SSDs rather than one larger unit.

What does the 540 MB/s read figure mean once the drive is installed?

That is the maximum sequential read speed over SATA III; real-world OS boot and application loads will be faster than a hard drive but limited by the SATA 6 Gb/s interface ceiling.

Which interface does this SSD use and what does it cap in practice?

It uses the SATA III 6 Gb/s interface, which caps practical throughput around 540 MB/s read and 480 MB/s write regardless of the 3D NAND and SLC cache technology.
