The 4000E series from GIGABYTE targets users looking for the perfect balance between price and performance. This drive sacrifices some high-end luxuries (like external cache memory) in favor of providing a very fast, practical, and energy-efficient storage drive, giving you a smooth and fast daily usage experience at an affordable cost.
Features of the GIGABYTE Gen4 4000E SSD
This drive offers a range of features that make it an excellent economical choice, with its features distributed as follows:
Excellent speeds for daily tasks and gaming (4000 MB/s)
Despite being from the economical fourth generation, the drive offers a sequential read speed of up to 4000 MB/s, and a write speed of up to 3900 MB/s. These speeds far exceed those of third generation drives (Gen3), ensuring you a fast boot for the operating system, short loading times in games, and instant response for programs and applications.
DRAM-less design and energy efficiency
To maintain the economical price, the drive comes without external cache memory (External DDR Cache: N/A), relying instead on modern controller technologies to achieve its speeds. This design directly contributes to reducing power consumption; it does not exceed 4.4 watts under maximum load, making it a great friend to laptop batteries.
1 terabyte capacity in a very compact size
The drive comes with a storage capacity of 1000 gigabytes (1TB) and it is an excellent and ideal space for the average user to store the operating system and a good collection of games and files. It also features a standard design M.2 2280 with a thickness of no more than 2.3 mm, ensuring compatibility with all motherboards and slim laptops easily.
Excellent lifespan and reliability (320 TBW)
To ensure the security of your data, the drive comes with an average time between failures (MTBF) of 1.5 million hours, and a write amount of 320 terabytes (TBW) supported by a limited 3-year warranty. You can also continuously monitor the health and performance of the drive through the GIGABYTE SSD toolbox.
Who is this hard drive for?
