Flagship 7400MB/s! KLEVV CRAS C930 M.2 2TB unpacking

KLEVV has an extensive range of SSD products that cater to various user needs. The product line includes entry-level PCIe 3.0 x4 SSDs such as CRAS C730, C720, and C710, as well as three PCIe 4.0 x4 SSDs: the high-end flagship CRAS C930, the C920, and the mainstream C910. These SSDs come in different capacities, prices, and performance levels, meeting the installation needs of casual gamers and serious gamers alike.

Previously, buyers had to choose whether to purchase an M.2 SSD with or without a heat sink. However, with many DIY motherboards now coming equipped with M.2 heat sinks as standard, this choice has become less important. Nevertheless, for gamers looking to upgrade their PS5 consoles, opting for the version with a heat sink is necessary. The CRAS C930 offers players this choice, with an included aluminum fin heat sink that can be used or not, depending on the installation platform.

The KLEVV CRAS C930’s outer box features key specifications and a product image, as well as the Attachable Heatsink logo on the upper right. This logo indicates to players that the heat sink is not pre-installed on the SSD, giving players the option to decide whether or not to install one.

Inside the box, you will find the CRAS C930 SSD, an aluminum-finned heat sink, and a heat sink installation guide.
Attaching the heat sink to the SSD is a straightforward process. Start by placing the SSD in the original bulb and aligning the middle line to ensure that the heat sink does not cover the front gold finger and the rear screws. Then, once the alignment is correct, simply peel off the adhesive protective film to attach the heat sink to the SSD.

The KLEVV CRAS C930 SSD does not have a sticker on its front, and the bottom of the aluminum heat sink uses 3M thermal adhesive. This allows players to attach the heat sink to the SSD on their own. The center of the cover protects the SSD controller and flash memory particles. However, it is important to note that the thermal adhesive is very sticky, and it is not recommended to remove it after attaching the heat sink.

The aluminum fin heat sink features the KLEVV and CRAS C930 branding, while the front of the CRAS C930 SSD is label-free.

Aluminum fin-shaped heat sinks can increase heat dissipation area to ensure the stable operation of SSD without slowing down.

The CRAS C930 SSD is equipped with the InnoGrit IG5236 controller and uses a PCIe 4.0 x4 interface and NVMe 1.4 specification. The drive also supports 8 NAND channels and DDR SDRAM cache, as well as features such as LDPC ECC error correction, global levelling, and AES 256-bit encryption. These technologies ensure that the SSD delivers stable performance, has a durable write life, and provides encryption protection and other functions.

KLEVV offers a 5-year product warranty for the CRAS C930 SSD, with the 2TB capacity having a write life of 1500TBW. This translates to being able to write 821.9GB of data per day for five years, which is more than sufficient for general use. The SSD utilizes four pieces of 3D TLC NAND Flash memory particles and is combined with SK Hynix DDR4 SDRAM H5ANAG6NCJRXNC cache, as well as SLC cache calculation technology in the firmware. This allows the SSD to achieve impressive sequential read and write speeds of 7400MB/s and 6800MB/s, respectively.

Install CRAS C930 SSD M.2 SSD in PS5

Apart from its use in PCs, the CRAS C930 SSD can also be used to upgrade the high-speed, large-capacity SSD space of the PS5. By expanding the SSD capacity, PS5 games can be stored directly on the drive and executed from it, providing a seamless gaming experience with high-speed loading times. With more games being installed, players can enjoy uninterrupted gaming without waiting for long loading times.

For use in the PS5, M.2 SSDs must meet mainstream specifications such as PCIe 4.0 x4, NVMe, Key M, and 2280, with the most critical requirement being the height of the heat sink, which must be less than 11.25mm. The CRAS C930 SSD, which is only 8.7mm in height, including the heat sink, is perfectly suited for installation in the PS5, allowing for the expansion of high-speed game storage space.

The CRAS C930 SSD comes with a heat sink, which is compatible with PS5’s M.2 SSD upgrade specification.

To install the CRAS C930 SSD in the PS5, simply open the side panel of the console and use the screws and washers that were originally locked in the 110 positions. Move these to the 80 positions and lock the SSD in place. With a height of only 8.7mm, including the heat sink, the installation process is quite smooth. After installing the SSD, turn on the power of the PS5 and format it before the drive can be used normally.

CRAS C930 SSD can achieve a read speed of 6475MB/s on PS5.
