While PCIe Gen 5 NVMe SSDs are setting new storage performance benchmarks, the real-life and application benefits of getting those drives are still not worth the price you are paying for them. It's mostly an early adopters product for now and while we appreciate the speed-up, we would love to see the performance transition from synthetic benchmarks to actual use cases.
And you know what's still considered to be quite fast without breaking your wallet? The current-gen PCIe Gen 4 NVMe SSDs. Gen 4 SSDs are now available at very affordable price rates and offer great performance which is why KLEVV has now launched its new CRAS C925 series which are designed & build for mainstream audiences and positioned between the C910 and C930 series which we have tested in the past.
Today, I will be testing the KLEVV CRAS C925 1 TB SSD. The drive features a Gen 4.0 protocol which means that it is future-proof and retails for $66.99 US.
KLEVV CRAS C925 1 TB PCIe Gen4 NVMe SSD
The KLEVV CRAS C925 SSD is part of the CRAS "C" series family which encompasses a lot of price tiers. The Crucial T500 Gen4 SSDs are based on the NVMe SSD form factor and feature the latest 3D TLC NAND flash which offers larger capacities of up to 4 TB, & twice the performance of Gen3 drive.
| Host Interface | NVMe PCIe Gen4x4 |
|---|---|
| Form Factor | M.2 2280 |
| Capacity | 500GB, 1TB, 2TB |
| Controller | Maxio MAP1602 |
| Flash | Strictly-selected 3D TLC NAND Flash |
| Dimension | 80(L) x 22(W) x 3.40(H) mm (with heatsink) 80(L) x 22(W) x 2.15(H) mm (without heatsink) |
| weight | 10g (with heatsink) 7g (without heatsink) |
| Warranty | 5-Year Limited Warranty |
As for the specs, the KLEVV CRAS C925 NVMe SSDs will come with the standard NVMe 2.0 PCIe Gen 5 x4 interface in the M.2 2280 form factor. It will feature 500 GB, 1 TB, and up to 2 TB capacities with a rated speed of up to 7.4 GB/s (Sequential Read) and 6.5 GB/s (Sequential Write). The Maxio Tech "MAP1602" SSD controller is designed to offer a cost-effective yet high-performance DRAM-less solution. Some of the main features of the C925 series include:
- Utilizes the PCI Express Gen4 x4 interface supported by NVMe 1.4
- Supports AES 256-bit Hardware-based Encryption to ensure superior data security
- Intelligent SLC caching algorithm and HMB technology (Host Memory Buffer) for high endurance and performance improvement
- Powerful Hardware LDPC ECC Engine for endurance and retention improvement
- End-to-end data path protection with CRC parity
- SRAM error handling on major memory buffers
- Supports Global Wear Leveling for SSD lifespan extension
- Thermal throttling algorithm to protect the SSD integrity
- Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.)
Note - The 1 TB model that we tested had a peak sequential read speed of 7,400 & a write speed of 6,300 MB/s. The Random Reads and Writes IOPS were rated at 670K/980K IOPS & endurance was rated at 1200 TBW.
The SSD comes in a heatsink-less design but there is a small aluminum heat pad that you can easily place over the SSD for some extra cooling.
| 500GB | 1TB | 2TB | ||
|---|---|---|---|---|
| Sequential Read up to (MB/s) | 7400 | 7400 | 7400 | |
| Sequential Write up to (MB/s) | 6200 | 6300 | 6500 | |
| 4K Random Read up to (IOPS) | 670K | 670K | 700K | |
| 4K Random Write up to (IOPS) | 980K | 980K | 1000K | |
| Endurance (TBW) | 600 | 1200 | 2400 | |
KLEVV CRAS C925 1 TB PCIe Gen4 NVMe SSD – Unboxing and Closer Look
The KLEVV CRAS C925 SSDs come in a small package. The package is colored gray/white and features a large picture of the SSD featured on it. The front also lists down some features such as capacities, maximum read speeds, PCIe 4.0 NVMe M.2 form factor, and the 5-year limited warranty.
The KLEVV CRAS SSD series box includes a warranty booklet and the SSD itself. All drives are held within a plastic shell container.
Out of the package, all KLEVV CRAS SSDs come in the standard M.2 2280 form factor and feature a black PCB which is great since some mainstream drives come with blue-colored PCBs.
All of the NAND Flash chips along with the MaxoTech controller are situated on the front. Being a single-sided design means that the SSD will run a bit cooler since users don't have to worry about heat from any components on the other side.
The drive we received was a non-heatsink variant and you shouldn't worry much about heat since this is a mainstream product that won't get too hot or throttle that much. The aluminum heat pad should provide decent cooling. The front features two ESSENCORE "ENFFGP8NC4GR-HR" 3D NAND Flash modules and the MaxioTech "MAP1602A-F3C" controller. There are two DRAM slots left over for the 2 TB variant.
Test Setup
Our test platform for this review consisted of an Intel Core i9-13900K processor which ran at stock clocks on the MSI Z790 ACE motherboard. The platform was coupled with 32 GB of DDR5 memory from G.Skill (Trident Z5/ 16 GB x 2) and the MSI MEG Ai1300P PSU. For graphics, I used the MSI GeForce RTX 4090 SUPRIM X. This rounds up as a high-end platform for tests with modern-day SSDs. The MSI Z790 ACE specifically houses a single Gen 5.0 x4 NVMe slot that sources its lanes from the Raptor Lake CPU.
