# MyDigitalSSD BPX 240GB Review — A Budget MLC PCIe 3.0 NVMe from a Defunct Brand (2026)

The MyDigitalSSD BPX 240 GB was one of the cheapest ways to get a DRAM-equipped MLC NVMe SSD in 2017 — and the fact that the company behind it has since disappeared makes it a fascinating snapshot of the early NVMe market.

Quick answer: The MyDigitalSSD BPX 240 GB is a budget MLC NVMe relic from a defunct brand — and at the right used price (think well under $20), it is a perfectly functional boot drive for a retro PCIe 3.0 build or a secondary system where capacity is not a concern. The MLC NAND provides write consistency that no modern budget SSD can match, and the DRAM cache keeps Windows responsive. Buy it as a curiosity or a period-correct component for a 2017-era build. Do not buy it as a daily driver — the 240 GB capacity is too small for modern use, the company is gone, and any modern budget PCIe 4.0 drive will dramatically outperform it in real-world use while actually having a warranty.

## Performance

The MyDigitalSSD BPX 240 GB is rated for 2,600 MB/s sequential reads and 1,100 MB/s sequential writes, with random performance of up to 150,000 IOPS reads and 265,000 IOPS writes. The write IOPS figure is unusually high relative to reads — an atypical profile that multiple reviewers confirmed and that likely reflects the E7 controller's firmware tuning for the small-capacity SanDisk MLC configuration. Independent reviewers at Tom's Hardware and Tweaktown measured throughput consistent with the rated figures, with the BPX placing in the middle of the 2017 budget NVMe pack.

The MLC NAND means the BPX does not suffer from the pSLC cache exhaustion cliff that defines modern TLC and QLC SSDs. Writes sustain at the rated 1,100 MB/s from start to finish, with no performance drop as the drive fills. For the 240 GB capacity, this is less of a practical advantage than on larger drives — the drive fills up quickly regardless — but the write consistency is technically superior to any modern budget SSD. The E7 controller's power draw is higher than modern equivalents, and the BPX was noted by reviewers as having poor notebook battery life compared to competitors like the Intel 600p.

For gaming, the 240 GB capacity is the limiting factor. It holds a modern OS plus perhaps two or three AAA titles before filling up, making it impractical as a primary drive. As a boot drive for a secondary PC or a dedicated OS volume, the BPX remains responsive — the DRAM cache and MLC NAND ensure consistent latency, and the 2,600 MB/s read speed is fast enough that most users will not perceive a difference versus a modern PCIe 4.0 drive in everyday desktop use.

## Endurance, TBW & Warranty

The MyDigitalSSD BPX 240 GB was originally sold with a 5-year limited warranty and an endurance rating of up to 1,400 TBW for the product line, but the 240 GB-specific endurance rating is approximately 350 TBW — the 1,400 TBW figure is the maximum across all capacities and applied to the largest SKU. At 350 TBW, the 240 GB BPX can absorb roughly 190 GB of writes per day for the warranty period — high for the capacity thanks to the MLC NAND. At a typical 30 GB/day pace, endurance extends beyond 30 years. The MTBF is rated at 2 million hours. Critically, MyDigitalSSD is effectively a defunct company — no new products have been released since approximately 2019, and the warranty is unenforceable. Any BPX purchased today should be treated as having zero warranty coverage and no firmware update path.

## Pros and Cons

**Pros:**

- Genuine SanDisk 2D MLC NAND — consistent sustained writes with no cache cliff
- 256 MB DDR3L DRAM cache for consistent random I/O
- AES-256 hardware encryption support
- 5-year warranty was class-leading at launch for a budget NVMe
- Aggressive launch pricing — among the cheapest NVMe SSDs of its era
**Cons:**

- MyDigitalSSD is defunct — zero warranty support or firmware updates
- Only 240 GB — too small for a modern primary drive
- 1,100 MB/s write speed limited by small capacity NAND configuration
- Poor notebook battery life — high idle power draw versus competitors
- Phison E7 platform is dated — PCIe 3.0, NVMe 1.2, 28nm controller
- No heatsink included — E7 runs warm under sustained load


## Verdict

The MyDigitalSSD BPX 240 GB is a budget MLC NVMe relic from a defunct brand — and at the right used price (think well under $20), it is a perfectly functional boot drive for a retro PCIe 3.0 build or a secondary system where capacity is not a concern. The MLC NAND provides write consistency that no modern budget SSD can match, and the DRAM cache keeps Windows responsive. Buy it as a curiosity or a period-correct component for a 2017-era build. Do not buy it as a daily driver — the 240 GB capacity is too small for modern use, the company is gone, and any modern budget PCIe 4.0 drive will dramatically outperform it in real-world use while actually having a warranty.

## Frequently Asked Questions

### Is MyDigitalSSD still in business?

No, MyDigitalSSD appears to be effectively defunct. The company has not released a new product since approximately 2019 and its web presence is dormant. The BPX and BPX Pro were the brand's most well-known products. Any warranty claims on existing drives are unenforceable, and no firmware updates are available.

### Is the BPX 240GB MLC or TLC?

The MyDigitalSSD BPX uses genuine SanDisk 15nm 2D MLC NAND — planar NAND with two bits per cell. This is the same NAND type that powered enterprise SSDs of the era and offers inherently better write endurance and more consistent sustained write performance than the 3D TLC NAND used in most modern consumer SSDs. The MLC NAND is the BPX's single most distinctive feature.

### What is the real endurance of the BPX 240GB?

MyDigitalSSD advertised the BPX product line as having up to 1,400 TBW endurance, but that figure applied to the largest capacity SKU (likely 960 GB or 1 TB). The 240 GB variant's endurance is approximately 350 TBW, which is proportionally consistent with MLC NAND endurance ratings. Some database entries incorrectly apply the 1,400 TBW line maximum to the 240 GB model.

### Does the BPX 240GB have a DRAM cache?

Yes, the BPX 240 GB includes 256 MB of Nanya DDR3L DRAM as a dedicated cache buffer. The Phison E7 controller always requires onboard DRAM. The 480 GB variant uses 512 MB of DRAM. This is not an HMB or DRAM-less design.

### Is the BPX 240GB still usable in 2026?

As a boot drive for a secondary or retro PC, yes — the 2,600 MB/s read speed and DRAM cache keep Windows responsive, and the MLC NAND is more durable than modern TLC or QLC. As a primary drive, no — the 240 GB capacity is too small for a modern OS, application suite, and game library. The defunct brand means zero warranty support and no firmware updates, making it a riskier purchase than even a used Samsung or WD drive.
