MyDigitalDiscountBP5e SSD Conclusion
IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete. Please do not base any purchase solely on our conclusion, as it represents our product rating specifically for the product tested which may differ from future versions. Benchmark Reviews begins our conclusion with a short summary for each of the areas that we rate.
Long sequential writes are the obvious weak point of the MyDigitalDiscount MDS7-BP5e-0256G SSD, and by “long”, I mean “over about 4GB”. With smaller transfers, you’ll see write performance of 400MB/s or slightly more, due to the NANYA cache memory chip. Once you run off the edge of the cache and are writing directly to the TLC NAND, performance plummets…but this is a well-known weak point of TLC NAND.
So how much difference will this make in day to day usage? Probably not much: as you can see from most of the benchmark results, overall performance is excellent, especially at the price. The only time most users would run into the slow write problem is when transferring a lot of data from another device.
The BP5e 240G SSD is part of MyDigitalDiscount’s new “Bullet Proof Eco 5” family, and as of this writing comprises the least expensive 240G, 480G, and 960G drives I can find. You’ll pay significantly more for the same capacity in competitive drives…for now at least. And most of the performance deficits expected in this class of drive are now gone due to the new PHISON controller, which corrects all the performance and consistency problems I saw in products with the older 3109 controller.
The lower endurance of TLC NAND– how many times it can be erased and re-written– is reflected in the drive’s 3-year warranty, which is on the low side compared to its competition; the service life of the drive is an unknown since MyDigitalDiscount doesn’t publish any durability data. Still, with the continually plummeting cost of consumer SSDs, it’s unlikely this will be an issue during the drive’s typical service life, and at the end of the three-year warranty, you’ll likely be able to pick up terabyte SSDs for under $100 anyway.
This is the plainest-looking SSD I’ve ever tested, but even the fanciest are distinguished only by pretty labels and perhaps a brushed surface finish. This drive will be buried deep in the bowels of your system, so who really cares what it looks like? The clever snap-together construction and quality of the internal PCB speak well of the drive’s physical quality.
As usual with MyDigitalDiscount SSDs, no utility software is included, all in the name of keeping the price down. I’d still like to see some system-migration software to help consumers move their existing Windows installations to this new media.
So at the end of the day we have a very low-cost drive that will return exceptional performance, at or near the limits of the SATA 6G interface, in the majority of consumer and enthusiast applications. The tradeoffs are limited iOPS and long sequential write performance, and the possibility of a lower service life, all due to the same TLC NAND that helps keep the price down. For the vast majority of uses, this is a tradeoff worth making.
As we head into 2016, the MyDigitalDiscount BP5e series of SSDs are available online for: 240GB $64.99 (Amazon), 480GB $124.99 (Amazon), 960GB: $239.99 (Amazon). It’s worth noting that 1TB SSDs have typically fetched a premium, and to find one for under $240 is nothing short of impressive.
