Kingston UV500 M.2 SUV500M8/240G 240 GB

Three from the casket

Kingston UV500 M.2 is a new line of solid state drives from the American brand, which, in addition to the M.2-SATA form factor for modern laptops (with the same connector), includes 2.5-inch SATA for desktop PCs and mSATA for older laptops. Moreover, the form factor is the only difference, otherwise all three models are identical.

Back to the roots

Kingston engineers decided to abandon the Phison S11 controller that was used in last year's A400 SSD, and returned to Marvell 88SS1074, which was the basis of the year before last UV400. At the same time, compared to the UV400, the UV500 lost its RAM cache, which negatively affected the write speed of 4K blocks (25,000 IOPS in total). To put it simply, the Kingston UV500 is relatively slow with ultra-small files (although still ten times faster than a hard drive).

Not everyone is equally beneficial

The Marvell 88SS1074 controller assumes a stable sequential read speed of 520 MB / s, but a drop in speed when writing files larger than 4 GB (from 500 to 100 MB / s). Unpleasant, but typical for 3D TLC memory, and if you want to avoid such nuances, if you please, pay extra for MLC. In general, Kingston UV500 is interesting only in M.2-SATA and mSATA formats. Classic 2.5-inch SSDs can be found cheaper and faster, such as the old but still ubiquitous Kingston UV400.
