The Mushkin Chronos and Chronos Deluxe are both Sandforce 2881 based SSDs from Mushkin. The only difference between the two is their NAND Flash: Intel asynchronous 25Nm for the Chronos vs Toshiba 32Nm Toggle Mode for the Deluxe. The 32Nm Toggle NAND supports far higher write speeds as can be seen from this direct performance comparison of the two drives. Overall the Chronos Deluxe performs slightly above expectations for a Sandforce SF2281 drive, it has reasonable read speeds but still struggles when faced with writing incompressible data. With an effective (real world) speed of 347 MB/s the Chronos Deluxe lags the group leaders by 50% and as such there are far better drives, such as the Samsung Evo, available in today's market. [Jan '14 SSDrivePro]

The 250GB Crucial BX100 SSD is the value orientated variant of Crucial's M range of SSDs. The BX100 uses the same NAND as its premium MX200 sibling but the BX100 uses a Silicon Motion controller as opposed to the Marvel controller found in the MX range. Feature wise the BX100 is missing SLC caching and there is no hardware encryption (so security frameworks such as windows Bitlocker will operate less efficiently). In terms of I/O performance the BX100 looks promising. Comparing the BX100 and MX100 shows that the newer BX100 may be faster than its predecessor but as yet there are insufficient user benchmarks to draw any definitive conclusions. The BX100 has only just started hitting the shelves so there's plenty of room for price reductions from its already reasonable price tag. I will revisit this review when I have more performance data for the BX100. [Jan '15 SSDrivePro]
