Last month, Crucial debuted the MX300 solid state drive line with a 750 GB model, offering impressive capacity and performance for the price thanks to 3D NAND chips jointly produced by Intel and Micron.

Crucial is now expanding the MX300 line-up with three more models, packing capacities of 275 GB, 525 GB, and 1 TB. The lowest capacity model is a very affordable $69.99, with prices increasing near-linearly up to the 1 TB model priced at $259.99. Here's a full breakdown of the offerings:

  • 275 GB - $69.99 - $0.25/GB
  • 525 GB - $129.99 - $0.25/GB
  • 750 GB - $189.99 - $0.25/GB
  • 1 TB - $259.99 - $0.26/GB

All but the 275 GB drive pack the same performance: sequential read/write speeds are listed as 530 MB/s and 510 MB/s respectively, while random performance comes in at 92k IOPS reads and 83k IOPS writes. The 275 GB drive features reduced sequential write performance of 500 MB/s, and reduced random read speeds of 55k IOPS.

All four drives are available now in 2.5-inch SATA form factors, although M.2 variants will be coming in late August. The entire series is backed by a three year warranty with rated endurance of 220 TB.
