With 2TB solid state drives already available in the market and 4TB models announced to arrive pretty soon it's clear that although the price/capacity gap with 3.5" mechanical drives is still quite wide (currently 10TB 3.5" drives have already made their debut) the same no longer applies for 2.5" mechanical drives since as we speak the highest capacity model is a 3TB one. All of the above however are for the consumer market so when it comes to enterprise grade products things change quite a bit since SAS (Serial Attached SCSI) models cost a lot more compared to their SATA siblings. Because of that 2.5" enterprise grade mechanical hard drives still have the "edge" over enterprise grade SSDs in terms of price/capacity and thus many professionals and businesses still choose to go with them for their data arrays. Toshiba recently announced their latest AL13SXBxx 15.000 RPM 2.5" SAS hard drive line and not long after being the first ones to test the 12Gb/s SAS model with us we have the 6Gb/s SAS one.
