We have seen some high capacity PCIe based SSDs but in the 2.5" form factor they have been few and far between.  This will soon change as Solidata will be releasing a 2 Terabyte SSD called the K8 1920E which will be somewhere in the neighbourhood of $5000 when it becomes available.  Each one of the flash storage chips you can see below is a 64GB chip and with 16 on each side you get a full 2048GB of storage.  It uses four of the LSI Sandforce SF-1222 controllers and a Micron JMB393 SATA II RAID-5 controller which is configured to act as a 4 port hub, treating each of the controllers as a separate 512GB SSD.  Once the SSD Review had formatted the drive for use there was a total of 1788GB available for storage which did not support TRIM as it is technically behind a RAID card.  The performance was on par with expectations, keeping in mind the difficulties that SandForce controllers have with incompressible data. This drive will be very expensive but it seems it will be the first product of its type available to be purchased.

"Ever since SSDs were introduced to the retail market back in 07, one of the main complaints has always been capacity. After all, the first SSD releases were only 32 and 64GB. The hopes of one day seeing the performance of an SSD coupled with the capacity of a hard drive has grown and, too many, we think our analysis of the new Solidata K8-1920E 2TB SSD might be welcome news."
