Supports Four Compatible Memory Cards
The number of compatible memory card supported by the ThinkCentre E73 SFF is more than most PCs of this spec and age. This personal computer supports an SD compatible memory card, which is the most frequently supported compatible memory card supported by computers of this age and spec. The compatible memory cards "MMC", "SDHC" and "SDXC" are also supported by this Lenovo personal computer.
Computers that have been around for more than a year have widths of between 33mm and 510mm, and the average width is 180mm. At only 160 millimeters, the ThinkCentre E73 SFF is fairly narrow compared to most of the other computers that have been around for a comparable time to the ThinkCentre E73 SFF.
4 Reasons Against
Only HDD Storage Medium
The storage speed of this computer is HDD, which is the most frequently found storage medium on medium processor core personal computers that have been available for a comparable time to it. A Hard Disk Drive (HDD) is the traditional storage method for computers. A HDD stores the information on magnetic disks. HDD drives are cheap, but they are slower than Flash and SSD bases storage systems.
Desktop computers with a faster storage speed that might be worth looking at include the W530 (£1,035.64) (SSD), or the M740 (£1,513.20) (SSD) both from Fujitsu.
Only 11 On-Board Graphics Adapter DirectX Version
This PC supports a 11.1 on-board graphics adapter DirectX version, which is the most commonly supported on-board graphics adapter DirectX version on similar spec personal computers that have been available for a comparable time to it.
Only Has One Memory Slot
The ThinkCentre E73 SFF has a greater number of memory slots than most medium processor core personal computers that have been around for a comparable time to it. The most commonly found memory slot is 4x DIMM, but this memory slot is not found on this computer. The memory slots 2x DIMM are also found on this personal computer.
Only One 3.5" Bay
Most comparable spec PCs that were released more than a year ago have between one and seven 3.5" bays, including the ThinkCentre E73 SFF which has one 3.5" bay.
