Welcome to a Digital Camera Battery specialist of the Hp Ac Adapter
What's inside the HP Z1 workstation varies depending on the configuration you choose. We tested the B4F79PA model, which has an Intel Xeon E3-1245 CPU. This is a Sandy Bridge chip that has four cores plus Hyper-Threading, and a standard frequency of 3.3GHz. It supports error correction code memory and ships with 8GB off DDR3-1600, ECC memory (via two 4GB modules). The graphics adapter is an NVIDIA Quadro 500M, which is an entry-level adapter designed for all-in-one use — it's not an adapter for gaming, but for running specific design applications.
Storage in the B4F79PA is handled by a single solid state drive (an Intel SSDSA2BW160G3H), which is a 2.5in, 3Gbps SATA2 drive with a 160GB capacity. Up to two, 2.5in SSD drives can be installed in the Z1's sole drive bay, or it can be used to house one 3.5in hard disk drive with battery like HP F1781A Ac Adapter , HP 298238-001 Ac Adapter , HP OmniBook 2106 Ac Adapter , HP OmniBook 6050 Ac Adapter , HP Pavilion N5500 Ac Adapter , HP Pavilion n6400 Ac Adapter , HP Pavilion XF125 Ac Adapter , HP Pavilion ZT1130 Ac Adapter , HP ED495AA Ac Adapter , HP 391173-001 Ac Adapter , HP ACC23H Ac Adapter , HP Pavilion DV1000 Ac Adapter . The interface for these drives supports a speed up to 6Gbps, but the SATA interface for the optical drive supports up to 3Gbps.
In CrystalDiskMark, the solid state drive notched up a read rate of 236MBps (megabytes per second), and a write rate of 173MBps. In our own file transfer tests, where we duplicate data on the disk, the drive averaged 117MBps. These are good results overall, especially the write rate. However, there are even faster solid state drives out there, such as Crucial's m4, for example.
In our Blender 3D rendering and iTunes MP3 encoding tests, the Z1 recorded times of 18sec and 38sec, respectively, which are typically results that a high-end consumer PC can achieve, such as the Dell XPS One 27, which, coincidentally, is also an all-in-one, but based on Intel's third generation Intel Core i7 CPU. Media transcoding tasks were performed efficiently, with the Z1 taking 35min to convert a DVD file to an Xvid file using AutoGordianKnot and 7min to convert a DVD file to an MKV file using Arcsoft Media Converter 7. Again, these results are similar to what the Dell all-in-one achieved.
The Quadro 500 graphics adapter in the Z1 wasn't as good in 3DMark06 as the mid-range GeForce GT 640M in the Dell. The Quadro 500 recorded 7378 in this benchmark, whereas the GeForce 640M GT got 12893. However, the latter is tuned for gaming, not for productivity applications like the Quadro adapter. The Quadro 500 drives a screen that has a native resolution of 2560x1140 and it looks superb. Photographers and users who edit videos should appreciate its high brightness, contrast and clarity, and its viewing angles are also very wide (it's an IPS panel). The unit doesn't swivel, but it does tilt, and this can be helpful in trying to rid the screen of reflections — the glossy panel is susceptible to reflections from room lights in particular.
