Low-Profile GL Mechanical Switches
Actuation distance: 1.5 mm
Total travel distance: 2.6 mm (Source)

2.6 mm key travel distance difference between Logitech MX KEYS (1.3 mm - scissor switch keys) and Corsair K70 (3.9 mm - mechanical keys) may not look a lot, but your fingers must travel not only DOWN, but UP too and over edges of keycaps, in order not to stumble on keys, when you move your fingers across keyboard. Total finger travel distance is... (key travel distance + key indentation) x 2:

2.6+ mm for Logitech MX KEYS
7.8+ mm for Corsair K70

Noise (dBA): Mechanical keyboards are uncomfortable, overrated and annoyingly loud (Corsair K70 42.6 dBA) even with O-Ring switch dampeners (Corsair K70 with 40A-R O-Rings 37.8 dBA). It is nearly impossible to use them with voice-activated chat during online gaming sessions or around other people in quiet environments like bedrooms. People will hate you for all that noise. They also ruin immersiveness of quiet scenes in games and when you need to hear hints of sounds, like faint steps behind you. To avoid negative effects on sleep, sound pressure level should not exceed 30 dBA (Nigh Noise Guidelines for Europe by World Health Organization).

Actuation and travel distances (mm): Long key travel distances in mechanical keyboards (~4 mm x down+up = ~8 mm) feels inferior by comparison with scissor-switch keyboards (~2 mm x down+up = ~4 mm). Mechanical keyboard manufacturers know about this and some of them brag, how they reduced it by 25% and how faster it is now. Thin scissor-switch keyboards are twice as fast as mechanical, because even, when key actuates at the same ~2 mm distance, release is instant. Long travel distances and no soft cushion in mechanical keyboards results in hurt fingers after longer gaming sessions, because of frequent attempts to reach contact point as fast as possible, which means hitting key's bottom quite hard. Playing intensive games is not like playing some slow, peaceful and calming piano music. If you want to buy mechanical keyboard “for gaming”, you should try it first. Finger travel... DOWN + UP + over edges of keycaps:

Logitech MX KEYS • Scissor • Noise 24.7 dBA • Actuation 1.3 mm • Down+Up travel distance 2.1 x 2 = 4.2 mm.
Corsair K70 • Mechanical • Noise 42.6 dBA• Actuation 1.9 mm • Down+Up travel distance 4.0 x 2 = 8.0 mm.

LED Illumination (White vs RGB). Scissor swich keyboards usually use White LEDs for backlight illumination. Mechanical “gaming” keyboards usually use RGB LEDs. You can set different colours for different keys with RGB LEDs, but you will not be able to set pleasant and evenly white illumination for whole keyboard. There will be noticeable and inferior looking colour distortions. To achieve even and similar white light quality, mechanical keyboards should use RGBW LEDs.

2014-08WASD • O-Ring Switch Dampeners€15

0.4mm Reduction - Blue
0.2mm Reduction - Red

"Bottoming out" is a term used to describe when a key stroke is pressed all the way down, where the stem of the switch hits the inside of the switch casing. This causes a "clack" from the collision on mechanical keyboards. Switch sound dampeners are soft rubber O-rings that can be installed onto every single keycap stem to cushion the landing of the switch by stopping the key stroke just short of the point of bottoming out. This also very slightly reduces the max travel distance of the switch. (0.2-0.4mm of 4mm total travel distance. Varies by O-ring type.) This modification is popular among mechanical keyboard owners from around the world. Since most people will bottom out at least a fraction of their keystrokes, the switch sound dampeners will cut away extra noise giving your mechanical keyboard a consistent sound output while typing. The added shock absorption can also help with finger fatigue during long typing sessions. Made of industrial grade EPDM rubber which has much better resistance to cracking and tearing than nitrile or silicon rubber. Fits firmly onto the stem of Cherry MX keycap.

Windows mouse settings...

Extra mouse buttons: Proper gaming mouse is like HOTAS Joystick, it allows you to keep left hand on movement keys (W,A,S,D,SHIFT,SPACE) at all times, while performing most basic FPS functions (shoot, aim down sight, throw grenade, melee attack, crouch, prone, draw side gun, ...). This requires more than 5 buttons. True gaming mouse must have at least same amount of action buttons as a standard gaming controller which is 14 (A, B, C, D, LS, RS, LT, RT, LB, RB, D-PAD Up, D-PAD Right, D-PAD Down, D-PAD Left). Logitech G700s with 13 programmable buttons comes very close to perfection. Extra buttons is exactly, what makes mouse a "gaming mouse", because extra buttons gives advantage over other players. Of course, higher DPI, faster pool rate, memory profiles and scripting makes mouse a "gaming mouse" too.

DPI and muscle memory: It is important to make sure, that mouse sensitivity in Windows is the same as in the Game, because it allows you to move windows cursor to a specific location or move in-game target onto the enemy without conscious effort.

DPI higher than 6400 is mostly a marketing gimmick, because many games does not support DPI higher than 3200. You can use low sensitivity settings and 10.8 inches swipe on the mouse pad to turn 360 degrees in the game. Sensitivity of 1600 DPI is most convenient for that now:

In Windows:

a) Open Control Panel -> Mouse -> [Pointer Options] tab and
b) Set pointer speed at marker 3 (11 markers: from 0 to 10)

In game:

1. Most games allow to set 360° Turn = 10.8" swipe.
2. With 80° in-game Field on View (FOV) and 1920 pixel wide monitor it allows to shift in-game world with 1/2 pixel precision exactly. This gives two advantages in FPS games:
a) Partly removes "pixel snapping" effect and results in smooth and high quality precision movement when sniping far away targets, which occupies 1-2 pixels on the screen.
b) Removes the need to use medium or long-range scopes in FPS games when using high precision weapons, when aiming at far away targets, because "pixel snapping" is no longer screws precision and forces you to miss.

Use mouse-sensitivity.com website to convert distance (10.8") and mouse DPI (1600) into in-game sensitivity value.

Solid State Drives (SSD) for OPERATING SYSTEM. SSDs provide peak performance for booting and high read and write performance to supporting computing that requires enhanced multitasking capabilities. HDDs provide the lowest cost per gigabyte. SSHDs provide a cost per gigabyte that’s just slightly higher than HDDs.

Seagate • IBM • Western Digital • 60 EUR

Solid State Hybrid Drives (SSHD) or Hard Disk Drives (HDD) for DATA. HDDs are the workhorses when it comes to sheer capacity and how much data can be stored. SSHD technology also offers maximum capacity points at affordable price points while SSDs are only affordable at lower capacities. High-capacity SSDs are extremely expensive. On the other hand, an SSHD can provide near–SSD performance for booting, launching, and loading data. HDDs usually provide ample performance for the majority of PC platforms available today.

RAID Level 0 (Striping) (Greitis):

RAID kontroleris padalina informaciją į blokus (pvz. po 4KB, 64KB arba 128KB) ir rašo juos į skirtingus diskus. Tarkime, jūsų kompiuteryje yra vienas 40GB diskas. Maksimalus greitis, kuriuo šis diskas gali perduoti duomenis, yra 150Mbps. Tačiau pagrindinė plokštė sugeba duomenis priimti kur kas greičiau. Todėl jeigu įstatote antrą diską ir įjungiate duomenų perdavimą per RAID kontrolerį, plokštė perduoda informaciją RAID kontroleriui, kuris padaliną ją per pusę ir tuo pačiu metu rašo į du diskus po 150Mbps. Tokiu būdu sistema gali paduoti ir traukti duomenis per RAID kontrolerį dvigubu (teoriškai) greičiu t.y. 300Mbps (2x150Mbps).

Privalumas: Duomenų perdavimas yra 32-37% didesnis už vieno disko greitį.
Trūkumas: saugumas - jeigu nors vienas diskas suges neatstatomai, neteksite duomenų abiejuose diskuose.
Talpa: Loginio disko talpa yra du kartus didesnė už mažesniojo disko talpą (pvz. naudojant du 40GB talpos diskus, Loginio disko talpa bus lygi 80GB).
Pastaba: greičiui padidinti galite naudoti du mažesnės talpos, bet greitus diskus (10000rpm). Tai labai patogus sprendimas dizaineriams, dirbantiems su dideliais failais t.y. situacijose kada kietas diskas yra dažnai maksimaliai apkraunamas. Jeigu su kompiuteriu žaidžiate kortomis ir landžiojate po internetą tai RAID 0 jums nereikalingas.

RAID Level 1 (Mirroring) (Saugumas):

RAID kontroleris paraleliai dubliuoja informacijos blokus (pvz. po 4KB, 64KB arba 128KB) abiejuose diskuose. Duomenų perdavimo greitis nesikeičia.

Privalumas: Jei vienas diskas fiziškai suges, antras diskas veiks toliau. Pakeitus sugedusį diską, jame bus padaryta gerojo disko informacijos kopija.
Trūkumas: Kaina - vietos praradimas dėka informacijos dubliavimosi (pvz. naudojant du 80GB diskus, Loginio disko talpa bus lygi 80GB).
Talpa: Loginio disko talpa yra lygi mažesniojo fizinio disko talpai.
Pastaba: saugumui padidinti galite naudoti didelės talpos lėčiau besisukančius diskus (5400rpm). Tai patogus sprendimas saugoti svarbius archyvus.

RAID Level 0+1 (Striping + Mirroring) (Saugumas ir Greitis):

RAID kontroleris dubliuoja ir padalina informacijos blokus keturiuose diskuose. Šiai konfigūracijai reikia keturių diskų. (pvz. naudojant keturis 40GB talpos diskus, Loginio disko talpa bus lygi 80GB). Šiuo atveju galite naudoti didelės talpos standartiniu greičiu besisukančius diskus (7200rpm).

Privalumas: sistema veikia 20-32% greičiau, o sugedus vienam diskui informacija bus saugi. Informacija bus apsaugota ir sugedus dviem diskams - išskyrus atvejį jei tuo pačiu metu suges du diskai su vienoda informacija.
Trūkumas: kaina - vietos praradimas dėka informacijos dubliavimosi (pvz. naudojant keturis 40GB diskus, Loginio disko talpa bus lygi 80GB).
Talpa: Loginio disko talpa yra dvigubai didesnė už mažiausiojo fizinio disko talpą.
Pastaba: Šiuo atveju galite naudoti didelės talpos normaliai besisukančius diskus (7200rpm).

RAID Level 5 (Striping + Parity) (Saugumas ir Greitis):

RAID kontroleris padalina informacijos blokus per visus diskus ir vieną bloką (parity) palieka kontrolinei sumai. Šiai konfigūracijai reikia ne mažiau nei 3 diskų. kontrlinė suma visada užims vieno disko didį.

Privalumas: Su 3 diskais sistema veikia taip pat greitai kaip ir RAID 0 (kuo daugiau diskų, tuo teorinis greitis didesnis), o sugedus vienam diskui, trukstamą informaciją galima atstatyti. Tai viena iš populiariausių RAID konfiguraciju.

Batteries for alternative energy systems are available in 2, 4, 6, and 12 volts

1) RV / Marine / Golf Cart : RV or Marine type deep cycle batteries are basically for boats & campers and are suitable for only very small systems. They can be used but do not really have the capacity for continous service with many charge/discharge cycles for many years. Regular or Car type batteries should not be used at all because they cannot be discharged very much without internal damage. A very popular battery for small systems is the Golf Cart battery. They are somewhat more expensive than deep cycle recreational batteries but are probably the least expensive choice for a small system on a budget.

Industrial strength : Flooded, Gel, and AGM sealed batteries

The next 3 types are the heavier industrial type batteries. They are all also considered Deep Cycle and are usually Lead Acid types with much thicker internal plates that can withstand many deep discharge cycles. These next 3 are all designed for alternative energy systems.

2) Flooded types : These are Lead acid batteries that have caps to add water. Many manufacturers make these types for Solar Energy use. Trojan, Surrette, and Deka are probably the most well known. They are reasonably priced and work well for many years. All flooded batteries release gas when charged and should not be used indoors. If installed in an enclosure, a venting system should be used to vent out the gases which can be explosive.

3) Gel : Not to be confused with maintenance free batteries, sealed gel batteries have no vents and will not release gas during the charging process like flooded batteries do. Venting is therefore not required and they can be used indoors. This is a big advantage because it allows the batteries to maintain a more constant temperature and perform better.

4) AGM : Absorbed Glass Mat batteries are in my opinion the best available for Solar Power use. A woven glass mat is used between the plates to hold the electrolyte. They are leak/spill proof, do not out gas when charging, and have superior performance. They have all the advantages of the sealed gel types and are higher quality, maintain voltage better, self discharge slower, and last longer. The Sun Xtender series by Concorde Battery is an excellent example of AGM batteries. They are more expensive, but you usually get what you pay for. You will find this type of battery used in airplanes, hospitals, and remote telephone/cell tower installations. More...
