At times, when purchasing a USB flash drive, the cost of postage and packaging actually constitute more of the price than the USB stick itself. However, the Kingston Technology DataTraveler 100 Generation 3 is incredibly compact and an affordable drive that is more than worth the cost of shipping. This flash drive is the most affordable 64GB USB 3.0 drive on the market, touting read/write speeds of 150Mbps and 70Mbps respectively to make it worth every cent.

The Patriot Supersonic is a USB 3.1 drive (compatible with USB 3.0 and 2.0) from one of the most established memory players on the market. However, the manufacturer is a relative newcomer to this segment.
Still, this hard drive rightly deserves a spot on this list, with its a zinc alloy body with aluminum accent and read/write speeds of 380Mbps and 70Mbps respectively. Let’s just say that it’s no slouch. Plus, it also comes with a five-year warranty.

7. Samsung T3 SSD USB flash drive

Best 1TB USB Drive

If you are looking in the premium territory of the best USB flash drives, then the Samsung T3 is worth taking a look at. Not only does it offer absurdly high read speeds of up to 450Mbps thanks to Samsung's own 3D V-NAND technology, but it also comes with a three-year warranty and has a USB Type C connector.
Note that it is much bigger than a traditional flash drive and it does cost about five times a traditional hard drive of a similar capacity. In comparison, a 1TB SSD like the Samsung EVO 850 costs just £240. It comes with V-NAND like the Samsung Portable T1 and it does boast speeds of 530Mbps and 520Mbps in read/write mode respectively. Note that you will need to get a separate enclosure to get it to work with a standard USB port.

8. SanDisk Ultra Fit CZ43 USB flash drive

Small and unobtrusive
Capacity: 32GB | Interface: USB 3.0
If you don't want a USB stick jutting out the side of your laptop or tablet while you use it or having one is simple not ideal – for example, when you’re using it while traveling, then a low-profile USB stick is an excellent choice. Take the SanDisk Ultra Fit CZ43. It’s small and light enough to easily carry around. And, when it's plugged into your laptop, it doesn't stick out much from the body, making it more secure when you’re using it on the go.
That’s not all; it’s also very cheap, at around £10 for the 32GB version, with 64GB and 128GB versions also available. It's not quite as fast as many of the best USB flash drives we mentioned here, but if you want a small form factor USB stick, it's worth the trade-off.

How to choose your USB pendrive?

  • It's not worth looking for memory sticks smaller than 64GB simply because the price difference you pay for two or four times the storage is tiny.
  • Make sure you include delivery price when doing the numbers as quite often you end up paying more for the postage than the drive itself, particularly for low cost models.
  • USB 2.0 is sufficient for smaller capacities but not for bigger ones where write speeds can get sluggish. Larger pendrives (128GB or more) often come only with a USB 3.0 connector.
  • If you plan on moving files to and from portable devices (tablets or smartphones), consider a memory stick with a microUSB connector and a full-size USB one.
  • Avoid buying your memory sticks from vendors with little feedback on auction websites as these drives might turn out to be fake. All the vendors listed are tried and trusted ones.
  • Above 128GB, you might want to consider a SSD if you want ruggedness, portability, versatility and better performance without the cost.
  • Note that the capacities are likely to be lower than stated when they are formatted and mounted on an operating system.

मॉनिटर (Monitor) एक प्रकार की आउटपुट डिवाइस है मॉनिटर (Monitor) को विजुअल डिस्प्ले यूनिट भी कहा जाता है, देखने में आपके टीवी की तरह होता है, लेकिन कंप्‍यूटर के लिये बहुत महत्‍वपूर्ण और जरूरी होता है इसके बिना आप कंम्‍यूटर पर काम ही नहीं कर पायेगें आईये जानते हैं मॉनिटर क्या होता है और मॉनिटर कितने प्रकार के होते है What is Monitor in Hindi

मॉनिटर क्या है - What is Monitor in Hindi 

मॉनिटर कितने प्रकार के होते है - तीन प्रकार के 
  1. CRT Monitor
  2. LCD (Liquid Crystal Display)
  3. LED (Light Emitting Diode)
LCD (Liquid Crystal Display)
कंप्यूटर मॉनिटर एक ऐसी डिवाइस है जो आपके कंप्यूटर के साथ अगर अटैच ना की गई हो तो आप कंप्यूटर का इस्तेमाल नहीं कर सकते हैं क्योंकि आपको वहां पर कुछ दिखा ही नहीं दिखाई नहीं देगा LCD (Liquid Crystal Display) कंप्यूटर मॉनिटर का जो डिस्प्ले होता है वह बहुत पतला होता है और यह पतले फिल्म ट्रांजिस्टर लिक्विड क्रिस्टल डिस्प्ले का बना होता है Liquid Crystal Display को LCD के नाम से भी जाना जाता हैं यह Digital Technology हैं जो एक Flat सतह पर तरल क्रिस्टल के माध्यम से आकृति बनाता हैं यह कम जगह लेता है यह कम बिजली की खपत करता है


CRT Monitor
जबकि जो पुराने मॉनिटर होते थे वह कैथोड रे ट्यूब (Cathode Ray Tube) के बने होते थे इनकी गहराई लगभग स्क्रीन के साइज के बराबर ही होती थी और यह बिजली भी बहुत खर्च करते थे अधिकतर मॉनीटर में Picture tube होता है जो देखने में बिलकुल टीवी की तरह होता है यह Picture tube सी.आर.टी. कहलाती है CRT बहुत सस्‍ती तकनीक है
Cathode Ray Tube

CRT मोनीटर में एक Electron gun होता है जो की Electrons की Beam और Cathode Rays को उत्सर्जित करती है ये Electron beam, Electronic grid से पास की जाती है ताकि electron की Speed को कम किया जा सके CRT Monitor की Screen पर फास्फोरस की Coding की जाती है इसलिए जैसे ही electronic beam Screen से टकराती है तो Pixel चमकने लगते हैं और मोनीटरScreen पर डिस्‍पले दिखाई देने लगता है

LED (Light Emitting Diode)

वर्तमान समय में LCD (Liquid Crystal Display) के स्‍थान पर LED (Light Emitting Diode) का इस्‍तेमाल किया जा रहा है यह देखने में बिलकुल LCD Monitor की तरह ही लगते हैं लेकिन LED 1.5 watts की पावर इस्‍तेमाल करती है और ऑखों पर बहुत कम जोर डालती है LED Monitor LCD की तुलना में अधिक समय तक काम करते हैं LED को लाइट एमिटिंग डायोड भी कहा जाता है यह एक सेमीकंडक्टर डिवाइस होता है जो लाइट को एमिटिंग या उत्‍सर्जित करता है LED एक बहुत महत्वपूर्ण आविष्कार रहा है इसका इस्तेमाल बहुत ज्यादा मात्रा में लोगों के द्वारा किया जा रहा है
